6.4
Operational conditions
6.4.1
Undisturbed operation
As long as no fault is detected in the measuring mode, no operator actions are required.
The unit measures continuously and sets the signal output according to the measurement result.
6.4.2
Detection of 0-sheet, 1-sheet or 2-sheet
As long as the measured value is within the range of 85% to 115% of the nominal value, the
system will detect 1-sheet.
If the measured value is outside the range, the system will then detect 0-sheet (no sheet)
or 2-sheet (double sheet).
•
The associated LED (0-SHEET, 1-SHEET, 2-SHEET) will light up accordingly.
•
The associated signal output will be set to low resistance (active).
•
The signal outputs 0-SHEET, 1-SHEET, 2-SHEET will deliver a switch voltage only if an
external positive voltage (max. +24V, max. 50mA) is applied to the COMMON input (terminal 8).
6.4.3
Operational disturbances
If situations arise during operation, which the system recognizes as "operational faults", the system
reacts with the "FAULT" LED lighting and issues the assigned fault message (if any).
•
If the fault condition was caused by the machine PLC, the signal outputs for 1-sheet
and 2-sheet are set at the same time. The illogical constellation of 1-sheet and 2-sheet will
indicate the fault condition to the machine PLC. Depending upon the PLC programming an
appropriate reaction can then be initiated. Recognizable faults are to be eliminated and the
function should be performed again.
•
If the fault condition was caused by the operator or by the system, the operator must react
according to the measures explained in the fault table.
•
If the fault cannot be assigned, restarting the system by recycling power may eliminate the fault.
6.4.4
Functional check
If the system does not detect double sheet conditions though a Teach-In was freshly performed,
the sensorics might (according to material properties) work at the detecting limit.
First, the mechanical sensor settings should be checked, as well as the working range (according
to sensor data).
If the mechanical circumstances are correct and the sensor is operated within the permissible
range, the upper limit might be improved by changing the upper threshold. For doing so, refer to
section "changing the thresholds".
