Fortress Technologies Osbourn PBL2A-1-1-CLSL-MP1 Operating Instructions Manual

Operating Instructions: Photoelectric Blocking - PBL
Description
Fortress' PBL prevents unexpected start-up in areas safeguarded
by light curtains, an individual takes the safety key when entering
the area and while they have that key on their person the light
curtain remains blocked and therefore the protective stop function is
maintained, this ensures the hazard cannot be reset or restarted until
the key is returned to the unit. PBL provides the same peace of mind
for an operator entering past a light curtain as a safety key or interlock
blocking device does with physical guards. Additional padlock points
on the dustcover allow any subsequent individuals entering the area
to apply their own means of control to the device.
As a purely mechanical component complete with an integrated
mounting plate it is easily retrofitted or added to an existing system,
with a compatible light curtain, without the need for wiring or
programming.
