A 1 minute Time-out period is foreseen in the TEACH-IN
procedure. At the expiry the system enters into the “Blanking
functioning failure” status
(see table).
The TEACH-IN procedure can be repeated during normal
device functioning.
The information acquired during TEACH-IN is memorised also
after device powering off.
A reset function of the TEACH-IN carried-out is not available. To
guarentee the same result, the TEACH-IN function has to be
repeated enuring that all beams are free.
An activation/deactivation function of the Fixed Blanking does
not exist. A tempory deactivation can be obtained leaving the
pin 3 (green) of the receiver’s M12 8-pole unconnected.
ATTENTION:
Fixed Blanking differently from Floating Blanking is
not signalled by the safety light curtain. Consequently all the
necessary precautions has to be taken before powering the
device:
Mount warning signs near the unprotected area to signal
possible risks.
Use protective stands and/or metal nets to avoid access,
through the Blanking zone, into the machine dangerous area.
