3.5 Cable entries
If the sensor is mounted in correct manner and connected with the right cable (accessory), you can attach the
wires to power supply and signal outputs to data acquisition equipment (computer). The sensor requires a 12-pole
CONINVERS plug connector of the series designation „TC“ (Ordering No.: TC-12S1N128055). The cable shield should
be connected with both ends at the ground wire (PE).
To reduce the risk of inductive interference the sensor must be properly grounded (screening on both sides).
3.6 Start-up
After having finished the electrical and mechanical installation work of this item as mentioned in this manual and other
related instructions the wiring should be checked once again before switching on the mains for the whole measuring
system. When the power supply of the sensor is switched on, the sensor automatically sends cyclic data.
3.7 Functional test
When the system installation is completed a simple performance check as mentioned here can be carried out:
•
To check the sensor for wind direction the wind vane is set in the directions NORTH-EAST-SOUTH-WEST and
fixed in these positions for a while. Accordingly to this directions the following values must be displayed: N or 0°
(360°), E or 90°, S or 180°, W or 270°.
If the display does not correspond to the actual positions of the wind vane, the sensor must be aligned again and
the cable connections checked.
•
When stopping the cup rotor carefully by hand at its axis, the displays must indicate a value of 0 knots (m/s).

Service and maintenance
4.1 Replacement of spare parts
REPLACEMENT OF EXTERNAL PARTS
When working under harsh conditions it may be necessary that the following consumables have to be replaced.
Cup Rotor:
After bending away the washer, the hexagonal screw can be loosened with a wrench size SW 27. The faulty
cup rotor can be removed together with the washer.
The new cup rotor has to be mounted in such way that the concave parts of the cups are always on the right side
enabling an
anticlockwise rotation
.
After replacement of a cup rotor it will always be necessary to use a new washer in order to fix the rotor safely. New
balancing will not be required.
