Potentiometers are favourably priced, robust angle encoders for actuators. Several different versions are available to choose from:

• Conductive plastic potentiometers (standard) or wire-wound potentiometers (on request)
• Single-turn or multiturn potentiometers
• Single or tandem potentiometers
• Potentiometers approved for gas/air ratio control systems to DIN EN 12067-2:2004-06
• Custom potentiometers (resistance value, angle of rotation and so forth) on request

Depending on the actuator model and its configuration it is possible to fit up to three potentiometers.
To obtain highly accurate evaluation results the resolution of the maximum angle of rotation of rotary and part-turn actuators is set to the electrical angle of rotation of the potentiometer. Other resolutions are available on request.
The resolution of the maximum linear regulating distance of linear actuators is set to the electric angle of rotation of the potentiometer.

Absolute encoders using the Hall effect operate contact-free; consequently, they offer very high levels of reliability and a long service life. A variety of models are available on request.

With the aid of a service switch it is possible to operate the actuator no matter the status of the higher-level controls.

• Manual / automatic operation switch selection (toggle switch)
• Clockwise/anti-clockwise rotation (toggle switch)
• Integrated in actuator or operated externally

An anti-condensate heater can help prevent the build-up of condensate if the actuator is exposed to high levels of humidity and fluctuating ambient temperatures. The heater is also avilable as retrofit kit.

• For single-wire control
• To operate several actuators in parallel via a single control cable

Relays are available to implement customer- specific circuit arrangements; these are integrated in the actuator and wired to customer specifications (relays available as retrofit kit on request). As a rule, the coil voltage corresponds to the operating voltage of the motor.

To change direction of actuator operation, for example, by means of a control pulse

Relays are available to implement customer- specific circuit arrangements; these are integrated in the actuator and wired to customer specifications (relays available as retrofit kit on request). As a rule, the coil voltage corresponds to the operating voltage of the motor.

Agromatic has developed a fail-safe module that ensures the electrically powered actuators take up a safe end position if the power supply fails or is disrupted. The direction of rotation of the actuator to take up the safe end position is selected by means of a plug-in jumper. When the power supply is restored, the module switches back to normal operation.

Suitable for actuators powered by an operating voltage of 24 V DC, it is possible to integrate the module in an existing actuator circuit. Only the permanent power supply of 24 V DC is required in addition.

If the power supply fails, the fail-safe module switches to battery operation and moves the actuator to the safe end position selected. During normal operation, the module’s energy accumulator is moved by the supply voltage. The fail-safe module has been designed for mounting onto standard rail inside a control cabinet. It includes all the electronic components to carry out the function. Contact our Sales department for more detailed information.
