(1) Connect power. Any values between 4 to 20mA (DC) can be used for power. After
connecting power 'READY 6, 5, 4, 3, 2, 1' message is appeared in order on LCD, which
means preparing time to operate PCB circuit and parts. The following message is
displayed in 6 seconds.
Push <ENTER> for 6 seconds at
RUN
mode and
AUTO CAL
message is appeared.
(2) Push <ENTER> and then
AUTO1
mode is started.
(3) Push <DOWN> and
AUTO2
mode is displayed.
(4) Push <ENTER> at
AUTO2
mode. Auto 2 calibration is started and the next modes
are displayed in order on LCD. Normally it takes 3-5 minutes for auto calibration in
AUTO2
mode but it can be different by actuator's volume.
(4) When Auto calibration is done, '
COMPLETE
' message is appeared on LCD. After 4
seconds the procedure is returned to
RUN
mode and valve stroke by current input signal
is displayed as percentage.
(5) Zero, Span, PID parameters and RA/DA are automatically set when Auto 2 calibration
is completed.

Auto calibration (AUTO CAL)
The calibration of YT-2300 is simply performed by Auto calibration and there are 5 types
of Auto calibration as AUTO1, AUTO2, AUTO3, BIAS, V_0.
AUTO1 calibration is useful for users' in the field and AUTO2 calibration is for
valve company or initial parameters setting of YT-2300.

It takes about 2-3 minutes for auto calibration and it can be different by actuator's
volume. AUTO1, AUTO2 and AUTO3 calibration set RA/DA automatically.
Auto calibration types
Auto 1 calibration (AUTO1)
At this mode all parameters necessary to valve operation are set except KP, KI, KD. It is
used to re-execute calibration by users in the field after being supplied YT-2300 whose
parameters were all set by valve company.
(1) Push <ENTER> for 6 seconds at
RUN
mode and
AUTO CAL
message is appeared.
(2) Push <ENTER> and then
AUTO1
mode is displayed.
(3) Push <ENTER> again at
AUTO1
mode and Auto1 calibration is started.
(4) When Auto calibration is done, '
COMPLETE
' message is appeared on LCD. After 4
seconds the procedure is returned to
RUN
mode and valve stroke by current input signal
is displayed as percentage.
