opEration

The H970LCB 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 H970LCB requires 15-30VAC/DC to generate its output. Selectable
amperage ranges and output types maximize the installation flexibility.

The H970LCB 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

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

terminals

The LED is on solid and the output

is at maximum

Verify that the amperage range selection switch is

in the proper position for the current applied to the

conductor.
