#CMT# #/CMT# Printing machine comprises a processing unit for processing the measuring signal from sensors (14) so that when the measuring signal reaches or exceeds a first boundary value for a powder material concentration or amount, the processing unit generates a warning alarm. When the measuring signal reaches or exceeds a secondary boundary value for a powder material concentration or amount, which is larger than the first boundary value, and/or a defined time period has past after the warning alarm has sounded without the measuring signal falling below a third boundary value, the processing unit switches off the drying units (12, 13) of the printing machine. #CMT# : #/CMT# Preferred Features: The third boundary value corresponds to the first boundary value or is smaller than the first boundary value. #CMT#USE : #/CMT# Printing machine used as a sheet-fed printing machine. #CMT#ADVANTAGE : #/CMT# The machine operates with improved safety. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the printing machine. 10 : Bracket 11 : Transport part 12,13 : Drying units 14 : Sensors. |
