SECTOIN 1 : INTRODUCTION
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.
WARNING
High voltage can kill.
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.
