6 Function Hetronic Radio Remote 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?
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
System will not operate
after normal start-up
procedure.
Transmitter is transmitting
(Power LED flashing), but
crane will not respond
All crane motions operate
intermittently
Some crane motions
operate intermittently
PROBABLE CAUSE
E-Stop switch engaged
Batteries fully discharged
No power to the receiver
E-Stop switch engaged
Transmitter out of range
Receiver power off
E-Stop failure in transmitter
Receiver antenna is loose or
missing
External antenna (if used) has
loose connection, poor
grounding or interference
Ground wiring is poor.
Conductor is too small, or
receiver is grounded to
chassis.
Crane motion wiring may be
loose.
CORRECTION
Pull out E-Stop switch.
Check batteries to ensure a full charge.
Replace with new batteries if necessary.
Check the diagnostic LED on the receiver to
be sure power is applied. Ensure that the
system is properly grounded.
Pull out the E-Stop push button and activated
switch on transmitter.
Take the transmitter back into the range of the
receiver.
Turn on power to receiver.
Check E-Stop pushbutton for damage. Check
wiring to contact element for broken or
disconnected wires. Repair or replace E-Stop
push button or wiring.
Tighten or replace antenna.
Tighten antenna and ground connection.
Ground wiring must be connected to machine
power source ground. Minimum diameter of
conductor ground is 12 AWG.
Check wiring from receiver to plug and from
plug to crane motion actuator.
