Only set a value different from zero if you wish to limit the analog output range; for
instance: for a full scale value of 10000 kg you require an 4 mA signal at 5000 kg
and
20 mA at 10000 kg, in this case, instead of zero, set 5000 kg.
-
: set the weight value for which you wish to obtain the maximum analog output
value; it must correspond to the value set in the PLC program (default: calibration full
scale). E.g.: if I am using a 4-20 mA output and in the PLC program I wish to have 20 mA
= 8000 kg, I will set the parameter to 8000.
-
: analog output correction to zero: if necessary adjust the analog output, allowing the
PLC to indicate 0. The sign ‘-‘ can be set for the last digit on the left. E.g.: if I use a 4-20
mA output and, with the minimum analog setting, the PLC or tester read 4.1 mA, I must set
the parameter to 3.9 to obtain 4.0 on the PLC or tester.
-
: full scale analog output correction: if necessary adjust the analog output, allowing
the PLC to indicate the value set in the
parameter. E.g. if I use a 4-20 mA output
with the analog set to full scale and the PLC or tester reads 19.9 mA, I must set the
parameter to 20.1 to obtain 20.0 on the PLC or tester.
Minimum and maximum values which can be set for the zero and full scale
corrections:
NOTE: the analog output may also be used in the opposite manner, i.e. the weight setting that
corresponds to the analog zero (
) may be greater than the weight set for the analog full
scale (
). The analog output will increase towards full scale as the weight decreases; the
analog output will decrease as the weight increases.
E.g.:
= 10000
= 0 analog output 0-10 V
Weight = 0 kg analog output = 10 V
Weight = 5000 kg analog output = 5 V
Weight = 10000 kg analog output = 0 V
