TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 Figure 12-2. Actuator Test Circuit shaft towards maximum fuel and counterclockwise to move it towards minimum fuel. (8) Set test circuit to CENTER. Observe and note direction and position of terminal shaft movement. (a) If terminal shaft moves to another position set test circuit to OFF. 1. For a clockwise movement turn pilot valve plunger screw (63) slightly counterclockwise. 2. For a counterclockwise movement turn screw (63) slightly counterclockwise. 3. Note the new position for reference in case more adjustment is needed. 4. Repeat steps 8(a)1. and 3. or 8 (a) 2. and 3. until no movement of the terminal shaft occurs when the test circuit is moved from OFF to ENTER. Continue on to step (9) and calibrate terminal shaft. (b) If terminal shaft did not move from its original position, the pilot valve plunger is centered. Continue to step (9) and calibrate terminal shaft. (9) Turn test circuit to OFF and set potentiometer to zero ma. CAUTION Do not exceed 200 ma during remainder of test to prevent damage to the magnetic properties of the magnet. (10) Set test circuit switch to NORMAL. (11) Adjust potentiometer to 20 ma. (12) Turn spring seat (56) counterclockwise until actuator terminal shaft 12-3
