Page 27: Description Of Trap Message
3.4.3 Description of TRAP message Messages of TRAP type are used for immediate transmitting of information about event detected by the NB-K430 module. The information contains type of detected event (e.g. ”Processor temperature exceeded limit”) that can be followed by one or several variables with parameters of the event (e.g. ”Temperature” and ”Temperature limit”). -
Page 28: Encryption Of Messages
Type of detected event is encoded into the ”Alarm code” variable (OID 60 - TRAP CODE), where value of variable determines event type. Current version of the NB-K430 module supports sending of one type of event - information about the module reset, with additional information about its cause. -
Page 29: Operational Conditions
Operational conditions This section of the document describes basic recommendations for transportation, storing, installation and operation of NB-K430 radio modules. General Operation Risks The radio modules are electronic devices power-supplied by internal batteries. The modules read counters or registers of the connected consumption meters. -
Page 30: The Condition Of Modules On Delivery
As NB-IoT services are charged by GSM operator, it is recommended to insert SIM and activate the service just before module installation. Safety precautions Warning! Mechanical and electrical installation of the NB-K430 module can be provided only by a person with necessary qualification in electrical engineering. Environmental protection and recycling The equipment contains non-rechargeable lithium battery. -

4.10 Operation of the NB-K430 module The NB-K430 module performs readings of watermeters and broadcasting of radio messages fully automatically. The greatest risks of permanent breakdown of module broadcasting are commonly caused by human activities within the installation site, especially mechanical damage of the module, excessive humidity or water inundation, or shading the RF signal by metallic object due to building operations. -
Page 34: Troubleshooting
The risk of premature battery discharge could be eliminated by respecting the instructions described in para- graph 4.1.2. Troubleshooting Possible causes of module failures If during operation of NB-K430 module some anomaly, malfunctions or other troubles are recognized, the possible causes of the failures can be classified by following categories: 5.1.1 Power supplying failures The module is supplied by electrical power from the long-life internal battery. -
Page 35: Power Supplying Failures
To identify a reason of device failure or any anomaly in its operation follow this procedure: 1. No data are available from any watermeter read by the NB-K430 module. In this case it is recommended to check functionality of the module subsystems in following order: check correctness of setting of the module in the central system database;... -
