10 PL9700 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
w i r e s f r o m t h e b a c k o f t h e i n d i c a t o r.
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
w i r e s f r o m t h e b a c k o f t h e i n d i c a t o r.
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
T h e q u a l i t y o f th e s i g n a l f r o m t h e c h a n n e l 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
c h a n n e l 2 t e r m i n a l s t o t h e c h a n n e l 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.
