UMaxEnerg
This setting is used to block the closing when the voltage on the live side is above the
set value of UMaxEnerg.
tAutoEnerg and tManEnerg
The purpose of the timer delay settings, tAutoEnerg and tManEnerg, is to ensure that
the dead side remains de-energized and that the condition is not due to a temporary
interference. Should the conditions not persist for the specified time, the delay timer
is reset and the procedure is restarted when the conditions are fulfilled again. Circuit
breaker closing is thus not permitted until the energizing condition has remained
constant throughout the set delay setting time.
Apparatus control APC

Application

The apparatus control is a functionality for control and supervising of circuit breakers,
disconnectors, and earthing switches within a bay. Permission to operate is given after
evaluation of conditions from other functions such as interlocking, synchrocheck,
operator place selection and external or internal blockings.
The complete apparatus control function is not included in this
product, and the information below is included for understanding of
the principle for the use of QCBAY, LOCREM, LOCREMCTRL,
SCILO, SCSWI, SXCBR.
Figure 232 shows from which places the apparatus control function receives
commands. The commands to an apparatus can be initiated from the Control Centre
(CC), the station HMI or the local HMI on the IED front.
