Line filter
To comply with EMC directives – corresponding to
EN 50081-1 and EN 50082-2 – RESISTRON control
loops must be operated with line filters.
These filters damp the reaction of the phase-angle
control on the line and protect the controller against line
disturbances.
The use of a suitable line filter is part of the
standards conformity and a prerequisite of
the CE mark.
ROPEX line filters are specially optimized for use in
RESISTRON control loops. Providing they are installed
and wired correctly, they guarantee compliance with
the EMC limit values.
You can find the exact specification of the line filter in
the ROPEX Application Report calculated for your
particular heatsealing application.

"Line filter"
documentation.
It is permissible to supply several
RESISTRON control loops with a single line
filter, providing the total current does not exceed
the maximum current of the filter.
The wiring instructions contained in section 8.3 "Power
supply" on page 14 must be observed.

Current transformer PEX-W2
The PEX-W2 current transformer supplied with the
RESISTRON temperature controller is an integral part
of the control system. The current transformer may only
be operated if it is connected to the temperature
controller correctly (
