Notes on connections

To ensure the correct operation of the PSEN safety device, please
note the following:
•
Use screened cable (accessories) to connect the transmitter and
receiver.
Fig.14 shows how to connect the transmitter/receiver correctly.
•
Under no circumstances should the connection cables come into
contact with or be laid in proximity to cables that generate strong
electromagnetic interference (e.g.: motor feeds, inverters etc.);
these could compromise the device's ability to function.
•
The TEST/START input should be connected to the supply voltage
on the ESPE via a button with a N/C contact. The test should be
performed manually (by pressing the button) at least once a day in
order to check the proper operation of the safety device.
•
Multicore cables may not be used to connect the outputs of more
than one light curtain.
•
The TEST/START button must be positioned in such a way that the
operator has a clear view of the protected area when reset, test or
override procedures are in progress (see Ch. 6 "Operating mode").
