Installation

See also section 2 „Application“ on page 4.
Installation and startup may only be
performed by technically trained, skilled
persons who are familiar with the associated risks
and warranty provisions.
8.1
Installation procedure
Proceed as follows to install the RESISTRON
temperature controller RES-430:
1. Switch off the line voltage and verify that all circuits
are deenergized.
2. The supply voltage specified on the nameplate of
the RESISTRON temperature controller must be
identical to the line voltage that is present in the
plant or machine. The line frequency is
automatically detected by the temperature controller
in the range from 47Hz to 63Hz.
3. Install the motherboard in the machine frame using
the fixing screws.
4. Install the display terminal in the front panel cutout.
It is fastened by means of two clamps which snap
onto the side of the controller housing.
5. Wire the system in accordance with the instructions
in section 6 „Technical data“ on page 8, section 8.4
„Wiring diagram with relay K1 (standard)“ on
page 14 and the ROPEX Application Report. The
information provided in section 8.2 „Installation
steps“ on page 12 must be heeded additionally.
Check the tightness of all the system
connections, including the terminals for the
impulse transformer windings.
6. Make sure that the wiring conforms to the relevant
national and international installation regulations.
8.2
Installation steps
The following points should be heeded in addition to the
information provided in the ROPEX Application Report
when installing the RES-430:
Wiring/cable cross-sections:
• Use the cable cross-sections indicated in the
ROPEX Application Report. The cables between
the RES-430 motherboard and the heatsealing
band must not be longer than 1m.
• Connect the heatsealing band directly to the RES-
430. Additional clamping points can cause contact
resistances, leading to temperature control errors.
The connecting cables between the
motherboard and the heatsealing band must
not be laid through closed steel sheets or pipes, in
order to avoid temperature control errors. The
permissible pipe and sheet materials are aluminum
and plastic.
Impulse transformer:
• Specification as indicated in the ROPEX Application
Report.
Heatsealing band/sealing bar:
• Use a heatsealing band with a suitable (positive)
temperature coefficient.
• Copper the ends of the heatsealing band to prevent
them from overheating.
• Push-on connectors on the sealing bar can lead to
loose contacts. Use cables with screw connections.
