17. Cause & Effect Programming
For more complex applications, it is often a requirement to control plant in the event of Water Leak situations to
assist with shutdown of equipment or the water supply.
Because the Hydrosense ID system has inherent flexibility, this is simple to achieve by applying Cause & Effects
to Inputs and Outputs anywhere on the system.
Cause & Effects can be started or acted upon by any part of the system not just the detection loop or control
panel but by both of these and by the additional I/O modules too.
With careful planning, this can save costs on installation by reduced wiring runs and can be changed at any time
to suit changes in requirements.
Cause & Effects programming requires the Loop Explorer PC (LE2) configuration utility (which will run on a
Windows compatible computer) and a download lead to transfer the data to the control panels.
Using Cause & Effect programming it is possible to combine Inputs or Zones using logical operators, to operate
on Outputs in any manner desired.
It should be noted here however that when using Zonal Cause & Effects the system will act upon Water Leak
Inputs in the zone of activation only. Inputs in the selected zone that are not configured as Water leak event type
will not contribute to a Zonal Cause & Effect.
Cause & Effects can also be used to disable any Outputs or groups of Outputs in response to the chosen Input
conditions. This is particularly useful where normal operation of the Water Leak system requires regular
intervention by the end user as switches can be provided anywhere on the system to allow isolations to be
performed without operating the control panel.
Also to assist the end user and encourage regular testing, a special "Test Mode" Cause & Effect facility is included
which allows specific parts of the system to be tested without operating sounders or shutting down plant etc. This
would normally have to be done by disabling individual outputs at the control panel with the risk of missing
something and shutting down an important plant or process.
Full details of Cause & Effect programming are included within the Loop Explorer PC (LE2) configuration utility,
which also allows full system configurations to be created and downloaded to individual control panels using a
simple graphical user interface.
The Loop Explorer PC (LE2) configuration utility contains comprehensive, context sensitive help files and example
applications.
NOTE
– When configuring the system using Cause & Effects, care should be taken to ensure that the system
operation conforms to the local regulation requirements.
