It is the simple things that can cause the biggest headaches. Unfortunately, many times the simple things are forgotten or generally fall to the bottom of the priority list. To prevent downtime, however, you should not let the items we focus on in this month's issue fall by the wayside.

Shaker Maintenance

In 2005 Key Technology introduced the StrongArm™, a new spring arm that, depending on conditions, was estimated to last 20% longer than other styles. Eight years later we still have some Iso-Flo® conveyors with the original StrongArms running in factories across the globe. Spring rate consistency is the biggest factor in making the StrongArm a success in reducing maintenance cost and preventing unplanned downtime and the easily identifiable blue spring arms have even been seen on TV programs about how food products are produced.

While they may last longer than any other arm, they don’t last forever. If all other factors, such as product load, product condition, speed, etc. have not changed and you notice a change in the stroke, it is time to change the arms. Rather than adding or replacing a couple of arms, we recommend you replace all of the arms at the same time. Otherwise, you will end up in a continual maintenance routine until all the arms have been replaced.

You should refer to the drawing for your shaker to determine the original number of arms. You should also use steel setup arms (Key Technology part number: 429816.1) to ensure the bed is in the proper position when changing the arms. Refer to the Iso-Flo Technical Manual for detailed instructions, but at a minimum, place the steel setup arms on the corners; one for each corner arm bracket. For longer shakers, placing one on each side in the middle of the length of shaker will help prevent sagging and misalignment of the bed.
Setup Arm
After replacing the arms, check the speed and stroke to ensure it meets the design specifications listed on the drawing. Remember the “Max Stroke” stenciled on the side of the frame is NOT the design stroke; it is the point at which you will begin to damage the arms, the bed, or possibly the frame. To measure the speed, our technicians use a tachometer which can be ordered from our PROliance Parts Sales team (Key Technology part number: 016279).

Sorter Maintenance

Sorter Battery 
Key Technology G6 sorters use Intel Pentium and Intel Core Processor based computers. These computers use a battery to power the chips that store the hardware configuration information for the computer when the system is not powered up. Depending on conditions, these batteries (Key Technology part number: 027279) need to be replaced every 3-5 years. There are two computers that make up the processing power of the G6 system; a GUI computer and a DSP computer. We recommend that you replace both computers’ batteries at the same time. You can find the service bulletin with the replacement procedure here.
While you are doing the computer maintenance, you should check the cables to ensure all connections are tight. Also, be sure to check the gasket around the enclosure door and replace it if you see indications of water seeping through. Water intrusion and condensation are the biggest hazards to the computers and other electronics.
