Setup of PV input range type
1Start from the opera-
tion display (if neces-
sary press [mode]
once to get the op-
eration display).
If the sensor has not
been wired or is discon-
nected, an alarm for
abnormal PV input (any
one from AL0 1to AL11)
may appear on the
upper display.
2Press and hold [para]
for more than 2s to
get the parameter
setup display. a--M
is shown on the
upper display.
In case of ON/OFF con-
trol, r--r appears on
the upper display.
3Press and hold [para]
for more than 2s
again to get the
setup setting display.
The current set
value for C0 1(PV
input range type) is
displayed.
4When the [<], [ ] or
[ ] key is pressed,
the rightmost digit
on the lower display
flashes. If no key is
pressed for more
than 2s after chang-
ing to the desired
value in the PV input
range list, the display
changes from flash-
ing to continuously
lit, and the displayed
value is now set.
Setup of event operation type
In this example, the event 1 operation type is set to deviation high
limit.
1Start from the opera-
tion display (if neces-
sary press [mode]
once to get the op-
eration display).
2Press and hold [para]
for more than 2s to
get the parameter
setup display. a--M
is shown on the
upper display.
3Press and hold [para]
for more than 2s
again to get the
setup setting display.
The current set
value for C0 1(PV
input range type) is
displayed.
4Press [para] repeat-
edly to get e1.c 1on
the upper display. 0
is displayed on the
lower display.
0on the lower display
indicates that the event
operation type is set to
"none."
5When the [ ] or [ ] key is pressed, the rightmost digit on
the lower display flashes. Change the flashing digit to 4by
pressing [ ] or [ ].
If no key is pressed for more than 2s, the displayed value is
set and the display changes from flashing to continuously
lit.
4on the lower display indicates that the event operation type is set for
deviation high limit.
Similarly, use e2.C 1to set the event 2 operation type, and use
e3.C1for event 3.
Red letters : Items before operation

Execution of auto tuning (AT )
AT forces ON/OFF of the MV a number of times (a limit cycle) to cal-
culate PID values.
Check that this operation does not create any problems for the as-
sociated equipment before executing AT.
1Start from the opera-
tion display (if neces-
sary press [mode]
once to get the op-
eration display).
2Press and hold [para]
for more than 2s to
get the parameter
setup display. a--M
is shown on the
upper display.
3Press [para] twice.
The upper display
says at and the lower
display says at.Of.
If the control method
is ON/OFF control and
if Bit 3 (AT stop/start
display) of the mode
display setup (C73) is set
to "disabled: 0," nothing
is displayed.
4When [ ] or [ ] is
pressed, at.Of
flashes.
Flashing occurs only in
RUN and AUTO modes,
if there is no PV input
abnormality.
Also, if "AT stop/start" is
selected for DI assign-
ment, the display does
not blink and no change
can be made.
5[Press [ ] once.
The lower display
starts to flash at.On.
6If no key is pressed
for more than 2s,
at.ON remains
steadily lit and AT
begins.
During AT, the
rightmost decimal
point flashes twice
repeatedly. (When
AT is done, the light
goes off and the new
PID values go into
effect.)
During the AT process, if the mode is changed to READY or
MANUAL, if PV input is faulty, or if a power failure occurs, AT stops
automatically without changing the PID values.
AT can also be stopped by changing the setting from At.ON to
At.OF (return to step 3 above).
Setup of SP value
1Start from the opera-
tion display (if neces-
sary press [mode]
once to get the op-
eration display).
2Check that the op-
eration display is
displaying the SP.
(If not, press [para]
repeatedly until the
SP is displayed.)
3When the [<], [ ] or
[] key is pressed,
the rightmost digit
on the lower display
flashes and the SP
can be changed to
the desired value.
In this case, the flash-
ing of the numerical
value implies that it
is not yet set. A nu-
merical setting that
is being changed
flashes the same way.
If an SP limit is in effect,
the numerical value
cannot be changed to
a value above the limit.
The SP limit must be
changed first.
4If no key is pressed
for more than 2s, the
displayed value is
set and the display
changes from flash-
ing to continuously
lit.
If the [mode] key is
pressed when the
display is flashing, the
status returns to that of
step 1.
Operation examples

5
For step numbers indicated in red like 4, the following precaution applies:
• If the key lock is set, the numerical value does not flash, and the value cannot be changed.
To change a numerical value, cancel the key lock first.
RUN/READY mode selection
1Start from the opera-
tion display (if neces-
sary press [mode]
once to get the op-
eration display).
2Press and hold [para]
for more than 2s to
get the parameter
setup display. a--M
is shown on the
upper display.
In case of ON/OFF con-
trol, r--r appears on
the upper display.
3Press the [para] key
once. The upper dis-
play says r--r and
the lower display
says rdy (or run).
The current mode is in-
dicated by run for RUN
mode or rdy for READY
mode.
4When [ ] or [ ] is
pressed, the lower
display flashes.
If the DI assignment is
set to "RUN/READY se-
lection," the display does
not flash and no change
can be made.
5When [ ] or [ ] is
pressed, run (or
rdy) on the lower
display flashes.
6If no key is pressed
for more than 2s, the
displayed value is
set and the display
changes from flash-
ing to continuously
lit.
Setup of PID value
1Start from the opera-
tion display (if neces-
sary press [mode]
once to get the op-
eration display).
2Press and hold [para]
for more than 2s to
get the parameter
setup display. a--M
is shown on the
upper display.
3Press [para] repeat-
edly to get p-1 (for
proportional band)
on the upper display.
The value set for p-1
is displayed on the
lower display.
If the control method is
"ON/OFF control," noth-
ing is displayed.
4When [<], [ ] or [ ]
is pressed, the right-
most digit on the
lower display flashes,
and can be changed
to the desired value
for the proportional
band.
In this case, the flash-
ing of the numerical
value implies that it
is not yet set. A nu-
merical setting that
is being changed
flashes the same
way.
The proportional band
can be set in a range
from 0.1 to 999.9%.
5If no key is pressed for more than 2s, the displayed value is
set and the display changes from flashing to continuously
lit.
If the [mode] key is pressed when the display is flashing, the status re-
turns to that of step 1.
Similarly, use i-1 to set the integral time (0 to 9999s), and d-1 to set
the derivative time (0 to 9999s).
Setup of event value
1Start from the opera-
tion display (if neces-
sary press [mode]
once to get the op-
eration display).
2Press and hold [para]
for more than 2s to
get the parameter
setup display. a--M
is shown on the
upper display.
3Press [para] repeat-
edly to get e1on the
upper display. The
lower display says 0.
0on the lower display
indicates that the event
main set value is "zero."
4When [<], [ ] or [ ]
is pressed, the right-
most digit on the
lower display flashes,
and can be changed
to the desired value
for the event.
In this case, the flash-
ing of the numerical
value implies that it
is not yet set.
A numerical set-
ting that is being
changed flashes the
same way.
5If no key is pressed for more than 2s, the displayed value is
set and the display changes from flashing to continuously
lit.
If the [mode] key is pressed when the display is flashing, the status returns
to that of step 1.
Similarly, use e2 to set a value for event 2, and e3 to set a value
for event 3.
6To set hysteresis as
well, press [para]
once (or twice,
depending on the
settings) to display
e1.hy on the upper
display.
The lower display
says 5.
5on the lower display
indicates that the cur-
rent set value for event
hysteresis is 5.
7When [<], [ ] or [ ]
is pressed, the right-
most digit on the
lower display flashes,
and can be changed
to the desired value
for hysteresis.
If no key is pressed
for more than 2s, the
displayed value is
set and the display
changes from flash-
ing to continuously
lit.
Similarly, use e2.hy to set a hysteresis value for event 2, and e3.hy
to set a hysteresis value for event 3.
