Adjusting the LRD2100
  • The adjustments on the LRD 2100 are marked maximum as ‘100’ and the minimum is marked as ‘0’.
  • Turning the adjustments past the maximum and or minimum will result in damage to the sensor.
  • Adjustments when first installed on a machine are seen below.
Step 1

Remove all material from sensor

Adjusting the LRD2100 Step 1

Step 2

Set GAIN to middle (50)

Adjusting the LRD2100 Step 2

Step 3

Turn the ZERO adjustment to where the ZERO light changes between on and off. It is not important whether it is on or off when complete, as long as it is close to where it changes.

Step 4

Add label material to sensor.

Adjusting the LRD2100 Step 4


Adjustments when Label Stock Is Changed

Usually None. The basic setting on the previous page (Gain at Midpoint) will work for most labels. Very small labels may require an increase in Gain. If, and ONLY IF, the new labels aren’t being detected correctly, use this procedure.

Step 1

Set GAIN to minimum (0)

Turn the GAIN button counterclockwise until it points to 0.

Adjustments when Label Stock Is Changed Step 1

Step 2

Adjust GAIN

Move labels through the sensor and increase GAIN until the OUT light just begins to flash as the gap moves through the sensor. Then, turn the dial one additional tick mark. Create some slack in the web and move one gap back and forththrough the sensor while adjusting.

Step 3

No Label Detected

If the sensor does not detect labels reliably, you may have label materials that require an LRD6300 or LRD8200. Contact your Lion Precision sales representative for more information.


Output and Mechanical Detail

Light/Dark switching is affected by the direction of label movement and the Output Polarity connection. Output descriptions seen here are for web direction indicated in the illustration and are reversed for web movement in the other direction.
