Output Adjustment Functions Section 4-17
4-17-3 MV at PV Error
If the Direct Setting of Position Proportional MV parameter is set to ON during
close control, the valve opening can be specified. The default setting is 0.0
(i.e., the open and close outputs are adjusted so that valve opening will be 0).
Parameter
name
Setting range Unit Default
MV at STOP −5.0 to 105.0 for standard control
−105.0 to 105.0 (heating/cooling control)
Position-proportional Control
Close control and Direct Setting of Position
Proportional MV parameter ON: −5.0
to 105.0
Floating control or Direct Setting of Position
Proportional MV parameter OFF:
CLOS (Control output 2 ON)
HOLD (Control outputs 1 and 2 both
OFF)
OPEN (Control output 1 ON)
% or none 0.0 or HOLD
Note The order of priority is as follows: Manual MV > MV at stop > MV at PV error.
The following table shows the operation when a potentiometer error
occurs when the Direct Setting of Position Proportional MV parameter is
set to ON.
MV at stop ≥ 100
MV at stop ≤ 0
Open output ON
Close output ON
When the MV at stop is other than the above, the open and close outputs
will both be OFF.
A fixed MV is output for an input error, RSP input error, or potentiometer
error (close control only). To set the MV at PV error, set the MV at Stop
and Error Addition parameter (advanced function setting level) to ON.
The MV at stop takes priority when stopped and the manual MV takes priority
in manual mode.
■ Standard Models
With heating/cooling control, the MV on the cooling side is taken to be a negative
value, so the output is made to the heating side for a positive value and
to the cooling side for a negative value. The default setting is 0.0 (i.e., there
are not outputs for either standard control or heating/cooling control).
■ Position-proportional Models
Open, close, or hold status can be selected for floating control or when the
Direct Setting of Position Proportional MV parameter is set to OFF. With open
status, only the open output will turn ON. With close status, only the close output
will turn ON. With hold status, the open and close outputs will both turn
OFF. The default setting is for hold status, with no outputs.
