OTE
:
The vectorshift protection is recorded into the history file, however it is not
indicated in the Alarm list. When it occurs the controller opens either MCB or
MGCB depending on the setpoint
VectorS CB sel . If the MCB is not
controlled in the particular application then MGCB is opened.
N
OTE
:
If a vectorshift is detected and consequently the MCB is opened, however
mains voltage and frequency remain in limits, the MCB is then reclosed again
after
Mains ret del , as the mains is evaluated as healthy.
N
OTE
:
Parallel operation is in this case considered only if there is at least one
ComAp controller with closed GCB to the bus. If MCB and MGCB are closed
and there is no ComAp controller on the Bus connected via CAN2 to the
InteliMains and with closed GCB, this situation cannot be considered as
parallel operation because of the function of
MGCBparalClose .

OTE

If the MGCB is selected and a mains failure occurs the MGCB will be opened
immediately when the vectorshift or ROCOF is detected, however also MCB
will be opened consequently due to other mains protection as
underfrequency or undervoltage.
