On/off is avaliable in two different variants
1. The basic version with electromechanical circuit breaker. A feedback signal (4-20mA) is possible with accessories POT and TAM.
2. With LCD display and push buttons, this includes control with either 4-20 mA or 0-10 V.
For regulatory
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.
See the manual for start-up, storage and maintenance.
