Verify the jumper and dip switch settings, shown in
Figure 35 on page 106, during a chiller start-up for
YLAA, YCWL and QWC3 chillers with Sporlan Elec-
tronic Expansion Valves.
With the IB-G unpowered, select the input signal of
0-10V 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 35 on
page 106
. For YLAA, YCWL and QWC3 chillers,
DIP switch number 6 must be set to ON for a quicker
EEV response.

Verify that the unit’s protective ground terminal(s) are
properly connected to a suitable grounding point. En-
sure that all unit internal ground connections are tight.
