6.5.1 Monitoring of the input rectifier
To use the monitoring the +24 V power supply (X99A or X99B) must be available.
Following features are monitored: - Voltage failure
- Phase failure
- High temperature (overload)
y Mains monitoring BUM 62
This prevents an internal and external "ready for use" message if a phase is missing in the mains.
y Mains monitoring BUM 63 / 64
This prevents an internal and external "ready for use" message if a phase is missing in the mains voltage.
y
Phase monitoring BUM 62
The phase failure monitoring function recognizes that a phase is missing in the supply voltage and give
a warning message.
After 10 seconds the error is stored and an internal and external "ready for use" message is prevented.
y Phase monitoring BUM 63 / 64
This prevents an internal and external "ready for use" message.
y
Temperature monitoring
The temperature of the cooling element is monitored and a warning message is given in case of over-
load, i.e. excess temperature.
After 10 seconds the error is stored and an internal and external "ready for use" message is prevented.
NOTE
After switching on the +24V electronics supply, the operation of the mains monitoring is only saved
when:
- the mains is reported OK for the first time
- the DC link voltage has dropped below 300 V.
