ATC-300+ Automatic
Transfer Switch Controller
Plant Exercising in the Load Exercising Mode is “Failsafe”. If the
generator fails during testing for any reason, the ATC-300+ will
signal the transfer switch to return to the Source 1 power source.
The ATC-300+ will display “FAILSAFE” until a pushbutton is
pressed.
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+ programming is just a matter
of simple, repetitive steps. However, because of the importance
placed on this function and its critical relationship to the proper
functioning of the system, 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
The ATC-300 Controller is fully programmable from the device’s
faceplate. Users can reprogram setpoints as well as other param-
eters. 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 Program
Mode.
WHILE IN THE PROGRAM MODE, THE ATC-300+ CONTROLLER IS
NEVER OFF-LINE AND CONTINUES TO FUNCTION IN ACCORDANCE
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 set-
point values.
There are five screens related to the password, which is a four-
digit number from 0000 to 9999.
