Installation and Operating Instructions
Instructions de montage et de service
Setting additional limit switches E3/ E4
The additional limit switches E3 and E4 can be used to indicate any intermediate positions.
They can be adjusted by using adjustment spindles E3 and E4 (Fig.2). Electrical connection: (see wiring diagram REact3610E....NRTL)
Optional equipment
Feedback potentiometer1/ 2
see Fig.4 and Fig5
Potentiometer adjustment
In the case of delivery of an actuator with valve, the potentiometer is already factory adjusted.
(start value: approx 10% of the max. ohm value of the potentiometer)
Subsequent adjustment of the potentiometer:
•
Move the actuator to the desired end position.
•
The resistance of the potentiometer can be optionally adjusted by loosening the limit stop (Fig.5/ 3).
REtrans4W or REtrans2W
Fig. 9→see separate operating instructions REtrans-8010.
Heater
The fastening of the heater is shown in Fig.6.
The heater must be powered up permanently.
Electrical connection: (see wiring diagram REact3610E....NRTL)
Replacement of components

•
Remove the switch unit from motor plate.
•
Remove the lever from the-force switch (Fig.16, pos. 900).
•
Remove the terminal board (Fig.16, pos. 600) from switch unit.
•
Install the new terminal board.
•
Install the lever(force-switch) (Fig.16, pos. 900) onto the pin of the switch unit.
•
Secure the lever-with a quick look washer.
•
Install the switch unit on the motor plate.
•
Install the switching carrier unit
•
Perform electrical connection according the wiring diagram.
Maintenance, repair
•
The actuator is maintenance-free.
•
The actuator may only be cleaned with a mild soapy solution.
•
Lubricant for gear and spindle nut: see technical data in the appendix
Notes
The use of this actuator is for a specific purpose
The drive may only be used for the intended purpose. Control and shut off drive for control and Shut/Off valves.
External metal surfaces can get hot during operation. Do not touch.
