The Enter Wash and Code Accepted/Wait relays are intended to
control customer guidance lights. The status of the relays can be
determined by the LEDs that are located on the board (see the
wiring diagram in the back of this manual).
Note:
9.7 "Enter Wash" Signal Does Not Work
The "Enter Wash" feature produces a relay contact closure when any wash
program is activated (either by a valid customer code or cash). This relay stays
on until the wash "In-Use" signal turns on for that customer. In many
circumstances the "Enter Wash" signal for customer lights is generated by the
car wash equipment. If the carwash equipment generates the "Enter Wash"
control signal, check the carwash equipment.
If the interface board "Enter Wash" signal is used, perform the "Enter Wash"
relay test described in the Interface Test section. If the relay fails, replace the
interface board.
