About REF615 Series ABB Auto Reclosing Test

I got this recloser and started reviewing some details for the required operation and I need some information about this Recloser.
1-) Its possible to test the Auto reclosing operation in the relay without injection in primary poles? In case is possible i would like to know how
2-) It's possible for the relay to sense the operation of a bypass (single pole switch) and make it trip instantaneously?
3-) The Autorecloser will only operate under a short circuit current or is sensible to underbalance too?

Thank you by hands
