Operation
The EVO 150 may be configured for a wide variety of applications, but most configurations share
the same basic operating procedure:
1) Press the SERVO-CENTER button and wait for the web guide to drive to the center of travel.
2) Thread the web through the machine.
3) Position the sensors.
One edge detector: Place the detector near the edge of the web. Move the detector towards
the web until its null indicator LED turns off. Note: The scribed lines on the edge detector
indicate the approximate location of the detector’s guide point.
Two edge detectors (centerline guiding): Press the EDGE A button. Place detector A near
the edge of the web. Move detector A towards the web until its null indicator LED turns off.
Press the EDGE B button. Place detector B near the opposite edge of the web. Move
detector B towards the web until its null indicator LED turns off.
Note: The scribed lines on
the edge detector indicate the approximate location of the detector’s guide point.
Digital line guide: Position the sensor so that it is approximately centered over the
registration line or edge. When it is positioned correctly an indicator dot will appear in the
display under the line or edge you want to track. Refer to page 60 for more information about
operating the line guide.
4) Press the EDGE A, EDGE B, or LINE button. For Centerline mode (centerline guiding), press
the EDGE A and EDGE B buttons simultaneously.
5) Press the AUTOMATIC button. The system will now guide the web.
