Line filter
To comply with EMC directives – corresponding to EN 50081-1 and EN 50082-2 – CIRUS 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 distur-
bances.
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 CIRUS control loops. Providing that 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.
For more technical information:
"Line filter" documentation.
It is permissible to supply several CIRUS 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 6.3 "Power supply" on page 11 must be observed.

Current transformer PEX-W4/-W5
The PEX-W4/-W5 current transformer supplied with the CIRUS
®
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 cor-
rectly (
section 6.3 "Power supply" on page 11).
