Relay Logic Table:

Relay 2 can either be a independent relay similar to relay 1 or can be a latching

relay with latch ON. With Latch Off, relay 2 will only respond to the RLY2A

setting. RLY2B will be ignored.

With Latch ON, relay 2 will actuate when RLY2A and RLY2B are in the same

condition. The relay will not change its condition until both inputs reverse their

state.
