AMU Installation

33. Drag a data from that list and drop into the related company’s motor on the left so that
the data can be assigned to a specific motor and a report is opened.
34. If you do not assign a waveform, you can assign it by selecting a report on the left and
clicking ‘Assign Waveform File’ button.
35. A report can be viewed by double-clicking on it. The report will appear on the right
pane.
36. A report can be exported as pdf file, e-mailed as attachment or previewed to print using
the ‘Export’, ‘E-Mail’, and ‘Preview and Print’ buttons on the ribbon bar, respectively.
37. The PSD and waveform graphs of a report can be viewed by clicking ‘PSD’ and ‘VI
Waveform’ tabs, respectively.
When data acquisition is done
1. Ensure that motor is not running.
2. Turn voltage, AMU, and power fuses off in order.
3. Remove current transformers.
4. Disconnect power, voltage and current cables.
2.6. Applying power to the AMU unit
Once the motor connections have been made, power should be applied to the unit. AMU
requires between 100 and 240VAC obtained from a single phase, neutral and ground. At
this stage, the Power indicator at the left of the front panel will light. If this does not occur,
please check that the correct voltages have been applied.
Immediately on application of power, the LED condition indicators should briefly flash and
activity should be seen on the main display. The text "Initializing" followed by a series of
dots will appear.
"Initializing....."
After a few seconds, the display should indicate that it is in the IDLE mode. AMU is now
ready for use. When using a device for the first time the message "Bad flash data! Press
Clear" may be displayed. In this case press the CLEAR button several times until the
message disappears.
2.7. Installing with soft-starter systems
AMU can be installed with standard soft-starter systems provided that they are
automatically bypassed immediately after motor start-up and during subsequent use. Un-
bypassed, soft-starter systems can introduce considerable distortion into the current
waveforms and thus prevent AMU from modeling the properties of the motor itself. If AMU
