Code Cause / significance
F9 OSSD short circuit after VCC
output 2 or cross-circuit
F10* Undervoltage on power
supply
F20 Internal fault
F21 Internal fault
F22 Internal fault
F23 Internal fault
F24 Internal fault
F25* Different transmission
channels discovered (during
operation)
F26* Different evaluation proce-
dures (SCAN) discovered
(during operation)
F27 Internal fault
F28 Internal fault
F29 Internal fault
F30* Error in semiconductor test
(multifuse)
F32* RES operating mode
changed (during operation)
F33* EDM operating mode
changed (during operation)
F34* EDM timeout exceeded
(feedback circuit closes or
will not open)
F35* Start/restart button pressed
longer than 10 seconds
F36 Test identification signal from
transmitter longer than 3
seconds
F37* EDM configuration error
F38 Internal fault
* Locking error - a system reset is only achieved by switching the supply voltage off and on
again.
