The following can be performed: angle check for a feedback lever
(AnGL), balance current adjustment (0AdJ), automatic calibration
(CAL), input current adjustment (S-0) & (S-F), confirmation of
balance current (bAL), span adjustment (SPn), and initialize of
parameter (dFLt).
(C10) Angle check
Confirm rotation angle of the feedback lever. Referring to the LCD
indication, the fully-closed position / fully-open position of an
actuator should be adjusted to be between +/-5
o
to +/-15
o
.
(C20) Simple balance current adjustment
Balance current for a torque motor can be adjusted. After rotating
a balance adjustment screw until a pressure gauge for OUT 1
indicates 0MPa, rotate the adjustment screw until pressure starts
increasing again, or the actuator starts operating.
(C30) Calibration
A fully-closed position and a fully-open position of a mechanical
valve can be automatically adjusted
*16
. Also, PID constant can be
automatically set
*17
.
(C40) & (C50) Input current adjustment
Input current of 4mADC and 20mADC can be calibrated. Confirm
the input value (S value) in the auto mode, and adjust it if
4mADC=0 and 20mADC=100 cannot be achieved. This
adjustment is not necessary in general.
(C60) Confirmation of balance current
Adjustment of balance current can be confirmed. If adjustment is
good (Good), the balance current is adjusted correctly. If
adjustment is high (HI) or low (Lo), the balance current needs to
be adjusted again.
