Section 16: C-TEST-MODE and TEST-RUN
C-TEST: During each switching operation in AUTO-MODE the power of the particular
capacitor stage is calculated and compared to the step power of the capacitor stage in the
background. An error message will be displayed in case of discrepancies!
A calculated faulty capacitor will be shown in the display as inverse capacitor-
symbol
1
C-TEST
[YES]
( YES/NO)
The C-TEST can be suppressed here.
[MMI8003]
[1]
(1...6)
[NO]
(NO / YES)
5
C-FAULT( + )
[140]%
(105...200%)
Here the upwards deviation from the capacitor's nominal value can be determined.
In case this value is reached, an error message is displayed.
6
C-FAULT (-)
[60]%
( 10...90 %)
Here the downwards deviation from the capacitor's nominal value can be
determined. In case this value is reached, an error message is displayed.
7
TEST ATTEMPTS
[6]
( 3...25)
A C-error message is displayed only after these given numbers of consecutive
measurements have indicated an error of the capacitor output.

FAULT C: OFF
8 FAULTY-C B LINKING
[NO]
(NO / YES)
YES: defective capacitor will indicate blinking as inverse capacitor symbol,
even when switched off.
9
TEST-RUN
[NO]
(NO / YES)
YES: starting of 3 Test-runs. Here all stages will switched-on and -off one by one.
The difference-current (before and after switching) are captured, rated and stored.
All values are transfered to the table in item 13.
