5.5.1.9. Displayed value range limitation
The value range limitation applies only to the main input,
so that it influence only the displayed value
DisplVal
. The value
range limitation parameters are located in the menu in the group
of
Display
parameters:
Over Lo
– lower display value threshold
and
Over Hi
– upper display value threshold. The default value
of upper overflow is 99999 , and for lower overflow
-99999
.
If the lower display overflow occurs the
vvvvvv
, symbol is dis-
played on the display and the number value of the displayed value is
set to -1e20. If the upper display overflow occurs the symbol
is displayed on the display and the number value of the displayed value
is set to +1e20.
5.5.2. Analog output
The PCE-P30U transducer is equipped with one current type
(source) or voltage type analog output depending on the variant code.
5.5.2.1. Analog output individual characteristic
The PCE-P30U transducer enables processing displayed value,
second displayed value and the real time clock value into analog
output signal based on the individual linear characteristic
of the analog output. On the basis of coordinates of two points
provided by the user, the transducer determines (using a system
of equations) a and b individual characteristic coefficients.
where
X1 in
and
X2 in
– the displayed value,
Y1 out
and
Y2 out
– expected value on the analog output.
