2. Installation Procedure for the WLS350
WARNING: These basic installation instructions are given based on the installer having
previous experience in the servicing and maintenance of machinery. General safety
precautions should be undertaken similar to carrying out maintenance on this type of
machinery. Inexperienced personnel should not undertake this task if they are unsure of
the safety precautions necessary.
2.1.
Fitting the Display to the Operators Cabin
Select a suitable location and using the mounting bracket, mount the display. Allow plenty of
room for the cable at the rear of the display. A minimum of 3" should be provided between the
display and any surface for adequate cable routing and connector removal.
DO NOT DRILL OR WELD ONTO ANY PORTION OF A R.O.P.S. or F.O.P.S.
A bracket, however, can be bolted onto a lock striker plate, window frame aperture or turret
support. Consider wiring and cabling when choosing a mounting position. Consideration should
also be given so the instrument does not impede operator vision. Vibration should also be taken
into account so as not to damage the hardware.
2.2.
Installing the Pressure Transducer
PRECAUTIONS
1. Lower Boom completely to the ground and stop the engine.
2. Operate the tilt, and lift levers to ensure no residual pressure is present in the hydraulic
system. Refer to Owner's Manual to relieve pressure.
3. Remove the hydraulic tank filler cap to remove any pressure from the oil reservoir tank.
4. Slightly loosen any "easy to get at" fitting in the piston side of the lifting circuit to ensure
no pressure is present. The transducer is to be fitted into the lifting circuit of the hydraulic
system between the control valve and the lifting cylinders. See Appendix A for hydraulic
information. Connect appropriate adapter to allow transducer to be mounted in a safe
position. Avoid areas that are subject to oil and water. Do not run cable through
articulated or moving areas of the machine. Tighten the fittings. Start the engine and lift
the forklift / boom approx. ½" from the ground. Check for leaks. Bleed the air from the
line by repeatedly raising and lowering the forks / boom.
2.3.
Wiring the WLS350 to the Forklift or Loader
The WLS350 fits machines that have 8-32Vdc power supply. Voltages other than this may
require a voltage converter.
RED = Switched supply. Can be tied to Ignition/Accessory or its own circuit to turn the system
on.
BLACK = Ground
