Figure 3-6: Tray/Box Mode Operation
If the middle sensor is obstructed when the pedal is pressed then the tools will not close. The
operator must release and press the pedal again. 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.
3.5.2 Tray Mode - When the Tools are Closing
If there is no obstruction to any of the sensors then the system operates as it does in Normal
Mode (refer
Section 3.4
). If the front and/or rear sensors are obstructed then the tools will
stop closing and the message
Front/rear sensor blocked – RELEASE FOOT PEDAL
is displayed
.
The operator must release and press the pedal again, at which point the system deactivates
the front and rear sensors and allows the tools to close in high speed (the middle sensor must
remain clear) until the bend is completed. If the middle sensor is obstructed when the pedal
is pressed then 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.
3.5.3 Tray 2 Mode
Tray 2 mode is a variant of the standard Tray/Box mode. As in Tray/Box mode, the front and
rear sensors of the guarding system are disabled, so that complex shapes can be bent. The
operation of Tray/Box 2 mode differs from standard Tray/Box mode in the following details.
1. Before every stroke the operator must acknowledge that they are in Tray 2 mode. The
first pedal press does not close tools, but generates the message
TRAY 2 CONFIRM –
RELEASE FOOT PEDAL
, alerting the operator that Tray 2 mode is selected. This
message will be displayed until the pedal is released. The operator now has three
seconds to press the foot pedal and perform the stroke.
2. On the second pedal press the beam moves down in high speed with the front and
rear sensors muted for the entire stroke. An obstruction to the front or rear sensor will
not halt the machine and it will continue down in high speed until the mute point. If
this second pedal press does not occur within the three second timeout, the cycle is
reset, and Step 1 above must be repeated.
The middle sensor is always active, regardless of which Tray/Box mode is selected. It guards
through the entire stroke (until the mute point), as described in
Sections 3.5.1- 3.5.2 above.
