Wiring description PWR (voltage supply)
Attention!
For devices with integrated heating, the supply voltage must be wired with a minimum
0.5mm
2
(recommended 0.75mm

) core cross section. It is not possible to loop the supply
voltage through to other loads!
Connection description SERVICE (PC or MSD 1 101)
To be able to use the service interface, the Module 50 ( RS 232 ) must be activated.
You can then connect a PC or a service display MSD 1 101 to the SERVICE interface of the
MS 34 105
The connection between the MSD 1 101 and the MS 34 105 is established via the pre-
configured cable KB 034 2000.
A PC can also be connected directly to the SERVICE socket of the MS 34 105 using either
a user-configured cable or the subbed plug inside the MSD 1 101.The pin configuration of
the 9-pin sub-D connector corresponds to a standard RS232 interface: 2 = RxD, 3 = TxD,
5 = GND.
Connection description SW IN/OUT (Switching Input/Output)
You can configure the switching input and output according to your requirements. Please
refer to figure 7.8. If you use a sensor with a standard M12 connector, then please note the
following:
Attention!
Only use sensors without switching output on pin 2 or sensor wiring configured without
pin 2, as the switching output is not protected against feedback. For example, having the
inverted sensor output incident on pin 2 leads to erroneous behaviour of the switching out-
put.
