3.2 Input phase The measuring phase of the UL1, UL2, UL3 line voltage, which can be of
a single-phase (phase-neutral) or two-phases (phase-phase). (Only availa-
ble in terminals intended for one bay).
3.3 UMeasure Selection of single-phase (phase-neutral) or two-phase (phase-phase)
measurement.(Only available in terminals intended for several bays).
3.4 AutoEnerg and
ManEnerg
Two different settings can be used for automatic and manual closing of the
circuit breaker.
Off The energizing condition is not used only the synchro-
check.
DLLB The line voltage U-line is low, below (10-80% Ur/sqr3)
and the bus voltage U-bus is high, above (70-100% Ur/
sqr3).
DBLL The bus voltage U-bus is low, below (10-80% Ur/sqr3))
and the line voltage U-line is high, above (70-100% Ur/
sqr3)).
Both Energizing can be done in both directions, DLLB or
DBLL.
tAutoEnerg The required consecutive time of fulfillment of the ener-
gizing condition to achieve SYN1-AUTOOK.
tManEnerg The required consecutive time of fulfillment of the ener-
gizing condition to achieve SYN1-MANOK.
