SECTION 3 : OPERATION
3.1 General
The five functions of the ATS-33
：
● Automatic mode
● OFF mode
● Bypass mode
● Programming mode
● KCU-XX Remote Communication
The practical use of each operation under each
category will be explained in this section. It is assumed
that prior sections are understood, and the operator
has a basic understanding of the hardware.
3.2 AUTO Mode
The AUTO mode of the ATS-33 controller provides for
automatic start, transfer and retransfers from source to
source as dictated by the programmed values.
The ATS-33 controller constantly monitors the
condition of both generators
’ power sources thus
providing the required intelligence for transfer
operations.
For example, the ATS-33 control unit automatically
initiates a start and transfer of power when the working
generator duty time countdown to zero or when power
fails or voltage level drops below a preset value at its
duty time. Exactly what the ATS-33 controller will
initiate in response to a given system condition
depends upon the combination of standard and
selected optional features.
3.3 OFF Mode
In OFF the ATS-33 disables all the transfers and
protection functions, the display window and all the
LEDs are turned off.
Both remote start signals are also disabled in OFF and
the ATS can’t transfer the load to any source
automatically.
However, when programming, the OFF button allows
you to move to the next program line and then change
the values for that line using down (▼) and up (▲)
buttons.
Controller Panel Lighting Test
This checks the LED lights. Press the OFF button, all
panel LEDs must light up.
3.4 Bypass Mode
If the ATS-33 is running in AUTO, pressing the bypass
button ignores its current duties and force starts the
next generator, and
transfer’s power from this
generator to the other. If the second generator fail to
start or its voltage and frequency does not become
available, the controller keeps the load connected to
the working generator and triggers an alarm.
Activate the Bypass only when in AUTO.
3.5 Programming Instruction
You program the ATS-33 from the front faceplate.
To start, set the controller to OFF and press & hold the
OFF button for 4 seconds. The word “Vr1.0” appears
on the display for 2 seconds, showing the software
version.
You are now ready to start the line-by-line
programming sequence. Always press the OFF key to
move to the next line. To change the parameter, on
each line use the up (▲) and down (▼) arrows.
Repeatedly pressing the up (▲) or down (▼) key,
changes the displayed by one. To change faster, hold
the buttons down.
Remember to always press the “OFF” button to move
to
the next line or until the “End” appears on the screen.
Note :
To end and exit at any time, hold the “OFF” key
down for 4 seconds.
If you make an error or need to return to factory
settings, stay or reenter programming and then hold
the AUTO keys down for 4 seconds, until the word
“Au.Po” appears on the screen verifying that all
programming lines are factory reset back like in the
manual. (See line-by-line programming table for
ATS-33 factory settings).
