Tele TSX17

[briancr]

I have an old Tele TSX17 PLC that has gone legs up on me. I am in the process of upgrading to a SLC500 (purely digital I/O). Luckily I do have a hard copy of the ladder logic so it will not be to difficult to reprogram the SLC500. The problem is that I have come across a timer that I do not know much about. See attached pdf.
In label 47, T11 has an extra output R which I am not sure what it does?
Any assistance will be appreciated

Thanks
Brian

The 'R' output will be active while the timer is running (and de-activate again when 'Done')
