4.2.5 Local panel (back-up
panel)
The connection of an external local panel to the apparatus control mod-
ules is done via binary inputs. Fig. 25 shows one example of a solution.
This solution of local control considers the interlocking function. The
panel can also be used as an back-up panel, but the outputs from the panel
are then connected directly to the high-voltage apparatuses. The position
indications are normally directly connected to the panel to get independ-
ent information about the apparatus positions. At use as back-up panel,
the select and execute inputs into the control terminal must be blocked, for
example, with AND gates with the condition no back-up.
