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)
Operating mode
Fault display

Key to symbols
*
Latching fault; use corresponding output bit LM.ACK_G to reset
**
Non-latching fault; open guard and close it again to reset
*** Latching fault; use corresponding output bit LM.ACK_ER 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.
