CAN
communication
indicators
These indicators indicate the CAN
communication status of elevators 1 to 8.
Flashing: Indicating that the elevator is in the
automatic running state, with normal CAN
communication.
Steady ON: Indicating that the elevator is not
in the automatic running state, but the CAN
communication is normal.
Steady OFF: Indicating that CAN
communication of the elevator is
interrupted.

24 V power
indicator
This indicator becomes ON after the GCB is
powered up.

D94
Fault indicator
This indicator becomes ON if an elevator
runs out of the group control or there is a
communication error.

NOTE
◆
To prevent external communication interference, use the shielded twisted
pair (STP) as communication cables and avoid laying them in parallel.
◆
The GCB must be powered by an independent 24 V power supply, and
cannot share the 24 V power supply with the elevator system.
