Azbil SDC36 - Operation examples

D-4
Setup of PV input range type
1
Press [display] once
to get the operation
display.
If the sensor has not been
wired or is disconnected,
an alarm for abnormal PV
input (any one from
AL0 1
to
AL 1 1
) may appear on
the upper display.
2
Press and hold [para]
for more than 2s to get
the parameter setup
display.
MOde

upper display.
3
Press [ ] or [ ] repeat-
edly, and
Stup

on the upper display.
4
Press [enter].
The current set value
for
C0 1
(PV input
range type) is
displayed.
5
Press [enter].
The rightmost digit on the lower display flashes and its value
can be changed.
Press [<], [ ] or [ ] to change to the desired sensor type in the
PV input range list.
Then press [enter] to finalize your selection.
If the number is flashing, the [enter] key has not yet been
pressed, and the setting has not yet been saved.
Setup of event operation type
In this example, the event 1 operation type is set to deviation high
limit.
1
Press [display] once
to get the operation
display.
2
Press and hold [para]
for more than 2s to get

played on the lower
display.
0

tion type is set to "none."
5
When [enter] is

digit on the lower dis-
play flashes.
Press [ ] or [ ] to get
4
flashing on the display.

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.
1
Press [display] once
to get the operation
display.
2
Press and hold [para]
for more than 2s to get
the parameter setup
display.
MOde
flashes on the
upper display.

on the
upper display and
autO
on the lower

If the control method is
ON/OFF control and if Bit
3 (AT stop/start display) of
the mode display setting
(
C73
) is set to "disabled: 0,"
nothing is displayed.
4
Press [ ] as needed
until
At
and
at.Of
appear on the upper
and lower displays
respectively.
5
When [enter] is
pressed,
at.Of
flashes
on the lower display.
The display flashes only
in RUN and AUTO modes,
and only if there is no PV
problem.
Also, if DI is set to "AT stop/
start", the display does not
flash and the setting can-
not be changed.
6
Press [ ] or [ ] once,
and
at.Of
flashes on
the lower display.
7
If [enter] is pressed,
at.ON
remains steadily lit and AT begins.
During AT, the rightmost decimal point flashes twice repeat-
edly.
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 4 above).
Setup of SP value
1
Press [display] re-
peatedly so that the
orange SP indicator
lights up on the lower
display.
The operation display
now shows the SP.
2
If [enter] is pressed,
the rightmost digit
on the lower display
flashes and numerical
value can be changed.
3
Press [<], [ ] or [ ] to
change to the desired
SP value.
The flashing of the
number indicates that
the setting has not yet
been finalized.
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.
4
If [enter] is pressed,
the displayed value
is set and the display
changes from flashing
to continuously lit.
If the [display] key is
pressed without pressing
[enter] key, the status re-
turns to that of step 1.
