Each individualvalue is resettable over IMPACC.• Time-stamped history (time/date/reason) for all previous trans-fers.• Capability to initiate an engine test.• Updates the ATC-600 real-time clock.4.9 In-phase TransitionIn-phase transition is an open transition with both sources in-phase. The same anticipatory scheme used for closed transitionis also used for in-phase transition. The advance angle is calcu-lated based on the frequency difference between the two sourcesand also the response time of the breaker. This results in the opti-mum reconnect angle of 0 degrees for all of the frequency differ-ence values.The criteria for in-phase transition are similar to closed transition.Both sources must be available and the frequency difference mustbe less than the in-phase transition frequency difference setpoint(0.0 to 3.0 Hz). When these conditions are met, the ATC-600will monitor the phase difference between the two sources. Thesynchronization timer will count down and be displayed as “TSIP”while waiting for synchronization to be detected. When thephase difference is within the advance angle window, the “trans-fer” command is given. This is an open transition but bothsources will be in phase when the transfer occurs.If the synchronization does not occur within a specified amount oftime, the transfer will take place under delayed transition.TheAlarm relay will energize and the failure will be logged into theTransfer History as either “Sync Fail - Freq” or “Sync Fail - Phase”depending on whether the frequency difference or the phase dif-ference was excessive.Section 5: Programming5.1 IntroductionThe ATC-600 is fully programmable from the device’s faceplate orthrough the communications port. Users can reprogram setpointsas well as other parameters. The time and date can be changedwhile the device is in either the Run Mode or the Program Mode.Setpoints, however, can only be changed while the device is inthe Program Mode.5.2 Entering and Exiting the Program ModeTo enter the Program Mode, move the Run/Program ToggleSwitch located on the right rear chassis to the Program position.Once the Program Mode is activated, the Program LED blinks redand continues until the Program Mode is exited.When programming changes have been completed, the ProgramMode is exited by moving the Run/Program Toggle Switch back tothe Run position. At that point, the Automatic LED continues toblink green, the alphanumeric display shows the word “Program”for a short period, and the Program LED will no longer be illumi-nated. It is also at that point when any setpoint changes aresaved in the device’s non-volatile memory.5.3 Programming ProceduresOnce the Program Mode has been entered, use the Display SelectPushbutton to move to the Setpoints Display. The Setpoints LEDwill be lit red and the first programming possibility will appear inthe display. Use the Step Pushbutton to move from one featuresetpoint to another, stopping at those in need of reprogramming.Use the Increase or Decrease Pushbuttons to move the display toa new setpoint selection. Once a new setpoint selection has beenmade, move to the next feature in need of change. Once all set-points are displayed as required, exit the Program Mode and thenew setpoints are automatically stored.NOTICEIF THE ATC-600 RUN/PROGRAM SWITCH IS IN THE PROGRAM POSI-TION, THE SETPOINTS CANNOT BE DOWNLOADED OVER IMPACC.NOTICEALTHOUGH ALL ATC-600 PROGRAMMABLE FEATURES AREADDRESSED IN THIS SECTION, ONLY THOSE ORDERED BY THECUSTOMER AND INITIALLY PROGRAMMED AT THE FACTORY WILLAPPEAR IN THE DISPLAY FOR PROGRAMMING CHANGES IN THEFIELD.NOTICEWHILE IN THE PROGRAM MODE, ATC-600 IS NEVER OFF-LINE ANDCONTINUES TO FUNCTION IN ACCORDANCE WITH PREVIOUSLYPROGRAMMED SETPOINTS.NOTICEIF NO PUSHBUTTON ACTIVITY IS DETECTED FOR APPROXIMATELY2 1/2 MINUTES WHILE IN THE PROGRAM MODE, THE SETPOINTSLED IS CLEARED AND THE ALPHA-NUMERIC DISPLAY IS BLANKED.ANY PREVIOUSLY MADE SETPOINT CHANGES ARE NOT SAVED,SHOULD THIS OCCUR.NOTICEWHEN THE TOGGLE SWITCH IS IN THE PROGRAM POSITION,REMOTE COMMUNICATIONS PROGRAMMING IS INHIBITED.
