1896 List Manual (LH2), 07/2016, A5E03263479A
F35804 (N, A) TM: CRC
Message value: %1
Message class: Hardware/software error (1)
Drive object: B_INF, TM120, TM150, TM31, TM54F_MA, TM54F_SL, VECTOR_G
Component: Terminal Module (TM) Propagation: BICO
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A checksum error has occurred when reading-out the program memory on the Terminal Module.
Fault value (r0949, interpret hexadecimal):
Difference between the checksum at POWER ON and the actual checksum.
Remedy: - check whether the permissible ambient temperature for the component is maintained.
- replace the Terminal Module.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE

Component: Terminal Module (TM) Propagation: BICO
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Internal parameter data is corrupted.
Alarm value (r2124, interpret hexadecimal):
01: EEPROM access error.
02: Too many blocks in the EEPROM.
Remedy: - check whether the permissible ambient temperature for the component is maintained.
- replace the Terminal Module 31 (TM31).
Reaction upon N: NONE

F35820 TM DRIVE-CLiQ: Telegram error
Message value: Component number: %1, fault cause: %2
Message class: Internal (DRIVE-CLiQ) communication error (12)
Drive object: B_INF, TM120, TM150, TM31, TM54F_MA, TM54F_SL, VECTOR_G
Component: Terminal Module (TM) Propagation: BICO
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communication error has occurred from the Control Unit to the Terminal Module involved.
Fault cause:
1 (= 01 hex):
Checksum error (CRC error).
2 (= 02 hex):
Telegram is shorter than specified in the length byte or in the receive list.
3 (= 03 hex):
Telegram is longer than specified in the length byte or in the receive list.
4 (= 04 hex):
The length of the receive telegram does not match the receive list.
5 (= 05 hex):
The type of the receive telegram does not match the receive list.
