1-107
NOTE
In following step, SHP required and % N2 were determined in
previous step a.
c. Using formula, Torque = (SHP required X 411), determine torque required.
% N2
d. Advance N1 master hydronic control until torque, determined in step c. for maximum power, is ob-
tained.
e. With N2 master hydronic control in its maximum position and water in master hydronic control set
to provide maximum power, adjust N1 master hydronic control until a Wf of 1750 phr is indicated.
NOTE
In following step, N1 speed should gradually increase to a maxi-
mum value within tolerance range shown below.
f. Using water in master hydronic control, unload engine until overspeed governor degreases Wf to 1685
to 1715 phr.
