Automax Valve Automation Systems
Installation, Operation and Maintenance Instructions
Introduction
The Centura CPL Series electric actuator is a rotary valve
actuator with output torques of 100 and 225 in-lbs. It has
been designed for NEMA 4, 4X and can come with an
externally mounted 20mA card for modulating service.
Storage
1. Keep conduit entries plugged.
2. Store in a dry environment.
3. Periodically cycle the actuator if possible.
Maintenance
Centura Series actuators contain a permanently lubricated,
precision cut, heat treated gear train for long, reliable cycle
life. There is no need to change gear train grease.
Permanent split capacitor gearmotors have been
equipped with thermal protectors. After many operations
especially in warm environments the motor will heat up. To
guard the motor against overheating the thermal protector
opens the circuit to the motor and maintains this state until
the temperature of the motor drops to a satisfactory level.
This thermal protection means that the actuator will not
move when overheated. Consideration must be given to the
duty cycle requirements of the actuator.
Installation
1. This section of the instruction sheet applies to the on-
off units. For instructions on modulating units, please
see the ESP3 Electronic Servo Positioner Instructions.
2. Manually open and close valve to ensure freeness of
operation.
3. Be sure valve and Automax actuator rotate in the same
direction and are in the same position (i.e., valve closed,
actuator closed). If not sure, electrically operate the
actuator to determine its operating range. The electric
actuators are factory set for 90 degree operation.
4. Mount Automax actuator to valve with Automax
provided mounting hardware to assure proper
alignment. (
NOTE: Some valves have manual stops;
remove if appropriate or set actuator to operate within
those travel stops.)
Installation Instructions
5. Care should be taken to properly align valve stem and
Automax actuator output shaft (misalignment will cause
premature failure of assembly).
6. To connect power to terminal strip of actuator it is
necessary to remove the cover.
7. After cover has been removed, locate the terminal
wiring schematic inside the cover.
8. Connect power to terminal strip according to schematic
diagram (power should be fused with a 5 amp slow-
blow fuse). The actuator should be wired and grounded
in accordance with Local and National Electrical Codes.
Caution: Consult factory when wiring multiple actuators
in series or parallel, serious damage may result. User
must isolate unused winding.
9. Before replacing cover, actuate valve and check to see
if it opens and closes to preferred positions. If valve
does not perform correctly, adjust cams to properly set
actuator travel.
10. Drive actuator to desired open position. The cams are
adjusted in two ways. Simply depress the splined
“Quick-Set” cam against the spring and rotate to
desired location.
11. To adjust closed position, repeat step 10 with actuator
in desired closed position.
12. Operate the unit several times and recheck position.
If unit is still out of adjustment, reset the cams by
following steps 10 and 11.
13. 60Hz actuator motors may be run on 50Hz supply,
however, the cycle time increases by 1.2 times and the
duty cycle decreases by a factor approx. 25%. The
rated torque does not change.
Position Indication Stickers:
A ttached to the inside of the cover is a set of stickers with
the words "CLOSED" and "OPEN." These stickers are to be
attached to the outside of the actuator base. The stickers
have an orange triangle on them, such that when properly
attached, the actuator will line up with the triangle on the
output shaft. A sticker can be placed on either side of the
unit to produce a visual indication of the opened and
closed position of the actuator.
Caution: To prevent electrical shock keep unit tight
while circuits are alive. Disconnect supply circuit
before opening.
