Description of operation

This actuator is used to operate 2- and 3-way valves in ventilation and air conditioning units and must

only be used for these purposes. Use outside of HVAC installations is only permitted after consulta

tion with the manufacturer.

Depending on the type of connection (see connection diagram), the actuator can be used as a contin

uous (0…10 V or 4…20 mA), 2-point (OPEN/CLOSE) or a 3-point actuator (OPEN/STOP/CLOSE).

The running time of the actuator can be set with switch S1 according to the respective requirements.

Switch S2 can be used to change the direction of operation.

In the end positions (valve limit stop or when the maximum stroke is reached) or upon overload, the

electronic motor cut-off (no limit switch) responds and turns off the motor.

The external crank handle enables manual positional setting. After the crank handle is folded back,

the actuator moves to the target position again (without initialisation). When the crank handle is folded

out, the actuator remains in this position.
