Senva products are not intended for use in critical applications such as nuclear facilities, human implantable device or life support. Senva is not liable, in whole or in part, for any claims or damages arising from such uses.CALIBRATION1. Adjust knob on sensor to motor full load amperage (FLA) as indicated on motor nameplate or overload protection device. (See Tech Tips for precise calibration procedure.)INSTALLATION1. Determine mounting location for the sensor near the conductor to be monitored. The sensor should be located AT LEAST 1/2” from any uninsulated conductor.2. Sensor features a flexible iris which allows the sensor to hang on the conductor if local codes permit. A bracket is included for screw mounting or attaching to DIN rail. For screw mounting, drill two 3/32” pilot holes using the bracket as a template; ensure no drill shavings are present in enclosure. Attach bracket with screws provided.3. Clamp sensor around INSULATED CONDUCTOR ONLY, 600VAC MAX to be monitored.4. Snap the sensor into the mounting bracket.5. Wire the output of the sensor to a control panel digital input loop not to exceed 30VAC/DC wetting voltage.

The sensor scale is pre-calibrated for motors operating at a minimum of 75% FLA. On startup, the sensor output will close when monitored current exceeds 70% FLA, and open if current is below 60% FLA to indicate load loss (broken belt, coupling shear, etc.) For lightly loaded (oversized) motors operating below 75% FLA, the sensor should be set to a proportionally lower FLA to ensure positive status detection and avoid nuisance alarms.Smaller (less than 5HP) motors and/or lightly loaded motors may not have sufficient reduction in amperage (below 60% FLA) for the sensor to detect belt loss immediately. The sensor will detect the belt loss when the motor is restarted, as long as the unloaded motor current is below 70% FLA.For improved performance on small and lightly loaded motors, consider the following options: 1. Use model C-2330 self-calibrating, microcontroller based sensor. 2. Perform conventional calibration.Conventional Calibration (High Accuracy)Follow all safety precautions outlined in this manual. Follow ALL requirements in NFPA 70E for safe work practices and for Personal Protective Equipment (USA) and other applicable local codes when installing this product. Read all warnings carefully.1. Adjust knob on sensor to maximum FLA. (Fully clockwise)2. With motor operating normally, adjust knob SLOWLY counter-clockwise until Hi LED is lit.3. Adjust knob a few degrees more to prevent nuisance alarms.100%85%75%70%Motor FLANormal Run Range(Closed above this level)Sensor Threshold(Open below this level)60%}OFFNormal Alarm Range55%35%BELT LOSS40%5-20HP20-100HP>>1-5HP}100%85%75%70%Motor FLANormal Run Range(Closed above this level)Sensor Threshold(Open below this level)60%}OFFNormal Alarm Range55%35%<- BELT LOSS40%5-20HP20-100HP>>1-5HP}Normal OperationSmall / Lightly Loaded Motor Operation1.
