On 5G output models (output catalog No. appended with 5G), you can choose between use as a
controller or a programmer. Set this in setup data
C

. You can also choose between controller
or programmer functions even if the
DCP31
is used for program operation or constant-value
operation.
The
DCP31
is limited to use as a controller at all times on other models.
●
●
Controller
When the
DCP31
is used as a controller, PID control operation is
carried out according to PV, SP AND PID setting values, and the
resulting manipulated variable (MV) is output as an analog output.
ON-OFF control, heat/cool PID control and 3-position-proportional
is also possible depending on the type of output supported by the
model of
DCP31
.
In the MANUAL mode, the MV can be incremented or decrement-
ed in the basic display state by the console keys.
●
●
Programmer
When the
DCP31
is used as a programmer, PID control operation is
not carried out, and the SP is output in the scaled 4 to 20mA range.
In the MANUAL mode, the SP can be incremented or decremented
in the basic display state by the console keys.
