There are a number of areas to setup before using downtimes as follows
Settings > Settings > Functionality - Ensure "Downtime register" is tuned on
Settings > Downtimes > Categories - Setup downtime groups to help analyse for example - Failures, Planned, Material outage etc
For a user to Insert or Edit / Delete they must have the privileges - This can be setup from Settings > Users > User Groups - Select the User group - Then Downtimes.
You can then set Insert and edit / delete seperately as needed for that User Group.
