3.6.3 Wiring the Wash-In-Use Interface
Note: Follow local electrical code when wiring the Sentinel.
Wash equipment requires a reset circuit. This circuit is generally identified as the “Wash-In-Use” (WIU)
signal. It is not uncommon for values of this voltage to be as much as 115-120 VAC, so it is extremely
important to verify that there is no power applied to any of the wash components before proceeding.
