Web Control Systems
Edge Position Control Systems(Sensors) LINE FOLLOWER HEAD LH110 Overview |　 Feature |　 Specifications |

Overview

The LH110 can be used on slitting machines as the sensor to optically detect register lines or patterns printed on the web. In combination with an amplifier (Liteguide Controller AE1000, AE900L or Webguide Amplifier EH321A), the LH110 can form an EPC (Edge Position Control) and LFC (Line Follower Control) system.

Feature Easy to understand display and functions

No edge/line changeover required

When detecting a wide width line or pattern edge, there is no need to switch between the edge and line.

Polarity switching not required
When the gradation of the web material and line, (or that of the left and right edges) is reversed, there is no need to switch control output polarity.

Gain readjustment not required
The change in output voltage for line (edge) deviation is not influenced by line width or color; therefore, once the gain of the controller is set during a trial run, it is not necessary to readjust the gain.

Position signal retention function
During the interval when a line (edge) leaves the view field to when it returns, the position signal generated immediately before the line (edge) leaves the view field is retained and output. Therefore, a follow-up operation can be performed when the meander speed of a web is fast and

LED indication of optimum attachment position of detector
An LED indicator lights when the focal distance is correct and the mounting interval between the path line and detector are appropriate.

Line (edge) position indicated by LED
Integral action is the standard control operation; however, when used in combination with a position transmitter, the LH110 is capable of proportion action and integral + proportional action. You can choose the best control action for the machine that you are using.

An LED indicator lights when the detected edge is at the center of the view field.
When the device is connected to a controller that has an actuator lock contact input, (in cases of intermittent lines) the actuator is locked when the break in the line is detected and follow-up operation is stopped until the next line appears. Note: The position signal retention function is not available when an actuator lock signal output is used.
