There are three basic types of wiring diagrams used in the hvac r industry today which are. Mars hvac potential relays mars series relays are manufactured for the hvac industry. Rbm 90 63 potential relay continuous coil voltage 170 pick up minimum 140 maximum 153 drop out maximum 65 90 64 potential relay continuous coil voltage 395 pick up minimum 245 maximum 275 drop out maximum 140 90 65 potential relay continuous coil.
Each part should be set and connected with different parts in particular way.
The universal potential motor starting relay wiring diagram and cross reference. Each part should be set and connected with different parts in particular way. There is never a path between 2 3 or 5 6 because between them at least one of them is always open. 1 to 2 and 4 to 5 are closed normally closed with no power and they open when the coil is energized.
