Overriding chuck pressure alarm on LB15 and/or ES-L6 lathes

[aaroncswenson]

I am trying to find out if there is a way to override the alarms I get on our LB15 and ES-L6 lathes when the chuck pressure is turned down too low (approx below 100PSI). We have an Okuma Cadet that can be turned down to 0PSI without alarming out and I don't know how it was made to do so! I have some very thin wall tubing parts to make and would not like to crush them! Any info would be GREATLY appreciated.
Alarms are as follows:
LB-15 w/ OSP5000L-G: 117 Alarm A Chuck Clamp 100
ES-L6 w/ OSPU10-L: 1707 Alarm-A Hydraulic oil pressure low 1

The cadet should have the alarm. It's a mechanical adjustment on the chuck pressure switch. The kitigawa chucks are dangerous below 75 psi or so. They are not a counter centrifugal chuck, so the rotating mass of the jaws can open them at low pressure. A collet chuck is a different story. Both the lb15 and esl use a different switch, just need to look for them and use the screwdriver/Allen wrench and set them lower.

normal solution would be to prepare good collet (just an accurate tube) and chuck the workpiece through this collet. It works great.
