Flow chart

Acceptance test, repetitive function test and STO revalidation test:

Maintenance

The STO function shall be maintained by periodic testing. To perform the maintenance, do the following:

−

Repetitive function test.

−

Acceptance test.

Fault/Trip

If the drive was repaired and the changed hardware is not in the revalidation check list below, no test is needed.

After a fault/trip the STO function shall be tested depending on the type of repair.

If the complete drive module has been exchanged, do the following:

−

Repetitive function test.

−

Acceptance test.

If the drive was repaired and the changed hardware is in the revalidation check list below, do the following:

−

STO revalidation test.

−

Repetitive function test.

−
