+0.5/-7V. If the voltage level is OK, then disconnect the brown and orange wires in the connection
box. Check the voltage level on the brown and the orange wires with respect to the black wire on
the cable end connected to the interface box. The voltage level measured on the brown wire must
be 2.5V ±0.5V DC, and the voltage level measured on the orange wire must be 2.5V DC ±0.5V. If
the voltage levels are OK, the fault is related to the wind sensor and a replacement is necessary.
On the other hand, if the voltage level differs from the above, the fault is related to the cable.
Cable failure
If the read-out of the wind speed is zero and the direction is indicated at 0-90-180-270° every 0.5
second, the fault is probably a cable break or short circuit in the cable.
The display indicates wrong wind direction
Check the position of the wind sensor. An arrow is printed at the bottom of the wind sensor, check
that this arrow is pointing directly to the ship’s stem. If this is OK, the fault can be related to the
display; check the position of the jumper setting on pin header JP1, see the section “Read-out of
wind direction”.
No data available on the NMEA output
If the wind direction is interrupted, the NMEA output stops. Check the wiring on terminal 4 on the
display, and check the wiring on terminal 11 (D) on the interface box.
