We recommend that the installation of the sensor in the hydraulic system of the forklift is
performed by an authorized lift truck dealer.
• Ensure that there is no pressure on the main cylinder line.
• The sensor is mounted with a T-piece in the high-pressure hose, between the valves and
the main lifting cylinder.
• The connection on the sensor is G¼” BSP male.
• Protect the cable from moving, sharp or warm parts with the supplied protective cover.
• Mount the T-piece so that the sensor and the cable connection are pointing downwards.
This will prevent air getting into the sensor.
Choose a place where you can mount the sensor:
• Mount the sensor in the pressure hose that steers the main lifting cylinder. In most cases
there is one cylinder which moves the carriage plate. The sensor is mounted as close to
the cylinder as possible.
• If the pressure hose splits to multiple cylinders, the sensor has to be mounted before the
split.
• Do not mount the sensor too close to the engine. Large differences in temperature can
influence the accuracy of the system.
• If the truck is used intensively, a piece of pipe or hose of ± 50 cm can be mounted
between the sensor and the T-piece. The sensor is sensitive to temperature differences.
If the moving oil becomes warm, the standing oil in this pipe or hose will remain cool and
the sensor will not be effected by temperature differences.
• Place the sensor close to the cylinder. There is often more room there and it is easier to
reach.
• Choose, if possible, a place to mount the sensor where there are the least steering and
safety valves between the sensor and the cylinder.
