ERMS Minimum System Requirements

Minimum System Requirements

Device	Software/Firmware Revision
MicroLogic X control unit Firmware	2.000.003
EcoStruxure Power Commission PC app	2.12

ERMS Test Necessary Tools

The following is needed to perform a tripping test:

EcoStruxure Power Commission Software
Mini B USB Cable

NOTE: EcoStruxure Power Commission Software can be downloaded from the Schneider Electric website (SE.com).

ERMS Engagement / Disengagement

MasterPacT™ MTZ circuit breakers provide two means of engaging the ERMS function when used with the ERMS digital module (LV850009):

Use of the EcoStruxure Power Device App for Android and iOS.
Use of a physical switch

The EcoStruxure Power Device application allows user to engage/disengage the ERMS function via Bluetooth wireless communication using Android or iOS compatible devices.

Android™ devices can also engage/disengage ERMS through a direct connection to the control unit's USB port using a USB OTG (On The Go) cable.

NOTE: If no ERMS switch is present, USB OTG cable can be used to engage ERMS for MicroLogic Xi.

The physical switch option allows the user to engage/disengage the circuit breaker’s ERMS function.

NOTE: The EcoStruxure Power Device App can be downloaded from the Google Play™ store for Android and from the App Store™ for iOS devices.

Energy Reduction Maintenance Setting (ERMS) Trip Test

1	Connect the PC to the MicroLogic control unit using a USB cable.
2	On the PC, open the EcoStruxure Power Commission software and click “Connect to device directly” (A). This will allow the user to access the MasterPacT MTZ circuit breaker through the software.
3	The protection settings are available under the configure option in device view: Click on “CONNECT TO DEVICE” (B) to connect through direct USB connection.
4	If it is not necessary to view/change the protection settings, skip to step 5 below. To view/change the protection setting: Click on the “Configure” option (C). Click on the “Protection” tab (D). Click “WRITE TO PROJECT” (E ) to transfer the Device Values to the project. This will transfer the device values in all the tabs to the project so the project and device values are the same. Change the settings if required for the application and click on “WRITE TO DEVICE” (F) to transfer the modified project values from all the tabs to the device. Recheck the settings and click on “PROCEED” (G) . Enter the password and click on continue (H) to perform the operation. NOTE: The default password is 0000.
5	Engage the ERMS. The control unit screen should turn blue and the ERMS LED is blue when the ERMS is in engaged state. Refer to MasterPacT MTZ Energy Reduction Maintenance Settings (ERMS) User Guide (0614IB1802) for steps to engage/disengage ERMS using the physical ERMS switch or the EcoStruxure Power Device smartphone app. NOTE: The ERMS setting cannot be changed when the ERMS is engaged.
6	Confirm that the device view page shows “ERMS ENGAGED” beside the circuit breaker name (I). Click on “Automatic trip tests” (J).
7	On The automatic trip Curve screen, select Pre-configured (K) or Custom test point (L). For Pre-configured Test point : Select ERMS and any other set of trip curve that needs to be tested (M). Select the Protection test from the list to be performed (N). Note: For ERMS trip curve it is mandatory to select instantaneous protection test.
8	Click on “RUN TEST” (O).
9	Read the NOTICE screen. If understood, click on “I UNDERSTAND” (P) to proceed.
10	Enter the password and click “CONTINUE” (Q) NOTE: The default password is “0000”.
11	On completion of the ERMS test, reset the control unit and close the circuit breaker to proceed to the next test.
12	To move to the next step, disengage the ERMS and confirm the ERMS is disengaged. Click on “CONFIRM”.
13	On completion of the selected trip tests, the test results for all selected trip curves are displayed on the bottom of the screen.
14	Click on the Reports tab and select Automatic trip test report to generate the test report.
