matching. Compare the 12 position address
switches in both transmitter and receiver and
then repeat step 3B. If they both match and still
the power relay doesn’t engage, set all 12 of the
dip switches to the OFF position in both the
receiver and transmitter and then repeat step
3B. At this point if the radio controller works or
not, call the factory to either be assigned a new
address code or to have the controller shipped
back to the factory for repair.
4. With a function activated and all three indicator
LED’s ON and there is no voltage registering on
the voltmeter, check the output fuse. There is a
7.5 amp fast blow fuse on each output. There is
an extra fuse and clip on the PC board. Remove
and replace blown fuse. If fuse repeatedly fails,
you may have a dead short in your wiring
harness or the electric coil or relay is failing. Do
not use anything other than the recommended
fuse furnished on the receiver PC board.
c. If the transmitter face plate has been removed and
replaced, then three problems could have been
introduced. Troubleshoot as follows:
1. Remove faceplate from transmitter. Make sure
that leads to each lead screw on toggles are
secure and will not be at an angle where it
would be touching anything when replacing the
faceplate.
2. Disconnect wiring harness from PC board and
then reconnect the same way. Be sure that no
wires are loose at connector and that connector
is secure on connector pins. The wiring harness
should be positioned between toggle housings
or where it is not hanging down creating a bind
when replacing the faceplate.
3. Refer to 3B.
Example to follow on existing equipment
4. Activate a function (boom up) on the transmitter, at this
time the receiver’s RF Indicator LED and the appropriate
Output Status Indicator LED will be on. And if the
function activated, such as the boom up motion does not
occur, check the following:
a. Be sure that the appropriate orange connector pin
matches the Output Status Indicator LED. There
s h o u l d b e 1 2 o r 2 4 v o l t s D C t o t h a t o u t p u t ,
depending on the power supplied from the vehicle. If
it is determined there is power to the output, then
the wiring and hydraulic system should be checked.
b. If the appropriate Output Status Indicator LED is
turned on and there is no power to the orange
connector pin, this indicates that a circuit failure has
occurred and the radio controller must be repaired
at the factory.
5. If crane function occurs when function switch is
activated and before trigger is pulled, readjust the low
end proportional potentiometer in the receiver. See
Installation Section for correct procedure.
