AUMA FQM 05.1 - Check ESD Operation (Safe OPENING;CLOSING) with Additional Tripping in Case of

Test sequence
1. Operate actuator into end position OPEN (Safe ESD in direction CLOSE), or
into end position CLOSED (Safe ESD in direction OPEN).
Information:For the test, operation commands (in directions OPEN or CLOSE)
can be executed both from Remote (via DCS) and from Local at the controls
(via the push buttons of the local controls).
➥
No fail safe fault signal may be present (“FS ready” signal).
2. Initiate safety operation:
→
First set ESD input signal to 0 V (low).
→
When leaving the end position, start the operating time measurement.
➥
The FQM end position switch indicates the unseating from end position
by signal change.
➥
A fail safe fault signal (“FS fault” signal) must be issued.
→
Stop operating time monitoring when reaching the fail safe end position.
➥
The FQM end position switch indicates that end position has been reached
by signal change.
➥
The FQM operating time must comply with the indication on the name
plate for 90° swing angle or the specified time during commissioning.The
permissible operating time tolerance –50 %/+100 %.
→
Check whether valve is completely closed.
3.
Once the test is complete, set ESD input signal to +24 V DC (high) .
➥
FQM starts automatic initialisation (spring is wound).
➥
After successful initialisation, the “FS ready” signal is issued once initialisation
is complete. Initialisation time must be < 2 minutes.
8.4.2. Check ESD operation (Safe OPENING/CLOSING) with additional tripping in case of mains failure
Configuration
This test applies in addition for all versions with additional tripping in case of mains
failure of the safety function.
Test procedure
A further safety operation in direction of the configured fail safe position must be
triggered through the mains voltage.
Test sequence
1. Operate actuator into end position OPEN (Safe ESD in direction CLOSE), or
into end position CLOSED (Safe ESD in direction OPEN).
Information:For the test, operation commands (in directions OPEN or CLOSE)
can be executed both from Remote (via DCS) and from Local at the controls
(via the push buttons of the local controls).
➥
No fail safe fault signal may be present (“FS ready” signal).
