P-38
Derivative time (0.0/999.9 sec). (0 excludes derivative)
Parameters for P.I.D. control on process 1.
Dead band limits the zone where PID is not active - Proportional
band refers to inertia of process and is expressed as units (ex.
°C) – Integral time express inertia of process as seconds –
Derivative time has a damping function and is usually ¼ of
integral time
P-39
Lower limit Setpoint2 (-999/9999 digit).
P-40
Upper limit Setpoint2 (-999/9999 digit).
Lower and upper limits of
Setpoint2
when both inputs are active
but only one is referring to the programmed cycle (
see P-05, 3
rd
Digit
) and the second one is referring to a fixed setpoint (which is
setpoint2)
P-41
Offset calibration input AN2 (-15.0/15.0 digit)
P-42
Gain calibration input AN2 (-10.0%…+10.0%)
These parameters act to adjust eventual errors of sensors or to
fix correspondance with a precise point of the scale
P-43
Max. time for impulse in zone 2 (1/120 sec).
Cycle time
for time-proportioned outputs (see
P-30
). This
parameter is configured only if two zones are enabled (An1 and
AN2 both configurated).
P-44
Limit of command signal for zone 2 (10/100%)
See
P-31
.
P-45
ON/OFF hysteresis; P.I.D. dead band (-99.9/300.0 digit)
P-46
Proportional band (0-3000 digit). (0 excludes P.I.D)
P-47
Integral time (0/9999 sec). ( 0 excludes integral)
P-48
Derivative time (0.0/999.9 sec). (0 excludes derivative)
Parameters for P.I.D. control on zone 2
