If, however, external close commands which should not activate the manual close function are possible (e.g.
external reclosure device), the binary input „>Manual Close“ must be triggered by a separate contact of the
control switch (Figure 2-101).
If in that latter case a manual close command can also be given by means of an internal control command from
the device, such a command must be combined with the manual CLOSE function via parameter 1152
Man.Clos. Imp. (Figure 2-99).

Besides the manual CLOSE detection, the device records any energization of the line via the integrated line
energization detection. This function processes a change-of-state of the measured quantities as well as the
position of the breaker auxiliary contacts. The current status of the circuit breaker is detected, as described in
the following Section at „Detection of the Circuit Breaker Position“. The criteria for the line energization detec-
tion change according to the local conditions of the measuring points and the setting of the parameter address
1134 Line Closure (see Section 2.1.4 at margin heading „Circuit Breaker Status“).
