If the control mode is 2-PID with fuzzy self-tuning, the
parameters
p
,
i
,
d
, or
ofr
will not be displayed (i.e., there is no
need to set these parameters). Fuzzy self-tuning always adjusts
all PID constants to optimum values inside the Temperature
Controller.
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 0.1
°
to 999.9
°
C/
°
F in units of 0.1

C/

F. The value
is factory-set to 8.0
°
C/
°
F. However, the E5
j
J-F (Fahrenheit Model)
is factory-set to 14.4
°
F.
Integral 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 value is factory-set to 233 seconds.
Derivative Time :
d
When the character “
d
” is displayed on the PV display, the deriva-
tive time (D 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 value is factory-set to 40 seconds.
Manual Reset Value Setting (%) :
ofr
The necessary output value in stable state will be set within a range
of 0.0% to 100.0%. The output value is factory-set to 50.0%. In P or
PD mode (i.e., when I is 0), the Temperature Controller will be bal-
anced with a deviation value between the set point and process val-
ue. This deviation value is called the offset. By changing the manual
reset value, the offset can be eliminated.

(Alarm 1 hysteresis
setting)
Displayed if the E5

J with an alarm
function is used (see note 2).
(Alarm 2 hysteresis
setting)
(Set point lower limit setting)
(Set point upper limit setting)
Displayed if the E5
j
J with
event input 2 is used.
(Event input 2 function
selection)
Note: 1. The E5

J-
jjjj

are different. Refer to the E5

J Operation Manu -
al (Z103).
2. The value will not be displayed if the alarm mode
switch is set to 0 or if the E5
j
J does not incorpo-
rate any alarm.
