Unable to Recharge the prepaid meter

Solution: Connectivity Check: Confirm the meter is successfully communicating with the server. Serial Number Verification (SmartComm): Access the SmartComm Customer Master and ensure the serial number recorded matches the physical serial number of the connected meter. Duplicate Configuration Check: Verify that no two meters are incorrectly configured with the exact same serial number in the system.

Email Configuration SMTP Details Outlook

Solution: SMTP Host/Server Name: For Outlook.com: smtp-mail.outlook.com For Office 365/Microsoft 365: smtp.office365.com SMTP Port:587 (recommended) Encryption Method: STARTTLS Authentication: Your email account needs to be authenticated, so enable login or use the ""My outgoing server (SMTP) requires authentication"" option in your email client. Username: Your full Outlook email address (e.g., yourname@outlook.com or yourname@domain.com) Password: Blank

Email Configuration App Password creation for Gmail account

Reason - Gmail will work only with a secure encrypted app password Solution: Go to your Google Account settings. Navigate to the Security tab. If you don't have it enabled, turn on Two-Step Verification. Find and click on App passwords. Select an app name (like ""SMTP"" or ""Mail Client"") and click Generate. Copy the generated 16-character password and use it in your mail client's password field instead of your main Gmail password.

Email Configuration SMTP Details Gmail

Solution: Gmail SMTP Settings SMTP Server: smtp.gmail.com Port: 587: (requires STARTTLS/TLS) 465: (requires SSL) Authentication: Required Username: Your full Gmail address (e.g., user@gmail.com) Password: An App Password generated from your Google Account security settings Security/Connection: TLS or SSL, depending on the port chosen

Transfer existing sensor to a different gateway

Reason - Loss of old data stored under device id created Solution: To prevent data loss, edit the sensor and use the "Move to Gateway" option to transfer the sensor to a different gateway.

Asset list is not available in the filter

Reason - The asset is not assigned to the organization Solution: Check the asset selection settings in organization settings

Reason - Sensor/gateway limit exceeded Solution: Check license information for sensor/gateway limit

Cannot change the ip address of gateway

Reason - The ip address should is not available Solution: 1. if company network is being used check the accesibility to access 2. check if set ip is with in subnet range 3. Check if Primary and Secondary DNS is correct as per network settings 4. Set the Default Gateway IP to match the router's IP or the company network's default gateway IP.

3rd part meter not communication

Reason - 1. Memory map configuration wrong 2. (10 power -4 )Conversion factor is not available in third party memory map configuration 3. Data on modscan and software is matching but not matching with meter display readings Solution: 1. Verify data via Modscan, check wiring, confirm the meter parameter's datatype/function code in the memory map, and ensure the gateway supports that parameter datatype. 2. Can be added from conversion factor available in Master settings

Could not download certificate

Reason - All mandatory fields are not saved in organisation info settings Solution: All details should be given in mandatory field of organisation settings

Industries require energy management to control the spiralling costs on electricity bills. Small scale industries may have apprehensions on ROI if they go for a full-fledged Energy Management systems.

To use the continual improvement framework of PDCA (Plan - Do - Check - Act) for energy management, monitoring of existing energy usage is a must. As a first step towards this systematic approach, users can install L&T E&A’s 5000/6000 series Digital panel meter that comes with an inbuilt 8MB datalogger facility at their Incomer panel to start with. Based on the data analysis at Incomer level, they can plan to act on the energy guzzlers. For a comprehensive energy management system, they must use L&T E&A’s SmartComm EMS with ready to use analytics and reporting tools that will boost their energy conservation initiative.

What is the storage capacity?

8 MB of file storage can be translated as 29 parameters stored at 15 minutes interval daily is equivalent to approx. 2 years of time period. Below table shows data storage interpretation for number of days storage.

Parameters	Data Log Interval
	15 Min	30 Min	45 Min	60 Min
	No. of Days
1	10230	20460	30690	40920
2	6820	13640	20460	27280

How to enable this?

Smartlog is a free software utility tool to configure and download the data in an excel sheet.

Meter Type	Software Utility Type	Connection Type
5000 MFM series with RS 485 port	SmartLog - Com	Meter → Shielded twisted pair cable → RS485 to Ethernet convertor → CAT 6 cable → Laptop/PC. OR
6000 Max Demand Controller series with RS 485 port	SmartLog - Ethernet	Meter → Shielded twisted pair cable → RS485 to USB convertor → Laptop/PC
5000 MFM series with Ethernet port		Meter → CAT 6 cable → Laptop/PC

Meter Type	Software Utility Type	Connection Type
5000 MFM series with RS 485 port	SmartLog - Com	Meter → Shielded twisted pair cable → RS485 to Ethernet convertor → CAT 6 cable → Laptop/PC. OR
6000 Max Demand Controller series with RS 485 port	SmartLog - Ethernet	Meter → Shielded twisted pair cable → RS485 to USB convertor → Laptop/PC
5000 MFM series with Ethernet port		Meter → CAT 6 cable → Laptop/PC

Step 1: Install the software and configure the laptop for communication settings as per the convertor and utility used. Press save button to enable the other two tabs

Step 2: Go to Datalog settings for configuration of below aspects

Slave id: Select the correct slave id of the meter

Time interval: Select from options of 1m, 5m, 10m, 15m, 30m,1h, 2h, 5h, 8h, 12 h.

Total parameters: Select from options of 1,2,4,9,14,29

Parameter list: Select maximum of 29 parameters from a list of 295 parameters that includes Energy, Power, Voltage, Current, THD, Individual Harmonics, Demand, K factor, etc.

Press Read button to read the meter, select the total parameters required say 4 nos. Select parameters one by one and press add button. The parameters will get populated on the right-side Added parameters area. Configure all these by pressing ‘Write’ button. Post this action, data will log in the meter.

Step 3: To download this data, complete step 1 and then go to Download tab.

Select the slave id and start Download button.

Output will be in an .csv format (excel sheet) as shown below:

Applications

Few applications are listed below though not exhaustive:

Monitor voltage variations at say 1 or 5 minute interval at incomer level to understand the voltage fluctuations from transformers.
Monitor energy consumption at 15 minutes interval.
Monitor running demand at every 15 minutes. Based on this data, the customer can analyse the existing contract demand levels. If the contract demand levels can be reduced by 5-10% then customer can save tremendously over a long term.
Log max demand at every 15 or 30 min interval to analyse demand trend patterns.
5000 series meters with analog inputs like temperature can be logged inside the meter and analysed for further actionable.
Monitor PF levels at every 1 hour interval.
Monitor K factor levels at Incomer level. (refer Watt File 4 for more details on K factor)

The next level approach will be to get a comprehensive report, trend analysis, email reports and analytics using SmartComm EMS.
