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 "Safety and warning
notes" on page 3 and section 2 "Application" on
page 4.
Installation and startup may only be
performed by technically trained, skilled
persons who are familiar with the associated risks
and warranty provisions.
9.4.1
Initial startup
Prerequisites: The controller must be correctly installed
and connected (
ª
section 8 "Installation" on page 12).
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 9.2 "Controller configuration" on
page 19).
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 indicate 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 (
ª
ª
ª
ª
section 10.11 "Diagnostic interface/
visualization software (as of April 2005)" on
page 31). 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 0…3°C.
When the zero point has been calibrated, the
"AUTOCAL" LED goes out and a voltage of 0.66V
(300°C range) or 0.4V (500°C range) appears at
the actual value output instead. If an ATR-x is
connected, it must be set to "Z".
If the zero point has not been calibrated
successfully, the red "ALARM" LED blinks slowly
(1Hz). In this case the controller configuration is
incorrect (
ª
section 9.2 "Controller configuration"
on page 19 and ROPEX Application Report).
Repeat the calibration after the controller has been
configured correctly.
10.When the zero point has been calibrated
successfully, set a defined temperature at the set
point input (terminal 16) and apply the "START"
signal (HEAT). The "HEAT" LED then lights up. The
heating and control process can be observed at the
actual value output:
The controller is functioning correctly if the
temperature (which corresponds to the signal
change at the analog output) follows a harmonious
