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

TROUBLESHOOTING
PROBLEM
PROBABLE CAUSE
CORRECTION
System will not operate
after normal start-up
procedure
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 is
transmitting (Power
LED flashing), but
crane/machine will not
respond
E-Stop switch engaged
Pull out the E-Stop pushbutton and
activated switch on transmitter.
Transmitter out of range
Take the transmitter back into the range of
the receiver.
Receiver power off
Turn on power to receiver.
E-Stop failure in transmitter
Check E-Stop pushbutton for damage.
Check wiring to contact element for broken
or disconnected wires. Repair or replace
E-stop pushbutton or wiring.
All crane/machine
motions operate
intermittently
Receiver antenna loose or
missing
Tighten or replace antenna.
External antenna (if used) has
loose connection, poor grounding
or interference
Tighten antenna and ground connection.
See "Connecting an External Antenna"
Section for operational precautions.
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.
Some crane/machine
motions operate
intermittently
Crane/machine motion wiring
may be loose.
Check wiring from receiver to plug and from
plug to crane/machine motion actuator.
