Hello Nick,
We need some clarifications on the interlock checkout procedure:
1.for the tasks in page 14 called "software quench 1st threshold Controlled ramp down" and the following comparator tests; the procedure says "Disable the PLC QD fast ramp down by temporarily raising the thresholds to 250 mV"; under that for each comparator procedure it says " Verify the Fast Ramp Down was initiate" Should it be Verify the controlled Ramp Down was initiate?
2. On page 16 for comparator 7,8,9 and 10 there is a step added (Verify the dump contactor open) that is not in the procedure for the comparator 1 through 6. Should this extra step be skipped?
Please let us know about this clarifications, as they are preventing the completion of this tasks , thanks.
Pablo Campero
