Meaning/What you should do Message
CALIBRATION LOST The weighing constants stored in the EEPROM memory
have been corrupted. To rectify the problem either
re–calibrate the machine (See Section 7) or change the
main PCB (see Section 11). If you re–calibrate the
machine without changing the main PCB you must switch
the machine on and off a number of times to make sure the
problem does not occur again.
Note:
If the weighing system fails due to a problem with the
transducer or A/D PCB, the machine will power–up and
display either an underrange or overrange condition.
CANNOT USE TARE On a network with different capacity machines, you have
selected a PLU with stored tare which does not belong to
the machine. Select the correct PLU.
CHANGE ROLL ? You have changed from label to receipt mode or vice
versa. Check the correct type of printer roll is loaded.
CLEAR DISABLED The totals clear option is not available at your machine.
CLOSE DRAWER Displayed when the cash drawer alarm is activated. Close
drawer and turn alarm off. Only on machines configured
for Cash Drawer Detection.
COMMAND ERROR Indicates an error in the ISC communications protocol.
This can be due to a mixed network (that is: different
versions of software) or a software fault.
If the problem persists contact Avery Berkel head office
with a full description of the fault and a list of all software
firmware numbers.
COMPUTING FAULT Secure machines only. The software checks the internal
operation of the microprocessor. Indicates detection of an
internal computing fault. Change main PCB (see

CORRUPT PLU The PLU has developed a fault. Delete the PLU and
re–create it. Advise your local Avery Berkel service centre.

with a full description of the fault and a list of all software
firmware numbers.
DCU DISCONNECTED You are attempting to use the DCU without it being plugged
in. Plug in the DCU and try again.
DEPT NOT ON MAP You are dumping the PLU file for a sub department which
does not have any machines. Re–select a valid
department or assign a slave to the sub department.
