RES-407
Version 1
The electrically isolated analog interfaces for the temperature set point and the actual temperature (0-10VDC)
allow the temperature to be set either directly on the machine PLC or by means of an external potentiometer
(PD-x).
Similarly, the real heatsealing band temperature can be visualized either on the display of the machine PLC or on
an external temperature meter (ATR-x).
The RESISTRON
®
temperature controller RES-407 features an integrated fault diagnosis function, which tests
both the external system (heatsealing band, wiring etc.) and the internal electronics and outputs a selective error
message in case of a fault.
To increase operational safety and interference immunity, all 24VDC logic signals are electrically isolated from the
controller and the heating circuit.
Coding switches on the temperature controller itself can be used to adapt to different heatsealing band alloys
(Alloy A20, LEX3500 etc.) and set the required temperature range (0...300°C, 0...500°C etc.) on all controllers
manufactured as of June 2003.
An external 24VDC auxiliary voltage is required to supply the isolating amplifiers and optocouplers. The compact
design of the RESISTRON
®
temperature controller RES-407 and the plug-in connections make this controller
easy to install.

Installation
See also section 1 "General information" on page 3.
Installation and startup may only be performed by technically trained, skilled persons who are
familiar with the associated risks and warranty provisions.
5.1
Installation procedure
Proceed as follows to install the RESISTRON
®
temperature controller RES-407:
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 RESISTRON
®
temperature controller in the electrical cabinet on a standard top hat rail (DIN TS35
rail, according to DIN EN 50022). If several controllers are installed on one top hat rail, the minimum clearance
specified in section 9 "Technical data" on page 42 must be allowed between them.
4. Wire the system in accordance with the instructions in section 5.3 "Power supply" on page 10, section 5.6 "Aux-
iliary voltage" on page 13 and the ROPEX Application Report. The information provided in section 5.2 "Instal-
lation steps" on page 9 must be heeded additionally.
Check the tightness of all the system connections, including the terminals for the impulse trans-
former windings.
5. Make sure that the wiring conforms to the relevant national and international installation regulations.
