General

Q. What do the different colors signify on my stack light? 
A. Green steady light signifies the machine is running
    Green Blinking light signifies the machine is paused
    Red solid light signifies Cycle Stop
    Red Blinking light signifies the machine is faulted or an e-stop has been pressed
    Amber solid light signifies the machine is in manual mode and can be jogged
    Blue light signifies a low level condition 
 
Q. How can I obtain a copy of my PLC or HMI program?
A. Copies of the original PLC and MHI programs were included on the CD manual that shipped with your machine. Should you not be able to locate these files you may request copies from our Customer Service Dept.
 
Q. Why do I obtain a VFD fault when re-starting my machine?
A. Re-starting a machine after an E-Stop or safety interlock activation too fast can result in a VFD fault. To avoid this allow the  power to bleed off the VFDs for approx. 45 seconds prior to pressing start. An alternate solution for Allen Bradley 4M equipped machines is to set parameters A451 to 3 and A 452 to 0.
 
Q. Where can I find the settings for my machine?
A. Each machine is shipped with a Tuning Sheet placed in the electrical enclosure, the Cd manual also contains a copy of this sheet.  Should you misplace both the card copy and CD please contact our customer Service Dept. 
 
Q How can I find out if a particular container or cap will run on my machine?
A. Should you wish to run a new container or cap on your New England equipment please contact our Parts Dept. They can assist with advice if the component will run and if you would require additional change parts.

A. We recommend a lithium based lubricant for the bearings.
 
Q. How do I replace the Blue orienter wheel pads?
A. To replace the pads it will be necessary to scrape the old material off the aluminum wheel and clean the remaining residue with acetone.
      To install the new pad, apply a coat of adhesive (we recommend 3M Super 77 spray adhesive) to both  the wheel and pad.
    After allowing to dry according to the manufacturer's instructions, apply the pad working from the center out.
    It may be necessary to stretch the pad to ensure it reaches the edge of the wheel. 
 
Q. What is the recommended maintenance schedule for my Unscrambler?
