Version 1
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 des-
cribed 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.
6.4.1
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 deenergized.
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 to 63Hz.
3. In the case of controllers manufactured up to March 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 6.2 "Con-
troller configuration" on page 17).
4. Make sure that no START signal is present.
5. Apply the auxiliary voltage (24VDC).
6. Switch on the line voltage.
7. 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 7.11 "Diagnostic interface/visualization software (as of April 2005)" on page 33). In order to
avoid malfunctions, please check the controller configuration before continuing the startup procedure.
8. One of the following states then appears:
9. Activate the AUTOCAL function while the heatsealing band is still cold (terminals 5+14). The yellow
"AUTOCAL" LED lights up for the duration of the calibration process (approx. 10…15s). A voltage of app. 0V
appears at the same time at the actual value output (terminals 17+14). If an ATR-x is connected, it indicates
