Description
The two lightposts that mount on each end of the Bravo rear:
•
Transmitter lightpost (left rear) projects the light beams across the
Bravo left side opening to the left mirrorpost, which reflects the light
beams across the front opening.
•
Receiver lightpost (right rear) detects the light beams reflected across
the Bravo right side opening.
The lightposts are connected to the safety interlock circuit through the
junction box. The lightposts detect any disruptions in the light beams. A
column of LEDs on the lower front of each lightpost indicate the light
curtain status.
•
LED lights turn green when the light beams are aligned and no
disruptions are detected.
•
LED lights turn red if the receiver does not detect the light beams.
Improperly aligned mirrorposts or disruptions in the light beams
cause the LED lights to turn red.
The two mirrorposts that mount on the front left and front right corners
of the Bravo base.
•
The left front mirrorpost receives the light beams projected across the
left side opening from the transmitter lightpost, and then reflects the
light beams across the Bravo front opening.
•
The right front mirrorpost reflects the light beams across the right
side opening to the receiver lightpost.
A clear plastic shield that attaches to the two front mirrorposts to
prevent access at the front between the top of the light shield and the
Bravo top.
A ventilated metal shield that attaches to the two front mirrorposts to
prevent access at the front between the bottom of the light shield and
top of the Bravo deck.
Clear plastic shields prevent access through the upper left and right side
openings above the light shield.
A clear plastic shield that prevents access through the rear opening of
the Bravo platform. The shield has three access windows for routing
cabling and tubing off the deck.
A rear shield might not be required if the Bravo rear opening is not
accessible to operators.
When the light beams are aligned, the light curtain generates an invisible
light shield that spans across the Bravo side and front openings.
The box that provides the connections for the Bravo emergency- stop
pendant and the transmitter and receiver lightposts. The following figure
shows the front view and rear view.
