INSTALLATION

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 1/2” from any uninsulated conductors.

Determine cable routing for the controller connection, allowing 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 between the sensor and the controller (solid-state contact).

4. Snap the sensor over the wire to be monitored and clip the assembly to the mounting bracket.

5. Calibrate the sensor (see page 2) with the load running normally.

6. Secure enclosure and reconnect power.

OPERATION

The H609 is a current-sensitive switching device that monitors current (amperage) in the conductor passing through it. A change in the conductor’s amperage that crosses the adjustable switch 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 120 volts. The H609 requires no external power supply to generate its output.

CALIBRATION

Before beginning calibration, establish normal load conditions.

Then choose either A or B below.

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.

DANGER: 5A CTs can present hazardous voltages.

Install CTs in accordance with manufacturer's instructions.

Terminate the CT secondary before applying current.

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.

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.

TROUBLESHOOTING

Problem Solution

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

• Check for control voltage at sensor (<120V)

• Check for amperage in monitored conductor (> 1.25A)

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

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.
