Parameter: Select Grp Mode
Default Setting: Edge Triggered
This setting is applicable when an assigned binary input is used to select a settings group. See Input
Config > Input Matrix > Select Group n.
When operated the active settings group can be set to 1 (Gn1), 2 (Gn2), 3 (Gn3) or 4 (Gn4). The select
group mode is defined as follows:
Level triggered: the selected settings group is operational only whilst the input is energized.
Edge triggered: the selected settings group is enabled by the leading edge of the binary input operating
pulse and remains latched in regardless of the status of the binary input.

NOTE
Only 1 group should be energized at any time. If a second group is selected simultaneously the second
selection is ignored, even if the first subsequently resets. When a level triggered selection is reset, the relay
will return to the previously active group.
