Laser Classification and Warnings
Warning: CLASS 1 LASER DEVICE
The LZS-2 block laser transmitter emits a CLASS 1 laser approximately 48 mm
x 30 mm. Do not stare directly into the lasers or the transmitter window.
Warning: CLASS 3R LASER RADIATION: DO NOT OPEN OR TAMPER WITH
THE LASER TRANSMITTER
The LZS-2 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 3R
LASER RADIATION that has the potential to cause eye damage.
3.3.3
Mute Point
The mute point must first be established so that the system will not treat the material being
formed as an obstruction. The mute point is automatically set at 2mm above the surface of
the material as the tools close for the first stroke. This mute point set-up can be initiated
whenever the tools are changed or the material thickness changes.
3.4
Normal Mode
This is the default mode at start-up. In Normal Mode both sensors (A, B) and all zones (front,
middle, rear) are active. When the foot pedal is pressed the system checks that the sensors
are clear and allows the tools to close in high speed. The machine then decelerates to
pressing speed just before the mute point. The sensors are automatically muted so the tool
opening is 6mm when the optical protection is no longer active and the bend can be
completed.
Note:
The Sentinel User Interface Panel displays the status of the machine, and any
action that is required by the operator. In the following sections the operator
messages are shown in the following format:

3.4.1
Obstruction Detection
–
From a Stationary Position
If any part of a sensor is obstructed when the pedal is pressed then the tools will not move
and the message
Sensors blocked
–
RELEASE FOOT PEDAL
will be displayed. The operator
must release and press the pedal again. If the sensors are clear then the tools will start
closing in high speed. If any sensor remains obstructed, the system will force the tools to
close in safe speed only with the optical protection muted and display the message
LASERS
INACTIVE
until the bend is completed. The sensors become active again once the tools are
opened.
