Sash Closure Position Switch
The sash closure position switch signals the display microprocessor that the sash
is open or closed allowing proper operation of the Blower, fluorescent or UV
lights. It is wired in the normally open configuration. If the switch does not
actuate properly when the sash is within ¼-inch of being fully closed, ensure the
switch follower is properly actuating against the weight. See Figure 6-7.
Sash Operating Position Switch
The sash operating position switch signals the display microprocessor that the
sash is open too far for proper operation, as shown in Figure 6-8. It is wired in
the normally open configuration. If the switch does not actuate properly when
the sash is within ¼-inch of its operating position, ensure the switch follower is
properly actuating against the weight.
