4 10 Digital Filter

In certain application the process value is too unstable to be read. To improve
this a programmable low pass filter incorporated in the BTC-2500 can be used.
This is a first order filter with time constant specified by

parameter which

is contained in setup menu. The default value of FILT is 0.5 sec. before
shipping. Adjust FILT to change the time constant from 0 to 60 seconds. 0
second represents no filter is applied to the input signal. The filter is
characterized by the following diagram.

Filter Characteristics

The Filter is available only for PV1, and is performed for the displayed value
only. The controller is designed to use unfiltered signal for control even if Filter
is applied. A lagged ( filtered ) signal, if used for control, may produce an
unstable process.
