stellar labs 5520 - Radio Remote Troubleshooting

Troubleshooting 
Transmitter
• Is the E-Stop pushbutton pulled out?
• Are all the switches in their center
(neutral) position.
• Are the batteries in the transmitter fully
charged?
• Is the transmitter inside its operating
range?
Receiver
• Is the antenna plug securely
connected?
• If there is an external antenna, is the
antenna connection assembly outside
the enclosure secure?
• Are the power supply and ground wires
securely fastened?
• Are the signal wires separated from the
power supply wires?
Radio Remote Troubleshooting
If the system does not operate after normal start-up, follow the recommended
troubleshooting sequence to help isolate the cause and determine corrective action.
PROBLEM PROBABLE CAUSE CORRECTION
E-Stop switch engaged. Pull out E-Stop switch.
Batteries fully discharged
Check batteries to ensure a full charge. Replace with
new batteries if necessary.
No power to the receiver.
Check the diagnostic LED on the receiver to be sure
power is applied. Ensure that the system is properly
grounded.
Transmitter out of range. Take the transmitter back into the range of the receiver.
Receiver power off. Turn on power to receiver.
Power Supply malfunctioning. Repair power source connection.
Blown fuse. Replace fuse.
Receiver antenna is loose or
missing.
Tighten or replace antenna.
External antenna (if used) has
loose connection, poor grounding
or interference.
Tighten antenna and ground connection.
Ground wiring is poor. Conductor
is too small, or receiver is
grounded to chassis.
Ground wiring must be connected to machine power
source ground. Minimum diameter of conductor ground
is 12 AWG.
Receiver has no yellow flashing
LED light.
Blown fuse or poor ground Replace fuse or repair ground circuit
Transmitter LED light will not
flash green when a toggle
switch is activated.
E-stop switch failure, weak/dead
"AA" batteries or corrosion on
Coder board due to water
damage
Replace e-stop switch. Install new alkaline "AA" batteries.
Replace coder board.
Transmitter LED light flashes
green and the receiver light
flashes yellow.
Transmitter has lost
communication with the receiver.
Baud rate programming does not
match.
Re-link or learn the transmitter to the receiver. Return to
Stellar Industries to be programmed.
Transmitter LED light flashes
green, then begins to flash red.
Transmitter "AA" batteries are
weak.
Replace "AA" batteries.
Transmitter LED light stays on
and is solid red.
E-stop switch failure or possible
corrosion on the coder board
inside the transmitter.
Replace the e-stop switch or replace the coder board.
Transmitter LED light stays on
and is solid green.
Toggle switch has failed or coder
board has lost
programming.
Locate and replace failed toggle switch. Replace
coder board.
Radio system seems to operate
intermittenly.
Frequency interference,
damaged battery tube holder or
antenna failure.
Use 25 ft. back up cord for areas with high frequency
interference. Check battery tube holder for damage.
Replace antenna if needed.
Receiver LED light flashes
yellow and then to red, when a
toggle switch is activated from
the transmitter.
Poor ground circuit or receiver
failure.
Check ground circuit for loose, corroded or broken wires.
Replace radio receiver.
Transmitter loses programming
while in the sleep mode and
has to be re-linked to the
receiver
Coder board is weak or is failing. Replace the coder board.
System will not operate after
normal start-up procedure.
All crane motions operate
intermittently.
No yellow light flashing on the
receiver
Transmitter is transmitting
(Power LED flashing), but crane
will not respond.
