Siemens SINAMICS S210 - Power Unit: Fan Has Reached the Maximum Operating Hours; Power Unit: Overvolt 24;48 V; Power Unit: Overvolt 24;48 V Alarm

Cause: For the power unit power supply, the lower threshold has been violated.
Alarm value (r2124, interpret hexadecimal):
yyxxxx hex: yy = channel, xxxx = voltage [0.1 V]
yy = 0: 24 V power supply
yy = 1: 48 V power supply
Remedy: - check the power supply of the power unit.
- carry out a POWER ON (switch-off/switch-on) for the component.
Reaction upon F: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A30042 Power unit: Fan has reached the maximum operating hours
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The maximum operating time of at least one fan will soon be reached, or has already been exceeded.
Alarm value (r2124, interpret binary):
Bit 0 = 1:
The operating hours counter of the heat sink fan will reach the maximum operating time in 500 hours.
Bit 1 = 1:
The wear counter of the heat sink fan has reached 99 %. The remaining service life is 1%.
Bit 2 = 1:
The operating hours counter of the heat sink fan has exceeded the maximum operating time - and/or the wear counter
has exceeded 100%.
Bit 8 = 1:
The operating hours counter of the fan inside the device will reach the maximum operating time in 500 hours.
Bit 10 = 1:
The operating hours counter of the fan inside the device has exceeded the maximum operating time.
Remedy: For the fan involved, carry out the following:
- replace the fan.
- reset the operating hours counter (p0251, p0254).
F30043 Power unit: Overvolt 24/48 V
Message value: Channel: %1, voltage: %2 [0.1 V]
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: For the power unit power supply, the upper threshold has been violated.
Fault value (r0949, interpret hexadecimal):
yyxxxx hex: yy = channel, xxxx = voltage [0.1 V]
yy = 0: 24 V power supply
yy = 1: 48 V power supply
Remedy: Check the power supply of the power unit.
A30044 (F) Power unit: Overvolt 24/48 V alarm
Message value: Channel: %1, voltage: %2 [0.1 V]
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
