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 device at least 1/2” from any uninsulated conductors.
Determine cable routing for the controller connection, allowing wiring to reach
the mounting location.

INSTALLATION GUIDE

opEration

The H806 is a current-sensitive switching device that monitors current (amperage) in
the conductor passing through it. A change in amperage in the monitored conducter
that crosses the switch threshold will cause the resistance of the status output to
change state, similar to the action of a mechanical switch. The setpoint is adjustable
through the action of a 20-turn potentiometer (see 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 H806 requires 5-30 VDC
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.

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.

Both LEDs are lit Unit is out of calibration. Turn screw 20 turns CCW and recalibrate.

• Check sensor calibration (see above)

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

• Check for amperage in monitored conductor (>0.75A)

• Verify correct polarity

• 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.
