4. Assembly

Refer to Figure 1, Exploded View.
When handling any of the PCBs, linen or other suitable material ( not nylon)
gloves should be worn if an anti - static mat and grounding strap are not
used. If gloves are not available, handle the PCB by the edges only.
1. Solder the SeaTalk cable (6) to the main PCB (7) contact pads (see
detail, Figure 1 for cable colours and connections)
2. Lift the top bars of main PCB connectors PL1 and PL2 and insert the
ribbon cables (5). Press the bars down to secure the cables (see detail
in Figure 1). For both connectors on the PCB, the coloured side of the
cable faces the centre of the PCB
3. Slide the PCB into the main body (8) from the top (wind vane end),
threading the lower ribbon cable through as the PCB enters. The PCB
is tapered and fits narrow end first
4. Check that the O - rings (3) on the anemometer (10) and wind vane (2)
heads are not damaged, distorted or loose and are free of grease and
dirt. Replace or clean as necessary
5. Plug the lower ribbon cable (5) into PL1 of the anemometer PCB (9)
(see detail in Figure 1), ensuring that the cable is not twisted. The
coloured side of the cable faces the outer edge of the board
6. Push the anemometer head (10) into the main body (8), ensuring that
the head is fully home and the ribbon cable (5) is not twisted
7. Plug the lower ribbon cable (5) into PL1 of the wind vane PCB (4) (see
detail in Figure 1), ensuring that the cable is not twisted. The coloured
side of the cable faces the outer edge of the board
8. Push the wind vane head (2) into the main body, ensuring that the head
is fully home and the ribbon cable (5) is not twisted
9. Fit the cup assembly (11) to the lower shaft and the wind vane (1) to the
upper shaft. Insert and tighten the grub screws (12). Check that the
vane and cups rotate freely in both directions.
