Standard version
Reversible actuator in four different sizes for 0-90° movement, adjustable through a combination of cams, mechanical end stop and/or torque switches.
The actuator is a compact combination of an electric motor with thermal protection and a self-locking worm gear. As standard with a hand wheel and position indicator.
The actuator mounting dimensions in relation to the fittings are according to ISO 5211.
Design lifetime 20 000 cycles for On/Off or 300 000 starts for positioning. Tested according to EN 15714-2 class A and B

During all work with the actuator the power MUST be disconnected.
- The actuator must be connected as per the wiring diagram, see the manual.
- Each actuator must be powered by an individual switch or relay contact, minimum 16A,to prevent cross-feed between the actuators.
- At outdoor installation, the actuator should be protected by a roof or cap.
- Installation with the motor downwards should be avoided.
- Turn the valve with the control unit's hand wheel to centre position. See indication on top of the device.
- Always connect the heater.
- Check that the actuator turns the valve in the desired direction.
- The correct limit switch (open or closed) shall break the motor current.
- Cable entries must comply at least to the lowest protection class of devices.
