Connecting sensors
Connect the supplied sensor to the gateway.
BD-sensor:
Green → A-IN1
Brown → GND
White → 3.3V
HUBA-sensor:
Green → A-IN1
White → GND
Brown → 3.3V
Activating batteries
Remove the strip to activate the batteries. Once placed, the LED next to the GPS antenna should blink briefly. If this is not the case, it means that the device has not yet been reset. In this case, remove the batteries for about two minutes to drain any remaining charge, and then put them back.
Close the case
Place the lid on the gateway and gently squeeze it shut. The foam in the lid will press against the batteries and hold them firmly in place when the unit is flipped. Tighten the 6 screws evenly. During the first assembly, the screws can be quite stiff.
Attention!
Make sure to insert the lid correctly. The foam should be over the batteries. Screwing the cover the wrong way around will damage the gateway.
Installation
The gateway can be mounted to the object to be tracked using screws, bolts, cable ties, or industrial adhesives.
Please note the following when selecting a mounting point:
Reduce the chance of accidentally crushing or detaching the device.
Increase GPS and mobile reception by mounting the gateway in a good spot.
Make sure there is sufficient ventilation.
Attention!
When the gateway is used as a battery-powered device, reception is critical to its performance.
After installation
After installing the gateway and the sensor in the tank, you should fill the tank completely. If no assets have been created for the tank in your project tank yet, do this first. You can also rename an existing one asset, should this be necessary. To visualize the newly installed tank, you need to add it to an asset group. Adjust the Tank100pct metadata and enter the 4-20mA value of a fully filled tank here.
Hint!
The tank monitor sends its data every hour, wait until you are sure that this is the highest value.
When you have changed your metadata, you can use the path tank_level, this path is percentage-wise.
Replacing Batteries
The following batteries are recommended: SAFT LSH14.
The type of battery is important. When a 4-20mA sensor is connected to the gateway, Lithium Thionyl Chloride (LTC) batteries must be used. Not all LTC batteries are built the same. Preference is given to batteries of the Spiral Type. Bobbin Type batteries may not be able to provide enough peak current. If you want to replace the batteries and open the case, make sure the silicone seal is in good condition before closing the case again.
