Section 2: Hardware Description
2.1 General
The purpose of this section is to familiarize the reader with the
ATC-100 hardware, its nomenclature, and to list the unit’s specifi-
cations.
2.2 Front (Operator) Panel
The front panel, depending on the installation, is normally accessi-
ble from the outside of a panel or door. The front panel provides a
means to:
• alert the user to specific conditions;
• perform an Engine Start;
• perform a System Test; and
• program a Generator Test.
The ATC-100 front panel serves two primary functions: output
and input (see Figure 1). The output function consists of five LED
outputs:
1. Unit Status;
2. Utility Available;
3. Utility Connected;
4. Generator Available; and
5. Generator Connected.
There are three input functions accessible through the pushbut-
tons:
1. Engine Start;
2. Set Generator Test; and
3. System Test.
