Time in seconds before the alarm trips (see 4)
1.
This is the lowest operating level (in mV) of any load cell connected. The alarm will activate if
any load cell falls below this value.
2.
This is the highest operating level (in mV) of any load cell connected. The alarm will activate
if any load cell exceeds this value.
3.
This is the permissible difference (in mV) between any 2 load cells. The alarm will activate if
this value is exceeded.
4.
This is the time (in seconds) an error must be present before the error alarm is displayed and
output via the relay.
The Error Displays on the LCI
Note:
On Power Up the display will show either ‘
good’
or (‘ ’)
.
Listed below is the range of errors which may
occur, due to fault conditions in the weighing system, load cells or associated wiring.
Display digit 1 shows which load cell is in error. Digits 2 and 3 show an error by displaying ‘ ’. Display digit
4 displays any of five fault conditions as follows:-
Error Condition 1
An open or short circuit on the load cell or connectors
(Check wiring and power supply)
Error Condition 2
The load cell input is open circuit or has exceeded ± 50mV
(Check wiring and power supply)
Error Condition 3
Operating outside the pre-set maximum and minimum range (
&
)
(Check wiring, cell mounting, Max /Min operating ranges)
Error Condition 4
The load cell balance has exceeded the pre-set balance band (
)
(Check wiring, cell mounting, error band values)
Error Condition 5
Open circuit of the excitation on the load cell or wiring.
(Check wiring)
