fault Cause Remedy
- 01 -
Converter faulty
Load cell connection
faulty or missing
Check extension lead, junction box, load
cells
- 01 -
Converter faulty
(*) Response signal
from load cell more
than approx. + +23 mV
or less than approx. - -
23 mV.
Check that the load cell is in good order and
is working within its prescribed range
- 01 -
Converter faulty
(*) Board faulty
Check the converter board using a load
cell simulator. If the test result is negative,
replace the converter board.
- 01 -
Converter faulty
(**) The digital cells fail
to respond
Check the load cell connections
- 02 -
Parameter memory
error
Error in the data
contained in the
parameter memory of
the board
Check the linearized calibration
parameters
- 06 -
(**) Serial number
error in digital load cell
Check the serial numbers and calibrate the
angles if necessary
- 07 -
(**) Faulty load cell
in a multiple load cell
system
Replace the load cell and calibrate the
angles or calibate the angles of the single
load cell
- 08 - (**) Scale board faulty
Replace the scale board and calibrate the
angles or reset the terminal data (if they
had been saved before the fault)
- 09 -
(**) Before powering
the system
Calibrate the angles
- 10 -
(**) At least one load
cell is not configured
Calibrate the angles
- 11 -
(**) Digital load cell
power supply faulty
Check the cables and power supply voltage
- 12 -
(**) Digital load cell
power supply faulty
Replace the load cell with the error
indication
- 13 -
(**) Load cell with
temperature beyond the
/-40 to 100°C) range
Replace the load cell with the error
indication
Calibrate the angles for the replaced load
cell.
- 21 --
(**) Digital load cell
temporary error
