IB ATS-1005 For more information visit: www.eaton.comInstructional BookletEffective: March 2010 Page 7Instructions for Installation, Operation and Maintenance of theEaton ATC-600 Automatic Transfer Switch ControllerSection 2: Hardware Description2.1 GeneralThe 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 fourparts:• Operator Panel• Rear Access Area• External Hardware• Specification Summary2.2 Operator PanelThe operator panel, which is normally accessible from the outsideof a panel or door, provides a means for:• Being alerted to specific conditions• Receiving functional help• Programming• Parameter Monitoring/Selection/MeteringLEDs, a display window, pushbuttons, and a mimic bus make upthe front accessible operator panel (Figure 1).Seventeen individual LEDs are lit when performing or indicating aspecific function. For detailed information on individual LEDs referto 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 4.25inches and is able to display up to eight characters at a time. Fordetails concerning the kind of information that can be viewed inthe display window refer to Paragraph 3.3.The front operator panel supports six long-life membrane pushbut-tons. Pushbuttons accomplish their function when pressed andreleased. Refer to Paragraph 3.4 for information concerning thefunction of specific pushbuttons.2.3 Rear Access AreaThe rear access area of the ATC-600 is normally accessible fromthe rear of an open panel door (Figure 2).All wiring connections to the ATC-600 are made at the rear of thechassis. For the sake of uniform identification, the frame of refer-ence when discussing the rear access area is facing the back of theATC-600 with the panel door open. The communication moduleport, for example, is located on the upper right rear of the unit. TheRun/Program Switch, used to determine the ATC-600 Mode, islocated in the lower right near the control power inputs. Detailedinformation relative to any connection made to the rear access areais presented in Section 4 entitled “Operation.”2.3.1 Left Rear of ChassisThe 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. SeeParagraph 4.3 for more information on input functionality.2.3.2 Right Rear of ChassisThe right rear of the chassis provides a port that will accept theD-sub male connector of the optional Communication Module(PONI). A self locking female connector J7 is provided for Sources1 and 2 control power input.Customer programming is provided through the Program/Run Tog-gle Switch. While the switch is in the Program position, theATC-600 continues to operate in keeping with previously pro-grammed setpoints.Terminal block J5 provides dry relay contacts for primary controloutputs. Physically these relays are comprised of two latchingForm A relays for generator start contacts, and seven conven-tional coil Form C relays necessary to complete the electrical con-trol function.
