Output Current Transducer

FAQs

• Symptom: No output signal
  • Possible Solution: Check wiring connections and ensure proper setup of the sensor as per installation instructions.
• Symptom: Wrong output current
  • Possible Solution: Verify the selector switch setting matches the monitored current range and recalibrate if necessary.

PRODUCT INFORMATION

IMPORTANT WARNINGS

• Only qualified trade installers should install this product
• This product is not intended for life-safety applications
• Do not install in hazardous or classified locations
• The installer is responsible for all applicable codes
• This product must be installed in a suitable electrical enclo-sure

INSTALLATION

Disconnect, lock out, and tag out all power supplies during installation

1. Determine a mounting location for the sensor near the conductor to be monitored. The sensor should be located AT LEAST 1/2” from any uninsulated- ed conductor.
2. The sensor features a flexible coil that wraps around and allows the sensor to hang on the conductor if local codes permit. The enclosure is provided with 2 slots for securing the sensor using zip ties.
3. Wrap coil around an INSULAT- ED CONDUCTOR ONLY, 600VAC MAX to be monitored.
4. Wire the output of the sensor to a control panel analog input appropriate for the output type selected. See wiring examples. Tighten terminals to 3.5 in-lb.

SETUP

1. The Sensor is factory-calibrated to three ranges. No field calibration is required.
2. Move the selector switch to the desired factory-calibrated range. The selected range should be greater than the maximum expected monitored current.

WIRING EXAMPLES

PRODUCT APPLICATION LIMITATION: Senva products are not designed for life or safety applications. Senva products are not intended for use in critical applications such as nuclear facilities, human implantable devices, or life support. Senva is not liable, in whole or in part, for any claims or damages arising from such uses.

OPERATION

The RoFlexTM provides a universal output signal proportional to the monitored current. A switch allows field selection of desired ampreage range.

Typical load status applications include:

• Load trending
• Monitoring process motors and pumps
• Heater current monitoring
