2.8.4 Enable Automatic Out-Of-Service Detection
If the car wash goes down, the Wash Select II can be informed to let customers know that the
wash is down. The Wash Select II supports the detection of an Out-of-Service condition on
the Wash-in-Use input. This method is supported by many, but not all, car wash systems.
If the Automatic Out-Of-Service detection is enabled, and the car wash goes down, the
wash’s Wash-in-Use signal should do the following:

Turn off for at least one second.

Turn on for one second. (+/- 1/8 second tolerance)

Turn off for one second. (+/- 1/8 second tolerance)

Turn on for the duration of the out-of-service condition.

Turn off when the car wash is back in service.
If the Wash Select II goes Out of Service while it contains credit in escrow, a voucher will
be printed for the customer.
To enable the “Automatic Out-Of-Service detection, follow the steps below.
