Connection Options - gefran KFM LD Instruction Manual

2.5.1. Connection options

1. The control device is actuated via an interface with 24-V logic level at connections X2 / X3. The control
system is connected via two separate connecting lines.
2. The connection via CAN bus by means of a CAN bus line to connections X2 / X5 is based on a special
thyssenkrupp CAN bus specification and requires an elevator control unit from SIEI-AREG GmbH as pre-
requisite (Not implemented).
3. Connectors X2:5 and X3:4 can be occupied as input 1 and 2. The function is set via parameters ase1 and
ase 2. Pins X3:1-3 are only used as outputs. The function is defined via parameters aas1 – aas3.
4. The pin connector socket X4 light grid is used to connect an external light grid. At pin 1 + 24V and pin 3 / pin
4 GND, the supply of the light grid can be tapped. These pins are directly connected to connector X2. The
signal (24V logic) of the light curtain is routed to pin 2 which is internally connected to pin 4 of connector X3.
The function of the light curtain must be activated in the software via a parameter.
5. In the CAN connection X5, pins 1and 2 interconnected. The CAN signals are simultaneously on the connec-
tions X5 and X1.
Connection information, program updates and further details from the manufacturer are available from SIEI-AR-
EG GmbH.
