I was just asked…
“What is the value of having a minimum screw recovery alarm? I can see the maximum happening but the minimum I’m not so sure. I guess if someone puts the screw speed up to purge and does not put it back it may be useful. Is there anything else I might be missing?“
I believe you are correct Jim. Sometimes companies put alarms and options on the machine just because it’s easy to program.
The only benefit to such an alarm may be to monitor tampering of screw RPM but this is extremely rare.
