7 Pressure Sensors
Although the pressure sensors/transducers are exactly the same, their programming is different therefore it is important
to connect them in the instructed locations. If upgrading from a Wylie W1258 or i3500, simply disconnect existing
pressure sensors and replace by the new. We have supplied two possible adaptors, but since it is difficult to tell what is
already on the machine, you may need to contact your local hydraulics supplier for the proper fitting if these are not
suitable.
The new pressure sensors are CANbus and will connect directly into the wiring scheme without passing through an
interface box. See wiring diagram.
**Pressure transducers must be installed when the boom lift cylinders are fully retracted.
Single cylinder crane
: Connect the bore side pressure sensor p/n 33C4020-B0 to the bore side and the rod side pressure
sensor p/n 33C4020-B1 to the rod side
Dual Cylinder crane:
Connect the two bore side pressure sensors p/n 33C4020-B0 and 33C4020-B2 to the bore side and
the rod side pressure sensor p/n 33C4020-B1 to the rod side.
**Do not forget to bleed the lines (let the air out) as remaining air will affect the load reading.
Bore side:
Run cable along hydraulic hose
