OPERATION
ALARMS
Wind speed and direction alarms each have their own set-point,
LED status indicator, and relay contacts. The Alarm Delay parameter
establishes time duration in or out of the set-point range needed for
the alarm to change state. Front panel LEDs indicate alarm status
during operation.
LED Off
= Alarm not armed and OFF. Relay open
LED Steady
= Alarm armed and OFF. Relay open
LED Blinking = Alarm armed and ON. Relay closed.
Audible beep if Sound parameter is enabled.
AVERAGING
When averaging is enabled, the front-panel AVG annunciator is
illuminated, and average wind speed and direction values are displayed
at intervals set by the Period (PEr) parameter. When averaging is
disabled, instantaneous wind values are displayed.
BRIGHTNESS
Adjust display brightness by pressing and holding the left BRIGHT
key for 1 second.
MAXIMUM or WIND DIRECTION DISPLAY
Either MAXIMUM WIND SPEED GUST or numerical WIND
DIRECTION appears during operation depending on Right Display
Window (dSP) parameter setting. Maximum gust may be reset during
normal operation by pressing and holding the RESET key for 1 second.
REMOTE DISPLAYS
The Marine Wind Tracker may be configured as a remote display by
setting the Sensor Input for serial input (InP=SEr) and connecting
the RS-485 terminals to a source providing a $WIMWV NMEA wind
speed and direction string. This may be any valid NMEA source
including another Wind Tracker operating as a master, a Young wind
sensor or interface sending the NMEA string, or a shipboard system.
With a Marine Wind Tracker as the NMEA source, use these settings:
MASTER: Sensor InP = any non-serial device.
REMOTE: Sensor InP = SEr
Connect one Wind Tracker master to up to 16 remote displays via
the RS-485 terminals as shown in wiring diagrams. Remote Wind
Trackers display exactly the same information as the master including
alarm states. MAX RESET and all display features are controlled by
the master unit only. Brightness can be adjusted independently at
each Wind Tracker display.
VOLTAGE OUTPUTS
Calibrated voltage outputs for wind speed and direction are updated
16 times per second. Wind Speed 0-100 m/s = 0.00 to 5.00 VDC.
Wind Direction may be scaled for either 0-360 or 0-540 degrees =
0.00 to 5.00 VDC by setting the Direction (dir) parameter.
4-20 mA INPUTS
The Wind Tracker accepts 4-20 mA Line Driver inputs with either
0-50 m/s or 0-100 m/s scaling (Ldi and Ld2 input settings). Connect
as shown in wiring diagram. The back-panel switch labeled 4-20 mA
must be in the UP position. 24VDC power is recommended for most
4-20 mA installations.
POWER CONNECTIONS
The Wind Tracker operates from a 12 to 30 VDC power source.
Power may be connected via the coaxial jack or terminals. These
are internally wired in together so DO NOT CONNECT MORE THAN
ONE POWER SOURCE AT THE SAME TIME. See wiring diagrams
for examples.
ERROR MESSAGES
Ldi Err
4-20 mA (line driver) signal is missing or outside
an acceptable range. Verify connections, signal,
and 4-20 mA switch in UP position.
SEr Err
Unit set to receive RS-485 serial signal (inP=SEr),
but no serial data detected. Verify NMEA source
is working. Verify connections.
