Target Sensor
The target sensor detects targets on the conveyor as they approach the slicing heads. When a target
is detected a start signal is sent to the controls on the slicer which causes the slicer to stroke when
the target reaches the slice zone. Sensitivity of the sensor must be adjusted so it correctly detects
targets as they pass under it. Two different sensors are used on slicers--the Banner Sensor and the
Fiber-Optic Sensor. Adjustments for each of them are described below.
Banner Sensor
The red LED next to the sensitivity control indicates when a target is being detected. The
sensitivity must be set so that targets are accurately detected without either of the following
conditions occurring:
1. Continuous or overdetection (sensitivity too high).
2. Intermittent or underdetection (sensitivity too low).
NOTE: Eye sensitivity should be set as high possible without detecting false targets.
Decrease the numbers in the eye sensitivity control to reduce the sensitivity and increase the
numbers to increase the sensitivity. The red LED above the eye sensitivity control lights
whenever the eye is sensing a target.
The sensitivity needs to be increased if targets are not being "seen" and decreased if the
conveyor belt is being "seen".
For initial adjustment, find the high end setting by adjusting the knob higher (clockwise) until
the red light comes on. The eye is now sensing the conveyor. Then turn the adjusting knob
lower (counterclockwise) until the light just goes out. The eye is now at the low setting and
focused just above the conveyor. Set the sensitivity between the high and low end settings.
Fiber Optic Sensor
Sensor Installation
The sensor is positioned above the conveyor where it detects the targets onto which the
machine slices product. An amplifier is located inside the control enclosure. The
amplifier has four switches that are set before shipment. These settings are:
Switch Setting
Max-Set-Run Run
L. On-D. On L. On
Norm-Hi Norm
Off Dly-Off Off
Two fiber optic cables run from the sensor to the amplifier. One cable has a solid fiber;
the other a multi-stranded fiber. The solid fiber cable should be inserted into the hole with
an arrow pointing out from the side of the amplifier. The multi-stranded fiber cable should
be inserted into the hole with the arrow pointing in from the side of the amplifier.
