Step 4
Make electrical connections as follows:
* Input Power ( 28 VDC ): The LS-3030 is an ANALOG OUTPUT device with a 28
VDC power input on the BLACK wire and producing a 4-20 mA current on the white wire.
This output can be used in conjunction with a computer monitoring system to indicate belt
speed in FPM. The output is a standard 0-3 VDC analog output: OFFSET = 0, GAIN is
dependent on roller size and the number of targets. Contact factory for further assistance in
using this feature.
Step 5
Now that the LS -3030 has been mounted, it can be calibrated. Connect the Multimeter in
line with the neutral and set the meter to read mA.
With the belt off the multimeter should read 4 mA on the output. If not, locate the zero
potentiometer. Using screwdriver, rotate the pot. counterclockwise till the multimeter reads 4 mA.
Now that the Zero Calibration has been set it is time to turn the belt on and adjust the span. With the
belt operating under normal conditions, the multimeter should read 12 mA. If not, locate the span
pot, and rotate the adjustment until the multimeter read 12 mA.
The LED, located between the two pots. will illuminate only when the target moves across the sensor
head of the Little Speedy.
target distance should be
between 1 / 8 to 3 / 8.
