Product Overview

The H906 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 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 H906 requires a 5-30 VDC external power supply to generate its output.

The H906 housing oers unprecedented mounting exibility. The mounting bracket can be attached in three dierent places. Additionally, the bracket is compatible with the Veris AH01 DIN Rail clip, allowing DIN mounting.

Use DIN Rail Mounting clip (Veris part number AH01) to mount on standard DIN rail.

Disconnect and lock out power to the enclosure containing the conductor to be monitored.

1. 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 routing for the controller connection, allowing the wiring to reach the mounting location.

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 (solid-state contact) and to the external power supply. Observe polarity.

4. Snap the sensor over the conductor and clip the assembly to the mounting bracket.

5. Secure the enclosure and reconnect power.

6. Calibrate the sensor with the load running normally.

Notes

For load currents greater than sensor maximum rating:

Use a 5 Amp (H68xx series) current transformer (CT) as shown. This technique can be combined with wrapping (see below) to add range for a low current load on a high current source.

240A

>135 A (sensor max.)

DANGER: 5A CTs can present hazardous voltages. Install

300A:

H68 xx-5A CT

CTs in accordance with manufacturer's instructions. Terminate the CT secondary before applying current.

For load currents less than sensor minimum rating:

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).

< 2.5 A (Sensor Min.)

• 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.

Problem Solution

No Reading at Controller • Check sensor calibration (see above)

• Check for control voltage at sensor (5VDC<voltage<30V)

• Check for amperage in monitored conductor (> 2.5A)

• Verify correct polarity

• Assure that sensor core mating surfaces are clean and that the core clamp is completely closed
