Range
The following parameter is present if a motorised valve controller has been ordered
MTR.T
MOTOR TRAVEL TIME.
Set this value to the time that it takes for the
motor to travel from its fully closed to its fully open position.
Note: In motorised valve control only the PB and TI parameters are
active – see below. The TD parameter has no effect on the control.
0.0
to
999.9
seconds
This section applies to control the parameters. A further description of theses parameters is given in section
11 of the Engineering Handbook part no. HA028651.
A.TUNE
AUTOTUNE
Automatically sets the control parameters to match the
process characteristics.

PB
PROPORTIONAL BAND
Sets an output which is proportional to the
amplitude of the error signal. Units may be in % or display units.
1 to 9999 display units
Default 20
TI
INTEGRAL TIME
Removes steady state control offsets by ramping the
output up or down in proportion to the amplitude and duration of the
error signal.
Off
to 9999 seconds
Default 360
TD
DERIVATIVE TIME
Determines how strongly the controller will react to
the rate of change temperature. It is used to prevent overshoot and
undershoot, and to restore the PV rapidly if there is a sudden change in
demand.
Off
to 9999 seconds
Default 60 for PID control
Default 0 for valve position
