Controller features
The analogue interfaces for temperature setpoint and temperature actual value 0…10 VDC, which are electrically
isolated from the heating circuit, permit temperature setting directly from the machine control or also through an
external potentiometer (PD-x).
The real heating element temperature can also be visualised on a machine controller display or an external display
instrument (ATR-x).
The RESISTRON
®
temperature controller RES-5007 has an integrated error diagnosis that checks both the
external system (heating element, wiring, etc.) and the internal electronics and puts out a differentiated error mes-
sage in case of malfunction.
To increase operational security and immunity to interference, all 24VDC logic signals and 0-10VDC analogue
signals are electrically isolated from the heating circuit.
Adjustment for different heating element alloys (alloy A20, etc.) and setting of the temperature range to be used
(0…300°C, 0…500°C, etc.) can be performed through coding switches on the temperature controller itself.
An external voltage supply of 24VDC is required for the controller. The compact design of the RESISTRON
®
tem-
perature controller RES-5007 as well as the plug-in connecting terminals make mounting and installation easier.
An overview of the most important features and functions:
• Easy calibration of the heating element through AUTOCAL, the automatic zero-point setting
• High control dynamics through AUTOTUNE, automatic adjustment to the controlled system
• High flexibility: A secondary voltage range of 0.4V to 120V and a current range of 30A to 500A are covered
through the AUTORANGE function
• Automatic adjustment to the network frequency in the range of 47 Hz to 63 Hz
• Wide voltage range for flexible use from 110 VAC to 415 VAC
• Easy and convenient system diagnosis and process visualisation through the free, downloadable software
ROPEXvisual®
• Error diagnosis

Mounting and Installation
See also section 2 "General information" on page 3.
Mounting, installation and commissioning may only be performed by qualified and trained persons
who are familiar with the related hazards and warranty stipulations.
The supply voltage to the machine side must lie within the permitted voltage and frequency range
of the RESISTRON
®
temperature controller. Otherwise, there is the danger of a defect.
6.1
Installation sequence
Proceed as follows during mounting and installation of the RESISTRON
®
temperature controller RES-5007:
1. Switch off network voltage; verify that no voltage is present.
2. Mounting of the RESISTRON
®
temperature controller in the switching cabinet on a TS35 top hat rail (in accord-
ance with DIN EN 50022). If several devices are mounted, the minimum distance specified in section 10 "Tech-
nical data" on page 35 must be maintained.
3. Wiring of the system in accordance with the regulations in section 6.3 "Power supply" on page 10, section 6.6
"Supply voltage" on page 13 and the ROPEX Application Report. The specifications in section 6.2 "Installation
notes" on page 9 must also be observed.
