4 Faults and alarms
4.2 List of faults and alarms
Remedy: Check the cooling system and the ambient conditions.
A49170 Cooling unit: Alarm has occurred
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The cooling unit signals a general alarm.
Remedy: - check the wiring between the cooling unit and the input terminal (Terminal Module).
- check the external control device for the cooling unit.
A49171 (N) Cooling unit: Conductivity has exceeded the alarm threshold
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: Conductivity monitoring is set for the cooling liquid (r0267.7, from p0266[7]).
See also: p0261 (Cooling unit starting time 2), p0262 (Cooling unit fault conductivity delay time), p0266 (Cooling unit
feedback signals signal source), r0267 (Cooling unit status word)
Remedy: Check the device to de-ionize the cooling liquid.
Reaction upon N: NONE
Acknowl. upon N: NONE
A49171 (N) Cooling unit: Conductivity has exceeded the alarm threshold
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The conductivity of the cooling liquid has exceeded the selected alarm threshold (p0269[1]).
Note:
The threshold cannot be set higher than the fault threshold specified in the equipment description.
Remedy: Check the device to de-ionize the cooling liquid.
Reaction upon N: NONE
Acknowl. upon N: NONE
A49172 Cooling unit: Conductivity actual value is not valid
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: When monitoring the conductivity of the cooling liquid, there is a fault in the wiring or in the sensor.
Remedy: - check the wiring between the cooling unit and the Power Stack Adapter (PSA).
- check the function of the sensor to measure the conductivity.
