NOTE:
ACTUATOR SHIPPED IN OPEN
POSITION, 20mA REPRESENTS OPEN
POSITION. DO NOT ADJUST FEEDBACK
POTENTIOMETER OR LIMIT SWITCHES
THEY ARE FACTORY SET AND DO NOT
REQUIRE CALIBRATION. TO
CALIBRATE THE OPEN AND CLOSE
POSITION, USE THE ZERO (4mA) AND
SPAN (20mA) TRIM POTENTIOMETERS.
TO CALIBRATE, OPERATE ACTUATOR
TO CLOSE POSITION AND ADJUST WITH
ZERO TRIM POT THEN OPERATE TO
OPEN POSITION AND SET USING SPAN
TRIM POT. NO FURTHER CALIBRATION IS
NECESSARY.
