Acknowl. upon F: IMMEDIATELY (POWER ON)
A30042 Power unit: Fan has reached the maximum operating hours
Message value: %1
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The maximum operating time of at least one fan will soon be reached, or has already been exceeded.
Fault value (r0949, interpret binary):
Bit 0: heat sink fan will reach the maximum operating time in 500 hours.
Bit 1: heat sink fan has exceeded the maximum operating time.
Bit 8: internal device fan will reach the maximum operating time in 500 hours.
Bit 9: internal device fan has exceeded the maximum operating time.
Note:
The maximum operating time of the heat sink fan in the power unit is displayed in p0252.
The maximum operating time of the internal device fan in the power unit is internally specified and is fixed.
Remedy: For the fan involved, carry out the following:
- replace the fan.
