1. Introduction
This document provides guidelines for mounting and connecting the
static wind sensor WSS 500 series.
The WSS 500 series ultrasonic wind measuring system is a fast
responding and accurate general purpose system that is designed for
measurement of wind speed and wind direction on-board ships.
The sensor is based on three ultrasonic transducers arranged in a
triangle for measuring of wind speed and wind direction. By measuring
the time it takes for a set of ultrasound bursts to travel from each
transducer to the other two, the wind speed and direction can be
calculated.
The wind sensor is available as:
•WSS 550 with a built-in heater, which will automatically engage
when risk of icing occurs during low temperatures.
The WSS 500 series can be directly connected to the DEIF XDi-N
display indicator or WSDI-2 wind display to form a complete wind
system.
The WSS 500 series can also be used as wind sensor for previous
DEIF wind displays, such as WSDI and 879, in which case it must be
connected via an interface box.
The sensor may also be used as a component in a larger system; in
that case the system must have a free RS-485 or RS-422 input with
NMEA0183 capability.
Important: Be aware that the term WSS 500 series (or WSS) will
apply to the WSS 550 and the obsolete WSS 500.

Unpacking
The WSS 500 series sensor is delivered in a cardboard box.
Inside this box, the sensor is packed in a white foam box (called a
protection cap), which is supposed to stay on, until the sensor is
mounted in the mast.
This will effectively protect the delicate sensor heads.
The sensor is protected against ESD (static electricity), but it is
recommended to avoid static discharge through the connection wires
during installation.
Legal information and responsibility
DEIF takes no responsibility for installation or operation of the wind
measuring system. If there is any doubt about how to install or operate
the WSS 500 series, the company responsible for the installation or
the operation of the product must be contacted.
The units are not to be opened by unauthorised personnel.
If opened anyway, the warranty will be lost.
Do not remove the white protection cap or the tape
keeping it in place, until the sensor is mounted in the
mast!

2. Mounting the wind sensor
Placing of the wind sensor
Ideally, the wind sensor should be placed far from large objects that
might influence the measuring results; however, in practice this is
normally not possible on-board a ship. The best result is achieved by
placing the wind sensor at the top of a mast in the opposite end of the
superstructure.
Placing the sensor just above the superstructure is disadvantageous,
especially where the superstructure consists of wide side faces, over
which the wind is forced. This may result in turbulence, velocities and
wind directions that are out of proportion to the actual, undisturbed
wind speed and wind direction.
The wind sensor is intended for installation on a vertical socket or a
tube using the stainless steel tap mounting base. See the drawing
below for dimensions of the tap. The tap must not be removed from
the wind sensor, as this will damage the waterproof sealing and
the warranty will become void.
Keep away from the funnel.
Do not expose the plastic part of the wind sensor to any
torque when mounting the sensor. The tools used for
fastening are only to be applied on the actual tap.

Mount the WSS Remove the protective cap
Do not hit, squeeze or try to
remove the three black rubber
hoods!
To ensure that the display represents the
precise wind direction relative to the ship, the
wind sensor must be aligned correctly. That is,
when mounting the wind sensor, the arrow on
top (and bottom) of the white protection cap
must point ahead towards the stem of the ship
and be parallel with the centre axis of the ship.
Note: An arrow pointing ahead is also found on
the bottom part of the sensor itself.
Do not expose the plastic part of the wind sensor to any torque
when mounting the sensor; the tools used for fastening are only to
be applied on the actual tap.

Bird avoidance kit
The bird avoidance kit is designed to reduce the risk of birds landing
on the WSS 500 series sensors and thereby interfering with
measurements, or even damaging the sensitive ultrasonic transducer
heads. The black rubber heads are known to attract some birds’
attention because of the click-sound they give off.
The bird avoidance kit is mounted as standard on the WSS 500 series
and can be purchased as an optional extra to mount on previous WSS
versions.
Note that the kit does not provide complete protection against birds,
but especially large sea birds will not be able to land, while small birds
may still be able to squeeze inn. Small birds may interrupt the wind
measurement, but will not be able to damage the sensor.
The shape and location of the spikes has been designed so that the
interference with wind measurements is negligible.
Installation of the kit (retrofit only)
1. Position the metal ring with spikes
around the stainless steel top plate of
the WSS 500 series sensors. Position it
so that the spikes do not block the
direct paths between the three black
rubber heads; see picture.
2. Secure the metal ring using the M3x6
screw provided. It is recommended to
secure the screw from loosening due to
vibrations with a drop of Loctite® super
glue or equivalent (not included in the
kit) and tighten the screw all the way in.
When the kit is mounted on the WSS 500 series sensor,
more snow may be able to accumulate on top of the
sensor, and it may melt slower.
When the WSS 500 series is mounted on a horizontal
mast or surface, it must be raised at least 0.7 metres to
avoid birds sitting next to it – eating the sensor heads!

3. Cable connections
The wind sensor is supplied with 2 metres fixed cable. From factory,
the cable is connected to the sensor via a waterproof gland, and this
must not be replaced by another cable. The cable can be extended by
using the connection box kit or the IP67 connector kit (both optional).
In order to protect the wind sensor and the personnel in the best
possible way from lightning strokes, use a lightning rod installed with
the tip at least one metre above the wind sensor. The lightning rod
must be properly grounded in compliance with all applicable safety
regulations. The wind sensor cable screen and the extension cable
screen must be connected.
For further protection of the cable between the wind sensor and the
connection box, as well as the installation cable between the
connection box and the interface box, it is recommended to use a
metal conduit pipe. If the instrument is installed in a metal panel, this
panel has to be carefully earthed, as well as the instrument itself.
Suitable extension cable is available from DEIF. Alternatively, an
installation cable, for example UL2464 18AWG4C + AE, 4 × 0.75 mm2
screened, can be used. The maximum length is 300 m, and maximum
70 nF capacity between the signal conductors.

Troubleshooting a WSS/WSDI-2 installation
No.
Fault symptom
on WSDI-2
Cause/solution
1
No light in LEDs,
backlight or display
Aux. voltage is not available (18 to 31 V DC), or the WSDI-
2 is damaged.
2
Orange Error LED is
flashing
The WSDI-2 is defective, contact DEIF or a sales/service
representative.
3
Wind speed is “----“
and direction is not
changing
Cause: There is no valid wind data via RS-485 from the
wind sensor.
Check if the RS-485 port on the WSDI-2 is terminated.
See the WSDI-2 manual:
Check that “input select” is correct (0183 or r.183).
Use the WSDI-2 “Error functions” to find the type of error:
- Communication error (noise or bad connection).
- Error message from WSS sensor received (sensor may
be damaged or defective).
- LED indication for received and transmitted RS-485 data.
If there is no data communication:
- Check voltage from WSDI-2 terminals 7-8 and 9-8, it must
be 2 to 3 V DC on both. If not, the COM port may be
damaged in the WSS or WSDI-2 (lightning stroke,
insufficient lightning protection?), or
- Check the cable connection (broken or short-circuited).
4
Wind speed and
direction is dropping
out periodically
- Bad connection.
- The WSS is not grounded correctly on stainless
mounting tap.
- Heavy electrical noise or insulation error in the ship’s
electrical system (AC or DC).
- The WSS is not able to calculate valid data - snow, ice,
extreme rain or defective sensor head (lightning, bird
attack?).
5
Wind speed and
direction is dropping
out or instable when
outdoor temperature is
dropping below 5 °C
- The sensor is a WSS-L without heating - ice?
- The aux. power supply is not able to supply current
enough to drive the WSS heater. (24 V DC power supply
>2 A is recommended).
6
Wind speed is ”----“
and direction is not
changing when an
additional device
(VDR or Nav system)
is connected in
parallel on the RS-
485 port (A and B)
The added device is most likely overloading the RS-485
bus (only one extra NMEA input is allowed).
Termination on the RS-485 bus is missing.
The connection to the added device is damaged or short-
circuited.
Cable screen is wrongly connected, making a noise loop.
Solution: Use an NCI-1 NMEA converter (out) or an NMEA
buffer to solve the problem.

7
Wind direction is
wrong
Check that the sensor is aligned correctly. The arrow at the
bottom must point ahead and be parallel with the ship’s
centre line (see chapter 2).
8
No data on the NMEA
output
There must be correct wind data on the WSDI display.
NMEA data may be in the wrong NMEA format (see the
WSDI manual for more details).

5. Replacement of an old wind sensor
type 879.3c by the WSS 500 series
The special upgrade kit should be used when an existing 879.3c
dynamic wind sensor is to be replaced with a new WSS 500 series
sensor and connected to a display type 879.50/879.521 or WSDI.
The interface box type WSI is needed to translate the RS-485 data
signal from the WSS 500 series into a speed and direction TTL signal
appropriate for the 879.50/879.521 or WSDI display.
Remove the tap for the old sensor 879.3c and mount the new sensor.
Notice that the tap is fixed on the new sensor and is not to be
removed.
Follow the instructions in chapter 2 to mount the new WSS 500 series
sensor correctly.
The existing cable can be used. Before mounting the new sensor
using the existing cable, remember to disconnect the cable from the
wind display and check that the cable is not damaged.
The sensor is equipped with a 2 m cable, this cable is connected to
the existing cable using a junction box (normally already mounted).
