4 Faults and alarms
4.2 List of faults and alarms
F49154 (A) Cooling unit: Liquid leak is present
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The liquid leakage monitoring function has responded.
Caution:
If this fault is re-parameterized as an alarm then using other monitoring functions it must be ensured that when
cooling water is lost, the drive is powered down!
See also: r0267 (Cooling unit status word)
Remedy: - check the cooling system for leaks in the cooling circuit.
- check the wiring of the input terminal (Terminal Module) used to monitor leaking fluid.
Reaction upon A: NONE
Acknowl. upon A: NONE
F49155 Cooling unit: Power Stack Adapter, firmware version too old
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Reaction: OFF2
Acknowledge: POWER ON
Cause: The firmware version in the Power Stack Adapter (PSA) is too old and does not support the liquid cooling.
Remedy: Upgrade the firmware. Check EEPROM data.
F49156 Cooling unit: Cooling liquid temperature has exceeded the fault threshold
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The cooling liquid intake temperature has exceeded the specified fault threshold.
Note:
The value for the fault threshold depends on the power unit (hardware descriptive data, e.g. 52 ... 55 °C).
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
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 Cooling unit: Conductivity has exceeded the alarm threshold
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: Conductivity monitoring is set for the cooling liquid (r0267.7, from p0266[7]).
