Torque measurement flanges are maintenance‐free.
11.1 Speed module maintenance
During operation and depending on the ambient
conditions, the slotted disc of the rotor and the
associated stator sensor optics can get dusty. This will
become noticeable when the polarity of the display
changes. Should this occur, the sensor and the slotted
disc must be cleaned.
1. Use compressed air (up to 6 bar) to clean the slotted
disc.
2. Carefully clean the optical system of the sensor with a
dry cotton bud or one soaked with pure spirit. Do not
use any other solvent!
