Electrical Connection - Labom PASCAL CS Operating Instructions Manual

After the mechanical installation and the electrical connection are both complete, the
device is ready for use as soon as the voltage supply is switched on.

3.1 Electrical Connection

Make all electrical connections with the voltage supply switched off.

3.1.1 Connecting the switching outputs (optional)
The switching outputs are potential-free.
They are electrically isolated from the
supply side (see Figure 2).
Therefore you can connect the load on the
high-side (PNP-style) or the low-side
(NPN-style) as long as you use only one
switching output.
Due to the limited number of pins either the low-side or the high-side is combined internally
and routed to Pin 5. Therefore you have to connect both loads as shown below if you want
to use both switching outputs.
