16 PL9710 Installation Manual
Ch.2 not connected
Channel 2 is not connected to its transmitter.
• The channel 2 wire may have been disconnected at
the back of the indicator.
• The channel 2 wire may be damaged between the
channel 2 transmitter and the indicator. Disconnect
the channel 1 wires from the indicator. Assuming
channel 1 is working, connect the channel 2 wires to
the channel 1 terminals. If the message stays the
same, the indicator is defective. If the message goes
away and channel 2 works again, then the wire is
the problem. Check for a cut wire or a connector
unplugged.
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.
