1. MY THREE-PHASE LOAD DOES NOT SEEM TO HAVE ENOUGH POWER TO START.
•
Check to make sure your converter is turned on .
•
Check to make sure your converter is big enough . If not, a second converter of equal size can be installed
in parallel to your converter to double its size . Ask us about our Autolink .
•
Make sure your wire is big enough . Go up at least one size for every 50 feet of run . Wire may need to be
upsized for hard loads .
•
You may need a larger single-phase service . Everything may be big enough on your end, but sometimes
the power company's transformer is not big enough to handle the full load plus other loads on your grid .
Call your power company or electrician for service .
2. MY MACHINE DOES NOT START WHEN I TURN ON THE CONVERTER.
•
The Start/Stop buttons on the converter are designed to only start your converter and not your loads
converter . If your load does not have its own motor starter, American Rotary has a full line of motor
starters available .
3. MY MACHINE STARTS RIGHT AWAY WHEN I TURN ON MY CONVERTER.
•
Make sure your machine has its own Start/Stop button to ensure the converter is running before the load
is turned on . If your machine does not have its own start/stop button please contact American Rotary .
4. A CAPACITOR FAILED OR IS LEAKING.
•
A start capacitor may fail as a result of too frequent starts or having a load on when starting . Make sure all
loads are disconnected when starting, including transformers .
•
An overload such as too heavy of a load for the converter can cause the start and run capacitors to fail .
•
A power surge such as a lightning strike or a brown-out can cause the capacitors to fail . A surge
suppressor may be needed and can be found on the American Rotary website or by calling its sales office .
5. THE IDLER IS VERY HOT.
•
The Baldor idlers are rated up to 150° C . It may be normal for them to run hot . High current on one or more
lines may also cause them to run hot . A good voltage balance means a good current balance .
6. MY THREE-PHASE LOAD HAS CONTACTORS THAT ARE CLICKING, LIGHTS THAT ARE FLICKERING OR IT KICKS OUT AS SOON AS IT
STARTS.
•
All controls should be run from T1 and T2 (the single-phase lines) . These lines do not fluctuate voltage
as much as T1 to T3 or T2 to T3 . If your machine does not have these clearly marked, try different
combinations of T1, T2 and T3 .
7. MY VOLTAGE IS TOO HIGH OR TOO LOW.
•
The voltage that the phase converter will produce is based off the incoming single-phase voltage . The
phase converter will use your voltage measured leg to leg on single phase as a baseline for balancing
the voltage . Leg to leg voltage may vary by about 5% while under load . The phase converter does not
transform the voltage up or down . If you need to raise of lower your voltage, a transformer may need to be
added . Please contact American Rotary for assistance .
