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.

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".
