Use an insulated screwdriver to actuate the switching rolls of the DE switches and WE switches as shown in the 

connection diagram and check that the respective switches actually switch off the motor. 

If necessary, change the motor supply jumpers installed.

  

 

Risk of electric shock!

6. ACCESSORIES

 

 

 

When mounting, always make sure that the connecting rod is extended.

 

 

 

Disconnect the actuator from power before starting any work!

 

 

 

 Attention: limit switches can only be installed when mounted "with a potentiometer" 

(main board)! 

6.1 Switching and signalling unit

This actuator can be equipped with a switching and signalling unit 

[114]

This unit includes:

 

●  2 travel-dependent switches "WE"– S3 and S4 

[282]

 which can be used as limit switches or signal switches 

(as special version also available with 4 WE)

 

● 1 potentiometer

 [283] 

as signalling module
