DocumentDocumentInstallation Guide Current Monitoring TM TM H608 Split-Core Current Switch, Adjustable Trip Point Product Overview DANGER The H608 is a current-sensitive switching device that monitors current (amperage) in the conductor passing through it. A change in amperage in the monitored conductor that crosses the switch (setpoint) threshold plus the hysteresis value causes the resistance of the FET status output to change state, similar to the action of a mechanical switch. In this model, the setpoint is adjustable through the action of a 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 H608 requires no external power supply to generate its output. HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH · Follow safe electrical work practices.

Locate a mounting surface for the removable mounting bracket that will allow the monitored conductor to pass through the center window when it is installed and that will keep the product at least ½" (13 mm) from any uninsulated conductors. Determine cable CONTACTOR Insulated Conductor ONLY DDC CONTROLLER routing for the controller connection, allowing the wiring to reach the mounting location. DI 2. Drill holes to mount the bracket to the chosen surface using the included screws. 3. Wire the output connections from the sensor to the controller (solidstate contact). 4. Snap the sensor over the conductor and clip the assembly to the Fan mounting bracket. Important: If there is a paper inhibitor sheet between the contacts, remove before use. 5. Secure the enclosure and reconnect power. Motor 6. Calibrate the sensor with the load running normally.

This technique can be combined with wrapping (see below) to add range for a low current load on a high current source. 240 A >175 A (sensor max.) 300A:5A H68xx-5A CT 4 A For load currents less than sensor minimum rating: DANGER: 5A CTs can present hazardous voltages. Install CTs in accordance with manufacturer's instructions. Terminate the CT secondary before applying current. Wrap the monitored conductor through the center window and around the sensor body to produce multiple turns. This increases the current measured by the transducer. Program the controller to account for the extra turns (e.g., if four turns pass through the sensor (as shown) divide the normal reading by 4). < 0.5 A (Sensor Min.) 0.35A 4x CAUTION RISK OF EQUIPMENT DAMAGE · Derate the product's maximum current for the number of turns through the sensing window using the following formula. Rated Max. Amps ÷ Number of Turns = Max. monitored Amps e.g. : 100A ÷ 4 Turns = 25 Amps max. in monitored conductor · Failure to follow these instructions can result in overheating and permanent equipment damage.

Then choose either A or B below. A. To monitor under-current (belt loss, coupling shear, status) Status 1. Turn setpoint screw clockwise CLOSED until Status Open LED turns on. Status OPEN Setpoint Status 2. Slowly turn the screw counter CLOSED clockwise until the Status Closed LED turns on. Status OPEN Setpoint 3. Turn the screw an additional ¼ turn counter clockwise for operational margin. ¼ Setpoint B. To monitor over-current (mechanical problems, seized impeller) Status 1. Turn setpoint screw counter CLOSED clockwise until Status Closed LED turns on. Status OPEN Setpoint Status 2. Slowly turn the setpoint screw CLOSED clockwise until the Status Open LED just turns on. Status OPEN Setpoint 3. Turn the setpoint screw an additional ¼ turn clockwise for operational margin. ¼ Setpoint Troubleshooting Problem No Reading at Controller Setpoint screw has no stops Both LEDs are lit Solution · Check sensor calibration (see above) · Check for control voltage at sensor (<30V, <1A) · Check for amperage in monitored conductor (> 0.5A) · Assure that sensor core mating surfaces are clean and that the core clamp is completely closed The 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. Setpoint screw is too far clockwise. See solution above.
