5. Position the sensor unit on the cleaned area of the bearing bracket or drive
lantern. The sensor unit is optimally aligned when the x-axis of the sensor unit is
parallel to the shaft and the y-axis of the sensor unit is horizontal to the shaft.
6. Firmly press down the sensor unit.
7. Allow the sensor unit to dry on the bearing bracket or drive lantern to ensure
that the position of the sensor unit is not unintentionally changed during
subsequent mounting. The adhesive bond must be able to withstand slight
vibrations at the sensor unit. The waiting time strongly depends on ambient
conditions.
NOTE
At an ambient temperature between +25 °C and +30 °C, the supplied adhesive will
have sufficiently cured after approximately 24 hours. After 3 days, the adhesive will
have fully cured. Increased temperatures (e.g. +60°C to +120°C) accelerate the
curing process.
8. Check that the sensor unit is firmly positioned on the bearing bracket or drive
lantern; re-glue the sensor unit if necessary.
