SF2 Series
Instruction Manual
2
The microprocessors guarantee the check and the management of the
beams that are sent and received through the units: the
microprocessors – through some LEDs – inform the operator about the
general conditions of the light curtain and about eventual faults (
see
section 7 “Diagnostic functions”
).
During installation, two yellow LEDs facilitate the alignment of both
units (
see section 5 “Alignment procedures”
).
As soon as an object, a limb or the operator’s body accidentally
interrupts the beams sent by the emitter, the receiver immediately
opens the OSSD output and blocks the machine (if correctly connected
to the OSSD).
