Program 1
• After the start of the service program, "CAP 150" is shown on the display.
• The voltage rises incrementally from 150 V to 440 V DC. Each program step is per-
formed for approx. 6 minutes.
• The system maintains the voltage level of 440 V DC for approx. 1 hour. The program
is then ended automatically. After termination of the program, the message "CAP
END“ is displayed.
NOTE:
If the actual voltage is greater than 150 V, the program first performs a discharge to <
150 V. This process takes 10 to 15 minutes. The program then begins charging the
capacitor bank.
Program 2
• Display of exposure number in the display
NOTE:
It is not possible to reset to zero in the event of a tube change.
The counter reading must be noted as the starting value for a new component (e.g. sin-
gle tank).
