Caution! Risk of danger
Safe operation can only be guaranteed if the
transducer is used for the purpose for which it was
designed and within the limits of the technical speci-
fi cations When this symbol is used, it means you
should consult all documentation to understand the
nature of potential hazards and the action required to
avoid them.
Caution! Risk of electrical shock
When operating the transducer certain parts may
carry hazardous live voltage (e.g. Primary conductor,
power supply). The transducer should not be put into
operation if the installation is not complete.

INSTRUCTIONS
AS3 SERIES
AC Current Operated Switch w/Jumper
Selectable Range, AC or DC Output
Quick "How To" Guide
1. Run the wire you are monitoring through ap-
erture.
2. Mount the sensor to a surface if needed.
3. Connect output wiring.
A. Use up to 14 AWG copper wires.
B. Make sure the load matches the output
shown on the sensors' label (volts, amps,
AC/DC).
4. Adjust Setpoint
A. Chose correct range by positioning the
Range Jumper
B. Use the potentiometer to adjust the set-
point.
5. Confi rm Contact Operation
A. If the sensor has an LED, quick fl ash indi
cates current over the set point and output has
tripped, slow fl ash shows current under set point,
output is shelf state condition.
