9.4
Operation in Normal Mode
Refer to
Section 3.4
for a detailed description.
Refer to
Section 6.5
for selecting guard modes.
•
Ensure that it is understood what happens when the system runs in normal mode.
•
The process must be understood and demonstrated.
•
Ensure it is understood that the protecting laser field is muted after the first obstruction
and that the Mute lamp remains permanently lit to indicate this status. Explain the
sensor blanking function of the receiver rear sensors.
9.5
Tray / Tray 2 / Back Gauge mode
Refer to
Section 3.5
and
Section 3.6
for detailed descriptions.
Refer to
Sections 6.5
and
6.9
for selecting/exiting these modes.
•
Explain and demonstrate how this process is useful in box and tray type bending.
•
Get the operator to go into and come out of the Tray modes 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 mode.
•
In Tray 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.
•
Explain the difference between Tray and Tray2 mode, including the need for a
confirmation pedal press at the beginning of each stroke.
•
Explain the reason for Back Gauge mode, and the elevated rear sensor mute height
(16mm).
9.6
Field Muted Mode
Refer to
Sections 3.7
for a detailed description.
Refer to
Section 6.6
for selecting/exiting Field Muted mode.
•
Demonstrate this function and ensure the operator understands that the laser protection
will be switched off and the machine will only operate in safe speed while being used in
this mode.
•
Explain that the system will 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.
Warning: NO OPTICAL PROTECTION IN FIELD MUTED MODE
In Field Muted mode, all optical guarding is deactivated. Although the Sentinel
Plus Press Brake Guarding System ensures that the machine does not exceed
safe speed in this mode, particular caution must still be exercised.
Entry to Field Muted mode can be password protected, and should only be
used by suitably trained personnel, and only in exceptional circumstances
(changing tools, maintenance, etc.).
9.7
Stop at Mute Mode
Refer to
Section 3.8
for a detailed description.
Refer to
Section 6.7
for selecting/exiting Stop at Mute mode.
•
Explain and demonstrate the Stop at Mute function.
•
Explain how this mode can be used when forming complex parts or parts with deep side
flanges to increase machine productivity.
