To verify correct healthy functionality of each individual import valve logic.
To verify correct healthy to trip condition of each individual import valve logic.
To verify the functionality of a fuse failure.
Method Of Test
4.2.8.1
Simulate level switch probe healthy by connecting an E&H Liquiphant
level probe as Specification SI277001_SPC to incoming terminals. Ensure the
probe tip is not covered and the internal switch unit is set to max/>0.7.
4.2.8.2
Simulate all manual shutdown systems healthy by applying a link to
incoming terminals.
4.2.8.3
Simulate all valve limit switch feedback as valve closed by applying a
link to incoming terminals.
4.2.8.4
Momentary depress reset pushbutton, confirm all safety relays energise.
4.2.8.5
Confirm 24Vdc present at all XSV outgoing terminals.
4.2.8.6
Disconnect BPCS Open Command Wire Link. Confirm associated XSV
outgoing terminals de-energised whilst removed and energised when connected.
4.2.8.7
Remove BPCS Open Command Wire Link, apply a 24Vdc supply to

energised when BPCS Open Command 24Vdc removed.
4.2.8.8
Remove BPCS Open Command Wire Link, apply a 24Vdc supply to
incoming BPCS Open commands terminals. Confirm associated XSV outgoing
terminals energised whilst BPCS Open Command 24Vdc applied and de-
energised when BPCS Open Command 24Vdc removed.
