Valve Application
1.
Check entire motorized valve assembly to ensure that
the mechanical connections (among motor, linkage, and
valve) are proper and secure. Be certain that the linkage
is adjusted according to the linkage instructions. Leave
the linkage cover off until the checkout is completed.
2.
Be certain the load does not exceed the motor rating.
When using a Q5001 Linkage, no lubrication is
required. Install the plastic washer on the motor shaft
between the motor and cam to avoid motor binding and
stalling. Check to ensure that the linkage spring
compression is within the limits specified in the Q5001
Installation Instructions.
3.
Energize the motor by setting the controller so that its
contacts close.
NOTES:The motor should start and run smoothly,
moving the valve stem to the opposite end of
its stroke. If this is not the case:
—Ensure there is power to the motor.
—If there is not power, check the controller
circuit for open or short circuits.
—If the trouble still cannot be found, measure
the voltage at the source.
—Line voltage must be at least 85 percent of
rated voltage stamped on motor nameplate.
4.
De-energize motor by resetting the controller so its
contacts open, or remove one wire from a controller
terminal. Spring power should return the valve to normal
position. If this does not happen, check the linkage for
binding, or in the case of normally closed valves, check
for fluid pressure in excess of the close-off rating.
5.
Replace the linkage cover.
REPLACEMENT
Damper Application
1.
Turn off power and remove wiring from the old motor.
2.
Remove crank arm from the old motor shaft and remove
the old motor.
3.
Check to determine whether or not the mounting
bracket is needed. If the linkage can reach the new
motor lower shaft position and the crank arm has
clearance for the necessary rotation, then the bracket is
not required. Use the 220738A Adapter Bracket or the
221455A Crank Arm if the crank arm must rotate
through the motor bottom plane.
4.
If no bracket is required, mount the new motor directly
to the equipment and refer as necessary to Installation,
Settings and Adjustments, and Operation and Checkout
sections of these instructions.
5.
If the bracket is required, refer to the Adapter Bracket
section and see Fig. 3 in addition to the Installation,
Settings and Adjustments, and the Operation and
Checkout sections of these instructions.
6.
Use old mounting bolts to mount the new motor.
7.
Mount the damper crank arm and linkage to the shaft of
the new motor.
8.
Use the Checkout procedures to test proper adjustment
of the crank arm and linkage.
Valve Application
When replacing a motor in a valve application that has a
Q100, Q601 or Q618 Linkage, it will be necessary to use the
220738A Adapter Bracket provided to raise the motor shaft to
the same height as that of the old motor. In valve applications
that have a Q5001 Linkage, the 220738A Adapter Bracket is
unnecessary. Ensure motor stroke is 160° to operate
Honeywell V5011 Two-way or V5013 Three-way Valves.
