Configuration
Test procedure
7. Check Safe ESD reaction to "Forced torque seating in end position" (torque
after limit evaluation).
8. Check Safe ESD reaction for "no seating" (no evaluation of limit and torque).
9. Check Safe STOP function.
10. Check combination of Safe ESD and Safe STOP function.
11. Check safe end position feedback.
The safety-related signal input is appropriately assigned to check the safety-related
function. As a consequence, the actuator has to perform the safety function. For a
detailed description of the proof test steps, please refer to the following sections.
Intervals:
A proof test interval describes the time between two proof tests. Functionality must
be checked at appropriate intervals. The intervals are to be defined by the plant
operator. The probability of failure on demand (PFD) depends on the selected proof
test interval; in our example, it is valid for T
figures> chapter).
In any case, the safety-related functions must be checked after commissioning and
following any maintenance work or repair as well as at the T
the safety assessment.
If a fault occurs during proof test, safe function has to be ensured introducing
alternative actions. Please contact AUMA Riester GmbH & Co. KG.
The type of proof test to be performed depends on version and configuration of the
product. Only the tests applicable have to be performed.
If the safety function has been configured as ESD CLOSE/CLOSE + Safe STOP
OPEN/CLOSE or as ESD OPEN/OPEN + Safe STOP OPEN/CLOSE, all relevant
tests for Safe ESD and for Safe STOP (as well as the combination of Safe ESD
and Safe STOP) must be checked.
Before starting the test, we recommend reading the respective test procedure at
least once.
The actuator system has to be subjected following inspections first:
Visual inspection:
- Visual inspection for external damage and corrosion.
- Check electrical and mechanical connections.
Function check
Operate actuator at least once from CLOSED to OPEN and back (or vice versa).
- During this operation, monitor actuator for conspicuous noise and sluggish-
ness.
- Check whether both end positions are reached and signalled as expected.
The test is valid for all versions with Safe ESD function (irrespective of the "SIL
seating configuration"). The Safe ESD reaction to the different seating types is verified
in separate tests.
When switching the
Safe ESDa/Safe ESDb
into the configured direction must be triggered.
