Replacement Kit (part no. 5112-11).
OPERATION AND CHECKOUT
Once both the mechanical and electrical installations are
complete:
1. Cycle the actuator to verify that the direction of rotation
suits the control sequence.
2. If the rotation direction is incorrect:
a. For 2-position spring return actuators: Remove, flip
over, and replace actuator on the bracket.
b. For floating control actuators: Reverse two control
signal wires (CW/CCW), or change position of
selector switch.
c. For analog control actuators either:
(3) Change setting of reverse/direct-acting switch, or
(4) Remount actuator on the bracket.
