Installation

0.135 in. (3.4 mm)

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.

Connect one lead wire to Pin 26 on the variable frequency drive (VFD).

Connect the other lead wire to Pin 21. See VFD manual 311596 for specific wiring details.

Operation

The kit supplies higher pressure air to the BPR for normal production conditions, or lower pressure air for off production times. The off production state reduces energy use, paint shear, and pump/system wear during down times.

The solenoid (0.50 W, 24 Vdc, .020 A) is actuated or deactuated by a 24 Vdc input/output signal from the VFD. 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, slowing down the system.
