0004
Hunting does not subside.
-The size of actuator is small.
-Inside of the piping is choked (with
something such as a speed
controller).
-Stop hunting with the PID constant
setting (parameter code: 800) .
See “■Improved Controllability”.
0005
Impossible to check the
balance current
Simple balance adjustment
(parameter code: C20） has not
been performed.
-Recalibrate the positioner
(parameter code: 30) after
performing a simple balance
adjustment (parameter code: C20).
-If the set value of the dead band
(parameter code: 600) is
changed, return the set value to 0.
0006
Input current adjustment error
(4mA DC)
-Input current deviates widely from
4mA DC.
-Check that the Input current
is 4mA DC.
0007
Input current adjustment error
(20mA DC)
-Input current deviates widely from
20mA DC.
-Ensure that the input current
is 20mA DC.
