The following diagram shows the connection options for a PSEN op2H
safety light curtain with positive-guided relays (MPCE).
Fuse; not provided
In normal mode, the TEST input must be connected to +24 Vdc
via a button with a N/C contact. If this line is not connected or is
connected to 0 Vdc, the safety light curtain will switch to guard
mode (BREAK).
The relay coil must be fitted with appropriate suppression
elements
.
If the protected field is interrupted and one of the contacts
remains closed (contact welding), the supply voltage with the
wiring shown above is interrupted and the second contact
shuts the machine down.
