2.8.5 Wash Handshaking
The Wash Select II supports two types of “Wash-In-Use” handshaking.
1. Wash-In-Use: The car wash activates the wash-in-use signal for the entire time
the car wash is in use. (Voltage present)
2. Cycle complete: The “Wash-In-Use” is normally on (voltage present). When it is
given a “wash is completed” signal (no voltage present), the car wash will
deactivate the “Wash-In-Use” signal for about two seconds and it will be
reactivated. When using the “Cycle Complete” mode, “Upgrades” will be disabled
and “Forced Selection” will be enabled. If your car wash supports the “Wash-In-
Use” method, you should not use the “Cycle Complete”.

Note:
The Wash Select II supports a 24V – 120V AC or DC “Wash-In-Use signal. No internal
changes need be made for either voltage.
