FBD FBD562, Nstallation And Operations Manual, Page: 37 / 56

NOTE:
H2O readout will be 15-20
psi higher on the readouts.
Keep regulated pressure at
70-72 psig.
(Item 13.34 continued from previous page.)
F. Syrup Transducer problem. F. Check syrup pressure readouts
for 70-72 psig. If not within 2 psi,
adjust regulator and/or check
transducer. Replace transducer, if
necessary.
G. Lower Board problem. G Check lower power board for +5,
+15, and –15 indicator lights. If
green lights are not energized,
replace board, if necessary.
H. Upper Board Problem. H. Circuits within Main Control (Upper)
Board electronics read transducer
pressures. Replace Main Control
(Upper) Board, if necessary.
