Immediately after the WiFi settings, below the page, there are the MQTT ones. Works with 4 AA batteries (1.5V, alkaline or Lithium - for outdoor winter use you need to use AA lithium batteries because the alkaline ones suffer from the cold); on request it is also available for working with external 5V power supply. This can be used to start the engine or supply external equipment able to start the generator. Before connecting the DC supply connect in series a fuse of a suitable size to protect the cables from short circuits. The RS485 system used for Modbus communication provides a main cable (Bus or backbone), to which all the devices have to be connected with branches (also known as stubs) that are as short as possible. Send the configuration SMS to the MODEM: The system will be functional in 2 minutes. For example, you can set to start the engine every 10 days for 5 minutes. In order to increase the extent of the Modbus network, repeaters can be used; and signal amplifying and regenerating devices provided with two communication ports that transfer to each what they receive from the other.

Two fully configurable relays can be used for various special functions as described in the "PROGRAMMABLE OUTPUT" section of the user manual. Connect your generator as indicated in the Be1 recommended wiring diagram section 17 of the Be1 installation manual. The panel consists of basic ingredients: a Be1 generator controller, a general-purpose interface relay board, a state-of-art GSM Be148-1 gateway and a multiband MODEM. Basically, therefore, they can be used with RXTXeasy GSM or DisplayRX or ControlHUB.. TXsoil is a compact and low consumption sensor that can measure and transmit the humidity of the ground WiFi or RF or GSM. TXSoil can transmit the humidity to a Web server or to a VisualVision's display / concentrator such as DisplayRX or ControlHUB or RXTXeasy GSM - with adjustable interval, remaining for the rest of the time in standby with very low consumption. If on the other hand each terminal can accept only a single cable, a proper branch must be created using three auxiliary terminals for each instrument to be connected. In this case it is possible to connect the main inlet and outlet terminal directly to the terminals of an instrument without creating a branch. The Be1 is capable of monitoring generators up to 500V. It can measure the frequency of the alternating voltage but you can add a pickup in case you have machinery without the alternator.

In case of a GSM issue, failure of the antenna, or SIM card, the Be1-GSM panels turn on a red alarm light. Failure to stay within this range will result in, at best, signal corruption, and, at worst, damage to connected devices. 12 V, i.e. ±7 V on top of the 0-5 V signal range. Grounds between buildings may vary by a small voltage, but with very low impedance and hence the possibility of catastrophic currents - enough to melt signal cables, PCB traces, and transceiver devices. The cabling of the industrial communication systems (Modbus RS485) is different in some ways from the cabling used for power cabling and the electrician may experience some difficulties if he is not an expert in Modbus communication networks. Thanks to the flexibility of the Be1 generator controller you may connect any style of engine. Be1 features adjustable settings for pre-glow and gas-purge solenoid. The protection cover is made in LEXAN and features a 3M 467 high-performance adhesive.

The box is made of polycarbonate offering IP56 protection. The product is sent in a shockproof box. 2) right under WiFi settings, instead of WiFi TX to Hub / DisplayRX / RXeasy, choose the other settings and write your server / script URL. In the WiFi settings (as in the figure above illustrating B), choose "WiFi MQTT". You will need to connect to a WiFi (home, work, laboratory, etc.) through which an MQTT Broker or the Internet is available. You can enter the data relating to the MQTT Broker you want to use; the name of the Topic to be used to control it and to read the periodic transmissions of the humidity percentage is shown. Loose the two screws on the left side in a way that the door of the panel can pivot toward the left side. This way, the lines will be biased to known voltages and nodes will not interpret the noise from undriven lines as actual data; without biasing resistors, the data lines float in such a way that electrical noise sensitivity is greatest when all device stations are silent or unpowered. The two values provide a sufficient margin for a reliable data transmission even under severe signal degradation across the cable and connectors.
