VSD TROUBLE SHOOTING GUIDE
DIAGNOSTICS FOR 24 VOLT VSD POWER UNIT
If the lift should raise or lower by itself without
operating the remote control, disconnect
the battery cable ring connectors from the
battery posts immediately, if you are able
to do so without the risk of injury. Contact
your local dealer or FLOE International, Inc.
WARNING
Never attempt to remove the brake
mechanism with the boat on the lift. If the
brake was loosened, the boat’s weight would
cause the cradle of the lift to lower rapidly,
causing potential serious injury or death.
WARNING
Always remove the boat and lower the lift
bed completely before attempting any work.
WARNING
Before removing the power unit, the cradle
lift beams must be completely lowered until
there is slack in the main lifting cables.
Failure to do so will cause the boat and
lift cradle to suddenly crash downward.
WARNING
A. Lift won’t go up or down
1. Check to see if the key on the wired remote is turned to
the ON position.
2. Check battery(s) condition and that it is properly charged.
Each battery should have between 12.7 and 13.8 volts.
3. Check to see that all battery connections are corrosion
free, tight, and wired properly. (See Fig. 7 on page 10)
4. Check plug connections from the Advanced Switch
Control (ASC) going to limit switch and remote(s) to ensure
they are plugged in properly and making positive contact.
5. Check the wire connections from the Advanced Switch
Control (ASC) to the motor to ensure they are corrosion
free and making positive contact. Connections are located
under the motor cover.
6. Check auto reset circuit breaker or fuse. If the breaker
has tripped, it should reset after a couple of minutes when it
cools down. If not sure it is working, you can bypass it.
- If circuit breaker has tripped or fuse is blown, chances are
the motor is drawing too much current and it could blow
the fuse or trip the breaker again. Check the following:
a. Is the lift overloaded or has it exceeded its max
run/cycle on time
b. Is the brake improperly engaged
• With VSD drive units, if the brake is not releasing
while in operation it will drag and cause the drive to
draw excessive current. You should hear the brake
“click” on the outside end of the VSD power unit
box when raising or lowering the lift.
c. Additionally there may be something causing
friction in the system, such as a problem in the
drive train, or the cable/pulley system has an issue.
B. Lift will only work in one direction
If this occurs, you may have a problem with the end of trav-
el limit switch(es).
1. Test the end of travel limit switch(es) by using the limit
switch bypass plug located in the tool pouch.
2. To do this, unplug the limit switch plug going into the
ASC and replace it with the bypass plug.
3. If the cradle is up, press the down button and vice versa.
4. USE EXTREME CAUTION. When using the bypass plug,
the limit switches will no longer shut down the lift when
it reaches the end of its travel. This means you must
NOT run the lift either all of the way up or down.
5. When going up, stop short of the “Stop Here” decals
located on the corner post.
6. When going down, stop as soon as the cradle stops
moving.
TROUBLE SHOOTING
OPTIONAL LIGHT SYSTEM
The optional light system has a circuit breaker on the
Advanced Switch Control (ASC) (Fig. 5 on page 6)
If the circuit breaker trips:
Step 1: Check to see if the light bulb(s) is good.
Step 2: Check to see if the wireless remote is working by
trying to raise and lower the lift. If the wireless
remote is not working, see the trouble-shooting
steps on page 10.
Step 3: Check wiring to make sure coating has not rubbed
away exposing the internal wires.
