ATC-300 Automatic
Transfer Switch Controller
If the LCD Display is displaying the Home screen when the Help/
Lamp Test key is pressed, all of the LED’s will momentarily illumi-
nate, then the following information will scroll across the display:
• Serial number of the ATC-300 Controller;
• Hardware revision number (= parts list revision number);
• Software version and revision number;
• Feature code – a decodable string listing all optional features
programmed in the ATC-300 Controller; and
• Firmware version.
Engine Test Pushbutton
The Engine Test pushbutton allows the user to test the Source 2
(generator) engine. The engine test function can be set with the
ATC-300 Controller to one of three setpoint modes to allow flexi-
bility in how the test is run:
0 No Load Engine Test;
1 Load Engine Test; or
2 Disabled.
The factory default is set to 1 - Load Engine Test.
For complete information on the Engine Test function, see Sec-
tion 5.7.
Step/Enter Pushbutton
The Step/Enter pushbutton allows the user to scroll through the
information and setpoint displays. By pressing the Step/Enter
pushbutton, the information on the LCD Display will advance
through the voltage(s), frequency, and status condition of Source
1, then Source 2, then the time and date information, then the
history information, then the setpoints. The information on the
LCD Display advances one step through the displayed information
cycle with each depression of the Step/Enter pushbutton.
Increase Pushbutton
The Increase pushbutton allows the user to increase the value of
the setpoints. When ATC-300 Controller is in the “Program”
Mode (to change setpoint values), each time the Increase push-
button is pressed, the value of the displayed item will increase by
one.
Decrease Pushbutton
The Decrease pushbutton allows the user to decrease the value
of the setpoints. When ATC-300 Controller is in the “Program”
Mode (to change setpoint values), each time the Decrease push-
button is pressed, the value of the displayed item will decrease
by one.
Alarm Reset Function (Increase + Decrease Pushbuttons)
Pressing the Increase and Decrease pushbuttons simultaneously
will reset the Alarm function. In addition, if both pushbuttons are
pressed simultaneously while viewing any of the historical logged
values in the program mode, the value of the current item dis-
played resets to zero.
Bypass Time Delay Function (Step/Enter + Help/Lamp Test)
Pressing the Step/Enter and Help/Lamp Test pushbuttons simulta-
neously will bypass the TDNE or TDEN functions when they
actively counting. The “Bypass TDNE/TDEN” function does not
have a user accessible, programmable setpoint for enable or dis-
able.
2.3 Rear Access Area
The rear access area of the ATC-300 Controller is normally accessible
from the rear of an open panel door (Figure 2).
Figure 2. ATC-300 Controller (Rear View).
All wiring connections to the ATC-300 Controller are made at the
rear of the chassis.
Note: To allow for uniform identification, the frame of reference when dis-
cussing the rear access area is with the panel door open and the User fac-
ing the back of the ATC-300 Controller.
Located at the left rear of the chassis are connectors J1, J2, and
J7. J1 and J2 provide for voltage monitoring of Source 1 and
Source 2 respectively. J7 is provided for Sources 1 and Source 2
control power input. Located at the right rear of the chassis is
the J3 programming port connector. The J4 and J5 connectors
are located at the bottom of the controller. The J4 connector
provides DC wetted connections for various control inputs. The
J5 and J8 connectors provide dry relay contacts for primary con-
trol outputs.
See Section 5.5.1 for contact ratings.
