5.2 Properties of CAN BUS Systems
- The CAN BUS is a 4-wire bus, comprising + 24 V, GND and 2 data cables (CAN-L and CAN-H).
- Because the connectors on the CAN BUS cables are very small, a housing is sometimes mounted on the connectors to make it easier to connect in hard-to-reach places.
- The CAN BUS components are automatically detected by the control unit.
- The function (combined function/safety secondary closing edge) and position (inside/outside) of the sensors must be set (see DIP switches 1-4).
- If a CAN BUS component is replaced or removed from the network, a CAN BUS reset must be carried out.
5.2.1 CAN BUS Y-adapter
- A CAN BUS Y-adapter is used to install branches in a CAN BUS system.
- Only 1 CAN BUS component may be connected to a branch.
- Up to 5 branches may be installed in a CAN BUS system.
- The cable length on a branch may be no more than 10 m.
5.2.2 ST PRO Multi-point Locking System
The ST PRO multi-point locking system interrupts the CAN BUS connection during operation. Therefore, the ST PRO multi-point locking system must be connected to the CAN BUS system using a CAN BUS Y-adapter.
The extension cable may not be used for the ST PRO multi-point locking system!
5.2.3 Terminating Resistors
- A CAN BUS system always requires 2 terminating resistors.
- The 2 CAN BUS components furthest away from the control unit, measured by cable length, are fitted with the terminating resistors.
- The CAN BUS components either have a switchable terminating resistor (DIP switch 5 on the sensors) or the terminating resistors are connected to the free CAN BUS connection.
- The total length of the cables between the two terminating resistors must not exceed 30 m.
5.2.4 DIP Switches on the Sensors
For escape route sliding doors, a combination detector must always be connected to the inside of the MCE with the DIP switch position MCE inside 1!
The various addresses (function/position) are set on the DIP switches 1-4. The terminating resistor is activated on DIP switch 5.
Configuration Settings
Note: Refer to original documentation diagrams for exact DIP switch positions (ON/OFF) for each setting.
5.3 Structure of a CAN BUS System
The CAN BUS components must not be connected under live voltage!
- Remove the terminating resistor from the required CAN BUS connections on the operator control unit and retain.
- Connect the CAN BUS components in any order to the CAN BUS cables.
- Drill the holes for carrying out the CAN BUS cable with Ø 8 mm and then deburr.
- Clean the operator profile and running profile.
- In both CAN BUS components furthest away from the control unit, measured by cable length, connect 1 terminating resistor or activate the switchable terminating resistor (sensors).
5.3.1 Schematic Examples of Wiring
Note: The terminating resistor is permanently installed in the multipoint locking system.
