To choose the input to use in a switches association, Amethyst III does
not take into account the state of inputs of switches with a
manual
strategy.
Example 4:
 The Disable association on severity parameter is set to Critical.
 The association is made of Switch 1 and Switch 2
 Each switch contains 2 inputs.
 Input 1 and input 4 = critical
 Input 2 and input 3 are not critical
=> the association is disabled.
=> Switch 1 selects input 2 whereas Swi
tch 2 selects input 3. An alarm
is raised.
