Proportional Band:
p
When the character
p
is displayed on the PV display, the propor-
tional band (P constant) can be changed using the Up and Down
Keys. The new value will be displayed on the SV display. It can be
set in a range from 0.0 to 999.9% FS in units of 0.1% FS. The factory
setting is 10.0% FS.
Integral Time (Reset Time):
i
When the character
i
is displayed on the PV display, the integral time
(I constant) can be changed using the Up and Down Keys. It can be
set in a range from 0 to 3,999 seconds in units of 1 second. The fac-
tory setting is 240 seconds.
Derivative Time (Rate Time):
d
The derivative time (D constant) can be changed when the charac-
ter
d
is displayed on the PV display using the Up and Down Keys. It
can be set in a range from 0 to 3,999 seconds in units of 1 second.
The factory setting is 60 seconds.
Process Value
Manual output value (only in manual output mode) and main setting
can be changed when process value is displayed by using the Up
and Down keys.
Selecting the Output Mode
The A/M Key can be pressed for one second or longer to change
between the auto and manual output modes.
Auto Output Mode
In auto output mode, the control will function automatically. When
the A/M Key is pressed and the auto output mode is first entered,
