3. Fork Sensing Spot
TF280-N/TF280-P fork sensing spot is shown as Figure 3 below. Considering
testing medium is water (S.G.=1 g/cm
3
) , sensing spot is at the fillister about
23mm from the tip. If testing medium has S.G. lower than 1g/cm
3
, sensing spot
would be above the fillister. In contrast, sensing spot will be below the fillister.
4. Magnetic Test
After the switch is installed and powered, magnetic test function can be
performed accordingly. The testing point is marked on the housing label. User
holds the magnet and moves it close to testing point, the output status will switch
from NO. to NC. or NC to NO. and red LED would switch ON or OFF while fork
continues to vibrate. When magnet is pulled away from the testing point, the
output status and red LED would return as default while fork continues to vibrate.
The purpose of testing is to confirm the wiring and functioning are correct.
