Error messages
If the units monitoring system detects a fault during the execution of a function, a mes-
sage will be shown in the parameter display on the Control and display panel.
•
messages with the designation "ERR"
•
messages with the designation "CAL", and
•
messages with the designation "USE".
Messages with the designation "ERR" indicate an erroneous parameter - e.g. when toler-
ance limits are exceeded.
Messages with the designation "CAL" indicate a fault in the execution of a function or that
important necessary conditions for the correct execution of individual functions in certain
partial ranges no longer exist.
Messages with the designation "USE", while they indicate the incorrectness of a parame-
ter or of the execution of a function.
In any case, all three error types cause the:
•
interruption of the routine just performed,
•
several (10) beep tones generated by the buzzer on board D3 to signal this interruption,
•
switch-off of the green "ready" LED on the Control and display panel
•
if an error has occurred in the charging circuit for the capacitor bank, initiation of a
capacitor discharge procedure.
The normal function of the buttons on the Control and display panel is then disabled.
The error message can be acknowledged by pressing the selection button "kV+". If sev-
eral faults occur simultaneously, it may be necessary to press the selection buttons sev-
eral times to return to normal function.
The capacitor bank is then charged again.
When the kV - dependent final value of the capacitor potential is reached, the green
"ready" LED on the Control and display panel is also turned on again.
The unit is ready to operate.
Details concerning the meaning and elimination of error messages are given in the Ser-
vice Instructions!
