by the (*)-key. All wash prices must be input as cents. For example, a wash price of $4.00
would be entered as (4) (0) (0) (*).
5.1.2 Wash Names
Programming customized wash names uses alphanumeric characters. In this application, the
(#)-key doubles as a space-bar, as well as moves from one letter’s location one place to the
right into the next letter’s location. To begin the process, access the “Wash Setup” menu and
scroll using the 3 -key to select the wash name you wish to change. Refer to Appendix A of
this manual for entering text.
5.2 Wash Interface
Different wash manufactures will require a specific style of output relay pulse in order to
function properly. The “Wash Interface” part of the programming is designed to bridge the
gap of incompatibilities among many different logic controller (PLC) signals, and unit control
signals. Some carwashes require the ability to disable cash upgrades or create just a
momentary pulse, while others would require the ability to hold a wash relay closed.
5.2.1 Relay Stacking
Relay stacking is the ability for Wash Select II
™ to hold back all wash arming signals while
the wash is “In Use”. Most car wash systems will work with or prefer to work with the “Relay
Stacking” set to “YES/Enabled”. Some systems which have bay entry signage built into the
carwash may require the “Relay Stacking” to be set to “No/Disabled”.
Enabled – No arming signals will be sent to the wash if the wash is “In Use” (See
Wash Handshaking). If a customer comes up to the unit and purchases a wash while
another customer is in the wash, the Wash Select II
™ will wait till the wash is not “In
Use”, before sending the second customer‘s wash arming signal.
Disabled – The Wash Select II ™ will send any wash arming signal immediately to the
Carwash regardless of the state of the carwash.
Default Setting is: Yes/Enabled.
5.2.2 Relay Latching
Relay Latching describes the type of relay output for the wash arming signals. Most car
washes prefer the signals to be “No/Pulsed”.
Yes/Latched – Relays are turned on when the arming signal is sent to the carwash.
The relays stay on until either a customer upgrades the wash (if upgrading is
enabled) or the wash becomes “In Use”.
