Power supply
Refer to the information in the “Power supply” section
of the documentation for your temperature controller.
The RESISTRON monitoring device and the
temperature controller must both be con-
nected to the same phases of the power supply. If
not, they may no longer work correctly.
The RESISTRON monitoring device must be operated
with an LF-xx480 line filter. It can either be equipped
with a separate line filter or share the same filter as the
temperature controller.

Unit configuration
The possible unit configurations are explained in the
following sections. Proceed as described in
section 8.4.1 "Initial startup" on page 20 to start up the
unit for the first time.
8.2.1
Configuration of the secondary
voltage and current ranges
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 of the permissible range, a detailed error
message appears on the RESISTRON monitoring
device (
section 9.18 "Error messages" on page 37).
If the secondary current I

is less than 30A, the wire
must be laid twice through the PEX-W2 or PEX-W3
current transformer (
ROPEX Application Report).
