SECTION 1 : INTRODUCTION
1.1 Preliminary Comments and Safety Precautions
The manual covers installation, operation and
maintenance of the ATS-PLC Automatic Transfer
Switch Controller. This manual is for use by authorized
and qualified personnel only.
1.2 Overview
Transfer switches protect critical electrical loads
against loss of power. A standby (emergency)
generator backs up the normal grid power. The transfer
switch connects either the normal or the standby
supply to the load. When power is lost from the grid,
the transfer switch transfers the load to the standby
source. Eventually after the grid is restoration, the ATS
connects the load back to the grid.
1.3 Product Overview
The ATS-PLC is a programmable multifunction
touch-screen automatic transfer switch control unit with
built in 5.7” inch color touch screen. The compact
design easily replaces the general conventional ATS
controlling circuit board and controllers. The interface
is user friendly with plenty of preferred settings and
configuration to suit user preference. Suited for single
phase/3 phase 3 wires/ 3 phase 4 wires systems.
The multi parameter setting ranges enables the
controller to operate on all kinds of ATS transfer
Switches and the customizable features to fulfill the
operator’s needs. All configurations are stored in the
internal program memory to prevent loss of data or
important settings during a power outage.
1.4 Functions / Features
● Microcomputer program control, compact size and
easy installation.
● 5.7” inch color LCD touch-screen.
● Program and function setting via touch-screen
operation.
● Voltage, current, frequency and KVA readings for
normal and standby power and current time display.
● Voltage, current and frequency readings displayed
digitally in numeric or gauge type display.
● Normal and standby power full phase voltage
monitoring and protection.
● Normal and standby power frequency monitoring
and protection.
● Normal and standby reverse phase sequence
protection.

● Optional 1 to 4 weeks automatic scheduled exercise
/ testing.
● Pre-alert warning signal output for scheduled
automatic Exercise / testing.
● Transfer failure alarm.
● Full compatibility with all types of ATS switches.
● Optional USB / RS485 / Ethernet remote (mobile
proxy) communication functions.
● Program on-site or from remote (mobile) device (PC,
Smart Phone).
● Program on-site or from remote (mobile) device (PC,
Smart Phone).
● Permanent stored configuration, prevent loss of data
during power outage.
● Front panel display provides source status and fail
alarm indications.
● Built-in 40 sets of event log.
● Built-in 4 digits password protection.
