INSTALLATION

NOTICE

• This product is not intended for life or safety applications.

• Do not install this product in hazardous or classiﬁed locations.

• The installer is responsible for conformance to all applicable codes.

• Mount this product inside a suitable ﬁre and electrical enclosure.

Load

DDC CONTROLLER

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 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 contac t).

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

5. Secure enclosure and reconnect power.

H10F

INSTALLATION GUIDE

OPERATION

The H10F is a over-current and under-current monitor intended for use with a PLC or other system controller. The current switch learns the nominal amperage on the line, then monitors for amperage changes greater than ±20% of the learned value. If the amperage goes out of the normal range, the current switch changes output state, raising an alarm in the system controller. This alarm state persists until the amperage comes back to within ±15% of the learned value for 30 seconds to ensure that the system has truly returned to normal operation. The status output is suitable for connection to system controllers or other data acquisition equipment operating at up to 1A and 30VDC. The H10F requires no external power supply to generate its output.

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.

First Time Power Up: No calibration needed, unit will automatically learn normal

load when powered.

To manually learn norm al load:

GREEN

STOP

When only the GREEN LED blinks, the unit is measuring normal current.

To reset automatic learn mode (normal load conditions):

GREEN

Turn oﬀ power while lights are still blinking!

At next power-up, unit will automatically learn normal load.

OPE RATIN G STATES

H68 xx-5A CT

DANGER: 5A CTs can present hazardous voltages. Install CTs in accordance with manufacturer's instructions. Terminate the CT secondary before applying current.

CAUTION

• 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 through the window. This increases the current measured by the switch.

Program controller to account for the extra turns. e.g., if four turns pass through the sensor (as shown), then divide the normal controller reading by 4.

TROUBLESHOOTING

Problem Solution

No Reading at Controller

• Check sensor calibration (see above)

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

• Check for amperage in monitored conductor (> 3.5A)

• Assure that sensor core mating surfaces are clean and that

the core clamp is completely closed
