Jr. System Hardware and Installation

ENTRANCE MANAGEMENT SYSTEM WIRING
When a car enters the tunnel, the User Manual will wait to see two signals
within 15 seconds of each other from the tire treadle that is wired into Input
10. The first signal represents the front tire, and the second signal represents
the rear. Once it
sees the second signal, the Tunnel Master
Jr. will fire an
optional sign relay followed by a roller relay. The amount of time between
the sign firing and the roller is called the Entrance Management Delay in
the Wash Settings.The following diagram shows how to wire the treadle
switch for
the EMS into the Relay Box.
!
IMPORTANT: This circuit is used if the customer has
purchased a treadle switch from the equipment vendor. The
Entrance Management System in the Tunnel Master
Jr.
allows a roller to be fired automatically upon seeing a
second 24V input on Input 10. At the same time , an output
can be set to fire and the roller
can be delayed.
