Using a data table to replace time values with points values.

Hi
I need a formula that will insert a points value into a cell when a time value has been input in another cell.
Production workers log their time spent using up to 5 different machines in a working day and I have to calculate their exposure points.
On the attached spreadsheet I have a data table for the values and a timesheet for a worker.
The values that are showing in the ELV(400pts max) row are manually calculated from the data table, where multiple time values are input, the points are cumulative and this is where I need your help please.
Can anyone please write me a formula that will do this?

Your help and advice will be much appreciated.
