the input:
Step 1: The make contact S3 is interconnected in series to output Q1 and to a further circuit element. A
series connection corresponds with the AND block:
Step 2: S1 and S2 are connected in parallel. A parallel circuit corresponds with the OR block:
Unused inputs
Keep NULL connection for the unused connectors.
In our example we shall use only two inputs of the OR block and two inputs of the AND block; the relevant
unused first and fourth inputs have no connection.
Wiring
Connect the switches S1 to S3 to the screw terminals of your xLogic:
● S1 to connector I1 of xLogic
● S2 to connector I2 of xLogic
● S3 to connector I3 of xLogic
The output of the AND block controls the relay at output Q1. The load E1 is connected to output Q1.
Wiring example
The following figure shows you the wiring, based on a 220 V AC version of xLogic.
