Instructions for Installation, Operation and Maintenance of the
Eaton ATC-600 Automatic Transfer Switch Controller
• History information:
Source 1 Engine Run Time
Source 2 Engine Run Time
Source 1 Available Time
Source 2 Available Time
Source 1 Connected Time
Source 2 Connected Time
Load Energized Time
Number of Transfers
All history information is in hours and minutes. Each individual
value 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 Transition
In-phase transition is an open transition with both sources in-
phase. The same anticipatory scheme used for closed transition
is also used for in-phase transition. The advance angle is calcu-
lated based on the frequency difference between the two sources
and 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 must
be less than the in-phase transition frequency difference setpoint
(0.0 to 3.0 Hz). When these conditions are met, the ATC-600
will monitor the phase difference between the two sources. The
synchronization timer will count down and be displayed as “TSIP”
while waiting for synchronization to be detected. When the
phase difference is within the advance angle window, the “trans-
fer” command is given. This is an open transition but both
sources will be in phase when the transfer occurs.
If the synchronization does not occur within a specified amount of
time, the transfer will take place under delayed transition.The
Alarm relay will energize and the failure will be logged into the
Transfer 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: Programming
5.1 Introduction
The ATC-600 is fully programmable from the device’s faceplate or
through the communications port. Users can reprogram setpoints
as well as other parameters. The time and date can be changed
while the device is in either the Run Mode or the Program Mode.
Setpoints, however, can only be changed while the device is in
the Program Mode.
5.2 Entering and Exiting the Program Mode
To enter the Program Mode, move the Run/Program Toggle
Switch located on the right rear chassis to the Program position.
Once the Program Mode is activated, the Program LED blinks red
and continues until the Program Mode is exited.
When programming changes have been completed, the Program
Mode is exited by moving the Run/Program Toggle Switch back to
the Run position. At that point, the Automatic LED continues to
blink 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 are
saved in the device’s non-volatile memory.
5.3 Programming Procedures
Once the Program Mode has been entered, use the Display Select
Pushbutton to move to the Setpoints Display. The Setpoints LED
will be lit red and the first programming possibility will appear in
the display. Use the Step Pushbutton to move from one feature
setpoint to another, stopping at those in need of reprogramming.
Use the Increase or Decrease Pushbuttons to move the display to
a new setpoint selection. Once a new setpoint selection has been
made, move to the next feature in need of change. Once all set-
points are displayed as required, exit the Program Mode and the
new setpoints are automatically stored.
NOTICE
IF THE ATC-600 RUN/PROGRAM SWITCH IS IN THE PROGRAM POSI-
TION, THE SETPOINTS CANNOT BE DOWNLOADED OVER IMPACC.
NOTICE
ALTHOUGH ALL ATC-600 PROGRAMMABLE FEATURES ARE
ADDRESSED IN THIS SECTION, ONLY THOSE ORDERED BY THE
CUSTOMER AND INITIALLY PROGRAMMED AT THE FACTORY WILL
APPEAR IN THE DISPLAY FOR PROGRAMMING CHANGES IN THE
FIELD.
NOTICE
WHILE IN THE PROGRAM MODE, ATC-600 IS NEVER OFF-LINE AND
CONTINUES TO FUNCTION IN ACCORDANCE WITH PREVIOUSLY
PROGRAMMED SETPOINTS.
NOTICE
IF NO PUSHBUTTON ACTIVITY IS DETECTED FOR APPROXIMATELY
2 1/2 MINUTES WHILE IN THE PROGRAM MODE, THE SETPOINTS
LED IS CLEARED AND THE ALPHA-NUMERIC DISPLAY IS BLANKED.
ANY PREVIOUSLY MADE SETPOINT CHANGES ARE NOT SAVED,
SHOULD THIS OCCUR.
NOTICE
WHEN THE TOGGLE SWITCH IS IN THE PROGRAM POSITION,
REMOTE COMMUNICATIONS PROGRAMMING IS INHIBITED.
