ABS960+ Troubleshooting Guide
"Error Data Nil" message
The "Error Data Nil" message on the passenger panel means that power is applied, but no RS-485 data is received at the passenger panel. The centre two pins of the connector and cable are used for the communications. This issue can be associated with ...
Weight reading is drifting
Confirm that this happens when a weight is placed on the scale and not touched, and nobody is moving around the scales (movement of the floor/desk can be transmitted to the scale if these are touching the scale, which will appear as if the weight ...
Passenger panel is blank
If the operator panel is working, check/change the passenger display cable. Swap out the passenger panel.
Scale shows incorrect weight
Place a weight of around 40kg in the centre of the scale, note the reading, then move the weight to the four individual corners. Are the weight readings for the corners the same to within +/-0.2 kg? If yes, recalibrate the scales. If no, check the ...
Scale does not return to zero when weight is removed
There is a mechanical bind preventing the scale from freely settling to zero. Check for obstructions to the weigh scale and conveyor mounted on top. Ensure cables, desks and adjacent conveyor are not touching the scale. If the problem is not solved, ...
Printer connected to operator panel is not working
Press and hold the F4 button to enter the settings menu Press the “C” button (Next) to scroll to the RS-232 menu, and press “M-“ button to select Ensure that the Output is set for “Printer”. Use the F2 and F3 keys to change the selection Ensure baud ...
Operator panel switches off soon after it's powered up
This is because the remote power function is turned is on. Turn the unit on, press and hold the F4 button until you get into the set-up menu. The indicator will remain on while you scroll to in the I/O menu and change Input One from "Remote Power" ...
"Not enough weight" message displayed when trying to calibrate
This message is displayed when the scale Analogue to Digital (A to D) converter doesn't see enough change from zero to the calibration weight value. Normally this is a problem when using only 40 kg for calibration. Things to try: Try using 100 kg ...
Black dot on the operator panel display
The operator display has a black spot in the middle because the rear bracket has been fitted upside down, causing pressure to be transferred to the display. If the bracket is turned the right way up the black dot will disappear.
Passenger panel shows "Err Char Bad"
The data being sent from the operator panel is corrupted and the passenger panel is reporting the error as “Bad Char” or bad character received. There are no settings that could be wrong that will produce this error, and you will need to confirm if ...
"Difference is too small" message (during calibration)
The reason for the message is that the change in analogue output from the scale base between zero calibration and the span calibration value is too small. The most likely reason is that the amount of weight placed on the scale for span calibration is ...
Operator display shows scale divisions of 0.01 instead of 0.1kg
Remove the dip switch cover on the rear of the operator panel and return the position of Dip Switch 2 to “ON”.
"Bad addr" message on passenger panel
The command from the operator panel has a standardised format that includes an address byte. The message on the passenger panel indicates that the format received is unexpected. The fault could be with the operator panel, load cell cable or the ...
ADC fault or ADC fail
The “A to D” fault means that two identical Analogue to Digital conversions produced the same count number. Normally this would be impossible unless the Analogue to Digital (A to D) converter is faulty or the voltage readings from the scale base is ...
Screen shows ADC 2 error
This is usually a short circuit in the load cell cable, or an internal problem in the trimmer box. If the input signal from the load cells is shorted to the excitation voltage, then the scale will first read "Heavy Bag", then display the message "ADC ...
Changing display from kg to lb
Press and hold the F4 key down to get into the configuration menu (Dip switch 1 needs to be on, located under the small back cover on the rear of the indicator). Under the scale menu, scroll down using the F3 button until you find the menu "Allow ...
