1.1 Preliminary Comments and Safety Precautions
This document covers installation, operation and
maintenance of the ATS-34 Automatic Transfer Switch
Controller. This manual is for the use of authorized and
qualified personnel only.
1.2 Product Overview
We use the ATS-34 to control the second ATS in a
redundant emergency ATS system. A redundant ATS
system consists of two ATS, the first ATS being a
normal standard ATS that triggers the second ATS
using the ATS-34 control. This second ATS control
selects which backup generator is the first to run and in
the case of a fail start or a breakdown restores power
by switching to a second generator. This line circuit
illustrated how it works.
The ATS-34 Controller provides programming flexibility
for the two backup generators. Therefore, the ATS
switch operates properly through a series of sensing
and timing functions.
ATS-34 controller allows you to control the generator
duty cycle and alternate operation of the two
generators.
The ATS-34 control unit features：
● Microprocessor based with touch screen.
● Smart touch screen (touch sensor) design.
● Compact size with user-friendly LED display.
● Programmable for cycle-mode or fix-mode displays
for 3-phase and 1-phase voltages and frequencies.
● All programming and operations are done from the
front screen interface.
● Monitors over and under voltages for both primary
and secondary generators.
● Monitors over and under frequency for both primary
and secondary generators.
● Dry-contact alarm for transfer fail and over-cranking.
● Manual force-bypass.
● Compatible with almost all ATS switches.
● Optional USB / RS485 / Ethernet remote (mobile
proxy) communication functions.
● Program on-site or from remote (mobile) device (PC,
Smart Phone).
● Auto-saved settings (memory preserved throughout
all power disconnects and resets).
● Front panel display provides source status and fail
alarm indications.
1.3 Functions / Features
The primary function of ATS-34 controller is to monitor
power sources and provide the necessary intelligence
to operate a seamless and automatic transfer of load
between two generators.
1.3.1 Operational Simplicity
From installation to programming and to usage, the
ATS-34 controller is designed with operational
simplicity in mind. The user-friendly front panel
interface simplifies routine operation, programming
and setting adjustments.
1.3.2 Standard Features
All logic settings for different ATS’s are
preprogrammed and stored in its non-volatile
random-access memory (NVRAM), this memory
retains its information when power is turned off. Some
features and set points are user adjustable.
___________________________________________________________________________________________
ATS-34 3
Feature 1 : Generator Duty Cycle – start attempts
settings
You can program the ATS-34 to switch the lead
generator duty by time or start-run attempts. When the
working generator times out, or runs a number of times
the ATS-34 starts the next generator and makes this
one the lead generator. (See lines 3 & 4)
Adjustable duty time range：0 250 Hours
Feature 2 : Transferring Time Delay
The ATS-34 controller provides a time delay when
transferring from one generator to the other.
Countdown begins when the standby source becomes
available. (See line 5)
Adjustable time delay range：0 250 sec
Feature 3 : Time Delay Engine Cool-down
Controller permits the generator to run unloaded (cool
down) after transferring to the other generator.
Countdown starts when the transfer is completed. (See
line 6)
Adjustable time delay range：0 250 sec
Feature 4 : Time Delay OFF Position
Time Delay on OFF stops the switch in the center OFF
position (completely disconnected) before transferring
to the other generator. (See line 7)
Adjustable time delay range：0 99 sec
Feature 5 : Under / Over voltage Sensing
The controller monitors the output voltage for both
generators. You can set the working voltage window on
lines 8, 9, 10, 14, 15 & 16
Adjustable over voltage range：110 520 Vac
Adjustable under voltage range：80 470 Vac
Feature 6 : Under / Over frequency Sensing
The controller also monitors the Hertz for each
generator. (see line 11, 12, 13, 17, 18 & 19)

2.3.3 Auto Button
When selecting the AUTO key, the ATS-34 runs in
automatic mode lighting the corresponding LED to
indicate the selection. The controller automatically
starts the generator, transfer and retransfers from
source to source as commanded by the features
supplied and the preprogrammed setting.
In AUTO, all anomaly are accompanied by its
matching alarm output make sure all failures are
corrected before touching the auto key to reset the
alarm signal.
2.3.4 Bypass Function Button
The Bypass button provides for a manual override of
pre-programmed functions. When the ATS-34 is in
AUTO, touching the Bypass key ignores the current
timers and setting, and the controller will force-start the
second generator and transfer the switch from the
current working generator to the second generator.
The Bypass function can be activated only in AUTO.
2.3.5 OFF Button
Touching the OFF key, turns the ATS-34 OFF
engaging a flashing red LED instantly disabling all

WARNING
A remote start signal can activate the ATS-34 and
the engines can start at anytime without warning.
Place a “Danger” warning sign next to the
generator, stating that this generator can start at
anytime! also install a warning buzzer or a flash
light. Unexpected engine starts can result in
serious injury or death. When performing service
or maintenance, always disconnect the remote
start signal input.
SECTOIN 3 : OPERATION
3.1 General
five functions of the ATS-34：
● 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-34 controller provides for
automatic start, stop, and transfer and retransfers from
source to source as dictated by the programmed
values.
The ATS-34 controller constantly monitors the
condition of both generators’ power sources thus
providing the required intelligence for transfer
operations.
3.3 OFF Mode
In OFF the ATS-34 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.
3.4 Bypass Mode
If the ATS-34 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.
