Error messages
Other error messages that may be displayed:
B900 CC supply voltage
5-V power supply too high
5-V power supply too low
C030 Alarm with supply voltages CC
C031 Alarm with supply voltages
C038 Voltages monitor CC
If the voltage at X69 and X74 drops during machine operation, the following error messages may
be issued:
8 Try to delete all error messages with the CE key. --> The permanent errors will remain in the ERR list.
If the supply voltage at X69 and X74 is already missing during startup, the CC 61xx is not found in
the HSCI bus system.
The message Hardware/firmware change detected is displayed.
--> See ”Message Hardware/firmware change detected” on page 18 – 245.
The most important voltage for powering the electronics is the 5 V supply voltage. The control
monitors these 5 V and generates an error message (e.g. CC +5V out of tolerance), if the
deviation becomes too large.
