9.2.5 Follow function for breaker control in MAN mode
Using setpoint ProcessControl:BrkCtrl in MAN behavior of breaker control can be adjusted.
PROCESSCONTROL:BRKCTRL IN
MAN
Breaker is controller by the controller. It is possible to fault reset
(press fault reset twice) MCB fail alarm which happened due to
previous incorrect manipulation with the breaker. This is possible
if the breaker was closed externally and the Mains is healthy
(there is no Level 2 alarm and no alarm with MGCB). Controller
accepts the state of the breaker and continues in normal
operation.
Breaker is controlled externally and by the controller as well
(closing or opening of the breaker can be done manually or can
be issued by the pressing of MCB/MGCB button on the
controller). Synchronization process can be started by the
FORCE SYNC input if it is allowed by the
setpoints ProcessControl:Synchro enable and
ProcessControl:ParallelEnable (Synchro enable must be set to
BOTH, REVERSE (MCB is not closed, MGCB is closed!),
FORWARD (MGCB is not closed, MCB is closed!) and
ParallelEnable must be set to ENABLED). Synchronization in
FOLLOW does not have any timeout and controller keeps
voltages synchronized indefinitely (i.e. until FORCE SYNC is
opened or the breaker is closed externally). The synchronization
can be also denied for other reasons (e.g.
ProcessControl:MainsCoupling is no enabled).
WARNING!
In the FOLLOW mode, the controller buttons are still active in MAN mode. Therefore it is possible to
control the breaker manually or by the pressing of corresponding button on the controller! To ensure
no injuries and/or damage always operate the breaker with extreme caution and prevent other
personell from manipulating the breaker by the controller buttons. If necessary, use the MCB and/or
MGCB DISABLE function!
