4.7 Setting Potentiometer (Optional)
The potentiometer has been calibrated at the factory. However, if re-calibration is required, proceed as
follows:
• Manually rotate the hand wheel of the actuator to the fully closed position.
• While measuring the resistance between P1 (black) and P2 (blue), gently rotate the
Potentiometer Gear until it reaches between 80 - 120 Ω (100 Ω preferred), by using a flat head
screw driver.
• Engage the Potentiometer Gear into the Point Shaft Gear and use an Allen key to fasten the
locking bolt of the Potentiometer Gear.
4.8 Current Position Transmitter – CPT (Optional)
The potentiometer is used for the actuator signal fe
