← Actuator scale: Clockwise
Adjustment range for switches A and B:
Setting interval: 5°
Switching hysteresis: 2°
← Actuator Scale: counterclockwise
To change the settings of A and B:
NOTE: The scale is only valid when the
actuator is in the "0" position on
clockwise motion.
• Use the adjustment tool provided
with the actuator to turn the
switch adjustment dials to the
