Typical example

Energize to Run

(1) Solenoid

Voltage ... 24 to 32 VDC

Coil resistance at 25°C ... 37.8 to 46.2 Ohms

(2) Bolt

Torque ... 10 ± 1 N·m (7 ± 1 lb ft)

(3) Locknut

Torque ... 61 to 75 N·m (45 to 55 lb ft)

Use the following method to adjust the plunger:

1. Hold housing (5) against gasket (7) on a flat surface.

2. Turn setscrew (4) clockwise until the setscrew contacts lever (6).

3. Turn setscrew (4) counterclockwise by 90 degrees.

4. Energize solenoid (1). Turn the solenoid clockwise until the solenoid stops. De-energize the solenoid. Turn the solenoid clockwise by an additional 90 degrees.

5. Tighten the locknut.

Energize to Shutdown

(1) Solenoid

Voltage ... 24 to 32 VDC

Coil resistance at 25°C ... 40.2 to 49.2 Ohms

(2) Bolt

Torque ... 10 ± 1 N·m (7 ± 1 lb ft)

(3) Locknut

Torque ... 61 to 75 N·m (45 to 55 lb ft)

Use the following method to adjust the plunger:

1. Hold housing (5) against gasket (7) on a flat surface.

2. Turn setscrew (4) clockwise until the setscrew contacts lever (6).

3. Turn setscrew (4) counterclockwise by 90 degrees.

4. Turn the solenoid clockwise until the solenoid stops. Turn the solenoid counterclockwise by one complete turn.

5. Tighten the locknut.
