Vacuum switch and vacuum break
valve, etc. are unitized, so types
matching the work purpose is
selectable.
Types with analog output, 2-point
switch output, and inexpensive
analog output are available for
vacuum switch specifications.

Page 6: Safety Precautions
Series Safety precautions / How to use Safety precautions Refer to Intro 13 for the general precautions of the vacuum system components. CAUTION Monitor if piping resistance or required vacuum release flow is large. Insufficient vacuum release flow could cause problems. Check specifications before use. How to use 1. - Page 7 Series How to use 3. Adjustment method of break valve Adjustment method of break air Turning the vacuum release air adjustment needle to right (CW) decreases the release air flow and turning it to left (CCW) increases it. Flow: small Flow: large * After adjusting vacuum release air, tighten the lock nut so that the setting does not change.
