3. Start operation command in direction OPEN. Measure operating time from
CLOSED to OPEN.
→
Wait until FQM end position switch trips or end position OPEN has
been reached.
→
Check actuator reaction:
3.1 Operation stopped when reaching end position switch OPEN?
➥
End position OPEN reached signal (output signal active), i.e.:
-
LSO 38-20=NC output (NC contact) = open
-
LSO 19-21=NO (NO contact) output = closed
➥
End position CLOSED not reached signal (output signal inactive), i.e.:
-
LSC 35-23=NC output (NC contact) = closed
-
LSC 22-24=NO (NO contact) output = open
➥
No fail safe fault signal may be issued (“FS ready” signal).
3.2 Did measured operating time from end position CLOSED to end position
OPEN match the SQ actuator settings?
4. Operate FQM via actuator into intermediate position.
→
Check FQM end position switch:
➥
End position OPEN not reached signal (output signal inactive), i.e.:
-
LSO 38-20=NC output (NC contact) = closed
-
LSO 19-21=NO (NO contact) output = open
➥
End position CLOSED not reached signal (output signal inactive), i.e.:
-
LSC 35-23=NC output (NC contact) = closed
-
LSC 22-24=NO (NO contact) output = open
➥
No fail safe fault signal may be issued (“FS ready” signal).
8.4.4. Test counter of FQM diagnostic operations within the AC .2 actuator controls
Configuration
When using the ESD safety function, this test must be done for each proof test test
once the ESD function has been tested.
Test procedure
A diagnostic operation (internal diagnostics of the FQM) is initiated while testing
whether the diagnostic operation counter is incremented by one.
Test sequence
1.
Note the value of parameter FQM count. diagn. op. (PRM_5263) in the Diagnost-
ic>FQM menu.
2. Start internal diagnostics of the FQM by operating the FQM from the end position
opposite the safety end position (i.e. fail safe CLOSE end position OPEN).
3.
Check in the Diagnostic>FQM menu, whether the value of the parameter FQM
count. diagn. op. (PRM_5263) has been incremented by one.
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.
