Warnings
Sensor body is connected to Ground.
Sensors must not be a�ached to voltages in excess of 30VRMS or 60VDC
All power must be off when installing the sensor.
Use of the equipment in any other manner may impair the safety and EMI
protec�ons of the equipment.
1. Remove all material from sensor.
2. Set GAIN ADJUST to maximum by turning at least four (4) turns clockwise.
3. Set ZERO ADJUST
Turn the Zero adjustment to where the Zero light changes between On
and Off. It’s not important whether it is On or Off when completed, as
long as it is close to where it changes.
4. It is recommended that you place a round black label (several are included with
the sensor) over the Zero adjustment to prevent unnecessary adjustment in the
future.
5. Set GAIN ADJUST to midpoint by turning two (2) turns counterclockwise
This setup will work with most labels and not require readjustment. The Zero may
have to be adjusted again if the baseplate or spacer is ever replaced or removed.
Usually None
. The basic se�ng above (Gain at center of its range) 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:
1.
Re-Set the Gain to center of its range
a. Turn the Gain adjustment at least 4 full turns clockwise
b. Turn the Gain adjustment 2 turns counterclockwise
Run and see if the sensor works correctly. If it does, the Gain had been adjusted and
needed to be re-centered. If it s�ll does not work correctly, then use this procedure
to fine-tune the Gain se�ng
1.
Set Gain to Minimum by turning it 4 turns counterclockwise
2.
Move labels through the sensor and increase GAIN (turn clockwise) un�l the
OUTPUT light ("EDGE" on older models) just begins to flash. If possible, it may
be easier to create some slack in the web and just move one gap back-and forth
through the sensor while adjus�ng.
3.
Turn the Gain adjustment another half-turn clockwise.
4.
If the sensor s�ll doesn't detect labels reliably, you may have label materials
that require an LRD6110 or LRD8200.
The OUTPUT light (EDGE on older models) indicates the sensor output. It will be in
one state (on or off) during the label and the other state during the gap depending
on the direc�on of the label movement and the connec�on of the Polarity Invert
wire (see next page for details).
The Zero light is for first-�me setup only and is meaningless during opera�on.
1.
For best results, web should ride against sensor baseplate, not “float” in the
gap.
The adjustments on the LRD2100 have a maximum of four (4) turns. If they are
turned beyond the end points, the adjustments will con�nue to turn without
damaging the sensor, but no further adjustment will occur.
Warning: Brown wire must be connected to +V or
Ground for reliable opera�on.
Warning: Gray wire (pin 5) must be connected to
+V or Ground for reliable opera�on.
