Thrust actuator ARI-PREMIO
5.5.4.2 Setting the potentiometer
To set the potentiometer, proceed as follows:
- Move thrust actuator to extended position.
- Switch-off mains voltage and safeguard to prevent it from being switched back on again
accidentally.
- Turn potentiometer shaft in counter-clockwise direction until reaching the travel stop.
This places the potentiometer in the initial position (approx. 0 ohm).
- For checking purposes, the resistance of the potentiometer needs to be measured using
an ohmmeter.
- Measure resistance on potentiometer 1 between terminals 25 and 26.
- Measure resistance on potentiometer 2 between terminals 28 and 29.
- In this position of the actuator, the measured value should be approx. 0 ohm.
- Run thrust actuator to upper final position and read off corresponding resistance value on
ohmmeter.
- The resistance values thus measured need to be taken into account for the settings to the
facility control system.
