Wiring Diagram
The following diagram shows how to wire the treadle switch for the
EMS into the Relay Box.
Important Note:
This circuit is used if the customer has purchased a treadle switch from
the equipment vendor. The Entrance Management System in the
Tunnel Master Junior allows a roller to be fired automatically upon
seeing a second 24Volt input on Input 10. At the same time, an output
can be set to fire and the roller can be delayed.
When a car enters the tunnel the TMJ 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 TMJ 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.
