Installation

Do not install equipment approved only for non-haz­ardous locations in a hazardous area.

See the illustration on page 1. The 15K012 Kit is a preassembled module
which is not intended for use in a hazardous location. Install the kit in a
non-hazardous area only. Mount the panel vertically to protect components
from accumulation of air line contaminants and condensation. See the
mounting hole detail.

Connect a 5/32 in. (4 mm) OD air supply line to the air inlet elbow. Plumb
another 5/32 in. (4 mm) OD air line between the Outlet to BPR port and the
back pressure regulator (BPR), which is located in the hazardous area.

Graco VFD: Connect one lead wire to Pin 26 on the VFD. Connect the other
lead wire to Pin 21. See VFD manual 311596 for specific wiring details.

Graco ACS: Connect one lead wire to +24 Vdc power supply. Connect sec­ond lead to Terminal 18 of the ACS module. Connect Terminal 17 of ACS to
24 Vdc common of the power supply. See ACS manual 3A0006 for specific wiring details.

Operation

Adjust the air pressure regulator to provide desired system pressures in each operating mode. The kit supplies
higher pressure air to the BPR in normal production mode, or lower pressure air in off production mode. The off pro­duction mode reduces energy use, paint shear, and pump/system wear during down times.

The kit allows operation with either solenoid activated or solenoid not activated in production mode. The solenoid
(0.50 W, 24 Vdc, .020 A) is actuated or deactuated by a 24 Vdc input/output signal from the VFD or ACS. When actu­ated, the solenoid supplies higher air pressure to the BPR to support production requirements. When the solenoid is
not actuated, lower air pressure is supplied to the BPR, reducing the system pressure maintained by the BPR.
