Description
3398 MCB open relay 2 [N.O.] The relay "command: MCB open"
will be energized to open the MCB
and will be de-energized again
after the discrete input "Reply
MCB" is energized to signal the
control that the MCB is open.
Not used The LogicsManager relay R9 is
freely programmable. The pre-
configuration "04.22 Opening MCB
active" works similar to the "N.O."

Breaker pulse duration to close
the MCB
The time of the pulse output may
be adjusted to the breaker being
utilized.
5730 Synchronization MCB 2 [Slip frequency] The frequency controller adjusts
the frequency in a way, that the
frequency of the source (busbar)
is marginal greater than the target
(mains). When the synchronizing
conditions are reached, a close
command will be issued. The
slipping frequency is positive to
avoid reverse power.
Phase matching The frequency controller adjusts
the phase angle of the source
(busbar) to that of the target
(mains), in view of turning the
phase difference to zero.
Notes
Regardless of breaker control, the values of the following parameters 5710, 5711, 5712, 5713, 5714, 8841, and 8842 are
important to the sync-check relay function.

The prerequisite for a connect
command being issued for the
MCB is that the leading phase
angle between busbar and mains
is below the configured maximum
permissible angle.
