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 actu-
ator 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 posi-
tion coincides with the control sequence.
4. If the fail safe position is incorrect, remove and
reinstall the actuator in the opposite orientation as
follows:
a. Loosen the shaft coupling bolt using a 10 mm
wrench.
b. Loosen all other mounting bolts connecting the
actuator to the mounting bracket, and set
aside.
c. Remove the actuator from the valve shaft.
d. Move the actuator coupling to the opposite side
of the actuator, as displayed in Figure 20.
Fig. 20. Mounting shaft coupling to actuator
opposite side.
(1) Remove the retainer clip from the shaft cou-
pling and set it aside for later use.
(2) Remove shaft coupling from one side of the
actuator.
(3) Replace the shaft coupling on the opposite
side of the actuator, aligning it based on the
stroke labelling.
(4) Replace the retainer clip on the shaft cou-
pling using the groove of the coupling.
e. Reconnect the actuator to the valve mounting
bracket by replacing the screws previously
removed (step b)
f. Tighten the shaft coupling bolt using a 10 mm
wrench.
