Normal Operation
In normal operation the display shows the position of the line or the edge as described in
section 8.3
. If the line or edge is missing none LED will shine. Longer unintended line
interruptions are recognised by the DLS2 and it sends a special signal to the web guide
controller. In such a case the controller blocks the steering frame at the actual position
until the line is recognised again.
Note
In web guiding systems all equipped with FMS components and a DLS2 sensor it may
happen that the web guide controller blocks the steering frame. This protective
function is activated when the line is interrupted and impossible to be detected.
The DLS2 generates at unintentional line interruption an alarm signal that can be
used to shutdown the production line preventing the steering frame skittering away
and creating material loses.
