No/Pulsed – Relays are turned on for a 2 second pulse when the arming signal is
sent to the carwash. The relays will not activate again unless the customer upgrades
the wash (if upgrading is enabled).
Default Setting is: No/Pulsed
5.2.3 Relay Pattern
The Wash Select II is equipped to allow up to 8 relays to be used for programming of wash
packages. The default pattern of 1 output for each wash is the standard setting for most
carwashes, and most manufacturers do not require this pattern to change. If you wish to
change this pattern, refer to the Wash Select II
™ Operations Manual for more information.
5.2.4 Auto Out of Service Detect
Note: The wash will remain out of service for as long as the signal is held high.
Certain wash manufacturers will include a feature that allows the unit to know when the wash
is experiencing trouble, or has gone out of service. This feature will utilize the wash-in-use
signal to initiate a series of timed pulses, which we will decipher, and then use to prevent any
further transactions from occurring. This is known as “Automatic out of Service Detection”. To
program the Wash Select II to accept this message, place the main board in “Setup Mode”
and open the “Wash Interface” menu. The “Auto out of Service” is shown there. The installer
should choose to enable this feature. Refer to the diagram below to view the pattern
associated with the out of service routine.
