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.
