Can Bus Connection (Not Implemented In Kfm Ld) - gefran KFM LD Instruction Manual

4.3.3. CAN bus connection (Not implemented in KFM LD)

(Operation is only permissible with a control from SIEI-AREG GmbH.)
If the KFM LD door drive is to be operated via the CAN-nodes, observe the following:
• An elevator control with matching software must be present.
• The TO, TU and TUL hardware trigger signals must not be connected.
• The TSO and TSU hardware acknowledge signals must no longer be connected, as the signals are output
via the CAN bus. They are, however, still available as a general principle.
• The connection for the approval inspection and the 24V DC / 0V of the elevator control must be connected.
Via jumper J3, the CAN bus can be terminated on the control electronics with 120 Ω. (Jumper closed → Bus
terminated with 120 Ω). The jumper must be closed if the KFM LD door drive forms the last node on the bus
and the bus is not connected to any other subassembly. In all other cases, the jumper must be open.
For operation via the CAN interface, the following must be provided by the elevator control:
+24V DC (power supply- CAN interface)
0V (power supply - CAN interface)
Approval inspection
CAN-H / CAN-L
The following are transferred via the CAN interface:
From elevator control system to door drive: Trigger signals: TO, TU, TUL
From door drive to elevator control system: Acknowledge signals: TSU, TSO, error and warning messages.
The CAN interface is isolated.
CAN bus connection for controls, with connections.
