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

Pump Protection against Dry Run with eMPR300D, eMPR300I & iMMR Relays

Aug 20, 2025

Technical Articles

1. Problem:

Dry running pumps experience rapid temperature rise, damage to seals, bearings, and impeller, leading to permanent damage to pumps.

Traditional Solution:

Float switches or pressure sensors—often unreliable, difficult to maintain, and likely to fail frequently.

Solution:

With the help of eMPR & iMMR, Undercurrent protection function is able to detect the sudden, measurable drop in motor current or power consumption that occurs when the pump loses its water load (dry run).

Detailed Explanation:

Dry Run Condition and its effects:

Occurs when a pump runs without fluid (no load torque or back pressure).
The motor is under loaded, so current drops significantly below rated value.
Can cause over heating due to lack of cooling fluid, even though current is low.

Use of eMPR & iMMR for this problem:

High reliability since the relay constantly monitors the load current, regardless of liquid level or pressure switch state.

Detects a drop in load current or power using non-intrusive electrical measurements, then automatically trips the motor to prevent overheating and mechanical damage ensuring safety, reliability, and long equipment life.

In eMPR300D & eMPR300I we have settable pickup value range from 20% to 90% of Im and settable delay of 1 to 300 secs. In iMMR we have settable pickup value range of 15% to 100% of Im and settable delay of 0.100 to 600 secs.
By using eMPR & iMMR our motor is protected during Dry Run Condition.
