Device configuration
The controller must be switched off to configure the coding switch and the slide switch.
7.2.1
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 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 message is output
by the controller (
see section 8.19 "Error messages" on page 50).
For secondary currents I

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).
