Explanation of the summary output function in case of 0-sheet, 1-sheet, 2-sheet:
If the equipment is operated in the sequencer mode (program with several sensors, e.g. 1+2), then
the measurement results are issued as "summary output". The following priorities are assigned:
•
If one or several of the sensors issue the double sheet signal (2-sheet), then the "summary
output" is 2-sheet
•
If only the 1-sheet is present, then the "summary output" is 1-sheet
•
Otherwise the "summary output" is 0-sheet
If the results of individual sensors are required, then interrogate bytes 12-23.
