2.6.2.8 Install the Air Control Valve (Pneumatic Masts Only)

Operation of a pneumatic mast requires an Air Control Valve (Figure 2-20). The Air Control
Valve is used to stop the mast from extending in the event of an electric or magnetic field. The
Air Control Valve may be customer-provided or purchased separately through The Will-Burt
Company. This section describes installation of the Will-Burt Air Control Valve Kit (P/N:
915530). For Air Control Valves not supplied by Will-Burt, the customer is responsible for
making the correct wire connections.
Note: A Check Valve must be placed between the Air Supply and the Air Control Valve. A
Check Valve is supplied with all Will-Burt compressor systems.

The Air Control Valve is comprised of two valves plumbed together. Each valve coil has two
black wires. During installation, polarity is of no concern for the black wires from each valve coil.
To install the Air Control Valve (Figure 2-21):
1. Connect one of the black wires from each valve coil together.
2. Secure the connected black wires to the DB9 Terminal Block where the red wire from
DB9 connects. This is where the battery positive cable from system power will eventually
connect.
3. Secure the remaining wire from the Up Air Valve Coil to the DB9 Terminal Block where
the orange wire from DB9 connects.
4. Secure the remaining wire from the Down Air Valve Coil to the DB9 Terminal Block
where the yellow wire from DB9 connects.
