” Module usage The WB169-SI2 module can be used either for remote reading of two consumption meters with pulse output, or for transfer of alarm messages from two two-state sensors. It is possible to combine both type of usage. When using for remote reading of consumption meters (water meters, gas-meters, electro-meters...), up to two meters with standard pulse (”SI”) output can be connected to the module.

By setting of ”2” value the pulses are directed to the ”t1” counter ” during ”0” ( low”, closed contact) status of control voltage (see figure). As only the second port of the WB169-SI2 ” module can be used for tariff switching, the ”trf” command should be always entered with index ”1”.

Operational conditions This section of the document describes basic recommendations for transportation, storing, installation and operation of WB169-SI2 radio modules. 4.0.1 Risk of mechanical and/or electric damage The devices are enclosed in plastic boxes, so that the electrical components are protected from the direct damage by human touch, tools or static electricity.
(with exception of modules with additional sealing by silicon filling - see paragraph 4.1). Safety precautions Warning! Mechanical and electrical installation of the WB169-SI2 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.

Using of WB169-SI2 module for remote monitoring of sensors The WB169-SI2 module can be used also for remote monitoring of any two-state sensors with either isolated contact (e.g. mechanical contact, relay, reed contact...), or solid-state relay, or open collector types of outputs. It is not possible to connect a sensor with its own source of voltage on its output.
Figure 21: Types of sensor outputs convenient for WB169-SI2 module Setting of sensor input is described in detail in paragraph 3.1.9 Setting of sensor inputs”. Before setting it is ” necessary to realize, in which state the sensor output is switched off, and in which state it is switched on, and which status should be propagated as alarm message”.
Troubleshooting Possible causes of module failures If during operation of WB169-SI2 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. Approximate battery life is specified in paragraph Modul usage”.
In case of unstable data transfer from connected sensors the signs of failure are very similar to the troubles with pulse meters - the wrong indication of measured data from sensors. Troubleshooting of this failure is similar with troubleshooting of pulse meters: 1. visually check the sensor and connecting cable between sensor and radio-module for any damage; WB169-SI2...
To identify a reason of device failure or any anomaly in its operation follow this procedure: 1. No data are available from all meters/sensors connected to the WB169-SI2 module. In this case it is recom- mended to check functionality of the module subsystems in following order: check functionality of power supplying as described in the paragraph 5.1.1...
