6.2.1 Explanation of summary output 0-sheet, 1-sheet and 2-sheet:
If the unit is used in sequencer-mode (more than 1 sensor in a program e.g. 1+3+4), the
measurement result is formed as summary output. The priorities are:
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.
Truth table for summary output
Sensor 1 Sensor 2 Sensor 3 Sensor 4
2-sheet is issued if:
2-sheet any condition
any condition 2-sheet any condition
any condition 2-sheet any condition
any condition 2-sheet
1-sheet is issued if:
1-sheet 1-sheet 1-sheet 1-sheet
0-sheet is issued if:
0-sheet 0-sheet / 1-sheet
0-sheet / 1-sheet 0-sheet 0-sheet / 1-sheet
0-sheet / 1-sheet 0-sheet 0-sheet / 1-sheet
0-sheet / 1-sheet 0-sheet
The results of the separate sensors are available in the bytes 12-23 and can be used as required.
6.2.2 Signal „Enable“
The signal ENABLE is always 24V active
The signal is LOW (0V)
• during system operation via keyboard
• in case of system fault
• during a system test
The signal is HIGH (24V)
• when the system is operational
6.3 Timing diagrams
Notes for the following diagrams and descriptions:
For all the following diagrams and explanations the output signal level of OUT1 to OUT3 has been
set to "+24 V" in config item 9: "Level 0-1-2".
In case of OUT 1 to OUT3 equal to "0 V" the outputs are inverted. “Level 0-1-2“ does not affect the
signal ENABLE OUT0.
HIGH Level at the outputs means relay is closed respectively opto coupler is low resistant.
LOW Level at the outputs means relay is open respectively opto coupler is high resistant.
