Controller configuration
The controller must be switched off in order to configure the coding switches and plug-in jumpers.
10.2.1 Configuration for secondary voltage and current
Automatic configuration (AUTORANGE)
(as of June 2006)
The secondary voltage and current ranges are automatically configured by the automatic calibration function
(AUTOCAL). The voltage is configured in the range from 0.4VAC to 120VAC and the current in the range from
30A to 500A. If the voltage and/or current are outside the permissible range, a detailed error message appears
on the controller (
see section 11.21 "Error messages" on page 52).
Configuration with coding switches
(up to May 2006)
Set the DIP switches for matching the secondary voltage U
2
and the secondary current I
2
to the correct position
for
your
application.
You can find the exact configuration of the DIP switches in the ROPEX Application Report calculated
for your particular application.
If the secondary current I
2
is less than 30A, the secondary high-current wire must be laid twice (or several times)
through the PEX-W2 or PEX-W3 current transformer (
ROPEX Application Report).
