SECTION 1 : INTRODUCTION
1.1 Preliminary Comments and Safety Precautions
This technical document is intended to cover most
aspects related with the installation, operation and
maintenance of the ATS-33 Automatic Transfer Switch
Controller. This manual is for authorized and qualified
personnel only.
WARNING
High voltage will cause severe injury or death
1.2 Product Overview
The ATS-33 controller represents a state-of
–the-art
advancement in automatic transfer switch controls,
where utility power is unavailable and generators must
be in a constant operational state. The ATS-33 design
is specifically tailored for the dual generator power
system: a two-generator system, one primary generator
and its back-up or stand-by generator. The ATS-33
controller manages the automatic start-up and transfer
of load between the primary and stand-by generators,
whether the power-loss is an unexpected event or
scheduled.
Additionally,
the
controller
can
be
programmed to deliver a set operation duty cycle,
which enables both the primary and stand by
generators to operate in relay duty.
The ATS-33 Controller provides an unmatched degree
of programmed flexibility. It provides all the necessary
administration to ensure that the ATS switch operates
properly through a series of programmed sensing and
timing functions.
Controller

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-33 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-33 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.
