Installation Procedure Mounting Sensor installation is most convenient when you use a Vaisala manufactured cross arm for mounting the sensor. 10 _____________________________________________________ M210293en-A Chapter 3 __________________________________________________ Installation Always mount the WAA151 Anemometer to the southern end of the cross arm. It is recommended that you remove the cup assembly to ease installation. Fit the 6-pin cable plug through the mounting flange at the end of the cross arm, then connect it to the sensor. The sensor fits to the cross arm in one position only. Face the product label south and mount the sensor to the flange by twisting. Note that the plastic washers (1) should be inserted between the flange and the sensor. Finally, tighten the screws (2) with an Allen key (3). Mount the cup assembly and tighten its fixing screw. 3. 4. To replace the ball bearings, follow the procedure below and refer to Figure 6 on page 19. Open the cup wheel fixing screw with a 2-mm Allen key. Remove the cup wheel assembly. CAUTION The cup wheel fixing screw has been treated with sealant. Do not remove the fixing screw to ensure perfect sealing after reassembling. 2. Loosen the hex nut of the connector (use a 22-mm tool). CAUTION Be careful not to bend the connector pins. 3. 6. Loosen the three pan head screws at the bottom of the sensor body (use a 7-mm tool). Remove the lower body assembly by pulling it straight outwards. Loosen the spacer screws with a 7-mm tool and disconnect the heating element outlet. Remove the printed circuit board including the optocoupler. CAUTION Do not twist or bend the connector. Loosen the fixing screw of the chopper disc with a 2mm Allen key and remove the chopper disc. Remove the external retaining ring (using narrowpointed pliers). Remove the spacer ring. 16 _____________________________________________________ M210293en-A Chapter 4 ________________________________________________ Maintenance 10.
