5.3 Reducing Input Variations
•
If input noise or variations cause the
low-order display digits to fluctuate so
that the displayed value is difficult to
read, filtering of inputs will reduce the
variations.
•
Filtering is used by setting a 1st-order
lag time constant; this is set using the
parameter "FL" (PV input filter).

equipment, it may be necessary not to
allow use of the full setpoint operating
range, but rather to some narrower range.
•
In such cases, the minimum value and
maximum value of target setpoint can be
set to restrict the setpoint to the range
between those values.
•
The minimum value and maximum
value of target setpoint are set using the
parameters "SPL" (minimum value of
target setpoint) and "SPH" (maximum
value of target setpoint).
