You can find the exact configuration of the DIP swit-
ches in the ROPEX Application Report calculated for
your particular application.
If the secondary current I
2
is less than 30A, the sec-
ondary high-current wire must be laid twice (or several
times) through the PEX-W3 or PEX-W4 current trans-
former (
ª
ROPEX Application Report).
5.11.2 Configuration of the rotary coding
switch for the temperature range
and alloy
The settings for a temperature coefficient of 780ppm
(switch position 1 and 5) are only available on control-
lers manufactured as of October 2003.
If the switch is set to "9" (as of October 2005), more
temperature ranges and alloys can be selected by
means of the ROPEX visualization software (
ª
see
section 6.10 "Diagnostic interface/visualization soft-
ware (as of October 2005)" on page 25).
