VERRIDE
To use the manual override, push the override shaft down approximately a 1/4-inch to disengage the motor from
the gear train. While holding the shaft down, turn the shaft with a wrench to reach the desired position. NOTE:
The rotation of the output may not be the same as the rotation of the override shaft! Note which way the output
rotates whenever you use the override shaft. Also, be careful not to drive the actuator past the limit switch
settings; it is possible to damage installed options such as a feedback potentiometer.
The manual override shaft must be returned to its fully upward position before the motor is re-engaged. If it does
not "spring" back up into the correct position, rotate it slightly to align the spur gears and it should spring back up.

ROUBLESHOOTING
If the actuator fails to operate:
Visually inspect for damage, burn marks, or loose connections.
Check that the proper voltages are present at the actuator's terminal connections.
Check all the plug-in connections to be sure they are properly installed - Motor to connector S3
Bottom limit switch to S2
Second limit switch to S1
Motor capacitor to J & K
If the motor is hot, the actuator may have gone into thermal overload protection. Let the motor cool and try again.
Ensure the limit switches are properly set.
Ensure the actuator's duty cycle is correct for the application.
Ensure the actuator's output torque is within the required range.
If the actuator's motor hums or turns slowly, check the actuator's motor capacitor to see if it is broken, cracked or
burned.
Make sure power is applied only to one terminal (either 3 or 4 but not both).
Check for a proper connection at motor socket S3.
Ensure you do not have more than one actuator wired in parallel.
If the motor turns but the output does not, ensure the manual override has returned to its fully upward position.

ARRANTY
P
OLICY
Valvcon products are manufactured with a two-year standard warranty. The warranty period begins with the date
of shipment from Valvcon, unless the end-user can show proof of an actual “start-up” date, in which case the
warranty period begins on that “start-up” date.
Your Valvcon Stocking Representative provides the first level of troubleshooting. The warranty is a "return to
factory" warranty, and it covers defects in materials and workmanship.
If your Stocking Representative cannot
diagnose and/or resolve the problem, they will return the unit to the factory for repair.
In the event of any questions or concerns, please contact your local Valvcon Stocking Representative. To
