H5D-60 - How to set re-focusing on Interval Shots?

[whatsoever]

I am new to the Hasselblad System. I recently brought a 2nd-hand H5D-60. When I try to take the interval shots, I spotted than the lens does not perform re-focusing after the 1st shot. Could anyone give me an advice in how to make the lens to re-focus between shots?
