AL-150 Series

Solenoid Air Valve

General Instructions

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.

INSTALLATION

Inspection

Inspect the carton for damage. If damaged, notify the appropriate carrier immediately. Inspect the device for obvious damage. Return damaged products.

Requirements

•Job wiring diagrams

•Tools (not provided)

•Training: Installer must be a qualified, experienced technician

Caution:

•Disconnect the power supply (line power) before installation to prevent equipment damage.

•Make all connections in accordance with the wiring diagram and in accordance with national and local electrical codes. Use copper conductors only.

•Do not exceed ratings of the device(s).

•Avoid locations where excessive moisture, corrosive fumes, or vibration is present.

MOUNTING

Remote Mounting

N O T E

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.

C A U T I O N

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

CHECKOUT

Go No Go Test

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 are not connected.

MAINTENANCE

Regular maintenance of the total system is recommended to assure sustained optimum performance.

FIELD REPAIR

None. Replace with a functional solenoid.
