Split-Core, Adjustable Current Switch
with 120VAC/DC Output
quick install
1. Plan the installation:
Locate a mounting surface for the removable mounting bracket that will allow the
monitored conductor to pass through the iris, or "window" when it is installed. Determine
cable routing for the controller connection, allowing wiring to reach the mounting location.
2. Install mounting bracket
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. Close up and power up!

The H609 is a current-sensitive switching device which monitors current (amperage)
in the conductor passing through it. A change in amperage in the monitored
conductor which crosses the switch (setpoint) threshold plus the hysteresis value will
cause the resistance of the 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.
operation
notes
troubleshooting
calibration
For load currents less than sensor minimum rating:
Wrap the monitored conductor through the center hole and around the sensor body
to produce multiple turns through the "window." This increases the current measured
by the transducer.
• Controller must be
programmed to account
for the extra turns. e.g., if
four turns pass through
the sensor (as shown) the
normal controller reading
must be divided by 4.

For load currents greater than sensor maximum rating:
Use a 5 Amp (H681x series) Current Transformer (CT) as shown.
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.
Establish normal load conditions.

Turn setpoint screw clockwise until Status OPEN LED turns ON.
S-l-o-w-l-y turn the screw counter-clockwise until the Status CLOSED LED just turns ON.
Turn the screw an
additional ¼ turn
counter-clockwise for
operational margin.
B. To monitor over-current (mechanical problems, seized impeller)

1.Turn setpoint screw counter-clockwise
until Status CLOSED LED turns ON.
2.S-l-o-w-l-y turn the setpoint screw clockwise
until the Status OPEN LED just turns ON.
