6.5 Analog 4-20 mA Wiring, Configura-
tion and Registers
6.5.1 Analog 4-20 mA Wiring
The Analog 4-20 mA is an analog protocol that
has no sentences.
CHANNEL 1
• YELLOW --> VDC+
• GREEN --> VDC-
Yellow
V+ (Channel 1)
CHANNEL 2
• WHITE --> VDC+
• BROWN --> VDC-
White
V + (Channel 2)
CONNECTION INSTRUCTIONS
*Channel 2 connection is mandatory.
We connect channel 2* to the power supply, you
will have 10 seconds to connect channel 1 if you
want to use it in parallel. If not connected, only
the first of the named channels will be configu-
red.
The default configuration is the following:
• Channel 1 --> Address Mode
• Channel 2 -->Tunnel Mode
These configurations can be modified according
to needs thanks to the configurator that we have
available.
6.5.2 CONFIGURATION
To configure the equipment, Channel 2 (White/-
Brown cables) must be connected to the power,
Thus, the device will appear in the configurator
application (via Bluetooth).
At this point we can choose between different
modes:
• Speed Mode: In this configuration, speed
reading (0-45m/s), scaled in a range of 4-20mA,
is given through the channel we select.
Green
V - (Channel 1)
Brown
V - (Channel 2)

User manual
• Address Mode: In this configuration, wind
reading [0-359º] , scaled in a range of 4-20mA.
• Tunnel Mode: In this configuration you select
the combination of wind speed and direction. As
in many purposes it is not necessary to know the
direction of wind but the direction of the same,
the tunnel mode has been implemented.
Power consumption:
Ultra-Low-Power 4-20
@12-24V, 1Hz.
This protocol divides the measurement range
into two parts. When the wind direction is
between 0º and 180º the dimensioning used is
4mA-12mA;
while between the angles [180º - 359º] the
dimensioning is between 12mA - 20mA.
OPERATION
For the correct operation of the equipment, it is
required that channel 2 must be powered.
Once the device is connected, it will take approxi-
mately 10 seconds to start. Once the 10 seconds
have passed, the equipment will begin to launch
the relevant currents through the wires (Depen-
ding on the configuration established).

7. General information

7.1. General recommendations
Wind Speed Gust is that value that measures
abrupt and sudden change in wind speed.
Regarding mounting the unit, align the north
mark of the ULP towards the north.
Regarding mounting the unit, the mast head has
to be prepared for the mechanical installation.
Align the North mark of the Ultrasonic
Ultra-Low-Power to the north.
install the sensor in a location free from wind
perturbation, usually on the mast head.
Make sure to install the sensor in a location free
from anything that obstructs the flow of wind to
the sensors within a 2 meter radius, for exam-
ple, the mast head on a boat.
