The connection of an external local panel to the apparatus control modules is done via
binary inputs. Figure 105 shows one example of a solution. This solution of local con-
trol 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 appara-
tuses. The position indications are normally directly connected to the panel to get inde-
pendent 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.
