CMI Software

The Control & Monitoring Interface (CMI) software is used to interact with the IMCC Smart Motor Mechanism for disconnect switches. It provides advanced configuration, monitoring, and analysis features, in addition to general functions such as operations download, installation wizard, settings & drivers management and firmware update.

Setup Wizard

The CMI Software comes with a robust setup wizard for setting up the IMCC motor mechanism. It covers all the steps to get the disconnect switch up and running with the IMCC motor operator in a record time. The wizard assists the installer with the following configuration tasks:

  • Device Identification
  • Preparatory Steps
  • Configuration File Loading When Available
  • Opening and Closing Position Setup
  • Positioning Validation
  • Motor Wiring Validation
  • Alarm Operating Speed Setup
  • Maximum Speed Setup
  • Reference curve and Tolerance Limits Setup
  • Output Signals Setting

Real-time monitoring

The monitoring window provides real-time information of the motor mechanism and the disconnect switch status. It is very useful for installation, configuration, diagnostic and training & demonstration. The following information is available as seen in the corresponding image on the right.

  • Current & voltage
  • Alarm status
  • Operating modes
  • Error status and description
  • Position
  • Heater Status
  • Speed
  • Environmental variables

The configuration window brings together all the controls related to the configuration of the IMCC Motor Mechanism. This panel contains four main sections among which the General Settings section containing the failure, failure action, heater management and current limit settings. The following subsection provide a description of the other three sections.

Operation Settings

The operation setting panel is used to configure the open and close operation. A gradual slope is calculated between each point to build a very smooth and gradual current curve. These points of adjustment are used to make soft start at the beginning of an operation, gradual deceleration at the end and for removing bouncing or knocking (or both) within the operation cycle or within the jaws area. On high voltage switches with very long blades, the operations can be improved significantly in a very impressive fashion. The various parameters that can be configured are described below.

  • Position and Speed
  • Maximum, Alarm and ICE breaking operating speeds
  • Delay before operation
  • Operation Time Out
  • Reverse Motor Direection

Tolerance Areas Settings

One important aspect of the monitoring of the disconnect switch relies on a reference motor current curve surrounded by two tolerance limits. This concept provides the ability to detect switch failures such as blockages, breakages and misalignments. The curve is generated automatically at the time of configuration and the tolerance limits are primarily build using offset parameters and fine tuned by modifying the curve directly on the graphic using the mouse. This way provides a very fast and flexible way for creating efficient and reliable reference curves and tolerance limits.

  • Reference curve automatic generation
  • Tolerance limit offsets
  • Direct Editing on the graphics

Signaling Settings

The CMI Software provides a very easy to use and flexible way for configuring the relay output signals. Each output is physically identified by a number that correspond to the Output Signal Number in the software. Each signal can be configured by first selecting the signal number and then selecting the right functions. The available signals are the following:

  • Contact “a” – Closing Signal
  • Contact “b” – Opening Signal
  • Local
  • Remote
  • Manual
  • Alarm 1
  • Alarm 2

The alarm 1 and 2 are alarm signals generated by the IMCC motor operator upon detection of a technical problem. Minor issues that do not prevent the disconnect switch from working, such as a temperature reading issue is classified as an Alarm 1. Critical failures that stop the disconnect switch from functioning are classified as an Alarm 2.

CMI Signaling Configuration


The IMCC Motor Mechanism records up to 400 operations in local permanent memory. These operations are available for download using the CMI Software and can be displayed in the Analysis panel. Various analysis can be performed, as an example, one can display many operations over a certain period of time and perform trend analysis. All parameters are available as a function of time and position, which provides the possibility of detecting potential wear or lack of lubrication in certain area of the curve where the current raises over time.

  • Up to 400 operations recorded
  • Current, voltage & torque available function of time and position
  • Multiple curves displayed on one graphic
  • Parameters available as a function of time and position
