Load Cell input mode

print

Load Cell mode is ideal for all weighing, torque, strain and force measurements.

It is easy to calibrate and has many useful features.

You only need a 4-wire connection for high performance cable resistance compensation, thanks to our new patented signal processor.

digital panel meter load cell connection
You can connect up to 4 x 350 Ohm or 8 x 700 Ohm load cells in parallel.

The meter constantly checks your system resistance to give you early warning of any unexpected changes caused by moisture in junction boxes, corroded connections etc.

If your cells are in a hazardous area, you only need to use 4 x Zener Barriers with this meter, where most other meters would need 6 barriers.

How to choose sensor type:  L.cEL

Unlock the calibration menu, set Ed.CF

1. Press buttons 1 and 2 together for at least 6 seconds.

The display will say:

      typE

2. Press the △ or ▽ button repeatedly until you see:

     L.cEL

3. Press  OK

You only need to do this procedure when you first install your meter or when you want to change the meter's sensor type.


digital panel meter front lens
L
c
E
L
kg




Unique Feature: This meter will automatically compensate for changes in cable resistance with a 4 wire connection. Most other meters need a 6 wire connection. You can also use it with passive zener barriers, in a 4 wire system.

How to choose a Calibration Method:

Direct Calibration is recommended, because it calibrates the whole system including thedisplay and the load cells and any leverage effects. You will put a known calibration weight on the platform and adjust the meter to read that weight exactly.

Theoretical Calibration is only recommended if you cannot apply a test weight to your system. You will enter details from the load cell calibration certificate.


Selection Method:
Unlock the calibration menu, select Ed.CF

Press button 1 and button 2 at the same time, for 3 seconds.

The display will briefly show  C.SrC (Calibration source).

It will then show either ...

Direct  dir.
or
Theoretical  thEo..

Press button 2 or button 3 to choose the calibration type you want.

Press  OK to save your choice.

Quick and Easy



Direct Calibration (Recommended)

Choose direct calibration if you will put known calibration weights on the system to calibrate the display. We recommend this calibration mode, because it allows you to calibrate your whole weighing system in one procedure.

Unlock the calibration menu, select Ed.CF

Press Button 1 for three seconds.
You should see  dir.
You may see  Theo.
If so, go back and select  dir

You will see  In.Lo. Apply the lowest load value, usually 0kg

To save your choice, press  OK

Then you will see  rd.Lo. Adjust the display to its desired reading for this load.

To save your choice, press  OK


Press Button 2 for three seconds.
You will see  In.Hi.
Apply the highest load value, ideally 100% of full load.

To save your choice, press  OK

You can calibrate with less load, with proportionally less accuracy.

You will see  rd.Hi.
Adjust the display to its desired reading for this load

To save your choice, press  OK

That completes the Direct Calibration.

We suggest that you check 0% load and some intermediate loads, to ensure your system is working as you wish.

This video shows how to calibrate with a known weight (direct calibration).

In this example, we start with an empty load cell platform and set the display to show 0.000.

We then put a known 5.000 kg weight on the load cell platform and adjust the display to show 5.000 kg.


Quick and Easy




How to change Decimal Point Position
It is easy to change the decimal point position during your calibration. In the example above, we calibrated for 0.000 to 5.000 kg.

Let us say we want to calibrate 0.00 to 5.00 kg...

During the stage where we adjust the high load reading, we can press button 2 for three seconds while we edit the value.

All decimal points will illuminate, with one decimal point brighter than the others.

Press Button 2 or Button 3 to change the position of the brightest decimal point.

Press OK when the brightest decimal point is where you want it.

You will see the decimal point is now in the new chosen position.

You can then continue to edit the numeric value as you wish.

further information This video demonstrates how to change the decimal point position.

Quick and Easy



rd.Hi.
Theoretical Calibration
Choose theoretical calibration if you will enter details from the load cell calibration certificate into the meter.

You do not need to connect the load cell to the meter for this calibration method.

This method is less accurate than the direct calibration method, because it does not include all the components of the weighing system.

How to calibrate your meter

There are 2 calibration methods available:

Direct Calibration method:

Direct calibration is more accurate, because it calibrates the whole system, including the sensor.

1. Connect your sensor to the meter and to your process.

You must be able to adjust the process to two precisely known values, ideally at 0% and 100% of your measurement range, but you can use any 2 well separated points.

You will adjust the meter to read those two calibration values.

2. If the meter is locked, unlock the calibration menu

3. Press 'Cal Lo' and 'Cal Hi' together for 3 seconds until you see 'C.Src' (calibration source)

4. Press the △ or ▽ button repeatedly until you see: 'dir' then press 'OK'


Example Calibration:

Calibrate the meter with an input signal range of 1.000 V to 9.000 V, to display 0.0 to 60.0

High Calibration point:
  In.Hi = 9.000 V
  rd.Hi = 60.0

Low Calibration point:
  InLo = 1.000 V
  rd.Lo = 0.0

We will also check the middle of the range at 5V input, to verify that the display shows 30.0

Method...



High calibration point
1. Press 'Cal Hi' button for 3 seconds.

2. The display will say 'dir' to confirm you are in Direct calibration made, and will then say 'InHi'.

3. Apply the high level calibration signal 9.000V in the example, and press 'OK'

4. The display will now briefly say 'rd.Hi' to confirm you are in the High Reading setting.

5. To set decimal point position, press 'Cal Hi' button again for 3 seconds and move the decimal point to the desired position with △ or ▽ buttons. Press 'OK' to save.

6. Press 'Digit' button to select each digit and edit with the △ or ▽ buttons to show 60.0 or your desired high reading. Press 'OK' when all digits are correct.


Low calibration point
7. Press 'Cal Lo' button for 3 seconds.

8. The display will say 'dir' to confirm you are in Direct calibration made, and will then say 'InLo'.

9. Apply the low level calibration signal 1.000V in the example, and press 'OK'

10. The display will now briefly say 'rd.Lo' to confirm you are in the Low Reading setting.

11. Press 'Digit' button to select each digit and edit with the △ or ▽ buttons to show 0.0 or your desired low reading. Press 'OK' when all digits are correct.


12. Apply 50% of input range, so 5.000V in the example and ensure the display reads 50% of display range, being 30.0 in the example.

The meter will lock itself automatically within 5 minutes, or immediately, if you switch the meter off then on again.

Quick and Easy


Theoretical Calibration method:

Theoretical calibration allows you to define two input and corresponding display values, without needing to connect a sensor to the display.

It is not as accurate as Direct calibration, because we do not include the sensor in the calibration, but it is useful as an approximate calibration method.

1. If the meter is locked, unlock the calibration menu

2. Press 'Cal Lo' and 'Cal Hi' together for 3 seconds until you see 'C.Src' (calibration source)

3. Press the △ or ▽ button repeatedly until you see: 'thEo' then press 'OK'


Example Calibration:

How to calibrate your meter

There are 2 calibration methods available:

Direct Calibration method:

Direct calibration is more accurate, because it calibrates the whole system, including the sensor.

1. Connect your sensor to the meter and to your process.

You must be able to adjust the process to two precisely known values, ideally at 0% and 100% of your measurement range, but you can use any 2 well separated points.

You will adjust the meter to read those two calibration values.

2. If the meter is locked, unlock the calibration menu

3. Press 'Cal Lo' and 'Cal Hi' together for 3 seconds until you see 'C.Src' (calibration source)

4. Press the △ or ▽ button repeatedly until you see: 'dir' then press 'OK'


Example Calibration:

Calibrate the meter with an input signal range of 4.000mA to 20.000mA, to display 0.0 to 60.0

High Calibration point:
  In.Hi = 20.000 mA
  rd.Hi = 60.0

Low Calibration point:
  InLo = 4.000 mA
  rd.Lo = 0.0

We will also check the middle of the range at 12mA input, to verify that the display shows 30.0

Method ...



High calibration point
1. Press 'Cal Hi' button for 3 seconds.

2. The display will say 'dir' to confirm you are in Direct calibration made, and will then say 'InHi'.

3. Apply the high level calibration signal 20.000mA in the example, and press 'OK'

4. The display will now briefly say 'rd.Hi' to confirm you are in the High Reading setting.

5. To set decimal point position, press 'Cal Hi' button again for 3 seconds and move the decimal point to the desired position with △ or ▽ buttons. Press 'OK' to save.

6. Press 'Digit' button to select each digit and edit with the △ or ▽ buttons to show 60.0 or your desired high reading. Press 'OK' when all digits are correct.


Low calibration point
7. Press 'Cal Lo' button for 3 seconds.

8. The display will say 'dir' to confirm you are in Direct calibration made, and will then say 'InLo'.

9. Apply the low level calibration signal 4.000mA in the example, and press 'OK'

10. The display will now briefly say 'rd.Lo' to confirm you are in the Low Reading setting.

11. Press 'Digit' button to select each digit and edit with the △ or ▽ buttons to show 0.0 or your desired low reading. Press 'OK' when all digits are correct.


12. Apply 50% of input range, so 12.000mA in the example and ensure the display reads 50% of display range, being 30.0 in the example.

The meter will lock itself automatically within 5 minutes, or immediately, if you switch the meter off then on again.
Quick and Easy


Theoretical Calibration method:

Theoretical calibration allows you to define two input and corresponding display values, without needing to connect a sensor to the display.

It is not as accurate as Direct calibration, because we do not include the sensor in the calibration, but it is useful as an approximate calibration method.

1. If the meter is locked, unlock the calibration menu

2. Press 'Cal Lo' and 'Cal Hi' together for 3 seconds until you see 'C.Src' (calibration source)

3. Press the △ or ▽ button repeatedly until you see: 'thEo' then press 'OK'

Higher precision connection method using an external fixed cold junction. Triple-point cells or oven-controlled 45 Deg C references are commonly used.

Thermocouple connection to digital panel meter with Fixed CJ compensation

This method is useful when the cable length from thermocouple to meter is long, because you can use lower cost copper for much of the cabling distance, instead of more costly extension cable.

More importantly though, the environment of the cold junction can be more precisely defined than the typical ambient conditions at the back of a meter in a general purpose control panel. This has the benefit of higher precision and stability under changing ambient temperature conditions.

Our rate measuring system uses the concept of 'bins', which is very user-friendly and flexible.

A bin can be filled with the number of counted pulses it receives. You can set the time during which a bin is open. This is shown as t in the diagram.

You can also specify a number of bins to use in your rate measurement, from 1 to 99. In the diagram we have chosen 3 bins, set by the bn.03 parameter.

In this case, we update the display with the number of counts received in the last 3 bins.

If we set t to be 20 seconds, we will show the rate in items per minute, updated every 20 seconds...

So at point a, the display will show 14 (6 + 3 + 5)
So at point b, the display will show 10 (3 + 5 + 2)
So at point c, the display will show 12 (5 + 2 + 5)
So at point d, the display will show 11 (2 + 5 + 4)

Lineariser

print



Introduction

The lineariser is easy to use. You can switch it on or off at any time, so you can compare linearised and non-linearised responses.

It is located at the end of the display process, so you can enter readings which the un-linearised display shows, and the ideal readings you would like the display to show.

It can linearise all physical displayed values, including rate, total, temperature, load, resistance etc., but excluding time.

It makes a curve having from 3 up to 31 points.

INT5 lineariser location in the signal chain

Examples: You can use the lineariser function to:-

  • Improve the precision of a weighing system which has repeatable non-linearity.
  • Use a liquid pressure sensor at the bottom a curved tank to show actual liquid volume
  • Convert a 4-20mA power factor signal to read signed power factor (4-12mA = -0.5 to -1, 12-20mA = +1 to +0.5)
  • Convert differential pressure across an orifice plate or weir to show flow rate
  • etc...

You can view and edit any part of the lineariser table.

1. Prepare your data

Before you enter any values, record what the display shows, without linearising, at several points and what you want it to show.

For example, in a weighing system, the engineer checked various readings with test weights and wrote down these results...

Adding load: Results with Lineariser off

StepTest Weight (kg)Displayed value (kg)
1:0.00.0
2:100.0100.2
3:200.0200.5
4:300.0300.3
5:400.0400.1
6:500.0500.1


He tested in the reverse direction also, to ensure the errors were repeatable.

Removing load: Results with Lineariser off

StepTest Weight (kg)Displayed value (kg)
7:500.0500.1
8:400.0400.1
9:300.0300.3
10:200.0200.5
11:100.0100.2
12:0.00.0


We can see that the errors are repeatable, they are the same when we add or remove weight, so can be improved with the lineariser.

Note:

Any errors which are not repeatable are normally caused by mechanical problems such as worn or poorly lubricated pulley bearings, loose load cell mountings, moisture in connection boxes or accumulated material which is interfering with the free movement of the load cells.

Non-repeatable errors cannot be corrected with the lineariser - they must be corrected physically.


We will write down our plan for the lineariser...

Our linearisation table

This table is used in the video, at the end of this page.

Alarm Relay Output Options

print

Use alarm relays for control, warning and shutoff in many industrial processes.

The INT5 has fail-safe alarms. If power is lost to the meter or if the microprocessor fails, the alarms will be active.

Choose from several output types:

Version SPCO:
Mechanical relay outputs: (most popular)

The contacts will be in this position when no power is connected to the device.
mechanical alarm output relay connectors


Version SSAC:
AC Solid state relay outputs:

The contacts will be open when no power is connected to the device.
solid state alarm output relay connectors


Version SSDC:
DC Solid state relay outputs:

The contacts will be open when no power is connected to the device.
solid state alarm output relay connectors


Each relay is independent and can have a different mode to the other relays.

A status LED, AL1, AL2, AL3 or AL4 shows the status of each alarm channel.

The status LED has 3 colour states...
Yellow means the setpoint has been triggered but the alarm relay has not yet been activated. (if a timer delay is set, for example)

Red means the alarm relay is active.

Not lit means there is no alarm condition and the alarm relay is not active.

You can also make the numeric display change colour whenever the input signal is in an alarm condition. The most recent active alarm will determine the alarm display colour.

1. Alarm modes:
Your meter has many useful alarm modes to help with control and warning applications. Click or tap on any of the modes for more information.


High alarm - alarm occurs if the input signal reaches or exceeds the Setpoint value.


Low alarm - alarm occurs if the input signal falls to or below the Setpoint value.


Pump Control High alarm - alarm occurs if the input signal reaches or exceeds the Upper Setpoint value SEt.H . The relay will stay in that state until the signal drops to or below the Lower Setpoint value SEt.L


Pump Control Low alarm - alarm occurs if the input signal reaches or falls below the Lower Setpoint value SEt.L . The relay will stay in that state until the signal rises to or above the Upper Setpoint value SEt.H


In Band alarm - alarm occurs if the input signal goes within two limits. The lower limit is set with SEt.L and the higher limit is set with SEt.H


Out Band alarm - alarm occurs if the input signal goes outside two limits. The lower limit is set with SEt.L and the higher limit is set with SEt.H


High alarm with manual In-flight compensation. Alarm occurs if the input signal reaches or exceeds the Setpoint value, less the expected in-flight (dribble) amount, which is manually set to a fixed amount.


Low alarm with manual In-flight compensation. Alarm occurs if the input signal reaches or falls below the Setpoint value, plus the expected in-flight (dribble) amount, which is manually set to a fixed amount.


High alarm with automatic adaptive In-flight compensation. Alarm occurs if the input signal reaches or exceeds the Setpoint value, less the expected in-flight (dribble) amount, which is automatically set, according to previous alarm overshoot.


Low alarm with automatic adaptive In-flight compensation. Alarm occurs if the input signal reaches or falls below the Setpoint value, plus the expected in-flight (dribble) amount, which is automatically set, according to previous alarm overshoot.


Latching High alarm - alarm occurs if the input signal reaches or exceeds the Setpoint value. Remains in alarm even if signal returns to a non-alarm level. Can be reset using the reset logic input port.


Latching Low alarm - alarm occurs if the input signal reaches or falls below the Setpoint value. Remains in alarm even if signal returns to a non-alarm level. Can be reset using the reset logic input port.


Pulsed High alarm - alarm occurs if the input signal reaches or exceeds the Setpoint value. The output will pulse once only, for a duration set with t.Out, in a range from 0.1 to 99.9 seconds. The alarm annunciator LED will be red for the duration of the pulse and will be switched off at all other times.


Pulsed Low alarm - alarm occurs if the input signal reaches or falls below the Setpoint value. The output will pulse once only, for a duration set with t.Out, in a range from 0.1 to 99.9 seconds. The alarm annunciator LED will be red for the duration of the pulse and will be switched off at all other times.


This channel is turned off and will not activate its alarm relay under any conditions.





View alarm setpoints:
To view the setpoint level for each alarm relay, briefly press the Alarm button, repeatedly.

The display will be dimmed and the alarm setpoint is represented by the numeric value.

The alarm channel identifier will be flashing. See the example below, where Alarm channel 2 has a setpoint of 1234 ...

High Alarm mode

print



Creates an alarm if the input signal equals or exeeds a setpoint.

Example :
The meter will switch a pump off when the liquid reaches the alarm setpoint level.

If the tank does not have straight sides, you can use the meter's lineariser to convert pressure to volume.

High alarm control

To configure the alarm type
1. Unlock the alarms menu

2. Press the Alarms button repeatedly until your chosen alarm channel annunciator LED flashes. We use Alarm 2 (AL2) for this example.

3. Press and hold the Alarms button for at least 6 seconds until you see ...

digital panel meter front lens
A
C
F
g


You can now view and change the following alarm features...

Use the △ or ▽ buttons to move up or down the list and press OK when you see Hi, to select this mode.




2. Colour when in alarm state
Use the △ or ▽ buttons to move up or down the list and press OK to select.

CoL.G = Green
CoL.Y = Yellow
CoL.r = Red

The highest numbered alarm channel will have the highest colour priority.

If tripped, AL2 will dominate AL1 for colour
If tripped, AL3 will dominate AL2 and AL1 for colour
If tripped, AL4 will dominate AL3, AL2 and AL1 for colour

So, if Alarm 1 has tripped and its alarm colour is Yellow, and Alarm 2 has tripped and its alarm colour is red, the display will be red.

If no alarms are active, the display colour will be the colour chosen in the Colour Setting section.

If you want visual colour cues to critical alarms, place the most critical alarms on the higher alarm channels.




3. Relay energised or de-energised when in alarm
Use the △ or ▽ buttons to move up or down the list and press OK to select.

rL.dE means the relay will de-energise when an alarm condition occurs. This is the recommended option, because it gives failsafe relay action. You will get the same condition if you lose power to meter, which is generally the safest response. On the diagram below, we show relays which de-energise on trip with a green tick.

rL.En means the relay will energise when an alarm condition occurs. This is normally not the best option, because it is not failsafe. You will never get an alarm response if you lose power to the meter, which could be dangerous, so we mark this response with a red cross.






4. Source of comparison data
You can choose which available data within the meter is compared to each alarm setpoint.

nEtt
Only the Nett value will be compared with this alarm setpoint.

GroS
Only the Gross value will be compared with this alarm setpoint.

PEA.G
Only the Peak (maximum) Gross value will be compared with this alarm setpoint.

VAL.G
Only the Valley (minimum) Gross value will be compared with this alarm setpoint.

PEA.n
Only the Peak (maximum) Nett value will be compared with this alarm setpoint.

VAL.n
Only the Valley (minimum) Nett value will be compared with this alarm setpoint.

tARE
Only the Tare value will be compared with this alarm setpoint.

CJ t
Only the ambient temperature sensor value will be compared with this alarm setpoint.




5. Set.Pt
This is the value which the measurement will be compared to. You can edit it using the Digit button to select each digit, and the △ or ▽ buttons to increase or decrease the value of a digit.

To set a negative setpoint, use the Digit button to select the left-hand digit and press the ▽ button to show the negative symbol. eg. -XXX.XX.

You can access the Set.Pt setting either from within the main A.CFG Alarm Configuration, or by pressing the alarm button for only 3 seconds when your chosen alarm annunciator is flashing.




6. Hyst
Hysteresis is often used in filling or simple control applications to prevent the alarm relay from repeatedly energising and de-energising when the signal is near to the setpoint.

If hysteresis is set to 0, the alarm will reset as soon as the signal changes to a level outside the alarm limit.

For example if the signal represents water level and there is turbulence in the liquid, you may find the alarm relay repeatedly switches on and off, even though the average level is not changing. You can prevent this with hysteresis.

If you have a high setpoint of 100.00 and no hysteresis, the alarm will occur at 100.00 and will reset at 99.99.

If you set hysteresis to 0.30, the alarm will occur at 100.0 and will only reset when the measurement drops below 99.70.

Choose the amount of hysteris you need, according to the amount of variability or instability in your signal.

High Alarm relay action

In this example, the setpoint is at 57 and we have set hysteresis to 12.

This means the alarm will trip at 57 and will only reset if the input falls to or below 57-12 = 45.




7. On.tr
This sets a delay, before which the alarm relay will trip, when an alarm condition occurs. You can set it from 00.0 to 99.9 seconds.

on delay before trip

It is useful if your measurement has noise or transient alarm conditions and you do not want brief false alarms.

It requires that the alarm condition remains present for the whole  On.tr  period, before the alarm output will change.

If your trip has this delay set, and an alarm condition occurs, you will see that the alarm annunciator LED will first turn yellow, to indicate that the trip condition has been triggered.

Then after the delay period has passed, the alarm relay will trip and the annunciator LED will turn red.




8. t.out
This sets a timed pulse output duration on your alarm relay. You can set it from 00.0 to 99.9 seconds.

off delay before trip, fixed duration, repeat

You would normally use this setting and On.tr. If you set On.tr to 01.0 and set t.Out to 05.0, the alarm will activate after 1 second, will remain active for 5 seconds, then be inactive for 1 second, active for 5 and so on, for the duration that the alarm is present. The annunciator LED will be yellow during inactive alarm relay periods and red when the alarm relay is active.

If you alarm mode is PuL.H or PuL.L, then you will only get one pulse, whose duration is set by t.Out and it may be delayed by a period set in On.tr. The alarm condition must exist for longer than On.tr for the relay to change state.

off delay before trip






9. OFF.t
This sets a delay, before which the alarm relay will reset, when coming out of an alarm condition. You can set it from 00.0 to 99.9 seconds.

off delay after trip

If your trip has this delay set, and an alarm condition ends, then after the delay period has passed, the alarm relay will reset and the red annunciator LED will turn off.

This sets a delay, before which the alarm relay will trip, when an alarm condition occurs. You can set it from 00.0 to 99.9 seconds.

on delay before trip low

It is useful if your measurement has noise or transient alarm conditions and you do not want brief false alarms.

It requires that the alarm condition remains present for the whole  On.tr  period, before the alarm output will change.

If your trip has this delay set, and an alarm condition occurs, you will see that the alarm annunciator LED will first turn yellow, to indicate that the trip condition has been triggered.

Then after the delay period has passed, the alarm relay will trip and the annunciator LED will turn red.




8. t.out
This sets a timed pulse output on your alarm relay. You can set the duration from 00.0 to 99.9 seconds.

off delay before trip, fixed duration, repeat

You would normally use this setting and On.tr.

Example:
Set On.tr = 01.0
Set t.Out = 05.0
The alarm will activate after 1 second, will remain active for 5 seconds, then be inactive for 1 second, active for 5 and so on, for the duration that the alarm is present.

The annunciator LED will be yellow during inactive alarm relay periods and red when the alarm relay is active.

If your alarm mode is PuL.H or PuL.L, then you will only get one pulse, whose duration is set by t.Out and it may be delayed by a period set in On.tr. The alarm condition must exist for longer than On.tr for the relay to change state.

9. OFF.t
This sets a delay, before which the alarm relay will reset, when coming out of an alarm condition. You can set it from 00.0 to 99.9 seconds.

off delay after trip low

If your trip has this delay set, and an alarm condition ends, then after the delay period has passed, the alarm relay will reset and the red annunciator LED will turn off.

Pump Control High Alarm mode

print



Creates an alarm if the input signal reaches or goes above a setpoint SEt.H. Resets the alarm if the input signal goes below a minimum setpoint SEt.L

Example :
The meter will switch the pump off when the liquid reaches the alarm maximum setpoint level SEt.H. It will only switch the pump on again when the level has dropped to a minimum setpoint SEt.L.

If the tank does not have straight sides, you can use the meter's lineariser to convert pressure to volume.

High alarm pump control

To configure the alarm type
1. Move the rear switch A to the UP position

2. Press the Alarms button repeatedly until your chosen alarm channel annunciator LED flashes. We use Alarm 2 (AL2) for this example.

3. Press and hold the Alarms button for at least 6 seconds until you see ...

digital panel meter front lens
A
C
F
g


You can now view and change the following alarm features...

Use the △ or ▽ buttons to move up or down the list and press OK when you see PC.Hi, to select this mode.




2. Colour when in alarm state
Use the △ or ▽ buttons to move up or down the list and press OK to select.

CoL.G = Green
CoL.Y = Yellow
CoL.r = Red

The highest numbered alarm channel will have the highest colour priority.

If tripped, AL2 will dominate AL1 for colour
If tripped, AL3 will dominate AL2 and AL1 for colour
If tripped, AL4 will dominate AL3, AL2 and AL1 for colour

So, if Alarm 1 has tripped and its alarm colour is Yellow, and Alarm 2 has tripped and its alarm colour is red, the display will be red.

If no alarms are active, the display colour will be the colour chosen in the Colour Setting section.

If you want visual colour cues to critical alarms, place the most critical alarms on the higher alarm channels.




3. Relay energised or de-energised when in alarm
Use the △ or ▽ buttons to move up or down the list and press OK to select.

rL.dE means the relay will de-energise when an alarm condition occurs. This is the recommended option, because it gives failsafe relay action. You will get the same condition if you lose power to meter, which is generally the safest response. On the diagram below, we show relays which de-energise on trip with a green tick.

rL.En means the relay will energise when an alarm condition occurs. This is normally not the best option, because it is not failsafe. You will never get an alarm response if you lose power to the meter, which could be dangerous, so we mark this response with a red cross.






4. Source of comparison data
You can choose which available data within the meter is compared to each alarm setpoint.

nEtt
Only the Nett value will be compared with this alarm setpoint.

GroS
Only the Gross value will be compared with this alarm setpoint.

PEA.G
Only the Peak (maximum) Gross value will be compared with this alarm setpoint.

VAL.G
Only the Valley (minimum) Gross value will be compared with this alarm setpoint.

PEA.n
Only the Peak (maximum) Nett value will be compared with this alarm setpoint.

VAL.n
Only the Valley (minimum) Nett value will be compared with this alarm setpoint.

tARE
Only the Tare value will be compared with this alarm setpoint.

CJ t
Only the ambient temperature sensor value will be compared with this alarm setpoint.




5. Set.H and SEt.L
These are the values which the measurement will be compared to. You can edit them using the Digit button to select each digit, and the △ or ▽ buttons to increase or decrease the value of a digit.

To set a negative setpoint, use the Digit button to select the left-hand digit and press the ▽ button to show the negative symbol. eg. -XXX.XX.

7. On.tr
This sets a delay, before which the alarm relay will trip, when an alarm condition occurs. You can set it from 00.0 to 99.9 seconds.

It is useful if your measurement has noise or transient alarm conditions and you do not want brief false alarms.

It requires that the alarm condition remains present for the whole  On.tr  period, before the alarm output will change.

If your trip has this delay set, and an alarm condition occurs, you will see that the alarm annunciator LED will first turn yellow, to indicate that the trip condition has been triggered.

Then after the delay period has passed, the alarm relay will trip and the annunciator LED will turn red.




8. t.out
This sets a timed pulse output duration on your alarm relay. You can set it from 00.0 to 99.9 seconds.

off delay before trip, fixed duration, repeat

You would normally use this setting and On.tr. If you set On.tr to 01.0 and set t.Out to 05.0, the alarm will activate after 1 second, will remain active for 5 seconds, then be inactive for 1 second, active for 5 and so on, for the duration that the alarm is present. The annunciator LED will be yellow during inactive alarm relay periods and red when the alarm relay is active.

If you alarm mode is PuL.H or PuL.L, then you will only get one pulse, whose duration is set by t.Out and it may be delayed by a period set in On.tr. The alarm condition must exist for longer than On.tr for the relay to change state.

off delay before trip






9. OFF.t
This sets a delay, before which the alarm relay will reset, when coming out of an alarm condition. You can set it from 00.0 to 99.9 seconds.

off delay after trip

If your trip has this delay set, and an alarm condition ends, then after the delay period has passed, the alarm relay will reset and the red annunciator LED will turn off.

Ambient Temperature Sensor

print

There is a temperature sensor on the rear of the meter, between the analogue input terminals and the contact closure input terminals.

It gives cold junction compensation for thermocouple measurements, but can also show the meter's ambient temperature when in another measurement mode.

This reading cannot be scaled or offset, it is a fixed internal calibration.

Available for alarm and retransmission:
It can be compared to an alarm setpoint, to warn if the ambient temperature is too low or too high.

Other setpoints can be used for general measurement control or alarm of the meter's main measurment.

It can be re-transmitted from one of the meter's data ports or from the analogue output.

1. Unlock the configuration menu

2. Press Buttons 3 and 4 at the same time, for 3 seconds.

3. The meter will show dISP. Then it will show the existing display parameter.

Use Button 2 or Button 3 to view the list of available display parameters, until you see CJ t

Press Button 4 repeatedly until you see the local temperature to 2 decimal places, degrees C.

It will display the meter's rear ambient temperature in degrees C, in the format  XX.XX

Permanent Display Value

print



You can set the display to permanently show one of several different sources of data.

For example, you can configure the display to permanently show the peak, or valley, or the nett value, or the gross value, or the tare value, etc.

In most measurements, the Nett value is the most appropriate, so this is the default.

Unlock the calibration menu, select Ed.CF

Press Button 3 and Button 4 together for 3 seconds. The  dISP promp will appear.

You can use the △ or ▽ buttons to set one of the following permanent display values. Press 'OK' to save :




 Nett The Nett value
This is the value after you tare the display.

For example, if the meter reading shows 12.5 and you tare it, the display will show 0.0
This is the most common display choice in most weighing applications.




 Gros The Gross Value
This is the amount the measurement has risen by since it was calibrated at 0.

The displayed value will not change if you tare the meter.

This is common in applications where you want to see the total amount of some measurement, such as silo content.




 PEA.G The Peak Gross value
This value will track the rising gross value and will remain at the highest level, since it was last reset.

This is useful in such applications as over-temperature monitoring, flood level monitoring, mechanical overload / destructive test monitoring.




 VAL.G The Valley Gross Value
This value will track the falling gross value and will remain at the lowest level, since it was last reset.

This is useful in such applications as under-temperature monitoring, storage container depletion monitoring, minimum ground-water level detection etc.




 PEA.n The Peak Nett value
This shows the highest Nett value since the peak was last reset.




 VAL.n The Valley Nett value
This shows the lowest Nett value since the valley was last reset.




 tArE The Tare value
This shows the tare amount.

For example, in a weighing application, your platform has nothing on it and reads 0

You place an empty container weighing 78kg on the platform and the display reads 78.

You tare the display to 0, ready to weigh how much material you put in the container.

The Tare value will remain at 78kg, even while you fill or empty the container.




 CJ.t The Cold Junction Temperature
There is a temperature sensor on the rear of the meter which compensates for thermocouple cable ambient temperature errors.

You can display this temperature permanently, if you want to show the temperature inside the enclosure.

The meter can continue its main measurement / control function in the background.




 P.Frq The Power Frequency
If you meter is AC powered and includes the Power Frequency monitoring option, you can set the display to show power frequency, while the rest of the meter monitors and reacts to the main measurment input signal, which could be temperature, speed, total etc.

Mean Time Before Failure

print

High temperature is the main enemy of electronic devices.

This is because electrolytic capacitors, which are the components most likely to fail, age faster at higher temperature.

For best reliability, operate your displays in an environment where the temperature around the meter is less than 50C, ideally between 10 to 30C.

When you install the meter in a cabinet, the internal temperature may be many degrees higher than the temperature outside the cabinet.

We have calculated worst case MTBF when all possible options are installed in the meter, all operating at maximum power dissipation.

This means all relays energised, analogue output feeding into a Zero-Ohm load, excitation supply fully loaded to its rated current capacity, RS485 ports transmitting at high baud rate into 32 loads to

Figures are for altitude less than 2500 m. Higher altitude has lower air density with less air-cooling capacity.

Water vapour condensation is not included in these calculations due to its often unpredictable effect.

The installation must be designed to prevent water condensation inside the meters.

Stabilisation

print



stabilisation

This function helps you to stabilise a reading which is moving because of input signal fluctuations.

The more stabilisation you add, the slower will be the display's response, so some compromise is required between stability and speed.

Unlock the configuration menu

Press Buttons 2 and 3 together for 3 seconds.

Press OK repeatedly, until you see  F00.0 or similar.

You can edit the stability function value from  F00.0  to  F99.9  seconds.

A value of  F05.0,  for example, will average the reading over a 5 second period, updating every 0.1 second.

If you make a step change to the input with  F05.0,  the display will ramp linearly to the new value, taking 5 seconds to reach it.

Use the smallest value which provides sufficient stability.

Press OK repeatedly to return to the normal display mode.

further information This video demonstrates how to adjust the stabilisation.

Automatic Drift Cancelling

print



Drift cancelling is useful if your display reads 0 most of the time.

This is common in weighing applications, destructive test force applications etc.

Temperature changes can cause drift in the sensor and display.

While the display is near 0, we regularly check the reading. If it drifts by a small amount which you can define, in a certain time which you can define, we will reset the display to 0.

Unlock the configuration menu

Press Button 3 and Button 4 together for 3 seconds.

Press OK repeatedly, until you see drF.x

Press button 2 to change the display to drF.1

To define the maximum amount of drift you will accept, edit drF.A

To define how often you will check for drift, in seconds, edit drF.t

Press OK repeatedly to return to the normal display mode.

Then move the lockout switch ON to activate the automatic drift correction.

further information This video demonstrates how to adjust the automatic drift cancellation.

In this example, we will accept up to 5 counts of drift, and we check for drift every 10 seconds.

Any drift up to and including 5 counts will be automatically re-set to 0.

Any movement greater than 5 counts within 10 seconds will be considered as a valid process change and will not be re-set.

When you have finished, you must move the rear calibration lockout switch to ON, to allow the drift correction to function.

The video shows several corrections and it demonstrates that a process change larger than 5 counts is not affected.

Fault Finding

print

1. Display is reading the wrong value.

The display can be set to show several different sources of data, not only from the real-time input signal.

For example, you can configure the display to show only the peak reading, or valley reading, or the meter's ambient temperature, or the nett value, or the gross value, or the tare value, etc.

In most measurements, the Nett value is the most appropriate, but check that the 'dISP' value is appropriate for your application.

[ Detailed Information ]

Unlock the calibration menu, select Ed.CF

Press Button 3 and Button 4 together for 3 seconds.

The  dISP value would normally be set to  Nett , but you can set it to any of the available options to best suit your application.



2. I cannot unlock my meter.

To unlock the meter, the display must be in normal running mode.

You can not unlock the meter while you are viewing alarm information.

Check that you have not accidentally pressed the 'Alarms' button before you try to unlock the meter.

If you are viewing alarms, one of the square LEDs marked AL1, AL2, AL3 or AL4 will be flashing yellow.

Press the 'Alarms' button repeatedly to return to normal viewing and try again.




3. The rear contact closure inputs are not working.

Possible reason 1:
The Tare, Reset, peak/valley, nett/gross contact closure inputs only function when the meter is locked.

If you have just been configuring your meter, it will remain unlocked for 5 minutes, then will automatically lock.

If you want to lock the meter immediately, switch it off, wait 5 seconds, then switch it on again.

Your contact closure inputs should then function correctly.

Possible reason 2:
If you use switches with silver-plated contacts, these can fail open-circuit due to tarnishing of the contact surfaces, especially in atmospheres containing sulphur compounds.

For all low-level signal switching applications, we recommend gold plated contacts, which remain functional in sulphurous atmospheres, and are ideal for switching low level signals.



4. I cannot reset my peak or valley display value.

To reset peak or valley, the meter must be locked and you must be viewing the normal display value.

If you want to reset using the front reset button, and you have enabled it to be active, press it for 3 seconds.

If you want to reset using the rear reset contact closure, and you have enabled it to be active, close it for 3 seconds.





5. I don't know how to lock my meter.

To lock the meter quickly, switch it off, wait 5 seconds, then switch it on again.

The meter will always be locked when you switch it on.

If you forget to switch it off and on, it will automatically lock itself 5 minutes after you make your last adjustment to a setting in the meter.

You can easily tell if your meter is locked - look at the the unlock icon. The LED it points to will be permanently unlit.
