16. System status table, module LEDs
All diagnostic messages are listed below. The scope of the possible messages may differ depending on the type and number
of modules/submodules used.
16.1. System indications if there are faults (module LEDs)
If there are faults, the bit
LM.E_G
is set. After the fault has been rectified, it can be acknowledged using the bit
LM.ACK_G
.
The bit
LM.E_G
is reset during this process. Exception: escape release fault (see
19.2. Fault on actuating the escape
release on page 38
)

to reset, door must be open during this process (see chapter
16. System status table, module LEDs on page 33
)
Important
: If you do not find the displayed device status in the System status table, this indicates an internal device fault. In this case, you should contact the manufacturer.
