SSL & SSR Series
Smart Valve Positioner

Performing Quick Auto-Calibration
Quick Auto Calibration provides a good function that a user can set the valve positioner at the field easily and fast without unlocking its configuration. Please
be advised that this function is limited only to setting of Span and P-Gain.
For setting of other parameters except Span and P-Gain, LOCK should be unlocked first.
- MODE: This is to enter into the main menu.
- ENTER: This is to program the selected main menu.
- UP: This is to move a higher menu from a present menu and to change parameters and setting values.
- DOWN: This is to move a lower menu from a present menu and to change parameters and setting values.
Checkpoints before performing Auto-Calibration
a) Check if any oil, particles, water, and moisture are contained in supply air.
b) Check if the pressure of the air filter regulator is set properly.
c) Check if the operation of the actuator is Direct Acting (DA) or Reverse Acting (RA).
d) Check if the feedback lever or shaft of the positioner is mounted properly.
e) Check if + and – for input and output signals are connected properly.
1. Quick Auto-Calibration
Supply 4…20mA input signal and push MODE for more than 5 seconds.
Time required for this Quick Auto-Calibration process may be different according to the control valves, but it generally takes
about 2~3 minutes. In case of a large-sized actuator, more time is required to wait.
2. Span Adjustment (SPAN)
SPAN can be adjusted after Auto Calibration is completed.

Push DOWN button for more than 5
seconds, and SPAN will be displayed.
Push ENTER button, and 100.0 will be
blinking. Adjust SPAN by pushing UP /
DOWN button.
After SPAN reaches a desired position, push
MODE button two times, and RUN mode will
be performed.
Note) Above 98.5% is just an example to
explain. This value can be different according to
adjustment.
1. Keep pushing UP or DOWN button, and SPAN will be increased or decreased. 0.1% will be increased or decreased by every
pushing.
2.
It is essential to re-adjust SPAN in case of the SSL positioner (linear type). But it is optional in case of the SSR positioner (rotary
type) that operates 90
°
. If necessary, set it as advised above.
In case of a reverse acting type, a counting starts from RA.
