Hold down [PARA]
for 2 s or longer. The
screen for specifying
parameters is shown

Execution of auto tuning (AT)
AT forces ON/OFF of the MV a number of times (a limit cycle) to calculate
PID values. Check that this operation does not create any problems for the
associated equipment before executing AT.

Press [MODE]
once to show the
operation display.

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 constants. AT can also be stopped by changing the
setting from
At.ON
to
At.OF
(return to step 3 above).
Setup of the SP
1
Press [MODE]

to the desired SP by
pressing [

Flashing means the
setting has not been
finalized.
If the SP limit function
is enabled, a value
exceeding the limit
cannot be set. If you need
to change the value,
change the SP limit first.
