Schneider Electric AL-150 Series Catalog Page

Application

For applications where an electrical circuit is used to control
a pneumatically operated device. Used to direct supply air to
a pneumatic device when the coil is energized or de­energized depending on the supply and exhaust air connects.

Features

• Brass body provides long life.

• High capacity of AL-150 series allows more devices to be

used with fewer solenoid air valves.

Remote Mounting

This method requires the use of the enclosure on the coil. An integral mounting plate is
provided.

1. Fasten to wall or duct with two #8 sheet metal screws or equivalent.

2. Rotate the soleniod enclosure to position the wiring compartment, if necessary.

Inside Cabinet Mounting

1. Fasten to subpanel of cabinet with two #8 sheet metal screws.

2. Remove red cap.

3. Remove name plate by sliding out of coil.

4. Remove coil.

5. Install plunger tube through hole in electrical enclosure.

6. Re-install coil and coil hold down name plate snap red cap back on solenoid.

Do not over-tighten as this may cause distortion of plunger tube or damage coil.

1. Connect solenoid ports.

2. Apply air to Port #1, Ports #1 and #3 should be connected.

3. Apply power to the solenoid, Ports #1 and #2 should be connected.

4. If Ports #1 and #2 are not connected, check to see if the proper voltage is applied.

5. Replace the solenoid with a functional unit if solenoid is powered and Ports #1 and #2
ar

e not conn

ected.
