Dummy plug
1
Interlock connector, D-Sub, 25-pin (dummy plug)
Label: “
X105; Interlock CTR 4”
Is connected on the rear side of all devices to interface X105.
2
Interlock or CAN-Term, D-Sub, 9-pin (dummy plug)
Label: “
X101; CAN TERM; Interlock CTR 4
“
Is connected to interface X101 on the rear side of the device at the start of the
CAN multi-unit system.
3
CAN-Term, D-Sub, 9-pin (dummy plug)
Label: “
X102; CAN TERM;”
Is connected to interface X102 on the rear side of the device at the end of the
CAN multi-unit system.

5.3.2.
Interlock circuit in a multi-unit system
If the interlock circuit is used in a multi-unit system, there are changes
compared to operation using an individual power supply. The principles
of function and usage with a single device are described in the interlock
circuit chapter 3.2.4.8, page 65 and interlock output inhibit chapter
3.3.1, page 71.
So that a multi-unit system can also be operated with a single interlock
contact, the interlock circuit for all devices in the system must be sup-
plied from a 24 V auxiliary supply (any device).
Note that the dummy plugs for the interfaces X101/X102 have similar
cases, however internally the interlock wiring is different and therefore a
differentiation must be made!
