7.4.4. PrioritysourceconnectedonswitchIorII(M-GApplication)
Certain applications or installation constraints may require that the main supply is connected to switch II instead of
switch I. This is possible to cater for with certain precautions.
The ATyS p includes the facility to adapt the switch priority supply using the configuration in the software that will swap
the main supply and switch logic (S1 = SW2 in SETUP Menu). When this is done pay attention to the LED switch
position display that will no longer correspond to the identification labels on the switch. The LED's will correspond to
the switch that is energized however the main supply will be displayed under II. In this case it is important to update
the ATS controller sticker so as to correspond with the actual wiring and configuration.
