Instructions for Installation, Operation and Maintenance of the
Eaton ATC-600 Automatic Transfer Switch Controller
Section 2: Hardware Description
2.1 General
The purpose of this section is to familiarize the reader with ATC-
600 hardware, its nomenclature, and to list the unit’s specifica-
tions. The information presented is divided into the following four
parts:
•
Operator Panel
•
Rear Access Area
•
External Hardware
•
Specification Summary
2.2 Operator Panel
The operator panel, which is normally accessible from the outside
of a panel or door, provides a means for:
•
Being alerted to specific conditions
•
Receiving functional help
•
Programming
•
Parameter Monitoring/Selection/Metering
LEDs, a display window, pushbuttons, and a mimic bus make up
the front accessible operator panel (Figure
1
).
Seventeen individual LEDs are lit when performing or indicating a
specific function. For detailed information on individual LEDs refer
to Paragraph 3.2.
The LED type display window is used to display all ATC-600 mon-
itored parameters, setpoints and messages in easy to read for-
mats. The alpha numeric display is approximately 0.75 by 4.25
inches and is able to display up to eight characters at a time. For
details concerning the kind of information that can be viewed in
the display window refer to Paragraph 3.3.
The front operator panel supports six long-life membrane pushbut-
tons. Pushbuttons accomplish their function when pressed and
released. Refer to Paragraph 3.4 for information concerning the
function of specific pushbuttons.
2.3 Rear Access Area
The rear access area of the ATC-600 is normally accessible from
the rear of an open panel door (Figure
2
).
All wiring connections to the ATC-600 are made at the rear of the
chassis. For the sake of uniform identification, the frame of refer-
ence when discussing the rear access area is facing the back of the
ATC-600 with the panel door open. The communication module
port, for example, is located on the upper right rear of the unit. The
Run/Program Switch, used to determine the ATC-600 Mode, is
located in the lower right near the control power inputs. Detailed
information relative to any connection made to the rear access area
is presented in Section 4 entitled “Operation.”
2.3.1 Left Rear of Chassis
The left rear of the chassis provides self locking female connec-
tors J1, J2 and J3 for voltage monitoring of Source 1 (S1),
Source 2 (S2) and the Load respectively. Terminal block J4 pro-
vides DC wetted connections for various functional inputs. See
Paragraph 4.3 for more information on input functionality.
2.3.2 Right Rear of Chassis
The right rear of the chassis provides a port that will accept the
D-sub male connector of the optional Communication Module
(PONI). A self locking female connector J7 is provided for Sources
1 and 2 control power input.
Customer programming is provided through the Program/Run Tog-
gle Switch. While the switch is in the Program position, the
ATC-600 continues to operate in keeping with previously pro-
grammed setpoints.
Terminal block J5 provides dry relay contacts for primary control
outputs. Physically these relays are comprised of two latching
Form A relays for generator start contacts, and seven conven-
tional coil Form C relays necessary to complete the electrical con-
trol function.
