Troubleshooting
No Rotation or Wrong Stroke Range
NOTE: Pausing for up to two minutes is part of
normal operation. See Operation on page
3.
• Check that the shaft moves freely. (Press and
hold the gear disengagement lever and manually
rotate the shaft.)
• Check wiring. (See Wiring Issues section below.)
• Check for a tripped circuit breaker to the
transformer, for proper supply voltage from the
transformer (or power supply), and for enough
capacity (VA) for all connected devices. See their
respective data sheets and Tips for Connecting
24-Volt Power Application Note (AN0604D)
available on the KMC Controls web site.
• Check the adjustable stop position.
Wiring Issues
• Check for correct wiring at the each device.
• Use a voltmeter and ohmmeter to check the
terminals for expected values.
• See Tips for Connecting 24-Volt Power Applica-
tion Note (AN0604D).
NOTE: Wiring must be adequate to avoid
excessive voltage drop on long runs! Allow
plenty of “cushion” in measurements. A
meter may be too slow to register transient
dips or peaks during startup.
