Instructions for Installation, Operation and Maintenance of the
Eaton ATC-600 Automatic Transfer Switch Controller
Section 3: Operator Panel
3.1 General
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, and parameter
monitoring/selection (Figure
1
). For the purpose of familiarization,
the panel is divided into three sub-sections and discussed individ-
ually:
•
LEDs
•
Pushbuttons
•
Display Window
3.2 LEDS
LEDs are used to indicate the device’s mode of operation, the status
of the system, and the operations and/or conditions of displayed
functions. Three LEDs at the top of the ATC-600 provide a quick
snapshot of the unit’s status (Mode). Seven LEDs, just above the
display window, indicate which portions of the mimic bus are
active, and the actual status of both sources and load. The remain-
ing seven LEDs, just below the display window, are lit to indicate
the identity of information being displayed.
Automatic Mode LED
This LED blinks green indicating that the ATC-600 is operating
and providing the transfer switch control function in keeping with
programmed setpoints. If the LED is not lit or is on continuously, a
problem may be indicated.
Test Mode LED
This LED is lit red upon entering the Test Mode. The Test Mode
can only be entered with the LEDs below the display window not
lit. When a test is initiated, the Status LED lights. Both LEDs will
turn off upon the successful completion of a test cycle.
Program Mode LED
This LED is lit red when the Run/Program switch on the rear of the
chassis 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 Mode
LED blinks.
Source 1 Available - Status LED
This LED is lit amber if Source 1 meets the criteria for pro-
grammed Source 1 setpoints.
Source 1 Preferred - Status LED
This LED is lit red if Source 1 is the preferred source choice.
Source 1 Connected - Status LED
This 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 LED
This LED is lit amber if Source 2 meets the criteria for pro-
grammed Source 2 setpoints.
Source 2 Preferred - Status LED
This LED is lit red if Source 2 is the preferred source choice.
Source 2 Connected - Status LED
This LED is lit red if Source 2 is connected. This is accomplished
by sensing the Source 2 breaker via the S2 closed auxiliary con-
tact.
Load Energized - Status LED
This LED is lit red if the load is connected to a source that is avail-
able.
Status - Display LED
This LED is lit red when action is occurring, such as a timer timing
down, and one of the other display categories has not been
selected. When the action is completed, the display goes blank
and the LED turns off. The Status position is the default position
of the display.
Source 1 - Display LED
This 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 LED
This 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 LED
This LED is lit red when load voltage is being displayed.
History - Display LED
This LED is lit red when displaying historical information.
Time/Date - Display LED
This LED is lit red when displaying the time or date.
Setpoints - Display LED
This LED is lit red when displaying the programmed setpoints of
the ATC-600. When a specific displayed setpoint is associated
with one of the sources, the specific source LED will also be lit.
NOTICE
WITH RESPECT TO THEIR USE IN THIS DOCUMENT AND AS THEY
RELATE TO AUTOMATIC TRANSFER SWITCH OPERATION, THE
WORDS “CYCLE” AND “EVENT” ARE DEFINED AS FOLLOWS:
CYCLE –A COMPLETE OPERATION FROM NORMAL TO EMERGENCY
TO NORMAL.
EVENT –A FAILURE RESULTING IN SOME TYPE OF SWITCH AND/OR
SWITCH INTELLIGENCE ACTION.
NOTICE
REFER TO APPENDIX D FOR AN OVERALL VIEW OF ATC-600 OPER-
ATIONS IN THE FORM OF A MENU TREE.
CAUTION
LOAD ENERGIZE LED IS NOT A POSITIVE INDICATION THAT VOLT-
AGE IS NOT PRESENT ON THE LOAD TERMINALS.
