Explanation of summary output 0-sheet, 1-sheet and 2-sheet:
If the unit is operated in the sequencer mode (program with more sensors e.g. 1+2+3), the measurement result is formed as
summary output. Only the active sensors are included.
2-sheet
is issued if at least one sensor detects 2-sheet.
1-sheet
is issued if all sensors detect 1-sheet.
0-sheet
is issued if no 2-sheet is detected but at least one sensor detects 0-sheet.
If the results of individual sensors are required, then interrogate bytes 12-23.
1)
If a fault occurs at the equipment an operator intervention is required e.g. memory error, low or missing voltage.
2),3), 4)
Footnotes see next chart “Byte 12 to 14”
5)
At R1000 systems with multiple measuring points, these outputs are issued as "summary output" for all measuring points;
as this equipment has only one measuring point available, the result of the measuring point 1 will be outputted.
6)
This function is implemented only in L20-3-XX-S (L20-XX-S in preparation).
