4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G130/G150
1804 List Manual (LH2), 04/2014, A5E03263479A
Remedy: Check the device to de-ionize the cooling liquid.
A49171 Cooling unit: Conductivity has exceeded the alarm threshold
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF
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.
A49172 Cooling unit: Conductivity actual value is not valid
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
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.
A49173 Cooling unit: Cooling liquid temperature has exceeded the alarm threshold
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The cooling liquid intake temperature has exceeded the specified alarm threshold.
Note:
The value for the alarm threshold depends on the power unit (hardware descriptive data, e.g. 42 ... 50 °C).
Remedy: Check the cooling system and the ambient conditions.
F49200 Excitation group signal fault
Message value: %1
Message class: General drive fault (19)
Drive object: VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The excitation sequence control signals a fault.
Fault value (r0949, interpret hexadecimal):
Bit 0:
When powered down or when powering down the excitation, the signal "excitation ready feedback signal" was not
received within the monitoring time.
Bit 1:
After an ON command, the signal "excitation ready feedback signal" was not received within the monitoring time.
Bit 2:
After the pulses were enabled, the signal "excitation operational feedback signal" was not received within the
monitoring time.
Bit 3:
The "excitation group signal fault" signal is present.
Bit 4:
The switch-on command for the excitation was reset, although pulse enable (r0899.11) is still available, or the
excitation current actual value has still not fallen below a minimum value.
