Dual Input, Limit Contact Logic
When configured for Limit Contact Logic, the 702 transmitter will accept the input from two
single pole single throw switches on inputs S1 and S2, and will use limit contact logic for the
determination of the wireless outputs. Please reference Figure 3-7 for details on the wireless
outputs available when using limit contact logic.
