Fault during an internal self-test.
Reset the fault; switch the mains voltage off and on again if necessary.
Check all fuses in the device.
Check the curve points of the main and monitoring processors for irregularities.
Remote software: Curve table and/or set value graphic.
If the display remains dark or shows confusing characters, some or all of the LEDs
will light up and faults 111 and 140 will appear.
After the exchange of an EPROM or RAM:
- Remove the processor pc board
Check the components for the correct polarity (all notches point in the same direc-
tion).
Check whether all components are properly inserted (e.g., whether any prongs are
bent), and press them in firmly if necessary.
Check the proper seat of the processor card connection to the backplane.
Check the proper seat of the power supply card connection to the backplane.
If the fault occurs only sporadically, a software update to at least Version 5.7 may
help.
If fault messages are constantly appearing one after the other
exchange the
device or the respective card.

Fault during an internal self-test.
Reset the fault; switch the mains voltage off and on again if necessary.
In the case of the main and monitoring processors, the detection of the digital input
signals takes place at slightly different times.A signal change is present only long
enough for the main processor to detect it, but not the monitoring processor.
Check the signal sequence.

The monitoring processor checks whether the current correction values lie within
the set range.
Check the correction range.
