Installation requirements of the Yanmar standard accelerator sensor:
1. To protect against water and corrosion
• Ensure no water is trapped inside the sensor axis or connector of the sensor.
• Install the sensor in such an area that is not subject to steam or high-pressure water for cleaning.
• Do not strain the harness. Doing so may damage waterproof seals, causing water to intrude into the
harness.
2. To protect against vibrations
To prevent abrasion or deterioration of potentiometer resistance elements and disconnection of the
harness, observe the following:
• Install the sensor in such an area that is not subject to vibration of more than 2.4 Grms (5 to 1000 Hz in all
directions).
• Install the sensor so that no resonance is produced.
• Install the sensor so that the sensor lever arm does not suffer vibration due to vibrations of the accelerator
lever or wire cable. (Secure the accelerator lever and wire cable to the same member, for example).
Ensure the fluctuation in output voltage of the accelerator sensor due to vibrations falls within a range of
1.6 mVp-p or less.
3. To protect against noise
• Ensure the cable length between the E-ECU and the accelerator sensor does not exceed 5 m.
• Do not lay the cable near noise sources such as large power devices. If it is inevitable to install the cable
near noise sources, use a twisted or shielded cable.
• Ensure the fluctuation in output voltage falls within a range of 50 mVp-p or less.
4. Others
• Do not use sensors that have suffered drop impact or visible damage.
