Notably, the ECMCS switches operate independently of external power sources, as they derive power from the conductor under surveillance. Featuring an adjustable trip level, ACI's ECMCS switch enables users to set the desired threshold for accurate motor status indication across a wide range of ECM applications. To facilitate installation, ACI offers a calibration tool, providing visual feedback to assist installers in configuring the output switch.
Installation of the ECM current switch is straightforward, with the option to secure it to the monitored cable using a cable tie and the integrated cable tie anchor feature of the housing. Additionally, the ECMCS switch includes an attachable mounting foot, facilitating versatile mounting options—either via a single Tek screw or by snapping it directly onto a 35mm DIN rail.
Applications: Pump Status, Fan Status, Compressors, Air Handlers, Residential Furnaces, Motor Status - The ECM Switch is not intended to monitor status in VFD motors
Lowest Trip Point Available
The ECM Current Switch was designed from scratch for unprecedented performance and protection. With the lowest adjustable trip point in the industry, ACI's ECM Current Switch can be set above the standby current and below the lowest operating current, preventing false alarms.
ECM (Electronically Commutated Motors) are becoming increasingly popular in HVAC applications due to their greater efficiency, quieter operation, and potential tax incentives in certain states.
This ECMCS Current Switch offers a variety of features, including new core technology, eliminated LED to reduce power consumption, the lowest trip point in the industry at 0.075 Amps, fewer wire wraps, and a trip adjust tool.
Trip Adjust Tool
If the ECM current switch status indication does not correctly indicate motor status, use the following steps to perform the calibration of the status indication. For switch status indication, ACI recommends the ECM Trip Adjust Tool be installed on the switch terminal block. The Trip Adjust Tool will give LED indication of a closed switch.
If the Trip Adjust Tool is unavailable, direct connection to the BMS(Building Management System) is recommended. Note that the BMS usually has a slight delay in response time. Response time must be taken into consideration when calibrating.
