Laser Classification and Warnings
Warning: CLASS 1 LASER DEVICE
The LZS-005-R laser transmitter emits CLASS 1 laser light approximately
50mm x 80mm. Do not stare directly into the lasers or the transmitter window.
CLASS 1 LASER
Warning: CLASS 3B LASER RADIATION: DO NOT OPEN OR TAMPER
WITH
THE LASER TRANSMITTER
The LZS-005-R laser transmitter contains no user serviceable components. Do
not attempt to tamper with or dismantle the laser transmitter as this will void the
product warranty, and may expose you to the internal laser emitter CLASS 3B
LASER RADIATION that has the potential to cause eye damage.
DANGER
VISIBLE LASER LIGHT, AVOID EXPOSURE
TO BEAM, CLASS 3B LASER PRODUCT
WAVELENGTH 532nm-680nm
MAX POWER < 500mW

LZS-005-R Block Laser
The Sentinel Plus system employs a LZS-005-R Block Laser transmitter and receiver. The
transmitter projects a square beam of laser light approximately 80mm wide by 50mm high
that surrounds the upper tool. This creates a silhouette (or shadow) of the upper tool on the
receiver window, as shown in
Figure 3-3
.
When the system is first started the receiver performs an automatic tool alignment, where it
analyses the receiver image and locates the position of the tool tip. From this it determines
the optimum position for the guarding area around the tool tip.
As the tools close in high speed the LZS-005-R receiver first detects the presence of the
material and then progressively mutes the guarding around the tool tip row by row, until the
guarding is completely muted when the tool tip is 2mm above the material. The slow speed
point of the press must be set so that the press beam has decelerated from high speed to
pressing speed by the time the tool tip has reached the mute point.
Note:
The actual slow speed point is dependent upon the performance of the press
brake. The Sentinel Plus system is optimised for high speed performance press
brakes.
