Alarm value Bit 0 - 7: Number of the affected component
(r2124): Bit 8 - 31: Reserved
Remedy: - Check for break in DRIVE-CLiQ or faulty contacts in connector.
- Check 24 V supply of affected component.
- Replace affected component.
F35891
CU DRIVE-CLiQ: Transition to cyclic mode
Reaction: OFF2
Cause: DRIVE-CLiQ communication between control unit and at least one other component is
defective.
Fault value Bit 0 - 7: Number of the affected component
(r0949): Bit 8 - 31: Reserved
Remedy: - Check firmware states of affected components.
- Replace affected component.
Acknowl.: Immediate
F35899
TM: Unknown fault
Reaction: NONE
Cause: A fault has occurred on the TM for which there is no name in the firmware. This fault may
occur when the TM firmware is more recent than the firmware on the CU.
Remedy: Replace TM. If nec. adapt the TM firmware version (r0158) to the firmware version used on
the CU.
Acknowl.: Immediate
A35900
TM DRIVE-CLiQ: Synchronization
Cause: TM cannot synchronize to DRIVE-CLiQ.
Remedy: Check DRIVE-CLiQ connections between CU and TM.
A35901
TM DRIVE-CLiQ: Communication faulted
Cause: Signal received by the TM via the DRIVE-CLiQ is of poor quality
Remedy: Check DRIVE-CLiQ connections between CU and TM.
A35903
TM: Error I2C bus
Cause: An error occurred on access via the TM-internal I2C bus.
Remedy: Replace TM.
A35904
TM: EEPROM
Cause: An error occurred while accessing the flash memory of the TM.
Remedy: Replace TM.
A35905
TM: Parameter access
Cause: CU has attempted to write an impermissible parameter value to the TM.
Remedy: Check whether the firmware version of the TM (r0158) matches that of the CU (r0018).
Replace. TM. The readme.txt file on the flash card states the matching TM firmware version
for a given CU firmware version.
A35920
TM: Temperature sensor error
Cause: An error has occurred while evaluating the temperature sensor.
Alarm value 1: Wire break or sensor not connected.
(r2124): 2: Short-circuit has occurred.
3: Measured resistance lies below permissible evaluation range.
4: No sensor selected.
5: Internal buffer does not contain the required number of stored values.
6: Negative difference voltage measured.
Remedy: - Check sensor connection.
- Replace sensor.
