For products intended for the EU market, the following is ap-
plicable to the CE compliance of the product:
The ATS Series may comply with EN 61010-1 CAT III 300 V
max line-to-neutral measurement category. If insulated cable is
used for the primary circuit, the voltage rating of the measure-
ment category can be improved according to the characteristics
given by the cable manufacturer.
Use twisted pair for all connections.
24 Volt AC or DC Power Supply
Fuse at 5 amps maximum
Overvoltage Category I
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.

Single Range with Solid State Output and
Analog Signal
Quick "How To" Guide
1. Mount the sensor to a suitable surface if required.
2. Run the wire to be monitored through aperture.
3. Connect output wiring.
A. Use 30-12 AWG copper conductors only.
B. Ensure the power supply voltage matches the
model you are installing.
C. Energize the power to the sensor.
4. Adjust Setpoint.
A. LED will display the RMS value of AC current
which will cause the output to change state.
B. Turn the potentiometer until your target current
value is displayed.
5. Analog Signal Output
A. The analog outputs are powered from the sensor
power source.
B. The signal is proportional to the sensor range
selected.
