[. . . ] Refer to Figure 2 on page 9. 0204-041 Figure 3 Recommended Mast Length on the Top of Building The recommended minimum length (marked with the letter h in Figure 3 above) for the mast that is installed on the top of a building is 1. 5 times the height of the building (H). When the diagonal (W) is less than the height (H) the minimum length of the mast is 1. 5 × W. Installation Procedure Mounting Sensor installation is most convenient when you use a Vaisala manufactured cross arm for mounting the sensor. 10 _____________________________________________________ M210294en-A Chapter 3 __________________________________________________ Installation Always mount the WAV151 Wind Vane to the northern end of the cross arm. It is recommended that you remove the vane assembly to ease installation. Fit the 10-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 north 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 vane assembly and tighten its fixing screw. 3. 4. 5. 0204-042 Figure 4 Mounting of Wind Sensor VAISALA__________________________________________________________11 User's Guide ________________________________________________________ Alignment The wind vane does not need any alignment after mounting when a Vaisala cross arm is used. To replace the ball bearings, follow the procedure below and refer to Figure 6 on page 19. Open the vane assembly fixing screw with a 2-mm Allen key. The correct screw is the lower one shown in Figure 6 on page 19. Remove the assembly. CAUTION The vane assembly fixing screw has been treated with sealant. Do not remove the fixing screw to ensure perfect sealing. 2. Loosen the hex nut of the connector with a 27-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 with 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. CAUTION Do not twist or bend the connector. Loosen the fixing screw of the code disc with a 2-mm Allen key and remove the disc. Remove the external retaining ring (using narrowpointed pliers). Remove the spacer ring. 16 _____________________________________________________ M210294en-A Chapter 4 ________________________________________________ Maintenance 10.
