FAQ

The device’s battery lasts a short time after a few months of use, what’s happening? If lead-acid batteries are used, they have a lifespan of approximately 300 cycles and an average of 9-10 months, so it is recommended that they be replaced periodically after this time or if signs of capacity decline are observed. It is important to keep in mind that environmental operating conditions, such as the temperature to which they are subjected, play a role in degradation.

I have installed the device with a 12V LiFePO4 battery, but it has run out and now shows 0V, what should I do? Lithium batteries, in general, must include a system that monitors each cell individually (BMS) to avoid operational risks, such as overvoltages, extreme temperatures, overcurrents, etc. Therefore, if any of the operating situations described above occur, the BMS intervenes and disables the battery, stopping it from receiving voltage at its output. This situation can be temporary; for example, if the temperature is very low, the battery will automatically restore power when the temperature rises above 0°C. However, if overdischarge occurs, the BMS disables the battery until a charge is applied again. Once it receives power from the solar panel, it will restart charging, activating the battery and the device.

The device has stopped communicating and has good coverage. Check the battery and solar panel levels. Typically, if the loss of communication lasts for a prolonged period, it may be due to a low battery charge, and communication will not resume until it recovers. Additionally, the device enters power-saving mode when it detects that the battery drops below 40%, where it stops communicating until it recovers enough power to restore normal communication frequency.

The battery is discharged despite having power from the solar panel. Check the solar panel for dirt and orientation, as well as for shadows from trees or similar, to ensure 5-6 hours of good radiation. A 12V/10W solar panel in good condition should deliver a voltage greater than 20V in an open circuit and 500mA in a short circuit, so another point to check would be these values.

Can the solar panel be replaced with a voltage adapter? Yes, a 24VDC/0.5A AC/DC adapter can be used as a replacement for the solar panel if the device is to be installed in a location where there is grid power.

Can the device be powered with a 12V adapter? Yes, but with two exceptions:
– Must be able to supply at least 2A of current.
– You should either provide 13.8V to prevent the device from entering power saving mode, or configure the device to tell you that you’re using a power adapter instead of a battery, thus disabling power saving mode.

What types of valves can I connect? Any latch type valve whose firing voltage is between 3.3V and 23V with a maximum current of 2.7A.

How can I control the ignition of a pump? Simply connect a latch-type relay to one of the valve outputs and its contacts will be able to attack the pump control contactor.

How many irrigation programs can it manage? The device is capable of storing up to 192 irrigation programs for agricultural mode and 32 programs for gardening mode (sequential irrigation).

General Questions

What types of analog sensors can I connect to the device?

There are a wide variety of sensors with analog outputs on the market, but the most common outputs are 0-10V and 4-20mA, which are supported by all our devices. Some of them are capable of measuring other less standard values. To find out more, consult the specific manual for that device.

Can I connect a sensor with PNP output to the device?

Not directly, the digital inputs of the devices are of potential-free type or NPN type. Therefore, if we want to connect a sensor with PNP output, we must use an intermediate element such as a relay to convert to NPN.

Are the device outputs PNP or NPN?

Devices that have digital outputs are of the open collector type, therefore they do not provide voltage to their output, but rather close to GND, therefore they are of the NPN type.

How many SDI-12 probes can I connect?

The SDI-12 standard can manage dozens of addresses on a single bus, but each device is limited by the available memory, CPU and power resources. For this reason, 2 probes can be connected to Mex03, 8 probes to Mex06 and 16 probes to IPex12.

What is the maximum distance I can connect an SDI-12 probe?

The standard indicates up to 60 meters, although this will always depend on the installation location and the cable used.

What is the maximum cable length you can use for analog sensor?

It depends on the section of the cable used, but if the output is by voltage, an adequate section must be guaranteed to avoid a significant drop in the cable that affects the reading. If a large distance needs to be covered (tens of meters), it is better to use a sensor with a 4-20mA output, since it avoids the problem of voltage drops in the cable and is also more immune to external interference.

I received a communication failure alert, what's happening?

Normally, and especially with wireless communication systems, there are connection drops due to the network, temporary loss of coverage, weather conditions, etc. This can cause the device to stop communicating with the platform for a few hours, but the device continues to function and record data, so as soon as it regains connection it will send all the stored information.
