5.12.2 Replacing the heatsealing band
All power supply leads must be disconnected from the RESISTRON
®
temperature controller in order
to replace the heatsealing band.
The heatsealing band must be replaced in accordance with the instructions provided by the manu-
facturer.
Each time the heatsealing band is replaced, the zero point must be calibrated with the AUTOCAL function while
the band is still cold, in order to compensate production-related resistance tolerances. The burn-in procedure
described above should be performed for all new heatsealing bands.

Startup procedure
Please also refer to section 1 "General information" on page 3 and section 2 "Application" on page 7.
Installation and startup may only be performed by technically trained, skilled persons who are
familiar with the associated risks and warranty provisions.
5.13.1 Initial startup
Prerequisites: The controller must be correctly installed and connected (
section 5 "Installation" on page 8).
Proceed as follows to start up the controller for the first time:
1. Switch off the line voltage and verify that all circuits are de-energized.
2. The supply voltage specified on the nameplate of the 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 47…63Hz.
3. In the case of controllers manufactured up to September 2005, the settings of the DIP switches on the controller
are indicated in the ROPEX Application Report and depend on the heatsealing band that is used (section 5.11
"Controller configuration" on page 16).
4. Make sure that no START signal is activated.
5. Switch on the line voltage.
6. When the voltage is switched on, the yellow "AUTOCAL" LED lights up for approximately 0.3 seconds to indi-
cate that the controller is being powered up correctly.
As of SW-Revision 106:
If the red "ALARM" LED lights up for 0.3s in addition to the yellow "AUTOCAL" LED when the
voltage is switched on, the configuration of this controller has been changed in the visualization software
(
section 6.10 "Diagnostic interface/visualization software (as of October 2005)" on page 32). In order to
avoid malfunctions, please check the controller configuration before continuing the startup procedure.
