Locate a mounting surface for the removable mounting bracket that will allow the monitored conductor to pass through the iris, or “window” when it is installed and keep the product at least 1/2” (13mm) from any uninsulated conductors (CE). Determine cable routing for the controller connection, allowing wiring to reach the mounting location. Install mounting bracket 3. Drill holes to mount the bracket to the chosen surface using the included screws. Wire the output connections between the sensor and the controller.4.

A change in amperage in the monitored conductor that crosses the switch (setpoint) threshold plus the hysteresis value will cause the resistance of the status output to change state, similar to the action of a mechanical switch. This status information can be fed back to a building controller that interprets the signal and separately switches the relay. The status output can also be used to switch the relay directly. In this model, the setpoint is adjustable through the action of a twenty (20) turn potentiometer (see the CALIBRATION section). The status output is suitable for connection to building controllers or other appropriate data acquisition equipment operating at up to 30 volts. The H958 relay requires a 12VDC external power supply for operation. The H958 housing offers unprecedented mounting flexibility. The mounting bracket can be attached in three different places. Additionally, the bracket is compatible with the Veris AH01 DIN Rail clip, allowing DIN mounting. notEs troublEshooting For load currents less than sensor minimum rating: Wrap the monitored conductor through the center hole and around the sensor body to produce multiple turns through the "window." This increases the current measured by the transducer. 4x 1A DANGER: 5A CTs can present hazardous voltages. Install CTs in accordance with manufacturer's instructions. Terminate the CT secondary before applying current. H68xx-5A CT > 135A (Sensor max.) For load currents greater than sensor maximum rating: Use a 5 Amp (H68xx series) Current Transformer (CT) as shown. ProblemSolution No Reading at Controller• Check sensor calibration (see above) • Check for control voltage at sensor (<30V) • Check for amperage in monitored conductor (>2.5A) • Assure that sensor core mating surfaces are clean and that the core clamp is completely closed Setpoint screw has no stopsThe setpoint screw has a slip-clutch at both ends of its travel to avoid damage. Twenty turns CCW will reset the sensor to be most sensitive. Repeat calibration above. Both LEDs are litSetpoint screw is too far clockwise. See solution above.
