a) Press and release the 'RESET' key then immediately press and hold it for three seconds. If the "Adjusting
TMP" message is present allow it to expire. If a TMP alarm occurs repeat the RESET sequence once
again then continue.
b) Is ACFS 3.5 or greater?
Yes See procedure number
No See procedure number
F- 11.0.3 CHECK CFS ELECTRONICS (ACFS)
a) Referring to the Figure (right), unplug the CFS transducer's
connector (labeled #10) from distribution board position
labeled x10, "CFS".
IMPORTANT!
b) To avoid time consuming error, using the
screen's clock (upper right), allow up to five minutes (ACFS
response is NOT instantaneous).
c) Does ACFS increase to 9 or greater?
Yes a) CAREULLY return the CFS transducer #10 to distribution board position "CFS".
b) See procedure number
