INSTALLATION GUIDE
H606
OPERATION
The H606 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 5 to 30 volts. The H606 requires 5 to 30 VDC external power supply to
generate its output.
TROUBLESHOOTING
Problem Solution
No Reading at Controller • Check sensor calibration (see above)
• Check for control voltage/current at sensor (<30V, <0.2A)
• Check for amperage in monitored conductor (> 1.25A)
• Check that at least 5 VDC are across the contacts.
• 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.

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.

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.
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.
