Program Mode - Eaton ATC-300 Mode D'emploi

In-phase transition is an open transition with both sources in-
phase. An anticipatory scheme is used for controlling the cir-
cuit breakers. The advance angle is calculated based on the
frequency difference between the two sources and also the
response time of the breaker. This results in the optimum
reconnect angle of 0 degrees for all of the frequency differ-
ence values.
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-300 Controller will monitor the phase difference
between the two sources. The synchronization timer will
count down and be displayed as "SYNC TIME" while waiting
for synchronization to be detected. When the phase differ-
ence is within the advance angle window, the "transfer"
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 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 fre-
quency difference or the phase difference was excessive.

5.10 Program Mode

The ATC-300 Controller is fully programmable from the
device's faceplate once the Password has been correctly
entered. Any operator associated with programming the
ATC-300 Controller will quickly discover that ATC-300 pro-
gramming is just a matter of simple, repetitive steps. How-
ever, because of the importance placed on this function and
its critical relationship to the proper functioning of the sys-
tem, Section 6 of this manual is dedicated to the Program
Mode. Refer to that section and Table 2 for details.

SECTION 6: PROGRAMMING
6.1 Introduction
ALTHOUGH ALL ATC-300 CONTROLLER PROGRAMMABLE FEA-
TURES ARE ADDRESSED IN THIS SECTION, ONLY THOSE
ORDERED BY THE CUSTOMER AND INITIALLY PROGRAMMED AT
THE FACTORY WILL APPEAR IN THE DISPLAY FOR PROGRAM-
MING CHANGES IN THE FIELD.
The ATC-300 Controller is fully programmable from the
device's faceplate or remotely through the communications
port. Users can reprogram setpoints as well as other parame-
ters. The time, date, and setpoints can only be changed
while the device is in the Program Mode.
Program Mode is achieved by entering a valid password when
prompted by the Setpoints screens. The Unit Status LED will
blink at a faster rate when viewing the setpoints while in Pro-
gram Mode.
WHILE IN THE PROGRAM MODE, THE ATC-300 CONTROLLER IS
NEVER OFF-LINE AND CONTINUES TO FUNCTION IN ACCOR-
DANCE WITH PREVIOUSLY PROGRAMMED SETPOINTS.
6.2 Password
To enter the Program Mode, the ATC-300 Controller requires
a password to prevent unauthorized persons from modifying
setpoint values.
There are five screens related to the password, which is a
four-digit number from 0000 to 9999.
1.
Use the Increase or Decrease pushbuttons to select Yes, then
use the Step/Enter pushbutton to enter the selection and
move to the next screen
2.
Use the Increase or Decrease pushbuttons to select Yes or
No, then use the Step/Enter pushbutton to enter the selection
and move to the next screen. If No is selected, the user will
be able to review the setpoints but not make any changes. If
Yes is selected, the Password screen will appear.
3.
Use the Increase or Decrease keys to scroll to the desired
value (0 - 9) for the first digit, then use the Step/Enter key to
enter the value and move to the next digit. Repeat for
remaining three digits. After all four numerals of the pass-
word are entered, press the Step/Enter pushbutton to enter
the password and proceed to the next screen. If an invalid
password is entered, the LCD Display shall read "Invalid Pass-
word" and the user must press the Step/Enter pushbutton to
initiate another password entry sequence.
Note:The factory default password is "0300". If the password is for-
gotten, contact the factory for the backdoor password.
