Use a door control that complies with the EN ISO 60335-1.

Attaching the connection cables

• Remove the limit switch cover.
• Plug in the motor connector.
• Connect the limit switch plug.

Mechanical limit switch – function

Cams S1 – S6
Use cams S3 and S4 to specify the final limit positions OPEN and CLOSE of the door.
The cams S1/S3 and S2/S4 are mechanically linked. The emergency limit switches S1 and S2 only switch when the drive unit moves beyond the final limit positions OPEN and CLOSE. The emergency limit switches are automatically preset with the final limit positions. An actuated emergency limit switch interrupts the safety circuit. The drive unit switches off.
You can use the auxiliary limit switches S5 and S6 individually through terminals X12.11-13 and X12.14-16 (see the circuit diagram of cam limit switches).

Terminals 4 to 9: safety circuit
Terminals 4 and 9 form the safety circuit. If the safety circuit is interrupted, the drive unit switches off. Terminals 21 to 26 are factory- fitted with wire links. Instead of the wire links, you can connect additional safety devices (e.g. safety brake). Terminals 27 and 28 are used for the thermal protection of the motor.

Mechanical limit switch – setting the final limit position

The following explains how to set the limit switch and thereby specify the final limit positions OPEN and CLOSE.

Check the output rotating direction

• Issue an OPEN command.
• If the door opens, the output rotating direction is correct. Continue with setting the final limit position OPEN.
• If the door closes, the output rotating direction is wrong. Change the output rotating direction before setting the final limit positions.

Setting the output rotating direction
If the movement direction of the drive unit does not correspond to the movement command, you can change the rotating direction. If you use a GfA door control, change the output rotating direction by using the programming. Follow the instructions for the door control. Otherwise change the output rotating direction as explained below.

WARNING Danger to life from electric shock!

Improper wiring may result in severe or fatal injury from electrical current.
Disconnect all cables from the power supply.

• Disconnect all cables from the power supply.
• Swap L1 and L2 in the supply line.
• Then switch the voltage back on.

Setting the final limit position OPEN

• Remove the limit switch cover of the drive unit.
• Issue an OPEN command until the door has reached the desired position.
• Turn cam S3 to the centre of the switch. ****
• Tighten the screw for coarse adjustment with the enclosed key.
• Check the set position by closing the door until the cam no longer touches the switch. Then move to final limit position OPEN.
• The final limit position OPEN can be corrected by fine adjustment.
• Check the door position after a correction.

Checking and correcting the emergency limit switch OPEN
Setting S3 will automatically preset the emergency limit switch S1. Check whether the preset distance is sufficient. 

WARNING
Danger from falling objects!

If a limit switch does not switch, the drive unit is stopped by the emergency limit switch. If the emergency limit switch switches too late, the door can be damaged or parts of the door leaf may come loose.

• Set the emergency limit switch.
• A fixed stop of the door leaf may reduce the danger.

Turn the screw for fine adjustment on cam S1 until the door stops without risk even when passing the final limit positions.

Setting the final limit position CLOSE and auxiliary limit switch
Proceed as for setting the final limit position OPEN.
