Operating Instructions: Photoelectric Blocking - Bravo
Functionality
The Bravo Photoelectric Blocking Device is to be used to add additional safeguard functionality to an existing machine
guarding or access point that is fitted with a Light Curtain or similar Photoelectric or Sensing safety device.
The Bravo device consists of a Blocker Plate, a Personnel / Safety Key and a Padlockable Dustcover (See Fig.1 and Fig.2).
The Blocker Plate is directly linked to the operation and removal of the Personnel / Safety Key such that when the Personnel /
Safety Key is rotated clockwise the Blocker Plate also rotates into an Engaged position. The Engaged position of the Blocker
Plate is designed to block and interrupt the beam or signal of an associated Light Curtain or similar Photoelectric sensing
device.
Once the Blocker Plate is in the Engaged position the Personnel / Safety Key can be removed. The removal of the Personnel
/ Safety Key traps the Blocker Plate in its Engaged position until the Personnel / Safety Key is returned and rotated
anticlockwise back to its original position.
With the Blocker Plate in the Engaged position and the Personnel / Safety Key removed, Padlocks can be added to the
Padlockable Dustcover of the Bravo device for additional Lock-Out functionality. The addition of padlocks to the Padlockable
Dustcover will prevent the Personnel / Safety Key from being re-inserted therefore further retaining the Blocker Plate in its
Engaged position.
Blocking a Light Curtain or similar Photoelectric Sensing device:
• Rotate the Personnel key of the Bravo device clockwise.
• This will rotate the Blocker Plate to its engaged position.
• The Personnel Key can now be removed to trap the Blocker Plate in its engaged position.
Unblocking a Light Curtain or similar Photoelectric Sensing device:
• Raise and open Padlockable Dustcover of Bravo lock barrel.
• Be aware that any padlocks or Lock-Out measures having been used on the Padlockable Dustcover must be removed
before the Dustcover can be opened.
• Insert and rotate the Personnel Key anti-clockwise.
• This will rotate the Blocker Plate to its retracted position.
