■Check Code List

Table 17 shows check codes detected during positioner calibration. When hunting is detected
during calibration, it automatically performs PID constant adjustment, subsides hunting and checks
the balance current. If a check code is detected after the calibration, check it in accordance with the
following countermeasures.

-Switch to auto mode, change the input
current, and confirm that the actuator is
hunting. If hunting is occurring, stop it
with a PID adjustment (parameter code:
800). See "■Improved Controllability".

Countermeasure
-Adjust the balance adjusting screw
to correct the balance current (See
Fig. 19).
-Stop hunting with the PID constant
setting (parameter code: 800) .

-Recalibrate the positioner
(parameter code: 30)
performing a simple balance
adjustment (parameter code: C20).
If the set value of the dead band

changed, return the set value to 0.
-Check that the Input current
is 4mA DC.
-Ensure that the input current
is 20mA DC.
