Overview
In applications where the Portal will communicate with the Wash Controller, the wash control
wires will need to be connected to the Wash I/O Board.
Most wash manufacturers use a five-wire system to provide the arming signals for the
selected wash packages. One common line and four arming input wires are fed from the
wash’s PLC to the Wash I/O board. Each of the four arming input wires signal the equipment
to give only the designated wash options. When a customer purchases a wash package, the
Portal TI+ sends a signal down the appropriate arming input wire through the Wash I/O
board.
In addition to these five wires, a Wash-In-Use (WIU) Hot and WIU Neutral are required to
reset the wash electronics. Typically, these are also provided by the PLC.
