Description of the controller
The microprocessor technology endows the RES-430 RESISTRON temperature controller with previously unat-
tainable capabilities:
• Very simple operation thanks to AUTOCAL, the automatic zero calibration function.
• Good dynamic response of the control system thanks to AUTOTUNE, which adapts automatically to the con-
trolled system.
• High precision thanks to further improved control accuracy and linearization of the heatsealing band character-
istic.
• High flexibility: Secondary voltage range from 12V to 42V, current range from 20A to 90A.
• Automatic adjustment to the line frequency in the range from 47Hz to 63Hz.
• Increased protection against dangerous conditions, such as overheating of the heatsealing band.
A time control (timer) function integrated in the controller enables the complete heatsealing process to be con-
trolled on simple machines, such as table heatsealing tools. A configurable relay output can be used to drive
motors, energize magnets etc.
The process data is represented on an LC display with 4 lines and 20 characters. Various display languages can
be selected.
The real heatsealing band temperature is visualized on the display both as a digital number in °C and in the form
of a dynamic bar.
In addition to the digital and bar indications on the display, the ACTUAL temperature of the heatsealing band is
supplied to an analog 0…10VDC output. The real heatsealing band temperature can thus be visualized on an
external temperature meter (e.g. ATR-x).
The RESISTRON temperature controller RES-430 also 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.
The menu in 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.).
The RESISTRON temperature controller RES-430 consists of two components: a motherboard with a power sec-
tion for installation in the machine frame and a separate display terminal. The compact design and the plug-in con-
nections make this controller easy to install.
