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 control actuators: Remount actuator
on the bracket.
b. For floating control actuators: Reverse two control
signal wires (CW/CCW).
c. For analog control actuators either:
(1) Reposition reverse/direct acting switch, or
(2) Remount actuator on the bracket.
3. If the control scheme requires fail-safe operation, ensure
that, upon removal of power, the fail position coincides
with the control sequence.
