Pump Size Values • If using feed pumps, do not allow feed pressure to exceed 25% of spray pressure.

For accurate ratios, pump lowers must be same size.

If installing 234024 or 234025, the pump size has not been set in the software. To set pump A and B size and A and B sensor calibration factors, you need Xtreme Mix Data Download software, part no. 246322 for proportioners located in a non-hazardous area, or part no. 246397 for proportioners located in a hazard- ous area.

Calibration values are on pump A and B sen- sors.

Control Box

1.Mount control box (3) to mounting plate (10). FIG. 1.

a.Slide gasket (307) over back of pneumatic con- trol box (3), against lip. Insert box through mounting plate (10).

b.Secure box (3) to plate (10) with 8-32 UNC screws (912).

Size Value Mount box (3) vertically for optimum alternator and component life.

2.Secure mounting plate (10) to cart/stand. Install fas- teners (provided by installer) through six 0.3” (7.62 mm) mounting plate holes.

3.Connect conduit (721) from two sensors (7) to pneu- matic control box (3).

Conduit must be used. Approximately 62” (1575

mm)of cable and conduit provided; do not lengthen.

4.Wire two sensors (7) to control box 18-pin connec- tor. Connect sensor A, then sensor B wires in pairs sequentially – black/green, black/red, black/white – to pins 2-13. See Electrical Schematic, page 16.

5.Connect 18-pin connector to main control board connector (F). FIG. 2.
