AUMA SA Series - Maintenance

2. Execute Safe STOP command in direction of the configured Safe ESD safety
function:
→
For "Safe CLOSING" (Safe ESD in direction CLOSE) configuration:
Set Safe STOP CLOSE input signal to 0 V (low).
→
For "Safe OPENING" (Safe ESD in direction OPEN) configuration: Set
Safe STOP OPEN input signal to 0 V (low).
3. Initiate safety operation:
Set Safe ESDa and Safe ESDb input signals to 0 V (low).
➥
Safety function is correct, if the actuator performs a safety operation into the
configured direction.
➥
No SIL fault signal may be issued.
4.
Set Safe ESDa, Safe ESDb, Safe STOP OPEN and Safe STOP
CLOSE input signals to +24 V DC (high) once the test is complete.
Information In addition to this test, all other proof tests described in this manual have to be per-
formed for the combination of Safe ESD and Safe STOP.
8.5. Maintenance
Maintenance and service tasks may only be performed by authorised personnel who
have been trained on functional safety (refer to chapter 5).
Once maintenance and service tasks have been finished, the functional test must
be completed by a validating process of the safety function including at least the
tests described in the <Safety equipment: check> and <Proof test (verification of
safe actuator function)> chapters.
In case a fault is detected during maintenance, this must be reported to AUMA Riester
GmbH & Co. KG.
