for a detailed description of laser alignment.
•
Explain and demonstrate how to adjust the Transmitter and Receiver height.
•
Get the operator to adjust the brackets and check the alignment of the laser.
•
Demonstrate how the alignment cards are used to set the distance of the laser from the
punch ensuring that it is parallel.
•
Show how the receiver sensor status can be viewed by the indicator LEDs on the PGS-
3, the receiver and in the Sensor window of the User Interface Panel.
•
Explain that if the transmitter and receiver are not correctly aligned, the mute point can
be inaccurately detected when bending and that errors conditions can be generated that
will prevent normal operation.
9.9
Back Gauge Interference
Refer to
Section 3.6
and for a detailed description.
Refer to
Section 6.9

Running the System
•
Have the operator perform each of the main functions.
•
Using each mode of the system have the operator bend some test pieces of material
and also making sure to utilise the Tray / Box mode for a demonstration of the operation
during box bending.
•
Ensure the operator is aware of each mode they are in, and the different
Status/Action/Sensor windows in the Sentinel Plus panel display.
9.11
Dual Guarding Option
–
Light Curtain (if installed)
•
Demonstrate how to activate light curtain mode via the Sentinel Plus panel.
•
Demonstrate how the mute point position is determined by manually inching the tools
closed until the punch contacts the material (the Pinch Point or Zero Point).
•
Explain that an access code is required for the set and reset operations.
•
Explain that the mute point is set 6mm (1/4”) above the Pinch Point.
•
Explain how the light curtain is active and that the machine can still be operated in safe
speed if the light curtain is obstructed then the tool opening is more that 6mm (1/4 inch).
•
Have the operator select light curtain mode and set the mute point. Have the
operator select laser guarding mode again and reset the mute point.
