✎Configuration
Fail safe position OPEN and CLOSED (safety position OPEN and CLOSED)
⎕ Yes
⎕ No
➥ 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 present (“FS ready” signal).
☒ ✓ = Executed
☒ Yes = Condition met
☒ No = Condition not met
If the answer to one of the questions is no, the safety instrumented system must be checked.
10.2.3. FQM diagnostic operation counter checklist
When using the ESD safety function, this test must be done for each proof test test
once the ESD function has been tested.
Table 13: Test sequence checklist
✎Test
Counter of FQM diagnostic operations within the AC .2 actuator controls.
⎕ ✓
1. Note the value of parameter FQM count. diagn. op. (PRM_5263) in the Diagnostic>FQM menu.
⎕ ✓2. Start internal diagnostics of the FQM by operating the FQM from the end position opposite the safety end position
(i.e. for fail safe CLOSE from end position OPEN).
⎕ Yes
⎕ No
3. Has the value of parameter FQM count. diagn. op. (PRM_5263) in the Diagnostic>FQM menu been incremented
by one?
☒ ✓ = Executed
☒ Yes = Condition met
☒ No = Condition not met
If the answer to one of the questions is no, the safety instrumented system must be checked.
