VERIS INDUSTRIES INSTALLATION GUIDE H608 opEration calibration The H608 is a current-sensitive switching device that monitors current (amperage) in Before beginning calibration, establish normal load conditions. the conductor passing through it. A change in amperage in the monitored conductor OK! that crosses the switch (setpoint) threshold plus the hysteresis value will cause A 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 Then choose either A or B below. twenty (20) turn potentiometer (see the CALIBRATION section). The status output is A. To monitor under-current (belt loss, coupling shear, status) suitable for connection to building controllers or other appropriate data acquisition equipment operating at up to 30 volts.

Controller must be 4x No Reading at Controller • Check sensor calibration (see above) programmed to account for the 0.5A • Check for control voltage at sensor (<30V, <1A) extra turns. e.g., if four turns • Check for amperage in monitored conductor (> 0.5A) pass through the sensor (as • Assure that sensor core mating surfaces are clean and shown) the normal controller that the core clamp is completely closed reading must be divided by 4. Setpoint screw has no stops 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. Both LEDs are lit Setpoint screw is too far clockwise. See solution above.
