8.2.1
Configuration of the ranges for secondary voltage and current
The ranges for secondary voltage and current are configured automatically when automatic calibration
(AUTOCAL) is carried out. Configuration takes place in the voltage range of 0.4 VAC up to 120 VAC and
in the current range from 30 A to 500 A. If voltage and/or current is outside the allowed range, a detailed error mes-
sage is output by the regulator (
section 9.25 "Error messages" on page 48).
For secondary currents I
2
less than 30 A, the secondary high-current line must be guided 2 times (or several times)
through the transformer PEX-W4 or PEX-W5 (
ROPEX application report).
8.2.2
Configuration of the rotary coding switch for temperature range and alloy
When the switch position “9” is selected, additional temperature ranges and alloys can be set through the ROPEX
visualisation software (
section 9.22 "USB-interface for visualisation software ROPEXvisual
