10.1 Torque flange maintenance
The torque measuring system is maintenance‐free.
10.2 Speed module maintenance
10.2.1 Magnetic speed measuring system
The sensor head and the pole ring contain plastic
components. You can clean these with a dry or
spirit‐impregnated cotton bud or cloth. Do not use any
other solvent!
10.2.2 Optical speed measuring system
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.
Use compressed air (up to 6 bar) to clean the slotted
disc.
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!
