options range from bypassing individual channels to bypassing the entire system.
Section 6.7.3.1 Channel Bypass
Individual channels can be bypassed by changing the Channel Setting bypass setting from No to Yes.
Section 6.7.1.5 explains how to bypass an individual channel.
Individual channel bypass is not automatically removed when the press mode is switched to Production.
If the system is configured for automatic un-bypass when the press mode changes from Setup to
Production, individual channels bypassed in the Channel Setting screen, will not be un-bypassed.
The individual channel bypass is volatile. If an individual channel is bypassed in the Channel Settings
screen and power is removed from the unit, the channel will be un-bypassed on power-up.
Section 6.7.3.2 System Bypass
If configured for System Bypass, the Die Protection screen will display the BYPASS ON/OFF softkey.
Control access must be gained by the user before this key can be used. When the system bypass is
switched to On, the entire Digital Die Protection and Process Monitor is switched off. To remove the
bypass and return the system’s monitoring functions, the user can again select the BYPASS ON/OFF
softkey.
In addition to the manual removal of bypass, the unit can be configured to automatically switch off
bypass when the press mode is switched from Setup to Production. This Auto Un-bypass in Production
Mode configuration option must be selected as described in Section 6.6.4.
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 6.7.3.3 Stroke Limited Bypass
If configured for Stroke Limited Bypass, the Die Protection screen will display the BYPASS “X”
STROKES softkey. Where “X” is the programmed number of strokes that the unit will be bypassed.
When the stroke limited bypass is switched on, the units monitoring functions will be turned off for the
number of press strokes displayed. As the press strokes, the System Status will display the remaining
number of strokes. In addition to the number of strokes limit, a timer may also be programmed to limit
the time that the stroke limited bypass remains in effect. Stroke limited bypass will be removed when
the number of strokes is reached or when the time times out, whichever occurs first.
Stroke Limited Bypass can be removed by selecting the CANCEL BYPASS softkey. In addition, the
unit can be configured for automatic removal of Stroke Limited Bypass when the press mode is switched
from setup to production. This Auto Un-bypass in Production Mode configuration option must be
selected as described in Section 6.6.4.
The automatic un-bypass feature only removes the Stroke Limited 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 Stroke Limited Bypass.
