SFT2841 Version for older Sepam 20 Series

[Ahalliwell]

Hello, I have an old Sepam 20 (from around 2013) is the latest version of SFT2841 V17.4 fully compatible with this relay?

I can connect to a spare relay on the bench but am unable to change any of the protection settings even after entering the device passwords.

I press apply then navigate away from the protection settings page, then when I go back the settings it is the same as the default value.

I have enabled the "Remote Settings"

If I also try to upload a set of settings I get an error saying that the "H2 restraint is not supported by the Sepam" the Sepam software is VO621

Hello @Ahalliwell

Thank you for your question regarding the compatibility of SFT2841 V17.4 with your Sepam 20 Series relay.

Given the specific issues you're experiencing — such as settings not applying correctly and upload errors — I recommend contacting your official support channel.
They’ll be able to assist you based on the exact firmware version and configuration of your relay, and escalate the case to the appropriate team if needed.

Hi @Ahalliwell,

We apologise for the delay.
It appears that our response from last month did not reach you.

In theory, the new version of the SFT2841 software is compatible with an older version of the Sepam software. However, Sepam's overall capabilities are limited to the functionalities associated with the current revision of the Sepam unit. This means that a configuration file generated using SFT2841 offline (i.e. not connected to Sepam) may be rejected by Sepam when downloaded if it includes new functionalities that are not supported by the current version of Sepam.

Unfortunately, we do not have the relevant hardware to validate your observation.

Therefore, we propose upgrading the firmware version of the relay to the latest one, which is compatible with any hardware base.

We will send you the procedure via the relevant communication channel.

Regards,
