of a 58-pin control wiring socket.
36.2 Control wiring socket
36.3 Centres for coding pins and bores
36.4 Bore for the actuating pin on the control wiring plug
for controling the auxiliary switch.
Coding:
(...) In brackets is stated
the corresponding coding
designation for the
control wiring plug (10.2)
The coding pins can
be tted in the
control wiring socket (10.1)
and/or in the
control wiring plug. (10.2)
Basic design:
Number of sockets optional,
but always with the
basic assignment:
1, 8, 10, 20, 21, 31, 33, 40.
Sockets and pins can be
mixed in the control wiring
socket (10.1) and control
wiring plug (10.2) as required
