Reaction upon N: NONE
Acknowl. upon N: NONE
A34904 (F, N) VSM: EEPROM
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An error has occurred accessing the non-volatile memory on the Terminal Module.
Remedy: Replace the Terminal Module.
Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE
VECTOR: NONE
Acknowl. upon F: IMMEDIATELY (POWER ON)
Reaction upon N: NONE
Acknowl. upon N: NONE
A34905 (F, N) VSM: Parameter access
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The Control Unit attempted to write an illegal parameter value into the Voltage Sensing Module (VSM).
Remedy: - check whether the firmware version of the VSM (r0158) matches the firmware version of Control Unit (r0018).
- if required, replace the Voltage Sensing Module.
Note:
The firmware versions that match each other are in the readme.txt file on the CompactFlash card.

Acknowl. upon N: NONE
A34920 (F, N) VSM: Temperature sensor fault
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: When evaluating the temperature sensor, an error occurred.
Alarm value (r2124, interpret decimal):
1: Wire breakage or sensor not connected (KTY: R > 1630 Ohm).
2: Measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm).
Remedy: - check that the sensor is connected correctly.
- replace sensor.
