The ATC-800 Controller is a programmable microprocessor-based monitoring device for use on Cat transfer switches. Data access and programming operations are performed using the ATC-800'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-800 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.

Factory programming will load all standard features and customer-specified options per the default settings.
In-phase monitor is a feature that will allow a transfer between two sources only when the phase difference between the two sources is near zero. This is an open transition transfer that prevents in-rush currents from exceeding normal starting currents in the case where motor loads are being transferred.
Load voltage decay transfer is a feature that, after opening the switch for the original source, holds in the neutral position until the voltage on the load is less than 30% of rated voltage. This operation is an open transition that prevents in-rush currents from exceeding normal starting currents in the case where motor loads are being transferred.
