Refer to the standard ordering information below:

A WARNING: This product is not intended to be used for Life or Safety applications.

This product is not intended for use in any hazardous or classified locations. The CTS-V and CTP-V Series Current Sensors must be used on Insulated Conductors Only!

A WARNING: Electrical shock hazard. Disconnect and lock out all power sources before installation as severe injury or death may result from electrical shock due to contact with high voltage wires.

Make sure that all installations are in compliance with all national and local electrical codes. Only qualified individuals that are familiar with codes, standards, and proper safety procedures for high-voltage installations should attempt installation.

The current sensor will not require external power, since the power for the current sensor is induced from the conductor being monitored.

The current sensor may be mounted in any position using the two #8 x 3/4″ Tek screws and the mounting holes in the base, or snapped directly on to the 35mm DIN rail. Leave a minimum distance of 1″ (3 cm) between the current sensor and any other magnetic devices such as contactors and transformers.

Press down on the side tab and swing the top of the unit up to open the split core current sensor.

Press down firmly on the cover to close the current sensor. An audible “click” will be heard as the tab slides over the tongue on the base.

CAUTION: Mating surfaces of the magnetic core are exposed when the sensor is open.

Electrical contact grease, present on the cores to prevent corrosion, can capture grit and dirt if care is not exercised. Operation can be impaired if anything prevents good contact between pole pieces. Visually check the mating parts of the core before closing the current sensor.

The amperage range selected represents the maximum current that can be applied to the conductor being monitored; Do not exceed this maximum current!

All current sensors with selectable ranges will have the range selection jumper factory set on the high range.

For models with field selectable amperage ranges, select the correct amperage range using the range selection jumper.

We recommend the use of a two conductor 16 to 22 AWG shielded cable, copper wire only, for all Analog current sensor installations. A maximum wire length of less than 30 meters (98.4 feet) should be used between the current sensors and the Building Management System or controller.

NOTE: When using a shielded cable, be sure to connect only one (1) end of the shield to ground at the controller. Connecting both ends of the shield to ground may cause a ground loop.

When removing the shield from the sensor end, make sure to properly trim the shield to prevent any chance of shorting.

The current sensor terminals are polarity sensitive and represent a linear 0 to 5 or 0 to 10 VDC output signal. Tighten the screws at the terminal block connections to the recommended torque of 0.5 to 0.6 Nm (4.43 to 5.31 in-lbs.).

Verify that there is current flowing through the conductor being monitored with a clamp-on current probe. The power for the current sensor is induced from the conductor being monitored.

Check the polarity of the circuit.

Verify that the terminals are screwed down, wires are firmly in place.

Disconnect the wires from the current sensor output. Measure the voltage across the current sensor output with a Voltmeter to verify that the sensor is working properly.

Verify that the wires are terminated properly.

In areas of high RF interference, shielded cable may be necessary to stabilize signal.

If you suspect that the current sensor is not reading within the accuracy specifications, please contact the factory for assistance.

Visually check the mating parts of the core to ensure there is no debris between the split contacts (refer to Figure 2 in the product documentation for CTP-V series).

Remove all debris or dust manually and close the current sensor.

Continue to retest the sensor in your application.

To convert the current sensor output signal to a current reading (example provided for a 4-20mA output, where 4mA = 0 Amps and 20mA corresponds to the max current of the selected range):

Example: 12mA current sensor output signal

Total Span = 250 Amps (This is an example value for the selected range of the sensor)

Multiplier = (20mA – 4mA) / Total Span

If Total Span = 250 Amps, Multiplier = 16mA / 250 Amps = 0.064 mA/Amp

Current Reading = (Actual mA reading – 4mA) / Multiplier

For the example: (12mA – 4mA) / 0.064 = 8mA / 0.064 = 125 Amps

At the end of their useful life the packaging and product should be disposed of via a suitable recycling center.

Do not dispose of with household waste.

Do not burn.
