4.6.1 Measuring Circuit Error Messages
The weighing electronics can generate error messages, which are output on the weight display.
Display VNC text Cause
EPPOP1 Arith err Internal arithmetic overflow (faulty calibration values)
EPPOP2 Overload Input voltage is higher than Max + (x d)
EPPOP3 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
EPPOP6 No sense
voltage
Load cells not connected. Sense line or supply line is interrupted or
connected with wrong polarity or sense voltage is low
EPPOP7 Negative Input Input voltage is negative (e.g. wrong polarity of load cell signal or
supply voltage)
Testing the Measuring Circuit
A simple test with the load cells connected can be carried out with a multimeter
(not with external supply or intrinsically safe load cell interface):
12 VDC +/- 0.8 V
(symmetrical to housing GND) 12 VDC +/- 0.8 V
(symmetrical to housing GND) 0 - 12 mVDC @ LC with 1.0
mV/V
0 - 24 mVDC @ LC with 2.0
mV/V
Supply voltage Sense voltage Measuring voltage
