Cause
For Compact PLUS units:
UCE lower switch
For Compact and chassis type units: UCE
Phase L2
For Compact PLUS AC/AC units: Pulse
resistance fault
For chassis type units: UCE Phase L3
A fault has occurred in the measured value
sensing system:
- (r949 = 1) Offset adjustment in phase L1 not
possible
- (r949 = 2) Offset adjustment in phase L3 not
possible.
- (r949 = 3) Offset adjustment in phases L1
and L3 not possible.
- (r949=65) Autom. Adjustment of the analog
inputs is not possible
Parameterizable external fault input 1 has
been activated.
Parameterizable external fault input 2 has
been activated.
A voltage failure has occurred during a
parameter task.
Incorrect operating status
A fault has occurred during the storage of
values in the EEPROM.
The available calculating time of the time slot
has been exceeded.
At least 10 failures of time slots T2, T3, T4 or
T5 (see also parameter r829.2 to r829.5)

Faults and Alarms
Counter-measure
- Check the converter outputs for earth fault
- Check the switch for "SAFE STOP" on
Compact units
- Check the converter outputs for earth fault
- Check the switch for "SAFE STOP" on
Compact DC/DC units and chassis units with
the option "SAFE STOP"
Fault in measured value sensing
Fault in power section (valve cannot block)
Fault on CU
- Check whether there is an external fault
- Check whether the cable to the
corresponding digital output is interrupted
- P575 (Src No ExtFault1)
- Check whether there is an external fault
- Check whether the cable to the
corresponding digital output is interrupted
- P576 (Src No ExtFault2)
Re-enter the parameter. The number of the
parameter concerned is indicated in fault value
r949.
Replace the control board (CUMC) or the unit
(Compact PUS).
Replace the control board (CUMC) or the unit
(Compact PLUS)
- Reduce pulse frequency
- Calculate individual blocks in a slower
sampling time
- The technology functions Synchronization
(U953.33) and Positioning (U953.32) must not
be enabled at the same time.
