1.13.15 - Night Shift Activities

Mp#21-

Screw will not retract or rotate issue.
Everything else appeared to be working correctly and the problem appeared to be a setting. Since it was still early, I called Kenny on his expertise to help me locate the problem.  We found the setting for the decomp after pressure to be too low to operate. The initial settings were 450 psi at 55%. The position for this setting was 0.10".

For unknown reasons at this time, apparently it will turn not turn the screw or retract until this pressure is set higher. When we raised it 750psi it began to operate again. We oddly found that at 100% flow volumes, it did not want to operate below 750- but when trying lower flow volumes at 50-25% it would work at pressures around 500-575- although slower in response.

So, keep in mind, anything below 500psi for this setting could create an issue? At least on this press.
