1) Verify the signal wires are properly connected.
a) Verify load cell cable color code
(1) Load Cell Certificate.
(2) Installation Manual
(3) Cable marking strips
b) Broken signal wires act as antenna for EMI/RFI.
c) Load cell cable shields must be grounded only at the
controller to dampen EMI/RFI signals.
2) The load cell output signal voltage has exceeded 15 mV DC
a) Use a multimeter to verify mV levels.
B) Verify individual load cell milli-volt signals.
(1) An individual load cell may be over-ranged
and exhibit high milli-volt readings.
(2) Possible physical damage to the load cell
(3) Internal strain gauge bond broke.
(4) Moisture in the load cell cable or body.
3) Weight in the hopper exceeds the configuration Scale Capacity setting.
A) Under configuration verify the Scale Capacity setting.
B) 105% of the scale capacity setting will cause a HI indication.
C) This is used only as a warning and does not effect calibration.
D) Optional communication signals are unaffected by this indication.
4) Weight in the hopper exceeds the load cell capacity
a) Mechanical forces or product acting on the scale overloads the
load cells.
B) Use a multimeter to verify the milli-volt levels.
5) Review Mechanical and Electrical Flow charts for additional tips. B1
Weight Reading is Frozen at Zero or a High Weight Reading
The load sensor output signal has exceeded the millivolt limits set
in Configuration and/or the internal factory setting.
