McCain ATC eX NEMA Controller – User Manual 17
Version 1.0
3 CONFIGURATIONS
The ATC eX NEMA controller can be configured depending on the application. In order to properly
configure the controller follow the below directions.
3.1 TS2 Type 1
This is the default configuration for the controller; it uses an SDLC port to communicate to the Bus
Interface Units. The A2 connector in the front panel is used to provide the AC lines (Hot and neutral) and
the chassis ground, also the fault monitor signal and logic ground are provided; connect the AC harness
to the AC INPUT header located on the Control Signals board (M66450A) and the chassis ground wire
(green wire) is attached to the chassis stud located on the bottom of the controller’s chassis.
TS2 Type 1 configuration must be defined through the traffic application running into the controller.
3.2 TS2 Type 2
This configuration is used to handle the round MilSpec connectors of the TS1 standard with the TS2
functionality. A connector box must be attached to the controller by using 4 screws and 4 washers to
mechanically fix them together; then the electrical connections are as follow: the AC harness is connected
to the AC INPUT header and the DC harness is connected to the CONN BOX header, both are located
on the Control Signals board (M66450A); the Fault Monitor and Voltage Monitor signals are routed
through the FM/VM harness which is connected to the P10 header and the ribbon cable is connected to
P9 header, both two located on the Host board (M69945A). The chassis ground wire (green wire) is
connected on the chassis stud located at the bottom of the controller chassis.
TS2 Type 2 configuration must be defined through the traffic application running into the controller.
Note: The next two connector boxes are available, McCain option and Traconex compatible option; in the
future more connector boxes options will be supported according to customers’ needs.
