UTO/MANUAL conversion screw’s cleaning

- If the air pressure value of the regulator is output as OUT1 regardless of the supply pressure

input signal, the hole of the auto/manual switching screw located on the pilot valve is clogged
by foreign substances such as dirt and oil, so it must be cleaned.

- Loosen the lock screw on the upper part of the pilot valve, remove the auto/manual switching

screw, make a hole with a steel wire of 0.3mm or less, wash it, and assemble it again.

7. Error Check and solution method

7-1 Basic check point when positioner does not operate

-. Supply pressure check point : Over Min 1.4 kgf/cm

-. Input signal check : 4~20mA

-. Check ZERO, SPAN adjustment status.

-. Check whether air comes out well from the nozzle of the torque motor

-. Check Feedback lever installation status.
