Air Comp.Duplex W/Auto Alternation Diagram | Mike Holt's Forum

I'm looking for a wiring diagram for an existing, old Furnace MCC with double throw single pole relay to alternate 2 air compressors. Each compressor has its own pressure switch, all the control circuit is fed from one source. The starters have 1 nc & 2 no aux contacts.

When the Control Switch closes again, it energizes LOAD 2. When the Control Switch opens, LOAD 2 is turned off, the Alternating Relay toggles back to the LOAD 1 position, the red LED marked "LOAD 1" is ON, and the process can be repeated. Figure A. A DPDT Alternating Relay is the same as a SPDT but with an extra set of NO & NC contacts.

alternator relay and 1st air compressor. 2. The pressure rises, opening the lead pressure switch, de-energizing the alternator relay and the 1st air compressor. 3. The alternator will then alternate from the 1st air compressor to the 2nd air compressor, ready for the next need for compressed air. 4. The next phase is the same as Steps 1-3, except

The Furnas Brand Class 5247 alternator relay provides a means of automatically alternating the operation of two separately mounted motor driven pumps or compressors. This alternating action assures even readiness and wear on both pumps. The Class 5247 alternator is of industrial design specifically for use in pump and compressor applications.

Alternating Relays. Bulletin 700-HTA Alternating Relays serve as interposing relays between your controller and field devices. The alternating feature lets you select the primary or secondary load or to alternate between the two. You can use these relays in applications with pumps, compressors, air conditioning, and refrigeration units.
