Sometimes, in the process of using conlog prepaid meters, certain errors are thrown up, which may leave non-technical customers confused, and resorting to irrelevant steps in resolving the errors.
Hence, it becomes essential for prepaid meter users to learn the errors and their meaning so as to provide solutions that can work. Note that errors can be due to Token, Connectivity, or Configuration from the meter itself.
If the prepaid meter is new, it must first be activated before tokens can be loaded, After activation, the Key Change Token is also needed to configure it, then it can accept credit tokens.
The following conlog meter errors are worth knowing:
This error means “Terminal cover open”. It is displayed when the terminal cover is not fitted correctly, which may be due to the incorrect installation of the terminal cover during meter commissioning, or when entering a clear tamper token.
If it is from meter commissioning, install terminal cover and repeat the commissioning procedure, otherwise, install the tamper cover correctly and re-enter the clear tamper token
This error means “Invalid token”. It is due to failed authentication of a token.
The token could be invalid because the meter serial number on the token doesn’t match the physical meter number on the meter or the tariff index on the token is not the same as the tariff index programmed into the meter.
It can also be due to the supply group code that the token was made on differing to the supply group code in the meter, but most times, it is because the token was entered into the meter incorrectly.
To resolve the error, check the printout of the token. Try the short code #000# to compare the parameters of the meter, or run a specific item in the test.
You can also Run #030# for the supply group code (SGC), and #006# for the tariff index. All the information should be validated to determine why the token didn’t work.
This error means “Token entry lockout active”. It happens when a token is entered incorrectly or is not valid, and the meter automatically locks out for a period of time.
Wait till the remaining lockout time is elapsed. Once this time is complete, enter a valid token.
