LINK Systems OmniLink II Press Automation Control - Manual (Page 128)

August 30, 2002 Manual Version 1.0 6.23
When bypassed, the system will halt all monitoring functions. See Section 6.7 for more information
concerning bypass. After the number of strokes has been completed or after the maximum bypass time
has been exceeded, the bypass condition will be removed.
Section 6.6.3 System Bypass Allowed
If the System Bypass Allowed parameter is set to Yes, the BYPASS ON/OFF softkey will appear on the
Die Protection screen. Any user who has been granted access to this system bypass, can do so by
selecting this softkey. See Section 6.7 for more information concerning bypassing. By selecting this
softkey again, the user can remove the system bypass. If this parameter is set to No, the BYPASS
ON/OFF softkey will not appear on the Die Protection Screen. The only means of bypassing the Digital
Die Protection and Process Monitor will be automatic bypass and stroke limited bypass.
Section 6.6.4 Auto Un-bypass in Production Mode
If the Auto Un-bypass in Production Mode parameter is set to Yes, the Digital Die Protection and
Process Monitor will automatically remove any bypass when the press operating mode is changed from
setup to production. The automatic removal of bypass will prevent the system from being inadvertently
left in bypass when changing from setup mode to production mode. This automatic un-bypass feature
will remove the bypass when the press mode is changed to production mode from setup mode. This
feature requires that the Use Mode Input Setting be set to yes and that the Setup Mode input be
used. See Section 4.2.1.6. If the Auto Un-bypass in Production Mode parameter is set to No, there will
be no automatic un-bypass.
The automatic un-bypass feature only removes the bypass when the press mode changes from setup to
production. Once in production mode, any user who has been granted access to do so can again select a
bypass.
Section 6.6.5 Restricted/Unrestricted Die Protection Channels
The RESTRICTED UNRESTRICTED softkey on the Die Protection System Configuration screen can
be used to display the Die Protection Restricted screen. This screen allows for selected channels of the
digital die protection and process monitoring system to be restricted. When a channel is restricted, it can
be viewed but not changed by the operator, and it will not be affected by job recalls. Once a channel is
restricted, it will retain all settings that were programmed when the channel was set to restricted. The
channel setting cannot be changed while restricted. If a job is recalled the restricted channel setting will
not change, even if the restricted channel’s settings are different in the recalled job. The user has the
option to restrict or unrestrict any channel. In order to make changes to a restricted channel; the
restriction must be removed, the change entered, and then again set the channel to restricted.
Section 6.7 Operation
The Digital Die Protection and Process Monitor screen is shown in Figure 6.22. Various items on this
screen are referenced to sections of this manual.
