TROUBLEShOOTING
A.
n o valve movement:
1. Check that operating power and signal are present at the motor terminals.
2. Check fuse for continuity. Shut the isolation valves and then press the Reset push button. Observe that the valve travels
fully open then shut.
3. Review WIRINg AND STARTINg (pages 6-9) to confirm wiring and switch positioning.
4. Remember to press the Reset pushbutton to perform the AutoStroke calibration cycle. It will optimize performance and
maximize motor life.
B.
Valve and Motor are “out of sync” ie: the linkage or motor do not both reach their ends of
travel, or they arrive at different times.
1. Check for indication of slippage between the motor output clamp and the linkage input shaft. If slipping is detected, the
linkage and motor must be re-calibrated. See pages 11-15 as necessary to review both procedures. Pay close attention to
tightening the two 10 mm hex nut on the motor output clamp, and remember to press the Reset pushbutton to perform
the Autostroke calibration cycle. It will optimize performance and maximize motor life.
C.
After extensive usage, valve closure tightness appears to have diminished.
1.Remove the motor (see page 11) and then perform LINkAgE CALIBRATION (see pages 12-15) and MOTOR CALIBRATION
(see page 11). This will restore seat-closing force to its original high value, correcting for normal linkage wear.
2. Remember to press the Reset pushbutton to perform the Autostroke calibration cycle. It will optimize performance and
maximize motor life.
