Use the ► button to navigate the digits, and the ▲▼ buttons to change the digit value.
Changes can be abandoned at any time by pressing the button. When the desired digit
has been set press the ENTER button, the value will be written into the panel’s non-volatile
memory, and the system will return to the parameter list.
8.3.2 Parameter 1 – Field Muted Button Functionality
In the Mode Select screen the FIELD MUTED button is used to place the Sentinel Plus
system into Field Muted mode. Field Muted mode disables the optical protection and
restricts the maximum pressing speed to safe speed, as described in Section 3.7.
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.).
This parameter has three options (also described in Section 6.6), that sets the functionality
of the FIELD MUTED button.
• ENABLED. The button functions as normal.
• DISABLED-ON. The Sentinel Plus system is permanently locked in Field Muted
Mode.
• DISABLED-OFF. The button is disabled, and Field Muted mode cannot be
selected.
Use the ▲▼ buttons to navigate the options. Changes can be abandoned at any time by
pressing the button. When the desired option has been selected, press the ENTER
button, the value will be written into the panel’s non-volatile memory, and the system will
return to the parameter list.
8.3.3 Parameter 2 – Mute Stop Button Functionality
In the Mode Select screen the MUTE STOP button is used to put the system into Stop at
Mute mode, as described in Section 3.8. This parameter has three options (as described in
Section 6.7), that sets the functionality of the MUTE STOP button.
• ENABLED. The button functions as normal.
• DISABLED-ON. The Sentinel Plus system is permanently locked in Stop at Mute
Mode.
• DISABLED-OFF. The button is disabled, and Stop at Mute mode cannot be
selected.
Use the ▲▼ buttons to navigate the options. Changes can be abandoned at any time by
pressing the button. When the desired option has been selected, press the ENTER
button, the value will be written into the panel’s non-volatile memory, and the system will
return to the parameter list.
8.3.4 Parameter 3 – Mute Off-Set Distance
The Mute Off-set parameter can be used to raise the mute point by up to 65mm from the
defined mute point. This is used to prevent irregularities in the work piece (such as bends or
rivets) from causing false obstructions. Optical protection will be disabled at the mute off-set
height, and the machine will be forced into safe speed.
This value is measured in millimetres (mm), and can be set between 0 and 65mm (0000 –
0065 for the parameter screen value).
