The system provides a general interlocking bypass mode (Main menu/
Control/Interl bypass) that overrides all interlocking signals. Activation of
the interlocking bypass mode activates the interlocking enable signals of all control
objects. Thus, all local control actions are possible and the enable signals
(OPENENA, CLOSEENA) of controllable objects are not checked while the objects
are commanded. As long as the mode is active, the interlocking LED on the HMI is
blinking red. Additionally, the assisting window of the display will indicate the
special condition.
