Each node is compatible with only one type of probe, so make sure you have chosen the right type when ordering. The Single Channel Node is part of the Move Solutions range of LoRaWAN products for monitoring purposes; as such, the node needs a LoRaWAN gateway (such as the Move Solutions Gateway Pro) to connect to the Move Cloud Platform™.

A label identical to the one on the packaging is affixed on the side of the Single Channel Node. On the back of the Single Channel Node another label specifies the product code and type of the Single Channel Node. Refer to the following chapters for more information on Single Channel Node types.
Annex C. Tighten the cable gland and close the lid. If the gateway is already running, you can start checking your data on the Move Cloud Platform™ within a few minutes. Otherwise, a maximum time of 30 minutes after the installation of the gateway is required before the node can be viewed on the platform.
Wiring a probe CAUTION • When connecting a probe to the node, disconnect the batteries. • Before connecting a probe, verify that it is compatible with the type of node you are planning to connect it to. This means checking that the type of node is suitable to read the output of the probe, and that the voltage supplied by the node is in the range of acceptable supply voltages for the probe.
CAUTION • Before reconnecting the batteries after wiring the probe, check the wiring to avoid damaging the node, the batteries, or the probe due to incorrect wiring. 6.1 Wiring instructions Single Channel Node | 4 – 20 mA The Single Channel Node supports 4-20 mA probes with 2 or 3 wires. Other types might be possible to read with an external power supply.
4-20 mA | 3 WIRES The wires in 3-wire 4-20 mA probes are usually: • A power wire (often called ‘VCC’, ‘Power’, ‘E+’), usually red • A ground wire (often called ‘GND’, ‘E-‘, ‘0V’), usually black • A signal wire (often called ‘Signal’, ‘S’, ‘S+’), other colors, often white or green The wires should be connected as follows: Position in the terminal 4-20 mA | 3 wires Probe connectors...

6.3 Wiring instructions Single Channel Node | Voltage Output (5V) This node supports probes that can work with a power supply of 5 VDC, and output a signal between 0 and 5 Volts, referred to the same ground as the power supply. These probes usually have 3 wires, sometimes 4.
Page 26
6.4 Wiring instructions Single Channel Node | Voltage Output (12V) This node supports probes that can work with a power supply of 12.3 VDC, and output a signal between 0 and 12 Volts, referred to the same ground as the power supply. These probes usually have 3 wires, sometimes 4.
Page 27
6.5 Wiring instructions Single Channel Node | Potentiometer These probes typically accept any supply voltage and give a voltage output between 0 and the supplied voltage. These probes usually have 3 wires. CAUTION • The naming conventions and color code of wires is not standard and can vary significantly from probe to probe and manufacturer to manufactu- rer.

6.7 Wiring instructions Single Channel Node | Pt100/Pt1000 The Pt100 and Pt1000 probes consist of a platinum resistance whose value depends on the temperature. By measuring the resistance of the sensor, it is therefore possible to trace its temperature. These types of probes typically have 4 wires. These wires are combined in pairs marked with the same color, usually white and red.
Page 30
6.6 Wiring instructions Single Channel Node | NTC These types of probes typically have 2 wires. These wires can be swapped without consequences. Here we will call “NTC+” the first wire, and “Signal -“ the other. The wires should be connected as follows: Position in the terminal Vibrating Wire Probe connectors...
In Programmed Acquisition, the Single Channel Node starts acquiring data once every given period, which can be set by the user through the Move Cloud Platform™. The Programmed acquisitions are aligned to 00:00 UTC. This means that if the acquisition cadence is set to 2 minutes, the acquisitions will start at 00:00, 00:02, 00:04, 00:06 UTC and so on.
During the warmup phase the node does nothing and waits for a predetermined time, which can be managed via the Move Cloud Platform™, to give time to the probe to turn on and make sure that the data that is read is valid. For simpler probes a warmup of 1 second may be sufficient, while for more complex probes - especially 4-20 mA 3-wire, Voltage Output (5V) and Voltage Output (12V) - the warmup time can vary greatly.
After that, the node will use this information to reduce the time and power required for the next acquisitions. Sometimes the vibrating conditions of the probe may prevent the node from latching to the correct frequency. In that case it’s important to check the minimum and maximum frequencies and the advanced options on the platform.
Installation on site When installing the Single Channel Node, it is important to follow some basic prescrip- tions to ensure the correct operation of the product. First, locate the antenna on the inside of the node. The antenna is on the shorter side of the node, on the inner side of the wall were the label is affixed.
Page 35
Avoid, if possible, to locate the gateway vertically above or under the node. If this cannot be avoided, it is best to keep the two antennas perpendicular to one another.

Wire and so on), • Converted data allows you to apply a variety of formulae (custom conversion) or choose a probe that has previously been validated by Move Solutions and apply a pre-configured conversion. • Warmup allows you to select the amount of time that the node must wait between turning on the probe and starting to acquire.
9.2 Specific settings for 4-20 mA Single Channel Node To setup the conversion of a 4-20 mA probe, the platform asks for 4 parameters, which are the minimum and maximum values in mA, and the relative conversion of each of the values. By doing so, the platform constructs a straight line between the two points to obtain a conversion rule.
Page 39
Simply put, a load cell that ouputs 1.4 mV/V with 1 kN of load on it has a gain or sen- sitivity of 1.4 mV/V/kN. This is the parameter that needs to be input on the platform. Note that the easiest way to recognize this parameter is its unit of measurement, which is mV/V divided by the unit of measurement of the probe.
9.4 Specific settings for Voltage Output (5V) and Voltage Output (12V) Single Channel Node To setup the conversion of a Voltage Output probe, the platform asks for 4 parame- ters, which are the minimum and maximum values in V, and the relative conversion of each of the values.
The formula is: Omeas Rmeas Where is the output measurement, is the raw measurement, and Omax Omin are the parameters input by the user. For example, a potentiometric crackmeter with a fullscale measure of 100 mm will Omin Omax have = 0 mm, = 100 mm.
Page 42
LINEAR FORMULA The simplest way to convert the frequency from the vibrating wire probe to a geotech- nical unit of measurement is applying a conversion factor to the corresponding linear digit. The linear formula requires the user to insert the conversion factor (referred to as “gain”...
TEMPERATURE COMPENSATION Vibrating wire probes often include an NTC thermistor to measure the probe’s tempe- rature as this information can be used to compensate thermal effects on the measure. In the Probe configuration tab, after configuring the auxiliary NTC and its conversion formula it’s possible to activate the temperature compensation function.
9.8 Specific settings NTC Single Channel Node NTC probes readings in Ohms are usually converted to Celsius degrees through the Steinhart-Hart equation. The equation requires the user to enter three parameters, usually called The equation is as follows: These parameters should be available on the calibration report, datasheet or user manual of the probe.
In this event, only use the prescribed batteries. For information on how to provision said batteries, please contact a Move Solutions representative. If the prescribed batteries are unavailable, or provisioning is not possible, consult a Move Solutions representative to find a viable alternative.
Annex A About Warmup Warmup is the time required for the probe to correctly turn on and respond with a valid data. The nature of the data can vary greatly depending on the technology employed on the probe: simple analog probes such as thermistors, potentiometers and such usually have a very fast warmup that is almost impossible to notice.
Annex B Optimizing battery life The life of the Single Channel Node’s batteries depends heavily on the needs of the probe connected to it. The main consumption factors for the node are: The number of acquisitions over a given time The duration of the acquisitions The average current consumption of the probe Whether the accelerometer is active or not...
Annex C Field test function Once the sensor has been connected to the node and the batteries have been recon- nected, it is possible to carry out a first reading test to verify correct installation, even in the absence of the gateway. The procedure for this test function is the following: Press the RESET button and wait for the two LEDs to turn on.
Page 50
HOW TO INTERPET THE DATA The data is represented on four digits by flashing first of the green LED, then of the red LED, then again of the green LED and then again of the red LED. A series of quick flashes means ‘0’, otherwise each LED flashes a number of times equal to the corresponding digit.
Annex D Zeroing One useful feature on the Move Cloud Platform™ is the zeroing function, located in the Acquisition parameters tab, in the Settings menu. By clicking on the Zero the measure button, the last measure from the probe is saved and used as a tare for future (and past) measurements.
Page 52
Fmeas Tmeas Where are the current frequency and temperature measure- Finstallation Tinstallation ments, while are the frequency and temperature measurements when the probe was first installed. This case is covered automatically by zeroing, too, by pressing the Zero the measure button after correctly installing the probe.
Annex E Troubleshooting Here we seek to give a few pointers to the most common misfunctions and Suggested countermeasures. WARNING • Remember to always disconnect the batteries before physically operating on the node. THE SINGLE CHANNEL NODE IS OFFLINE First of all, check whether the gateway is online. If the gateway is offline, refer to its manual or to the customer service to solve the problem.
PROBE DATA IS LOWER THAN EXPECTED There may be a problem with warmup, try a longer warmup time. Check the raw data as well to make sure it’s not a conversion problem. 4-20 mA: READING IN RAW MODE IS CLOSE TO 0 mA Check the wiring.
Page 55
POTENTIOMETER: READING IN RAW MODE IS CLOSE TO 100% Check the wiring. The signal wire might be touching the power wire. VIBRATING WIRE: READING IN RAW MODE IS STUCK AT 100’000 Hz The probe is giving a very weak response. Check the wiring: the coil wires might be connected incorrectly.
