Overview

Air Control Module 26A231 provides electrical and air

connections to enable a ProMix PD2k Dual Panel pro-

portioner to operate two manual spray devices, as well

as, one or two gun flush boxes, or one or two air shutoff

valves. See FIG. 1 for the identification label.

Order Gun Flush Box Kit(s) 15V826 separately (see the

Gun Flush Box Kit manual). Each 15V826 Kit includes

one gun flush box and related parts. The pressure

switch included in Gun Flush Box Kit 15V826 will be

installed in this interface module.

Order Air Shutoff Kit(s) 15V823 separately (see the Gun

Air Shutoff Kit manual). Each 15V823 kit includes one

air cutoff valve and related parts.

Installation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever

you see this symbol.

1. Relieve pressure from the air inlet supply before

connecting air to inlet (13) of the enclosure. See

Parts on page 8.

2. Follow the Pressure Relief Procedure in the applica-

ble manuals. See Related Manuals, page 2.

Location

Install the air control module enclosure (1) within 15 ft

(4.5 m) of the PD2K Dual Panel Control Enclosure, to

ensure that the cable (23) will reach between the two

enclosures.

Mount the Enclosure

1. See Dimensions, page 9.

2. Ensure that the wall and mounting hardware are

strong enough to support the weight of the equip-

ment, fluid, hoses, and stress caused during opera-

tion.

Using the equipment as a template, mark the mounting

holes on the wall at a convenient height for the operator

and so equipment is easily accessible for maintenance.

3. Drill mounting holes in the wall. Install anchors as

needed.

4. Bolt equipment securely.

The equipment mush be grounded to reduce the risk

of static sparking. Static sparking can cause fumes to

ignite or explode. Grounding provides an escape wire

for the electric current.

This equipment stays pressurized until pressure is

manually relieved. To help prevent serious injury from

pressurized fluid, such as skin injection or splashing

fluid, follow the Pressure Relief Procedure when

you stop spraying and before cleaning, checking, or

servicing the equipment. When turned off, all air

valves bleed to atmosphere.

Installation

Install the Cable

1. Loosen the captive screws and remove the front

cover from the enclosure.

2. The cable (23) has bare wires at both ends. Thread

the shortest end (4 in. [102 mm]) into the enclosure

through the strain relief bushing (7). See FIG. 2.

3. Connect the cable wires to the left side of the termi-

nal strip (12), as indicated by the label (37). See

FIG. 2 and Table 1.

4. Connect the other end of the cable (5 in. [127 mm])

to the appropriate terminal blocks of the EFCM in

the PD2K Dual Panel Control Enclosure. See FIG. 3

and Table 2.

Install the Pressure Switch

NOTE: The Air Control Module Kit does not include a

pressure switch (PS). The pressure switch is supplied

with the gun flush box kit. Install the pressure switch in

the interface module as follows.

1. Each gun flush box kit includes one pressure switch

(PS). The Air Control module can accommodate 1

or 2 pressure switches. Install the switch(es) in the

left side of the enclosure. See FIG. 4.

2. Connect the wires from PS#1 to the right side of the

terminal strip (12) pins 5 (+) & 6 (-), as indicated by

the label (38). See FIG. 5 and Table 1.

3. If using a second gun flush box, connect the wires

from PS#2 to the right side of the terminal strip (12)

pins 7 (+) & 8 (-), as indicated by the label (38). See

FIG. 5 and Table 1.

Connect the Gun Flush Box

NOTE: Use 5/32 in. (4 mm) OD tubing to connect the

gun flush box air ports to the interface module air ports,

as follows. See FIG. 7.

1. From the Pport to the air supply.

2. From the A port to the pressure switch air input.

3. From the C port to the gun flush box solenoid out-

put.

4. From the S port to the atomizing air safety shutoff

valve pilot port. See the gun flush box manual for

details on the safety shutoff valve.

5. From the AFS to the atomizing air safety shutoff

valve IN port. See the gun flush box manual for

details on the safety shutoff valve.

Connect Air Supply to Module

Connect a 1/4 in. (6 mm) OD tube between a clean, dry

air supply (filtered to 10 microns) and the module air

inlet fitting (13). See Parts on page 8.

Replace the Cover

Reinstall the cover on the enclosure and secure with the

four captive screws.

Ground the Enclosure

Connect a ground wire (Y) from the enclosure’s ground

screw (6) to a true earth ground. See FIG. 6.
