This device has four wiring options, detailed on page 2-3 of this installation guide. Choose the option appropriate to the application and follow instructions. operation The H540NS and H548NS devices combine a switching relay and a current status sensor into a single housing. The device is connected in series between the power source and the motor device, and the relay controls the on/off functioning of the motor. The current switch trip point is fixed at 0.25 A on the H540NS and adjustable from 0.5 to 15 A in the H548NS. The maximum load is 15 A for both devices. The H540NS and H548NS require no additional power source for operation. VERIS INDUSTRIES, IN C.

TM INSTALLATION GUIDE H540NS/548NS calibration (H548ns only) Note: Testing the solid-state status output of this sensor with a digital ohmmeter may yield inaccurate, but relative readings of switching (e.g. 6 MΩ) Use an analog V-O-M for readings similar to loop values. Calibration to be done while motor is running normally. 1. For under-current status indication: (Belt loss, fan & pump status) • Turn the set point screw clockwise until the status closed LED goes out and the status open LED comes on. • Turn the set point screw counter-clockwise until the status open LED goes out and the status closed LED comes on. • Turn the set point screw 1/2 turn counter-clockwise. • The sensor is now calibrated to provide indication of current flow below normal full load amps. Output Status: Normal: Output closed Alarm: Output open 2. For over-current status indication: (Locked rotor) • Turn the set point screw counter-clockwise until the status open LED goes out and the status closed LED comes on. • Turn the set point screw clockwise until the status closed LED goes out and the status open LED comes on. • Turn the set point screw clockwise 1/2 turn • The sensor is now calibrated to provide indication of current flows above normal full load amps Output Status: Normal: Output open Alarm: Output closed c.) surface mounting: Line Voltage Wires Connect line voltage wires to line current terminals Wire the 12 AWG lines from the controller through the side of the device, onto the line current terminals. Tighten line current terminal blocks to 12 in-lb (1.35 N-m) torque. d.) nipple mount to another enclosure: Insert the conduit nuts (provided) into the slots in the side hole of the device for additional weight support. Connect line voltage wires to line current terminals ENCLOSURE Nipple to existing enclosure (conduit nipple fitting not provided) Line voltage wires Wire the 12 AWG lines from the controller through the side of the device, from the enclosure to the line current terminals. Tighten line current terminal blocks to 12 in-lb (1.35 N-m) torque. 5. Use the knockout seal to cover any unused holes in the housing. Attach the cover, securing with the screws provided. NOTE: If a conduit is used, connect the conduit to the mounting hub before connecting it to the device. Be sure to support the H540NS/548NS housing when nipple‑mounted to another enclosure, or the unit may shift on opening, potentially causing undue stress on the wiring and the terminals.Z202763-0D PAGE 4 ©2012 Veris Industries USA 800.354.8556 or +1.503.598.4564 / support@veris.com 07122 Alta Labs, Enercept, Enspector, Hawkeye, Trustat, Veris, and the Veris ‘V’ logo are trademarks or registered trademarks of Veris Industries, L.L.C. in the USA and/or other countries.

Current Sensor: In-series current sensor for motor status. 3. Relay: Enables actuation of circuit by a control system. 4. Relay Coil Terminal Blocks: Wire the output signal from the control panel to actuate the relay. 24 VAC/DC; 36 mA nominal. 5. Status Terminal Blocks: Wire the status input back to the control panel. 6. Relay Status LED: For positive indication of energized coil. 7. Status Open LED: Indicates that the current is below the trip point and the status contact is open (used to calibrate the current switch in H548NS models only). 8. Current Switch Set-Point Screw: Used to adjust the point in the current range at which the current switch will change states (used to calibrate the current switch in H548NS models only). 9. Status Closed LED: Indicates that the current is above the trip point and the status contact is closed (used to calibrate the current switch in H548NS models only). CAUTION! Do not rely on status indicators to determine whether or not the relay contacts are connected to a power source. Doing so may result in injury or death from electrical shock. If the connections to the unit are made through more than one metallic conduit, bond the conduits to prevent the hazard of electric shock. A bonding plate is available (Veris part AH10).Next >
