Chromalox 1604-7 user manual P41 = Control action type, P43 = Set point indication

NOTE: when the instrument detects an out of range condition, it assignes the P38 value to the PID output but P18 and P20 parameter are still active.

P39 = Digital filter on the displayed value It is possible to apply to the displayed value a digital filter of the first order with a time constant equal to :

-4 s for TC and RTD inputs

-2 s for linear inputs nOFL. = no filter

FLtr = filter enabled

P40 = Digital filter on the retransmitted value This parameter is available only if P5 = PV.rt.

It is possible to apply to the retransmitted value a digital filter of the first order with a time constant equal to :

-4 s for TC and RTD inputs

-2 s for linear inputs nOFL. = no filter

FLtr = filter enabled

P41 = Control action type

This parameter is skipped when none of the outputs is programmed as control output.

Pid. = The process is controlled by PID action. Pi. = The process is controlled by PI action.

negative value decreases the low limit of the anti- reset-wind up (under set point).

P43 = Set point indication

Fn.SP = during operative mode, when the instrument performs a ramp, it will show the final set point value.

OP.SP =during operative mode, when the instrument performs a ramp, it will show the operative set point.

P44 = Operative set point alignment at instrument start up

0 = At start up, the operative set point will be aligned to SP or SP2 according to the digital input status.

1 = At start up, the operative set point will be aligned to the measured value, the selected set point value will be reached by the programmed ramp (see Grd1 and Grd2 operative parameters).

NOTE: if the instrument detects an out of range or an error condition on the measured value it will ever operate as described for P44 = 0.

P42 = Extension of the anti-reset-wind up Range: from -30 to +30 % of the proportional band.

NOTE: a positive value increases the high limit of the anti-reset-wind up (over set point) while a

The configuration procedure is terminated and the display returns to show "COnF".
