•
Ensure that it is understood what happens when the system runs in normal mode.
•
The process must be understood and demonstrated.
•
Demonstrate the difference between front, middle and rear sensor obstructions with regard
to the pressing beam retract function (if operational).
•
Ensure it is understood that the laser is muted after one or two obstructions (depending on
operation) and that the Mute lamp remains permanently lit to indicate this status. Explain
the sensor blanking function of the receiver rear sensors.

Refer to Sections 5.5 and 5.6 for detailed descriptions.
•
Explain and demonstrate how this process is useful in box and tray type bending.
•
Get the operator to go into and come out of Tray / Box mode themselves.
•
Explain that the mute point is retained when switching from normal to Tray / Box mode.
Also get them to change mute point in Tray / Box mode.
•
Make sure they understand that the front and rear sensors are muted after an obstruction,
but if the middle sensor is obstructed the laser will be muted for the remainder of the stroke.
•
Make sure the operator is aware of the 10 minute time limit set into Tray / Box mode and
that it ensures the machine cannot be left permanently in Tray / Box mode.

Refer to Sections 5.7 and 5.8 for detailed descriptions.
•
Demonstrate this function and ensure the operator understands that the laser protection will
be switched off and the machine will only operate in crawl speed while being used in this
mode.
•
Explain that the system will still monitor the machine speed and stopping performance.
Make sure the operator is aware that a responsible person should have access to the
password for enabling the field-muted mode button.
•
Show how to switch back to normal mode and explain that the mute point must be reset.
WARNING: NO PROTECTION IN FIELD MUTED MODE
In Field Muted mode, the optical sensing is deactivated. Although the LZS-003-HS
ensures that the machine does not exceed crawl speed in this mode, particular
caution must still be exercised.
The LZS-003-HS Operator Panel requires a password to enable the Field Muted
mode button. The password should only be available to suitably trained personnel.
Field Muted mode should only be used by suitably trained personnel and only
in exceptional circumstances (changing tools, maintenance, etc.)

Refer to Sections 5.9 and 5.10 for detailed descriptions.
•
Explain the stop at mute function. Show how the rear sensor is muted 10 mm above the
material to provide extra clearance for any back-gauge interference.
