SF2 Series
Instruction Manual
22
The following connection diagram shows how the SF2 light curtain can
be connected with force-guided relays (MPCE).
User-supplied fuse.
For normal operation mode, the TEST wire has to be
connected to 24 Vdc by a NC button. If the wire is not
connected or connected to 0VDC, the SF2 light curtain
enters in break condition.
The MPCE coils must be suppressed.
Thanks to these contacts, the safety light curtain
controls the MPCE devices. If one of the MPCE devices
is blocked in a closed condition, the light curtain’s power
supply is removed and the second MPCE device blocks
the machine if the beams are interrupted or when the
TEST procedure is carried-out.
