56 Precision Loads On-Board Weighing Installation & Service Manual
ERROR Reset Ch1 empty weight out-of-range 3000
The difference between the original empty weight and the current empty weight is too large for the recall empty
weight command to function. The difference is limited to 3000 lbs or 2500 kgs.
Check for other problems, such as:
• Bent or distorted load cell
• Damaged load-cell mounting
• Bent truck or trailer frame
• Defective load cell
ERROR Ch1 cable shorted. Check all connections
The channel 1 wires are shorted together or shorted to the truck frame.
• Disconnect the channel 1 wires from the back of the indicator. If the error message remains, the indicator is
defective. If the message goes away, check the channel 1 wire.
• The channel 1 wires may be damaged between the load cell and the transmitter or between the transmitter
and the indicator.
• Check all wires for cuts or for pinched areas.
• Check for worn insulation where the wire could be shorted to the truck or trailer frame.
ERROR Ch2 cable shorted. Check all connections
The channel 2 wires are shorted together or shorted to the truck frame.
• Disconnect the channel 2 wires from the back of the indicator. If the error message remains, the indicator is
defective. If the message goes away, check the channel 2 wire.
• The channel 2 wires may be damaged between the load cell and the transmitter or between the transmitter
and the indicator.
• Check all wires for cuts or for pinched areas.
Check for worn insulation where the wire could be shorted to the truck or trailer frame.
No signal Ch.1
The signal from the channel 1 transmitter is not being received at the indicator.
• Disconnect the black and white channel 1 wires from the back of the indicator. Assuming channel 2 is
working, move the black and white channel 2 wires from channel 2 to the channel 1 terminals. If the error
message remains, then the indicator is defective.
• If the error message goes away and channel 1 again works, check for a cut wire between the indicator and the
channel 1 transmitter. Check also for a good connection at the channel 1 transmitter.
No signal Ch.2
The signal from the channel 2 transmitter is not being received at the indicator.
• Disconnect the black and white channel 2 wires from the back of the indicator. Assuming channel 1 is
working, move the black and white channel 1 wires from channel 1 to the channel 2 terminals. If the error
message remains, then the indicator is defective.
• If the error message goes away and channel 2 again works, check for a cut wire between the indicator and the
channel 2 transmitter. Check also for a good connection at the channel 2 transmitter.
Bad signal Ch.1
The quality of the signal from the channel 1 transmitter is poor.
• Disconnect the channel 1 wires from the back of the indicator. Assuming channel 2 is working, move the
channel 2 wires from the channel 2 terminals to the channel 1 terminals. If the error message remains, then
check the voltage at the power cable. If should be between 11.5 and 16 volts.
• If the voltage is good, then make sure the power lead is connected directly to the battery. Power from any
other source may be too “noisy”.
• If the error message still remains, then the indicator may be defective.
• If the message is gone when the channel 2 wires are substituted for channel 1, then the channel 1 transmitter
is defective or the connector may not be plugged in correctly.
