X1 1-2 Auxiliary power supply. The positive pole of the dc supply is connected
to terminal 1
3-4 Operation signal (TRIP) of relay modules, stages I>, I>>, I
6-7 Signal "Final trip on overcurrent or earth-fault; I>, I>>, I
Iϕ>>" or operation signal 2 (SIGNAL1)
8-9-10 Self-supervision signalling contact (IRF). Operates on the closed circuit
principle. Under normal conditions contact interval 8-9 is closed.
When the auxiliary power supply fails or an internal fault is detected,
the contact interval 9-10 is closed
11-12 Selection of operation characteristic, i.e. Isinϕ/Icosϕ for the directional
earth-fault module U2 (BACTRL)
X2 1-2-3 Signal "Final trip on earth-fault; Iϕ>, Iϕ>>" or signal "general protection
operation; I>, I>>, I
4-5-6 Start or operation signal (I>, I>>, I
fault relay module (SIGNAL 3)
7-8-9 Start signal (Iϕ> ) from earth-fault relay module (SIGNAL 4)
10-11 External blocking signal 2 for protection relay modules (BS2)
11-12 External blocking signal 1 for protection relay modules (BS1)
X3 1-2 Input channel 1 of control module, open status (INPUT1/O). When e.g.
the circuit-breaker is open, voltage must be applied to the input
1-3 Input channel 1 of control module, closed status (INPUT1/I). When
e.g. the circuit-breaker is closed, voltage must be applied to the input
1-4 Input channel 2 of control module, open status (INPUT2/O)
1-5 Input channel 2 of control module, closed status (INPUT2/I)
6-7 Input channel 8 of control module (INPUT 8)
6-8 Input channel 9 of control module (INPUT 9)
9-10 Input channel 12 of control module (INPUT 12)
11-12 Open output 1 of control module (OPEN 1)
13-14 Close output 1 of control module (CLOSE 1)
15-16 Open output 2 of control module (OPEN 2)
17-18 Close output 2 of control module (CLOSE 2)
