5.5.1 Measuring Circuit Error Messages
The weighing electronics can generate error messages, which are output on the weight display.
VNC Text Cause
Arith err Internal arithmetic overflow (faulty calibration values)
Overload Input voltage is higher than Max + (x d)
No EOC Input signal is higher than the permissible range of 36 mV. However, the
trouble cause can also be due to an error in the analog section, to a
defective load cell or to a cable break
No sense
voltage
Sense line or supply line is interrupted or connected with wrong polarity or
sense voltage is low
Negative
Input
Input voltage is negative (e.g. wrong polarity of load cell signal or supply
voltage)
5.5.1.1 Testing the Measuring Circuit
A simple test with the load cells connected can be carried out using a multimeter (not with external supply
or intrinsically safe load cell interface):
12 V +/- 0.8 V
(symmetrical to housing GND)
12 V +/- 0.8 V
(symmetrical to housing GND)
0 - 12 mV @ LC with 1.0 mV/V
0 - 24 mV @ LC with 2.0 mV/V
Supply voltage Sense voltage Measuring voltage
