Cleaning Of The Interior; Cleansing And Adjustment Of The Speed Sensor / Light Barrier - h/p/cosmos 150/50 Operating And Service Manual

8.10.2

Cleaning of the interior

The interior should be cleaned every 6 months. The fans inside the machine and the moving running belt accumulate
dust and sweat. For this reason frequent interior cleaning is highly recommended for all treadmill models.
Depending on your model, lift up the motor hood or remove bellow from upper frame. Clean the interior of the running
machine by removing dirt with the help of a vacuum cleaner. Pay special attention to the ventilation net of the drive
motor and the cover of the frequency inverter. For devices with an external control unit, the internal space of the control
unit must be cleaned as well.

8.11 Cleansing and adjustment of the speed sensor / light barrier

Depending on the model, the firmware version and the manufacturing date, the machines may be equipped with...
no speed sensor (thus no cleansing required)
N
light barrier and incremental waver mounted without housing at the front (drive shaft) of the drive engine.
N
devices manufactured since approx. 2003 have hall effect sensors with metal toothed lock washer instead of light
N
barriers
only for oversize running machines with a running surface of 200/75 cm up to 300/125 cm and built before 2002: the
N
speed sensor is mounted in its own housing at the rear of the drive engine (drive shaft), thus it must not be cleaned.
The light barrier of the drive motor is a pulse generator for the control unit. The light barrier and the incremental disc
should be cleaned carefully with a cloth moistened with alcohol at intervals of 6 - 12 months. If the disc is housed, you
can also clean it with the help of a bristle brush soaked in alcohol, i.e. carefully cleaning the optical elements in between
disc and light barrier.
Alternatively, a spray of fat-dissolving liquid (e.g. braking detergent) with a thin spraying canal may be used. The
pressure of the detergent cleans the optics of the light barrier.
When adjusting the light barrier, take care to adhere to the
following guidelines for the spaces between the glass [3]
and the casing [4] of the light barrier: Cleft [1] axial approx.
1 mm/radial approx. 1 mm left and right according to
illustration above. The imaginary extension of the light
barrier should pass through the centre [2] of the motor
shaft.
Right hand side: The distance [1] between induction
sensors [2] and the cogwheel [3] must be within 0,8 mm
and 1,0 mm.
