Each Sylkbus sensor includes a two pin side
connector with the packaging. The SKU
number of the Sylkbus sensor is C7400S. All
OA, RA and DA sensors are the same SKU
number. The sensor is set for the appropriate
type of sensing using the three position DIP
switch located on the sensor. OA position is
OFF, OFF, OFF; RA is ON, OFF, OFF and DA
is OFF, ON, OFF. During installation the
sensors are set for the usage desired.
NOTE: The protective film on the dip
switch is only necessary during the
factory assembly process. Simply
push through the film to set the dip
switches; this will not harm the
device.
Once installed, a sensor can be changed to a
different application by simply changing the
DIP switch setting.

WIRING
Module wiring in the field is terminated to the
four screw terminal blocks located on the left
and right sides of the unit. Module wiring at the
OEM factory is terminated via the header pin
terminals located on the left and right sides.
The header terminal pins and the terminal
blocks have common terminations for the
appropriate input or output.
Use Fig. 1 and Tables 1 and 2 to locate the
wiring terminals for the economizer module.

NOTE: The four terminal blocks are
removable. You can slide out each
terminal block, wire it, and then
slide it back into place.
