SVS TL1 110V - Manual (Page 15)

14. 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 Arm is down and
laying on the Cable Drum.
Note: The Drum Lock Arm being
down will cause the Drum Lock
microswitch to disable the Lift
motor.
Check the Drum Lock Spring is
broken or disconnected. If the
Spring is disconnected, reconnect.
If broken, replace it.
The Drum Lock Pawl on the Cable
Drum should move freely and drop
when when it reaches the top of the
Cable Drum's rotation, avoiding
contact with the Drum Lock arm. If
the drum rotates too fast, the pawl
will swing out and catch the arm,
locking the drum after the first
rotation. Loosen the Drum Lock Pawl so that
it moves freely.
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.
