    record information about the module installation (serial number, position, picture of installation...) to the operational documentation under internal rules. When locating installation site, selecting antenna type and antenna position it is necessary to take into account con- ditions for radio signal propagation in the area of installation. The conditions is possible either estimate empirically on the base of previous experience, or accomplish a measurement of the signal strength by the signal analyzer.

  • Page 29: Troubleshooting

    The greatest risks of permanent breakdown of module RF communication (or communication breakdown of local wired bus) are commonly caused by human activities within the installation site. It is mainly about the following risks: turning off the module power (e.g. circuit breaker failure or unintentional shutdown); temporary or permanent shading of the antenna (e.g.
