13. TROUBLESHOOTING
All SVS Lifts are quality checked before they leave the SVS Factory and are fully operational. Shipping
damage and installation oversights can cause problems to appear. Here are a few common and simple things to
check. If at anytime you are unsure of the check, please contact SVS, we will be happy to help you troubleshoot
your problem.
Symptom Possible Cause(s) Solution
Lift does not move Lift is not plugged into AC outlet or
AC outlet circuit breaker off. Make sure Lift is plugged in and
circuit breaker is turned on.
Is the Wall Plate Controller
connected to the Lift? Plug the Wall Plate Controller into
the Lift Gray Control Box 12-pin
Clinch-Jones connector.
Check the Lift Power fuse located
on the Lift Control Box If the fuse is blown see Blown Fuse
Symptom.
Lift power supply At the Wall Plate Controller
terminal strip measure the AC
voltage between the white and
black wires, the voltage should be
about 24VAC, if not contact SVS.
The Drum Lock Solenoid does not
energize when you press the toggle
switch down. Disconnect one of the solenoid
wires and measure the resistance
across the solenoid terminals. If the
resistance is less than 9.5 ohms
replace the solenoid.
The Drum Lock Arm does not raise
when the Drum Lock Solenoid
energizes. Check the Drum Lock Linkage
between the Drum Lock Solenoid
and Drum Lock Arm. If the Linkage
is disconnected, reconnect. If
broken, replace it.
Drum Lock microswitch damaged. Check Drum Lock microswitch.
Blown Fuse Power Transformer Shorted Unplug the lift, replace the fuse,
and measure across the two flat
prongs of the AC plug. If the
resistance is less than about 19-22
ohms, replace the transformer.
Drum Lock Solenoid Disconnect one of the solenoid
wires and measure the resistance
across the black and green wire. If
the resistance is less than 9.5 ohms
replace the solenoid.
Lift does not lower but will rise Down Limit microswitches or
associated wiring damaged Look for damage. Check for
continuity from the Wallplate
Controller to the Down Limit
