Document Title: EZ Trak Installation and Operations Manual
1 Introduction
The EZ Trak fleet terminal is a drive-up entry system developed specifically for the
automobile dealer market. EZ Trak cards and codes allow the dealer to track all wash use by
driver and department. EZ Trak can be used to track car wash use by rental companies,
neighboring dealerships and businesses.
EZ Trak is designed to integrate with the dealer’s local computer network. It requires 24 Volt
AC or DC power, Intranet (Ethernet) connection, and a web browser.
1.1 Electrical Planning
1.1.1 Electrical Requirements of the EZ Trak
The EZ Trak requires 24 VAC 1-amp service, which should be provided during wash
construction. Most installers will have power supplied directly from one of the three phases
used to power the wash motors and controllers. If this method is used, special attention
should be given to proper earth grounding at the unit, as well as in the breaker panel.
Make sure that the protective earth ground wire does not carry any motor return current. Only
the neutral wire should carry return current.
The EZ Trak activates one wash type. The car wash’s Programmable Logic Controller (PLC)
activation voltage is routed to the EZ Trak interface board and back to the car wash
controller. In addition, a Wash-In-Use Hot and Wash-In-Use Neutral are required to properly
activate the EZ Trak operator interface and maintain accurate accounting information.
Typically, these are also provided by the PLC. It is important to consider this fact when
planning the conduit runs, because there will need to be 2 separate runs from the wash to the
EZ Trak—one for AC power, and one for PLC Control Wires and the Ethernet cable. The
base of the EZ Trak terminal provides two knock-outs as well as the hole in the units' base to
accommodate various conduit installation options.
An Ethernet cable is required to program the EZ Trak. This cable should be standard CAT 5
or CAT 6. This cable can be pulled with the control wires. The cable is connected to the
Dealer’s Ethernet switch or router.
