9.3 Fault detection
The fault can be caused by mechanical or electrical malfunctions.
LED H4 The occurrence of an error state is signalized by the lighting up of the red LED H4 on the
front side of the housing of b maXX 4000 devices.
7-segment display Additionally the error code is shown via the 7-segment display on the front side of the
housing (not BM4XXX - XXX - XX0XX and BM4XXX - XXX - XX1XX).
By the displayed code the error message can be determined with help of ZError param-
eters, error messages, error reactions– from page 240. The displayed error is without ex-
ception an LEVEL 2 error (P0201 - P0216).
The display of an error code starts therewith, that „F“ is displayed for 1.5 s. Then the three
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: Error 125 and 91 are generated:

NOTE!
If warnings or errors occur without error reaction the LED H4 „error“ flashes. Only er-
ror messages with error reaction are displayed by constantly lighting up.
