4.1. Notes on connections

To ensure the correct operation of the PSEN op2H safety device,
please note the following:
•
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.
•
Multicore cables may not be used to connect the outputs of more
than one light curtain.
•
The TEST input should be connected to the supply voltage of the
receiver (RX) 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.
•
If the TEST input is connected to 0 VDC when the ESPE is
switched on, the safety curtain will switch to guard mode (BREAK
condition) (see Ch. 7 "Diagnostic function").
•
The TEST button must be positioned in such a way that the
operator has a clear view of the protected area when test
procedures are in progress (see Ch. 6 "START mode").
•
With protection class 3, earthing of the transmitter and receiver is
not permitted; SELV/PELV power supplies must be used.
•
If evaluation devices or a supply voltage
are connected without safe separation,
the light barrier must be operated in
protection class 1. In this case, the
transmitter and receiver must be labelled
