Troubleshooting
For help with general or miscellaneous problems that you may experience with your ED2 Series SkidWeigh,
refer to the following table for the possible solutions.
Problem
Possible cause
Possible solution
MODE 8
digit is not shown on the
instrument display when the
ignition switch is turned ON
No power to the system
- Check whether the fuse is blown
- Check for a bad ground chassis
connection
- Remove any paint around the ground chassis
connection
- On electric vehicles, make sure that the “Black
wire”, negative is connected to the battery negative,
not to the frame of the vehicle
When in
MODE 8
and the forks
with the load weight are lifted,
there is no weight readout shown
on the instrument display
Pressure transducer or
wiring harness
- Check all 3 wires connections from the pressure
transducer cable
- Check the WHITE wire if connection is broken
- Check the RED wire - it should have at least 11V
DC
- Check the pressure transducer for physical damage
- Replace the pressure transducer
Weight display shows some
random number (Example: 4630)
regardless if forks lowered or any
weight load lifted
Pressure transducer
ground wire (Black wire)
is broken or
disconnected
- Broken Black wire from pressure transducer
- Make sure that the “BLACK WIRE” from the
pressure transducer to the wiring harness is
connected
All display digits are “flashing”
999999 when the ignition switch is
turned ON
The pressure transducer
is near saturation (>
2.45V)
-The load weight is too heavy for this vehicle
- Pressure transducer damaged
When the known load weight is
lifted, there is a “larger weight
readout error”
- Follow a proper
“weighing cycle”.
- Calibration required
- Faulty pressure
transducer
- Recalibrate the system with known load weight
- The system is calibrated in kilograms, but the
operator thinks that readout is in pounds or vice versa
- Follow the “Standard Weighing Cycle” procedure
- Replace pressure transducer
The instrument display shows
approx. the same weight readout
regardless if the forks are loaded
or not
Pressure Transducer
- The white wire (pressure transducer signal output)
is broken or not connected
- Faulty pressure transducer
When the load weight is lifted
display shows the weight value
and display is “flashing”
Overload warning
- The preset overload value is too low
- Check the overload settings and correct it
The lifted load weights are within
the system error of +/- .5 to 1% of
the vehicle lifting capacity most of
the time; but sometimes a “Larger
error might occur”
Follow the proper
weighing cycle error
- Make sure that the standard weighing procedures
are followed.
- When the load weight is lifted, do not move the
vehicle
- When the load weight is lifted, do not tilt the mast
- Replace the pressure transducer
The display will not return to the
MODE 8
, standard weighing cycle
- Forks are not lowered
to the ground
- Pressure transducer
- Lower the forks (attachment) to the ground
(There should be no pressure in the lifting circuit)
- Replace the pressure transducer
