Product Overview

The H6ECM is a current-sensitive switching device that monitors current (amperage) in the conductor passing

through it. A change in amperage in the monitored conductor that crosses the switch threshold causes the

resistance of the FET status output to change state, similar to the action of a mechanical switch. The status output

is suitable for connection to building controllers or other appropriate data acquisition equipment operating at up to

30 volts. The product requires no external power supply to generate its output.

Electrically Commutated Motors (ECMs) are increasingly common as more energy conservation measures are

implemented. The ECM is a brushless DC motor that is supplied AC power, converts that power to DC current and

uses electronic switching to control the motor rotation. The ECM shaft speed can be reduced to save energy,

resulting in lower cost and less component wear. The H6ECM is optimized to provide meaningful proof of rotation

which veriﬁes that the ECM motor is operating as expected.

Installation Guide Current Monitoring ECM Series: H6ECM Operation Check TM 1. Issue a command to the ECM to rotate at normal operation speed and confirm that the motor shaft is rotating. 2. The status output of the H6ECM series product should be CLOSED (conductivity exists between terminals). 3. Issue a command to the ECM to stop rotation and confirm that the motor shaft is not rotating. 4. The status of the H6ECM series product should be OPEN (no conductivity exists between terminals).
