10.3 Fault detection
The fault can be caused by mechanical or electrical malfunctions.
LED The occurrence of an error state is signalized by the lighting up of the red LED H14 on
the front side of the housing.
The meaning of the individual LEDs is explained in ZLED display controller– on page
130.
Essentially, the lowest red LEDs H14 „Malfunction“ are of significance here.
7-segment display In the status error the error numbers are shown in the display. Depending on the state of
bit No. 16 in parameter P135.1 (further information refer to parameter handbook b maXX
BM5000) all error messages (with/without error reaction) or warnings are displayed.
The display of an error code starts therewith, that „F“ is displayed for 1.5 s. Then the four
characters of the error code are displayed. The separate characters are displayed for
about 0.8 s, interrupted by a short break. If there are other errors, these are displayed in
the same manner. The procedure is repeated as soon as all errors were displayed.
Example: Errors 702 and 2418 are detected:

rameter manual b maXX 5000".
NOTE!
In case of warnings or errors without error reactions, the LEDs H14 blink „Malfunc-
tion“. Only error messages with error reaction will be signalized by constant lighting
up.
