Compatibility of Sepam version/SFT2841 version<br />
The About SFT2841 screen indicates the minimum version of SFT2841 that is<br />
compatible with the Sepam being used.<br />

up the SFT2841 compatible version screen.<br />
Check that the SFT2841 software version used is higher than or the same as that<br />
indicated on the Sepam screen.<br />
If the SFT2841 software version is lower than the minimum version compatible with<br />
the Sepam being used, the SFT2841 software cannot be connected to Sepam and<br />
the SFT2841 software displays the following error message: SFT2841 software<br />
version incompatible with the connected device.<br />
Preventive maintenance<br />
General<br />
The logic inputs and outputs and the analog inputs are the parts of Sepam least<br />
covered by the self-tests. (See “List of self-tests which place Sepam in the fail-safe<br />
position” page 4/17).<br />
They should be tested during a maintenance operation.<br />
The recommended interval between preventive maintenance operations is 5 years.<br />
Maintenance tests<br />
To perform maintenance on Sepam, see section “Commissioning: principles and<br />
method” page 7/21. Carry out all the recommended commissioning tests according<br />
to the type of Sepam to be tested.<br />
First test all the logic inputs and outputs involved in tripping the circuit breaker.<br />
A test of the complete chain including the circuit breaker is also recommended.<br />
