9 Maintenance
9.1 Maintenance schedule (preventive maintenance)
Initial maintenance interval is 1 year under normal circumstances. Maintenance is best planned in the
season when outside work is most comfortable.
For critical applications (where wind data is of major importance) under severe conditions, an initial
maintenance interval of 6 months might be considered.
The maintenance interval can be adjusted depending on the maintenance experience.
Periodic maintenance comprises inspection on the following points.

check ball bearings; contact Observator when they need replacement.

check cabling and cable support

check mounting; retighten if necessary

clean the sensor if necessary
Refer to section 6 for more information about the mechanical aspects. If the ball bearings require
replacement, the OMC-150 anemometer must be removed from its location.
The OMC-150 may only be opened and serviced by a qualified engineer certified by
Observator Instruments! An exchange service is available, contact your reseller or
Observator Instruments if you require maintenance.
9.2 Removing the OMC-150 anemometer from its location
1) First remove the vane unit and the cup unit.
The cup unit and the vane blade are made in light materials for optimum response on the wind. Both are
balanced to provide accurate measurement and to prevent vibration.
Take care not to damage the cup unit or the vane blade while mounting or disassembly.
The shafts of the OMC-150 anemometer and the inner side of the cup unit and vane unit are conical. After
removal of the capped nut and washer or O-ring, it might require a careful tap to loose the cup unit or vane
unit from its shaft.
2) Unplug the electrical connector. Prevent water ingress in the cable part plug during the period that the
OMC-150 anemometer is disconnected.
3) Loose the U-bolts and remove the OMC-150 body from its location.
