For the purpose of familiarization,the panel is divided into three sub-sections and discussed individ-ually:• LEDs• Pushbuttons• Display Window3.2 LEDSLEDs are used to indicate the device’s mode of operation, the statusof the system, and the operations and/or conditions of displayedfunctions. Three LEDs at the top of the ATC-600 provide a quicksnapshot of the unit’s status (Mode). Seven LEDs, just above thedisplay window, indicate which portions of the mimic bus areactive, and the actual status of both sources and load. The remain-ing seven LEDs, just below the display window, are lit to indicatethe identity of information being displayed.Automatic Mode LEDThis LED blinks green indicating that the ATC-600 is operatingand providing the transfer switch control function in keeping withprogrammed setpoints. If the LED is not lit or is on continuously, aproblem may be indicated.Test Mode LEDThis LED is lit red upon entering the Test Mode. The Test Modecan only be entered with the LEDs below the display window notlit. When a test is initiated, the Status LED lights. Both LEDs willturn off upon the successful completion of a test cycle.Program Mode LEDThis LED is lit red when the Run/Program switch on the rear of thechassis is in the Program position. This condition permits pro-gramming of control setpoints. When the setpoints LED is lit indi-cating that existing setpoints can be changed, the Program ModeLED blinks.Source 1 Available - Status LEDThis LED is lit amber if Source 1 meets the criteria for pro-grammed Source 1 setpoints.Source 1 Preferred - Status LEDThis LED is lit red if Source 1 is the preferred source choice.Source 1 Connected - Status LEDThis LED is lit green if Source 1 is connected. This is accom-plished by sensing the Source 1 breaker via the S1 closed auxil-iary contact.Source 2 Available - Status LEDThis LED is lit amber if Source 2 meets the criteria for pro-grammed Source 2 setpoints.Source 2 Preferred - Status LEDThis LED is lit red if Source 2 is the preferred source choice.Source 2 Connected - Status LEDThis LED is lit red if Source 2 is connected. This is accomplishedby sensing the Source 2 breaker via the S2 closed auxiliary con-tact.Load Energized - Status LEDThis LED is lit red if the load is connected to a source that is avail-able.Status - Display LEDThis LED is lit red when action is occurring, such as a timer timingdown, and one of the other display categories has not beenselected. When the action is completed, the display goes blankand the LED turns off. The Status position is the default positionof the display.Source 1 - Display LEDThis LED is lit green when displaying Source 1 voltage, frequency,and status information. The LED also lights when displaying spe-cific Source 1 setpoint information.Source 2 - Display LEDThis LED is lit red when displaying Source 2 voltage, frequency,and status information. The LED also lights when displaying spe-cific Source 2 setpoint information.Load - Display LEDThis LED is lit red when load voltage is being displayed.History - Display LEDThis LED is lit red when displaying historical information.Time/Date - Display LEDThis LED is lit red when displaying the time or date.Setpoints - Display LEDThis LED is lit red when displaying the programmed setpoints ofthe ATC-600. When a specific displayed setpoint is associatedwith one of the sources, the specific source LED will also be lit.NOTICEWITH RESPECT TO THEIR USE IN THIS DOCUMENT AND AS THEYRELATE TO AUTOMATIC TRANSFER SWITCH OPERATION, THEWORDS “CYCLE” AND “EVENT” ARE DEFINED AS FOLLOWS:CYCLE –A COMPLETE OPERATION FROM NORMAL TO EMERGENCYTO NORMAL.EVENT –A FAILURE RESULTING IN SOME TYPE OF SWITCH AND/ORSWITCH INTELLIGENCE ACTION.NOTICEREFER TO APPENDIX D FOR AN OVERALL VIEW OF ATC-600 OPER-ATIONS IN THE FORM OF A MENU TREE.CAUTIONLOAD ENERGIZE LED IS NOT A POSITIVE INDICATION THAT VOLT-AGE IS NOT PRESENT ON THE LOAD TERMINALS.
