Regulator failure/defect
The current sensing
module is not connected
Incorrect phase sequence
Solution
Check or measure whether there is any
voltage between terminals L and N.
Replace the regulator or take it to repair.
Use the WATTconfig software and load the
newest firmware version or load the version
you prefer
Check whether green LED PWR is on and
the regulator is powered.
Check the USB cable connection, try using
different network cable, or try the cable
with different device (printer for example).
Check USB cable connection. When USB
device is being registered in your PC, the
yellow LED COM must flash temporarily.
Make sure the USB interface driver is
correctly installed and Windows device
manager detects it as a USB serial converter
and USB serial port.
Use the USB/COM interface driver
configuration window in WATTconfig ECO
and reset all parameters back to default
values and choose correct port.
A very few communication errors is
considered a common status and it depends
on the actual load put on the operating
system in your computer or on the
operating system running in the controller
or disturbance on communication line.
However, if there are many errors inspect
the functionality of your PC, or it may also
be a conflict at the USB interface in your PC.
Replace the regulator or take it to repair.
Connect the current sensing module
according to this manual.
Make sure that for all ILx inputs the "Phase"
field is correctly set. Perform the settings
