OPERATION, MAINTENANCE, AND INSTALLATION GUIDE
2.6.1 Automatic configuration
Basic system parameters can be automat-
ically configured from the HMI: rated volt-
age, rated frequency, each supply power
distribution system type, and neutral
location will be recognized and set by
the controller. Other parameters are
set to factory values; see Chapter 4,
Navigating menu.
2.6.2 In-phase monitor
In-phase monitor is a feature that calcu-
ates the phase difference of supply lines,
preventing transfer when sources are not
in sync. The user can set On/Off from the
HMI. When the in-phase monitor is set to
On, the device measures and detects
when both sources are in sync with each
other. The ATS will allow transfer from
SOURCE 1 (S1) to SOURCE 2 (S2) only when
they are in sync with each other. Any of
these conditions will prevent source
transfer when In-phase monitor is set
to On:
• Phase difference between sources
remains greater than 5 degrees
• Phase order between sources is not
the same
• Voltage amplitude is out of range
• Phase is missing
• Voltage is asymmetric
• Frequency is out of range
• S1 and S2 contacts are not paralleled
(Closed transition only)
2.6.3 Powering supply scenarios
Device can be powered by the the follow-
ing methods:
• Direct from SOURCE 1 or SOURCE 2:
Controller and HMI are powered and ATS
can be operated electrically.
•
Controller and HMI are powered, but
load transfer cannot be performed.
• Programming port on HMI (USB port):
Only the main board is powered. Allows
software update to main device and
connection of Ekip Connect commis-
sioning tool.
