SUBJECT: New Wiring and Overloads fore MILNOR's Equipment (Why the right specs are even more important on new machine orders!)

Dear MILNOR dealer:

THE BIGGEST CHANGE IN MOTOR CONTROLS IN THE HISTORY OF MILNOR IS ABOUT TO TAKE PLACE!

For many years, MILNOR has sized components and wiring for motor starting for the lowest voltage application. this means that MILNOR machines have always had the biggest components installed in the motor control cabinet. As you can imagine, where machines were sold at higher voltages like 380 and 480, the components were often substantially bigger than necessary.

We did this to provide uniformity in control cbainets across the entire range of voltages which we produce. This also allowed any machine to be converted from one voltage to the other with a minimum number of changes in the motor control box.

NOW FOR THE BIG CHANGE!

We will not begin producing motor controls for two voltage ranges, Low voltage (200-240 volts) or high voltage (346-600 volts). This means that if the machine is ordered for 480 volts, the components will necessarily be smaller than if the machine were ordered for 240 volts. The amperage ratings on components for high voltage will be approximately half the ratings of those for low voltage -- which means smaller components will be found in high voltage control boxes.

The ramifications of this change will be found when A VOLTAGE CHANGE MUST BE MADE IN THE FIELD!

If machines are in stock and must be converted from one voltage to the other, it is possible the entire high voltage control box and motor cabling would need to be changed -- not just all of the components within the box.

In addition, spare parts now used for relatively small machines may be applicable to larger machines. For example, the overload assembly which was used on a 36026Q6P at low voltage could now be applied to a 72044 at high voltage.

Now more than ever, it is imperative that yo provide the proper specifications when ordering new equipment so that the change of voltage change is diminished in the field.

In some cases, motors had to be changed in the past on some voltage changes. However, some changes, like 480 volts to 240 volts, were usually reconnectable at the motor and only fuse and overload heaterchanges took place in the motor control box.

this new electrical scheme not requires your full understanding in the event that the voltage supply to the machine is changed.

Thank you for your continuous support.

Sincerely your.
