4-20mA and Voltage Sensors
Aranet offers different transmitters that can be connected with third-party sensors and thus integrated into the Aranet ecosystem. Transmitters themselves are battery-powered, but can also be connected to mains electricity to power the third-party sensor.
It is possible to pair the transmitter to the base station with or without the sensor connected.
To pair the transmitter, the transmitter must be near the base station (< 20 m).
When installing and placing the sensor, note that the cable must be routed in a manner to obtain a "water/drip loop", for water to drop off.
Do not stress the cable
Pairing with batteries inserted
Pairing the sensor with the battery ensures an uninterrupted signal to the base station during the whole installation process, as well as in case of an electricity outage or sensing element failure.
Unscrew and take off the transmitter's lid.
Have the transmiiter and 1x AA battery ready.
Open the base station WebGUI (make sure, that you have the latest firmware version)
Open the section "Sensors" and there choose the preferable measurement interval.
Click the “Pair sensor” button on the computer screen and then immediately insert the batteries or insert batteries and click the “PAIRING” button on the transmitter (right corner).
The sensor will be paired and appear with a green corner
You can finish your sensor setup and screw the lid back.
Pairing with mains power, without batteries
Unscrew and take off the transmitter’s lid.
Connect the power cable to the transmitter.
Connect it to the power mains.
Open the base station WEB page (ensure that you have the latest firmware upgrade).
Open the section “Sensors” and there choose the preferable measurement interval.
Click the “Pair sensor” button on the computer screen and then click the “PAIRING” button on the transmitter (left corner).
The sensor will be paired and appear with a green corner.
You can finish your sensor setup and screw the lid back
N - Neutral
Blue
L - Live
Brown
GND*
Green/yellow
The GND wire should be clipped at the end
If needed, the sensor can be either placed on a clean surface or attached to a wall.
Unscrew the transparent lid of the transmitter.
To attach the transmitter to a wall, use the 4 mount holes in each corner of the body transmitter.
Screw the transmitter to the wall.
Attach the transparent lid back.
The 4-20mA Sensor can be used for current measurements (within a range of 0 - 30 mA) and the Voltage Sensor - for voltage measurements (within a range of -32 to +32 VDC).
Under the “Sensors” menu, it is possible to enable conversion from mA/V to other values depending on the mtransducer type connected to mA/V Sensor.
If required, switch the Conversion on, and use the drop-down menu to choose a predefined Dimension and Unit. If the required Dimension or Unit is not in the list, choose “Other” as the Dimension and input your own measurement unit.
Define the reference values for two measurement points (i.e., sensor’s min/max voltage). For example, set 0 V equal to 100 of your units and 32V equal to 1000 of your units. The values will then be linearly calculated according to these two reference points.
