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 />

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 />
