Apparatus control

Functionality

The apparatus control function APC8 for up to 8 apparatuses is used for control and
supervision 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.
In normal security, the command is processed and the resulting position is not
supervised. However with enhanced security, the command is processed and the
resulting position is supervised.
The switch controller SCSWI initializes and supervises all functions to properly select
and operate switching primary apparatuses. Each of the 8 switch controllers SCSWI
may handle and operate on one three-phase apparatus.
Each of the 3 circuit breaker controllers SXCBR provides the actual position status
and pass the commands to the primary circuit breaker and supervises the switching
operation and positions.
Each of the 7 circuit switch controllers SXSWI provides the actual position status and
pass the commands to the primary disconnectors and earthing switches and supervises
the switching operation and positions.
