Introduction
Safety
WARNING: Product servicing
The wind vane must be serviced in accordance with the Raymarine instructions provided. Failure
to do so could result in poor product performance, personal injury and/or damage to the boat.
WARNING: Electrical safety
Always switch off the power supply before you work on Raymarine products.
CAUTION: Electrostatic Discharge
The wind vane contains electrostatic sensitive components. Always observe the appropriate
precautions when handling, shipping, and storing these products. Failure to do this could result in
permanent damage to the equipment.

Parts list
The New Wind Vane parts are as follows:
:
Disassembly
To dismantle the wind vane:
1. Unscrew the locking ring (item 13) that secures the transducer arm (item 12) to the wind vane base (item 16), then sep-
arate these two items.
2. Carry out the disassembly instructions for the transducer arm and wind vane base.
Transducer arm
To dismantle the transducer arm:
1. Remove and retain the screw (item 1) that secures the assembled wind vane (item 2) and balance weight (item3) to the
top pod (item 4) shaft, then pull the vane and balance weight from the shaft.
2. Remove and retain the screw (item 11) that secures the anemometer cups (item 10) to the bottom pod (item 9) shaft,
then pull the cups from the shaft.
3. Unscrew the top and bottom pods from one another. If necessary, use a suitable tool to engage with the holes in the top
pod, to facilitate this.
4. Remove the O-ring seal (item 5).
5. Referring to
Figure 2 , insert a suitable tool (e.g. small screwdriver) into the breakout holes at the edge of the PCB
(item 6), then use the tool to GENTLY ease the PCB from its recess in the bottom pod.

Figure 2: Easing out PCB
6. Separate the PCB from the bottom pod just sufficiently to gain access to the upper connector (item7) on the transducer
arm cable assembly, then disconnect the connector from the PCB.
7. At the lower end of the transducer arm, press in both clips to release the lower connector (item 14) from the transducer
arm (see
Figure 3 ).
Figure 3: Releasing lower connector
8. Carefully guide the upper connector (item 7) on the transducer arm cable assembly, out of the bottom pod, then with-
draw the complete transducer arm cable assembly through the bottom of the transducer arm.
Wind vane base
To dismantle the wind vane base (item 16):
1. Using a suitable tool, remove and retain the nut (item 15) that secures the cable connector in the wind vane base.
2. Withdraw the transducer cable and connector through the bottom of the wind vane base.
Reassembly
Wind vane base
To reassemble the wind vane base:
1. Ensuring that the key on the transducer cable connector engages with the respective keyway on the wind vane base,
insert the connector through the bottom of the wind vane base into the correct position in the base.
2. Using a suitable tool, secure the connector in the base with the nut retained during disassembly. Tighten the nut until
its front edge is flush with the upper face of the connector.

Transducer arm
To reassemble the transducer arm:
1. Fit the transducer arm cable assembly as follows:
i. Arrange the upper connector of the transducer arm cable assembly as shown in
Figure 4 .
Figure 4: Cable/connector arrangement
ii. Feed the transducer arm cable assembly upper connector though the bottom of the arm, then up the arm and into
the bottom pod.
iii. Ensuring that the key on the lower connector of the transducer arm cable assembly is aligned with the keyway on
the arm, push the lower connector into the bottom of the arm, until both clips engage, to secure the connector in
the arm.
iv. Connect the upper connector of the transducer arm cable assembly to the appropriate connector on the PCB.
2. With the PCB connector adjacent to the cable entry hole on the top pod, place the PCB in its recess in the bottom pod,
ensuring that the cut-aways in the PCB engage with the respective protrusions on the lower pod.
3. Check the condition of the O-ring seal (item 5) and if it has been damaged, obtain a new one.
4. Fit the O-ring seal into the groove above the thread on the top pod.
5. Screw the top and bottom pods together and secure tightly, to ensure a waterproof seal. If necessary, use a suitable tool
to engage with the holes in the top pod, to facilitate this.
6. Ensuring that the flats on the anemometer cups and the lower pod shaft are aligned, slide the anemometer cups on to
the lower pod shaft then secure with the screw removed during disassembly.
7. Ensuring that the flats on the vane and the upper pod shaft are aligned, slide the vane to the upper pod shaft then
secure with the screw removed during disassembly.
Testing
To check that a wind vane is serviceable:
1. Connect the wind vane to a serviceable ST60 Wind instrument as in
Figure 5 .
Figure 5: Test connections
2. At the ST60 Wind instrument, check that the voltage between the red and black connections is 8 V dc, ±0.25 V:
3. Rotate the vane to the forward, starboard, aft and port orientations in turn and, at the instrument, check the sine and
cosine signals by measuring the voltages as follows:

4. SLOWLY rotate the anemometer cups and check that the voltage between the yellow and black connections switches
between approximately 8 V and 3.2 V, twice during each rotation.
