Omron E5 J Series User Manual

E5jJ
E5jJ
• 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 T ime : 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 T ime : 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 V alue 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 T emperature Controller will be bal -
anced
with a deviation value between the set point and process val -
ue. This deviation value is called the of fset. By changing the manual
reset value, the of fset can be eliminated.

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 -
