Interlock a Sequence

Hello,I have a sequence for filling a condensate tank. If the condensate gets too high and causes an alarm (current code) I need to cause an interlock and shut down the sequence (new). Any ideas? I am new to interlocks and have read about these but still am stuck. Thanks in advance.

Would be good to know what software are you using

I am using RSLogix 5000. Here is my current idea. Thank you.
