Low Reading
Enter the input signal level that corresponds to the low
process variable (LO PV) you entered in the previous pa-
rameter.
Selectable values: For linear inputs, any value between
-99.9% and 999.9% percent of full scale, where 100% cor-
responds to 60mV and 0% corresponds to 0mV. For pulse
inputs, any value between 0 and 2000 HZ. The low reading
must be less than the high reading (HI RDG).
Input Filter
The controller has two types of input filtering:
• The rejection filter ignores sensor readings outside the
acceptance band when subsequent readings are within
the band. For temperature sensors, the band is ±5˚
about the last accepted reading. For linear inputs the
band is ±0.5% of the input range. This filter is not ad-
justable.
• A simulated resistor-capacitor (RC) filter damps the
input response if inputs change unrealistically or
change faster than the system can respond. If the in-
put filter is enabled, the process variable responds to
a step change by going to 2/3 of the actual value within
the number of scans you set.
Selectable values: 0 to 255 scans. 0 disables the filter.
