Error code 201
.
This is indicating that the signal from the main load sensor is too low or
too high. This should be confirmed by viewing function code (F-1 5)
“VIEW UNCALIBRATED TRANSDUCER 1 INPUT” and noting that the
value shown on the LOAD LCD display is lower than 33, or higher than
999.
Possible causes:
•
Load cell signal wires shorted together.
•
The is shorted to the shield.
•
The excitation - is shorted to the shield.
•
The excitation supply is shorted together. This will obviously affect
all of the external sensors. Measure the ex citation voltage and
compare it with the expected value. I f this is the cause, the
UNCALIBRATED value will generally be non-zero, but below 33.
•
The load cell is disconnected or there is an open circuit in one of the
signal wires.
•
The signal - is connected to the shield.
•
The and the exci are swapped.
•
The signal - and the excitation - are swapped.
Error code 202
.
This is indicating that the signal from the auxiliary load sensor is too low
or too high. This should be confir med by v iewing function code (F-19)
“VIEW UNCALIBRATED TRANSDUCER 2 INPUT” and noting that the
value shown on the LOAD LCD display is lower than 33, or higher than
999.
Possible causes:
•
Load cell signal wires shorted together.
•
The is shorted to the shield.
•
The excitation - is shorted to the shield.
•
The excitation supply is shorted together. This will obv iously affect
all of the external sensors. Measure the excitation volt age and
compare it with the expected value. I f this is the cause, the
UNCALIBRATED value will generally be non-zero, but below 33.
•
The load cell is disconnected or there is an open circuit in one of the
signal wires.
•
The signal - is connected to the shield.
•
The and the exci are swapped.
•
The signal - and the excitation - are swapped.
Error code 240
.
This is indicatin g that an overload h as been detected. This error
generally accompanies most other er rors simply because most oth er
errors will place the display into an overload condition. This being the
case, you need to check what other errors are present and correct them
first. Once these have been addressed the E240 error generally takes
care of itself. The exception is of course, when the equipment has been
put into a genuine overload situation which has not been caused by any
external faults.
