In a transaction where the customer enters a code, the wash will arm the same as in Auto by
Price. No selection will be required unless the customer tries to buy up with $5 or more.
6.2 Customer Stacking
Important: This feature is not supported by all configurations.
If Customer Stacking is supported it will appear on your system configuration report as
“Customer Stacking: Enabled”
If Customer Stacking is not supported it may appear on your system configuration report as
“Wash in use Lockout: Enabled”
Customer stacking allows a second customer to be processed at the entrance of the carwash
while the previous customer is in the carwash. Permitting customers to enter their code and/or
cash while waiting for the customer ahead of them increases the throughput of the wash.
Once the second customer enters a valid code (or deposits enough cash to purchase a wash),
the "Code Accepted/Wait" relay will close until the wash in-use signal turns off. When the wash
in-use signal turns off, the "Code Accepted/Wait" relay will open and the "Enter Wash" relay will
close until the wash in-use signal turns on again (indicating that the second customer has
entered the wash).
All systems allow a second customer to be processed while the previous customer is in the
carwash. The relay stacking section of the SYSTEM CONFIGURATION indicates if the function
relays will be closed as soon as a valid code is entered (relay stacking disabled) or if the function
relays will wait until wash in-use turns off (relay stacking enabled).
