Limit Switch Setting Instructions

Section 4: Limit Switch Setting Instructions

4.1

Before making limit switch setting

1.

Move valve to mid-position (use handwheel).

2.

Phase the power (motor) voltage and make sure that open contactor moves valve
Open and close contactor moves valve Closed.

DANGER

Improper power voltage phasing eliminates protection of both position limit switch and
torque switches, risking valve damage.

4.2

To set Open Limit Switch (LSO)

1.

Open valve during handwheel operation note rotation direction of screwdriver
(Fig. 6) in LSO Adjusting Shaft. After valve is fully Open, Close it three handwheel
turns to allow for coasting when motor is actuated.
