F30045 Power unit: Supply undervoltage
Message class: Supply voltage fault (undervoltage) (3)
Message value: %1
Component: Power Unit
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: Power supply fault in the power unit.
- The v
oltag
e monitor signals an undervoltage fault on the module.
The following applies for CU31x:
- The voltage monitoring on the DAC board signals an undervoltage fault on the module.
For S120M, the following applies:
- This message is displayed for undervoltage or overvoltage.
Remedy: - Check the power supply of the power unit.
- Carry out a PO
WER ON (switch-o󹪜/switch-on) for the component.
- Replace the module if necessary.
A30046 Power unit: Undervoltage alarm
Message class: Power electronics faulted (5)
Message value: %1
Component: Power Unit
Response: NONE
Acknowledgment: NONE
Cause: Before the last restart, a problem occurred at the power unit power supply.
The v
oltag
e monitor in the internal FPGA of the PSA signals an undervoltage fault on the module.
Alarm value (r2124, interpret decimal):
Register value of the voltage fault register.
Remedy: - Check the 24 V DC voltage supply to power unit.
- Carry out a POWER ON (switc
h-o󹪜/switch-on) for the component.
- Replace the module if necessary.
A30048 Power unit: fan defective
Message class: External measured value / signal state outside the permissible range (16)
Message value: Fault cause: %1 bin
Component: Power Unit
Response: NONE
Acknowledgment: NONE
Cause: The feedback signal of a fan signals a fault, or there is a communication error with one or several fans.
- F
an defectiv
e.
- Fan blocked.
- Feedback signal error.
Alarm value (r2124, interpret binary):
Bit 0 = 1: heat sink fan
Bit 1 = 1: fan 1 inside the device
Bit 2 = 1: fan 2 inside the device
Bit 4 = 1: Internal communication error to one or several fans
Bits 16 to 31 are only for internal Siemens diagnostics.
