* = This input is only necessary to establish output on J1/2. after the output J1/2 is established input J8/8 is not a necessity.
# = J1/10 output is cut with a momentary lift input and reset with a J1/2 input, or recycling power.
& = 7.5V signal which is level input from sensors.
(1)-) = This input is only necessary to establish this output, after the output is established the input is not necessary.
