dirlimit
Threshold limit for wind direction change in degrees. If the wind direction
change is below the threshold, direction is considered unchanged. Range:
0 ... 180. Default value: 3.
spdlimit
Threshold limit for wind speed change in m/s. If the wind speed change is
below the threshold, speed is considered unchanged. Range: 0.0 ... 10.0.
Default: 0.0.
sdpvoltlimit
Threshold limit for minimum current taken by the anemometer (roughly in
50 mA units). Below the limit, the sensor is considered absent and MWV
speed value is given as null field (,,). Setting
spdvoltlimit
= 0
deactivates the function. Default value: 0.2.
dirvoltlimit
Threshold limit for minimum current taken by the wind vane (roughly in
50 mA units). Below the limit, the sensor is considered absent and MWV
direction value is given as null field (,,). Setting
dirvoltlimit = 0
deactivates the function. Default value: 0.2.
value Value for the option
If you have an old version of WAC155 (L47101 or older) and a new version of
WAV151 (L47101 or newer), you must change the
dirvoltlimit value to 0.15.
Typical commands:
SETALR ACTIVE 1 (activates the alarm functionality)
SETALR DIR 60
(alarm if wind vane is static for 60 seconds)
SETALR SPD 60 (alarm if anemometer is static for 60 seconds)
SETALR CALM 1440
(alarm if both sensors are static for 24 hours)
For WA25 series sensors, you must deactivate the functionality of the following
parameters by setting the parameter value to 0:
• spdvoltlimit
• dirvoltlimit
Deactivating the
SETALR
command does not deactivate
sdpvoltlimit
or
dirvoltlimit
. You must deactivate them separately.
