Disconnect and lock out power to the conductor to be monitored.1.

Choose a location for the sensor. The monitored conductor must pass through the 2.

iris, and the sensor must be at least ½” from any uninsulated conductors.

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.

INSTALLATION GUIDE

opEration

The H970HCA is a current-sensitive device that monitors DC current (amperage) in the conductor passing through it. The unit combines a Hall Eﬀect sensor with proven transducer circuitry, with a status output suitable for connection to building controllers or other appropriate data acquisition equipment operating at up to 30 volts. The H970HCA requires supply voltage to generate its output. Selectable amperage ranges and output types maximize the installation ﬂexibility.

The H970HCA housing oﬀers unprecedented mounting ﬂexibility. The mounting bracket can be attached in three diﬀerent places. Additionally, the bracket is compatible with the Veris AH01 DIN Rail clip, allowing DIN mounting.

notEs

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.

Problem Solution

The LED is oﬀ and no signal is

produced

The LED is on solid and the output

is at maximum

Verify that power is applied to PWR (+) and GND (-)

terminals

Verify that the amperage range selection switch is

in the proper position for the current applied to the conductor.
