Follow safe electrical work practices. See NFPA 70E in the USA, or applicable local codes.
This equipment must only be installed and serviced by qualified electrical personnel.
Read, understand and follow the instructions before installing this product.
Turn off all power supplying equipment before working on or inside the equipment.
Use a properly rated voltage sensing device to confirm power is off.
DO NOT DEPEND ON THIS PRODUCT FOR VOLTAGE INDICATION
• Only install this product on insulated conductors.
Failure to follow these instructions will result in death or serious injury.
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 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.

OPERATION
CALIBRATION
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.
Establish normal load conditions.
NOTES

First Time Power Up: No calibration needed, unit will automatically learn normal
load when powered.

To manually learn
normal load:

STOP
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.

CAUTION
RISK OF EQUIPMENT DAMAGE
• Derate the product’s maximum current for the number of turns
through the sensing window using the following formula.
Note: Status contacts may close momentarily when unit is initially recovering from an extended
(typically longer than 10 seconds) power OFF state to an ALARM state.

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

Solution
• 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
