OPERATION
DIP Switches
The DIP switches allow you to change the
settings on your actuator. To flip a switch,
gently use a small flat-head screwdriver.
See table below for DIP switch functionality.

Speed:
Choose how quickly the actuator will turn the valve. See p.8.

Only in the ON position for actuator model RCH (with external gear stage).

Turns:
The actuator usually ships from the factory with the recommended number of turns for the
valve. However, this number can be changed. Turning on a switch will add a specific number of
turns to the actuator’s movement.
See p.8 for relation between positions of the DIP switches and number of turns.
Example: Turning on DIP 6 adds four turns, turning on DIP 8 adds one turn. If both DIP 6 and 8 are
on, then the total turns of the actuator would be five.
9
Signal loss:
See p.10.
10
11
Seating torque:
Set how much torque the actuator exerts on the valve lever during the calibration
(finding valve seat) procedure. See p.8.
12
Direction/Calibration:
Toggle switch on and off while powered to re-calibrate actuator (find valve
seat). Also sets direction in which the actuator will open and close. See p.10.
Example: The RCM model actuator turns clockwise when the signal is decreased with DIP 12 in the
OFF position. Putting DIP 12 in the ON position will cause counter-clockwise turning for a decrease
in signal. For changes in DIP 12 position to take effect, the power to the actuator must be cycled.
In this example DIPs 1, 2, 5 and 12 are on.
