Functions
The ATS is an automatic switch system integrating control and power distribution.
It supports and detects the three-phase inputs from two power sources (DG 1 and
mains or DG 1 and DG 2) and switches between the two power inputs. The power
source can switch to DG 1 by turning the bypass switch. The following table
describes the ATS functions.

AC power
distribution
Provides one route of three-phase AC power distribution for
downstream loads, one 10 A AC output, and one reserved
maintenance socket output.
Power source
switching
Provides a bypass switch that allows the power source to
switch to DG 1.
Monitoring Monitors the voltage, current, frequency, and power factor
of three-phase outputs.
Protection Protects against mains overvoltage, mains undervoltage,
DG overvoltage, and DG undervoltage.
Alarming Generates alarms for mains open phase and DG open
phase.
