Electrical Installation - DynaQuip MA Serie Manual De Instalación Mantenimiento Y Operación

Please read and save these instructions. Read carefully before attempting to assemble, install, operate or
maintain the product described. Protect yourself and others by observing all safety information. Failure to comply
with instructions could result in personal injury and/or property damage! Retain instructions for future reference.
Installation
1. Before mounting the actuator, verify that the valve
torque requirement is less than the rated output
torque of the actuator.
2. Check that the output shaft adapter fits the stem of
valve or damper before inserting into the actuator.
3. Insert the output shaft adapter into the actuator.
Make sure fit is satisfactory.
4. Determine that actuator position, open or closed,
matches position of equipment with which it is to
be mounted. Use manual override to change
position, if necessary.
5. Mount to top plate of valve, valve bracket or damper.
Be sure that base of actuator is flush with top plate.
6. Insert bolts but do not tighten.
7. Use manual override to move stem of valve or
damper slightly to correct side thrust or misalignment.
8. Manually place valve in either full stroke position.
9. Tighten bolts using a cross pattern and equally
drawing bolts down to finish.

Electrical Installation

Verify that the electrical supply voltage is the same
as the required actuator voltage.
NOTE: Electric power to terminals 1 and 3 will cause
the camshaft to rotate counterclockwise.
Electric power to terminals 1 and 4 will cause the
camshaft to rotate clockwise.
See electric schematic.
Travel Stop Adjustment
At the base of the DynaQuip Controls MA series electric
are two (2) adjustable travel stops.
1. Facing the actuator, with housing vertical, the
adjustable bolt to the left controls CCW movement
(valve open). The bolt to the right controls CW
movement (valve close).
2. Loosen both adjustable stops so that full travel in
either direction will not engage them.
3. After mounting and tightening actuator to valve, use
manual override to drive valve to fully closed position.
4. Tighten the adjustable stop bolt on the right side until
it engages the stop. Back the bolt off one-half turn.
Tighten nut.
5. Follow same procedure in item 4 after fully opening
the valve.

Cam Adjustment
The cams are preset at the factory. When additional
adjustments are needed, follow steps below.
SETTING OPEN POSITION
1. Turn power off.
2. Use manual override to turn valve to the fully
open position.
3. With the power turned off, remove cover, loosen
set screw in the bottom cam. This cam controls
the open position.
4. Rotate cam clockwise into the switch.
5. Slowly rotate cam counterclockwise until you
hear a light click. Tighten set screw.
6. Reinstall cover and turn power back on.
SETTING CLOSE POSITION
1. Turn power off.
2. Use manual override to turn valve to the fully
closed position.
3. With the power turned off, remove cover, loosen
set screw in the second from bottom cam.
This cam controls the closed position.
4. Rotate cam counterclockwise into the switch.
5. Slowly rotate cam clockwise until you hear a light
click. Tighten set screw.
6. Reinstall cover and turn power back on.
Maintenance
Under normal operation, electric actuators require
no formal maintenance program. Regularly scheduled
inspections should be performed to check for:
• Actuator-to-valve misalignment
• Damaged housing or mounting hardware
• Worn, loose or shifted parts due to shock,
vibration, etc.
