The ATC-900 C9ontroller is a programmable microprocessor-based monitoring device for use on Cat transfer switches. Data access and programming operations are performed using the ATC-900's touch sensitive function buttons in conjunction with an easy-to-read illuminated alphanumeric LED display. Both the functional buttons and the display window are part of the device's door mounted front panel. A built in Help button provides user assistance in the form of message displays.
The communication option permits monitoring and control of several transfer switches, locally or remotely from a single point. Depending on the application, the user can customize the ATC-800 to meet the particular application. The ATC-900 is equipped to display historical information either via the front panel or over mod bus communications to a personal computer. Source 1 and Source 2 run time, available time and connect time are available, as well as load energized time, number of transfers, date, time and reason for the last 16 transfers.
