problem.
3. You should use separate outputs to indicate “comms OK” of different remote modules.
4. It is recommended that you set the reset time at #1 to more than twice the update time of the
mapping at #2. This means that the comms OK output will only reset if #1 misses two consecutive
updates from #2.
3.2.6 Testing and Commissioning
We recommend that you set-up and test the system with all of the modules together before you install
the modules. It is much easier to find a configuration problem.
When the system is configured, record the radio signal strength and background noise level for each
radio link. If there are future communications problems, you can compare the present measurements to
the as-commissioned values. This is an effective way of finding problems with antennas, cables and
also changes in the radio path (for example, the erection of new buildings).
