The possible settings for resetting the devices via the "Reset response" parameter can be found
in the "Operation" chapters of the relevant monitoring relays.

Quitting the SET menu level will trigger an internal reset in 3UG4621/3UG4622/3UG4625 and
3UG4641 device variants and restart the startup delay.
