Alarm 47:
During the start up there is an input contactor test. If this test ends unsuccessfully
the rectifier will be blocked.
Alarm 48:
If the output voltage ramp doesn’t work properly during the inverter start up the
inverter will be blocked (See alarm 67).
Alarm 49:
This alarm appears when there is an offset voltage higher than 8 V, in any phase of
the inverter output voltage phase to neutral. Then the inverter will be blocked.
Alarm 50:
This alarm appears when the UPS is blocked for any reason. This condition blocks
also the inverter.
Alarm 51:
If the inverter protective circuit to prevent overload IGBT inverter has been
activated, this message appears. The inverter is now blocked.
Alarm 52:
There is a command from the microprocessor to the DSP, with no response from
the inverter module of the DSP. The inverter will block.
Alarm 53:
After 5 times shutting down the inverter because of (*) DSP Internal Error in the
inverter module, this alarm will appear indicating inverter blocked.
Alarm 54:
This message appears when a blockage of the rectifier and the UPS has occurred.
Alarm 55:
The alarm appears when the DSP doesn’t response to the microprocessor during
the initial procedure before the start up.
Alarm 56:
There is a command from the microprocessor to the DSP, with no response from
the UPS module of DSP. The UPS will block.
Alarm 57:
This message appears when a blockage of the inverter and the UPS has occurred.
