Verify the jumper and dip switch settings, Figure 28

YCWL chillers with Sporlan Electronic Expansion
Valves.
With the IB-G unpowered, select the input signal of
0-10 V by installing the supplied jumper to number 1
of the 5 pin locations shown in the left hand side of
EEV board. Set numbers 1 to 3 of the DIP switches in
accordance with the unit models. Set numbers 4 to 8 in
accordance with the table shown in “Figure 36 - Con-
denser Fan Locations” on page 161. For YLAA and
YCWL chillers, DIP switch number 6 must be set to
ON for a quicker EEV response.
