    1.1 Serial Port Option Serial port settings are under Setup>General>RS485 on HMI module. User should select same communication speed as set in eMCM. Because eMCM uses RS-485, user need to use RS-485 to RS232 converter for connecting to PC. Default serial port setting values of eMCM are shown below.

  • Page 30 This resets all setting to the factory defaults. Pressing this button shows following dialogue. After connecting current and voltage source to the eMCM and entering setting value (example: voltage 380V, current 3A), Calibrate inject same current / voltage value as setting value to the device and press [OK] button.
  • Page 31 Having configured eMCM for a particular motor, it can now be used for its intended purpose of monitoring and assessing the condition of the motor. In general, this involves first running eMCM to measure and learn the properties of the motor and then running eMCM in its test mode to perform the actual monitoring.
  • Page 32 • 7200V/100V, PT Ratio: 72 CT Ratio: The eMCM device has two models that support 3.5mA (eMCM 5A) and 100mA (eMCM 100A) current input. • For motors with nominal current of 10A and below, eMCM 5A device should be used together with current transformers with 3.5mA secondary current output.
  • Page 33 After completing initial setup, it is possible to proceed with the next step. In general, motor starts operation and eMCM starts acquisition current and voltage values. With these values, eMCM starts learning and improving. After these procedures are finished, eMCM starts motor status monitoring.

    Having configured eMCM for a particular motor, it can now be used for its intended purpose of monitoring and assessing the condition of the motor. In general, this involves first running eMCM to measure and learn the properties of the motor and then running eMCM in its test mode to perform the actual monitoring.
  • Page 40 3.2.2 Viewing alarm messages An alarm is indicated on AES Viewer, AES Configurator or MCM API Tool of eMCM by the message. Alarm followed by a text message. Please refer to the appendix for a complete list of possible alarm conditions and their remedies.
  • Page 41 3.3 Running CHECK MOTOR On first use of eMCM and each time any maintenance is performed on the motor, it is essential that the motor together with its connections are checked by running the CHECK MOTOR function. In this mode eMCM performs a short check on all motor connections to determine the phase ordering and that a motor is connected and running.
  • Page 42 The value of this dominant frequency must be entered from the Edit Settings menu. If eMCM measures the frequency to be out of the expected range, it will issue an alarm in both the CHECK MOTOR and LEARN modes and the user should adjust the frequency setting accordingly.
  • Page 43 Tool. Subsequent restart of eMCM can be achieved by selecting RESUME from the Status menu, which will cause eMCM to continue in its incomplete mode at the point of interruption. Thus, if it is necessary to stop eMCM for any reason, it can be restarted without affecting any existing data.
  • Page 44 Although eMCM should have met the majority of working conditions in the learning mode, it is still possible for it to fail to recognize a particular working point. In such a case, the user can elect to add the current operating point to the internal database using the UPDATE feature.
  • Page 45 Update iterations A value between 1000 - 2000 is recommended. eMCM does not update the flash with new values at each iteration, as this could shorten the flash lifetime. On the other hand, the longer data are stored in volatile memory, the greater the potential for data loss if Flash update rate power fails.
  • Page 46 Therefore, any fault of the equipment that affects the motor or the three-phase system is also observed by eMCM.
  • Page 47 Their change will allow eMCM to detect the isolation problem at an early stage. Though they are primarily used to detect electrical problems, they also can indicate mechanical problems as well. As an example, an imbalance or gear problem would cause dynamic eccentricity in the air gap.
  • Page 48 UPDATE mode. This will allow MCM to learn the new voltage supply conditions, after which the status will eventually return to normal.

    2. Appendix 2: Current and voltage sensor selection Voltage transformers, current transformer and current sensors must meet local standards and regulations. For North America, current and voltage transformers must be certified by an OSHA appointed NRTL to appropriate UL or CSA - product safety standards. When selecting a current sensor, both the maximum current the motor will handle in practice and the type of motor drive used should be considered.
