Inputting Parameters
The temperature Controller has two display levels 0 and 1, in which only specific parameters can be set. Level 0 is the initial level and is auto -
matically
entered upon power application. T o change the mode to set or change a dif ferent group of parameters, hold down the Level Key for
1 second minimum. The display level mode changes as shown below . Actual displays vary with models and switch settings. If a display does
not appear as expected, check your switch settings.
Besides
the functions explained here, the T emperature Controller incorporates an alarm hysteresis function, set point limit function, automatic
return of display mode function, input shift function, and event input 2 type selection (incorporated by the E5AJ and E5EJ only). Refer to the
E5 j J Operation Manual (Z103) , which can be obtained from your OMRON representative, for details on these functions.

The

In the case of 2-PID, the relay output or voltage output repeats turn -

called a control period. The
duration that the output is ON is in proportion to the output value.
The
shorter the control period is, the smoother the control operation
will be. If the control period is, however , too short, the life of the relay
will be shortened. Therefore the control period should be 20 s mini -

Heater Burnout Alarm V
alue Setting: hb
The
current value to detect heater burnout can be set within a range
of 0.0 to 50.0 A.
The current value is factory-set to 0.0 A. Check the normal heater
current
and the current at the time of heater burnout from the heater
current value display , and set the set value to the mean value of the
current values (i.e., set value = (normal current value + heater burn -
out
current) B 2).
If the dif ference between the normal heater current and heater burn -
out
current is small, heater burnout detection will not be stable. For
stable detection, the dif ference in current must be 1.0 A minimum if
the heater input is less than 10.0 A and 2.5 A minimum if the heater
input is 10.0 A or more.
Note: 1. Do not allow a current exceeding 50 A to flow in the CT ;
the
maximum continuous heater current is 50 A.
2. Set the value to 0.0 A if the heater burnout alarm is not
used, in which case the alarm will not function at all.

Note: Always
turn on the Controller and the load simultaneously .
Never

For

E5jJE5jJ
Fuzzy Self-tuning
Fuzzy self-tuning is a function that enables the E5jJ to calculate
the
most suitable PID constants for the controlled object.
Features
The E5 j J judges by itself when to perform fuzzy self-tuning.
Fuzzy Self-tuning Function
The fuzzy self-tuning function has three modes.
In SR T (step response tuning) mode, the PID constants are tuned
using a step response method at the time the set point is changed.
In DT (disturbance tuning) mode, the PID constants are amended
so that the controlled temperature will be within the target range
set in advance when there is external disturbance.
In HT (hunting tuning) mode, when hunting occurs, the PID
constants
are amended to suppress the hunting.
Note: Be sure to turn on the power supply to the load either before
or simultaneously with the start of T emperature Controller
operation.
Dead
time will be measured from the time the T emperature
Controller starts operating. If a load such as a heater is
turned on after the Temperature Controller is turned on,
dead time longer than the actual value will be measured
and
inappropriate PID constants will be obtained. If an ex -
tremely
large amount of dead time is measured, the control
amount will be set to 0% for a short period of time before
being
returned to 100%, and the constants will then be re -
tuned. Retuning is performed only for large amounts of
dead
time, so be sure to follow the precaution given above
when starting operation.
Startup Conditions of SRT
SRT
will start if the following conditions are satisfied simultaneously
when the E5 j J is turned on or the set point is changed.
At the time the E5 j J starts
operating
At the time set point is
changed
1. The set point at the time the
E5jJ starts operating is
different from the set point
used at the time SRT was
last
executed (see note).
2. The dif ference between the
set point and the process
value at the time the E5jJ
starts operating is larger
than
the present proportion -
al
band value (P) x 1.27+4.
3. The process value at the
time the E5jJ starts oper-
ating
is smaller than the set
point in reverse operation
and
larger than the set point
in normal operation.
1. The new set point is differ-
ent from the set point used
at the time SRT was last
executed
(see note).
2. The set point changing
range is larger than the
present proportional band
value
(P) x 1.27+4.
3. The process value is in
stable condition before the
set
point is changed.
4. A larger set point value is
set
in reverse operation and
a smaller set point is set in
normal
operation.
Note: The last SR T -executed set point is set to 0 before shipping
and when changing from 2-PID control to 2-PID control with
fuzzy self-tuning.
Imposition Completion Condition of Step Control Amount
In order to prevent overshooting, the step controlled amount must
be imposed continuously only while the present deviation is the
same as or greater than the value obtained from the proportional
band
(P) x 1.27. The step control will not be applied when the devi -
ation
becomes smaller than this value.
PID Constant Refreshing Conditions
If the step control amount is applied before the maximum tempera -
ture
slope (R) is obtained, SR T will not renew any PID constant. If
the proportional band obtained from the R and L values that were
measured
before the imposition had been completed is larger than
the present proportional band, the PID constants will be renewed
because
the measured value is in the direction towards the suitable
proportional band value, and the set point at that time will be the
SRT-executed
set point.

Stable T emperature Status
If the temperature is within the stable range for a certain time, it is
deemed that the temperature is stable. This time is called stability
judgement
time. Like PID constants, stability judgement time is ad -
justed
with fuzzy self-tuning according to the characteristics of the
object to be controlled. Fuzzy self-tuning will not be activated if the
temperature is stable because the Temperature Controller deems
that
temperature control is smooth.

Balanced Status
If the process value is within the stable range for 60 s when there is

Startup Conditions of DT
1. DT
will start if the temperature that has been stable varies due
to external disturbance and the deflection of the temperature
exceeds the stable range, and then the temperature
becomes stable, provided that the number of maximum
temperature
values is less than four .
2. DT
will start if the set point is changed under the condition that
SRT does not start and the temperature becomes stable,
provided
that the number of maximum temperature values is
less than four .
If there are four or more maximum temperature values, HT
will

Auto-tuning
Starting Auto-tuning
Auto-tuning can be started by using the following procedure. Use
this
procedure when appropriate results are not achieved via fuzzy
self-tuning.
1. Turn ON pin 3 of the function selector switch to select the
2-PID
control mode (refer to page 8 ).
2. Press
the Level Key and the Display Key simultaneously for
1 s or longer to start auto-tuning.
Conditions that Prevent Auto-tuning
You will not be able to start auto-tuning when any of the following
conditions exist.
•When the control mode is set for ON/OFF control or 2-PID
control
with fuzzy self-tuning.
• When an engineering level parameter is displayed.
• When the key protection switch is set to SP or ALL.
• When the remote/local setting is set to remote.
• When the RUN/STOP setting is set to ST OP.
•When a sensor error , memory error , or A/D converter error has
