The EMERGENCY OFF state is only reset if IS "Acknowledge
EMERGENCY OFF" is first set and then IS "Reset" (DB3000 DBX0.7) is
set. It must be noted in this respect that IS "Acknowledge EMERGENCY
OFF" and IS "Reset" must be set together for a long enough period until
the IS "EMERGENCY OFF active" (DB2600 DBX0.1) was reset.
By resetting the EMERGENCY OFF state, the following happens:
• IS "EMERGENCY OFF active" is reset
• The controller enable is switched in
• IS "Position control active" is set
• IS "808D-Ready" is set.
• Alarm 3000 is cleared
• The part program processing is aborted.
