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 chart on next page for DIP switch functionality.
In this example DIPs 1, 2, 5 and 12 are on.

Speed: Choose how quickly the actuator will turn the drive wheel. See pg.7-8.

Turns: The actuator usually ships from the factory with the recommended number of turns for the valve.
This number can be changed however. See pg.7for relation between position of the DIP switches vs.
number of turns.
Turning on a switch will add that number of turns to the actuator’s movement.
Example: Turning on DIP 6 will add 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.

Signal loss: See below.

11
Power: Set how much torque the actuator exerts on the valve lever. See below and pg.7-8.
12
Direction/Calibration: Toggle switch on and off while powered to re-calibrate actuator. Also sets direction in
which the actuator will open and close. See pg. 5-6.
Example: The MCM model actuator turns clockwise when the signal is decreased with DIP 12 in the OFF
position. For changes to rotation to take affect flip the switch and cycle the power to the actuator.
When cycling the power, the power must be off for at least 2 minutes to ensure the battery has switched off
