Glossary
With respect to their use in this
document and as they relate to switch
operation, the following terminology
is defined:
Available — A source is defined as
“available” when it is within its under-
voltage/overvoltage/underfrequency/
overfrequency (if applicable) set point
ranges for the nominal voltage and
frequency setting.
Fail-safe — A feature that prevents
disconnection from the only available
source and will also force a transfer or
re-transfer operation to the only avail-
able source.
Re-Transfer — “Re-Transfer” is defined
as a change of the load connection
from the secondary to primary source.
Source 1 — is the primary source
or Normal Source or Normal Power
Source or Normal. (Except when
Source 2 has been designated the
“Preferred Source.”)
Source 2 — is the secondary source
or Emergency Source or Emergency
Power Source or Emergency or Standby
or Backup source. (Except when
Source 2 has been designated the
“Preferred Source.”)
Source 1 — Failed or Fails — Source 1
is defined as “failed” when it is outside
of its undervoltage or overvoltage
or underfrequency or overfrequency (if
applicable) set point ranges for the
nominal voltage and frequency setting.
Source 2 — Failed or Fails — Source 2
is defined as “failed” when it is out-
side of its undervoltage or overvoltage
or underfrequency or overfrequency
(if applicable) set point ranges for the
nominal voltage and frequency setting
for a time exceeding 0.5 seconds after
the Time Delay Emergency Fail (TDEF)
time delay expires.
Transfer — “Transfer” is defined as a
change of the load connection from
the primary to secondary source
except when specifically used as
“Transfer to Neutral.”
Transfer to Neutral — “Transfer to
Neutral” is defined as when the load
circuits are disconnected from both
Source 1 and Source 2.
