The door drive comes with 6 cam end switches as standard. All cams have 12 lock-in positions for quick adjustment. Check
that the control unit is in dead-man mode.
Proceed as follows to set the limit switch:
1. Turn all 6 cams out of the movement range of the door.
2. Use the “DOWN” button of the control unit to move the door to just before the lower limit position.
3. Turn the black cam S6 “CLOSE” until the precision set screw is within easy reach. Now use the ne precision set screw
(athead) to manually set the cam so that it switches. Move the door slightly up and down again until the end switch stops
the door. If necessary correct the setting.
4. Now move the door to just before the upper limit position.
5. Now set the grey cam S5 “OPEN” as for point 3.
6. Now set the yellow safety cams S1F “UP” and S2F “DOWN” to lag both operational limit switches S5 “OPEN” and S6
“CLOSE”.
7. The two functional cams S7 (orange) and S8 (green) can be set accordingly if required.
8. The limit switches are now set. Carry out a test run to check the set limit positions.
Note

The drives are equipped with an absolute value encoder with which the control unit recognises the door’s limit positions.
Attention
The absolute value encoder cannot be set in the drive.
The door limit positions are set directly in the control unit. Follow the Assembly and Operating Instructions for the control unit.
