A/H-ARC PANEL PIPING DIAGRAM

 
Foot-Operated Air Treadle Valve
 

Mount the panel on a rigid vertical support, low enough for the 1/2" air line from the compressor to slope down to the air reservoir. This permits moisture to drain into the reservoir where it can be automatically ejected by the moisture valve.   Pipe and wire the panel into the system per applicable connection diagrams. When complete, turn power ON. Check preset air pressures. Compressor supply pressure at gauge A must range from 65-80 psi. This pressure is controlled by 1PS N.C. pressure switch. Low pressure alarm should	sound below 50 psi. This is controlled by 2PS N.C. pressure switch. If reservoir pressure drops below 40 psi, the relay emergency valve applies system pressure.   Special Bleeding Instructions for A/H Systems Fill fluid reservoir/bleeder(s) and pressure cluster(s). Hold BPB bleeder pushbutton in and stroke pressure cluster by repeatedly pushing Bleeding Control Valve.

J57159 AIR TREADLE VALVE INSTALLATION The air treadle valve may be located in front or to either side of the standing or seated operator, but it is essential that the foot pad be in a position convenient for the operator to control the full stroke to provide the "feel" of the brake torque developed. Bolt the bracket to the floor using 3/8" bolts. Install air hoses in reservoir and delivery ports. All other common ports must be plugged.   Pipe reservoir and delivery lines to the air relay valve on panel using 3/8" tubing provided. Install supply pressure gauge in cab.

LOW AIR PRESSURE ALARM INSTALLATION 115VAC - J34778 230VDC - J24673         Mount alarm in cab. Make connections to panel per wiring diagram.
