3.7.3 Wiring the Wash-In-Use Interface

Note:

Follow local electrical code when wiring the Portal TI.

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.

Note:

Wash equipment wiring may vary, and not all equipment manufacturers use the wash-
fault interface. Refer to the manufacturer’s documentation for additional information.

• Make sure all power is disconnected from the wash equipment prior to beginning this

procedure.
