7. One of the following states then appears:
8. Set the controller configuration as described in
Kap. 9.3 „Controller configuration“ auf Seite 18. The
following settings are always required:
9. Activate the AUTOCAL function while the
heatsealing band is still cold (with step 7 in the
Settings menu or by means of the "AUTOCAL"
signal, terminals 20+25). The progress of the
calibration process is indicated by a counter on the
display (approx. 10…15s). A voltage of 0VDC
appears at the same time at the actual value output
(terminals 20+24). If an ATR-x is connected, it
indicates 0°C.
When the zero point has been calibrated, the
display is reset to the home position and 20°C is
indicated as the actual value. A voltage of 0.66VDC
(for the 300°C range) or 0.4VDC (for the 500°C
range, equivalent to 20°C, appears at the actual
value output. If an ATR-x is connected, it must be set
to "Z" (20°C).
If the zero has not been calibrated successfully, an
alarm signal indicates error codes 104…106, 211.
In this case the controller configuration is incorrect
(

and ROPEX Application Report). Repeat the zero
point calibration after the controller has been
configured correctly.
10.When the zero point has been calibrated
successfully, the main menu appears on the display
again. Then specify a defined temperature
(heatsealing temperature) with step 1 in the
Settings menu (or apply a 0…10VDC voltage to the
analog input, terminals 20+23) and activate the
"START" signal (HEAT). Alternatively, a heatsealing
process can be started by pressing the "HAND" key
(display in home position). The indication of the
ACTUAL temperature on the display (digital value
and dynamic bar) permits the heating and control
process to be monitored.
The controller is functioning correctly if the
temperature indicated on the display has a
continuous curve, in other words it must not jump
abruptly, fluctuate or deviate temporarily in the
wrong direction. This kind of behavior would indicate
that the U
R
measuring wire has been laid incorrectly.
If an error code is displayed, please proceed as
described in Kap. 10.21 „Error messages“ auf
Seite 49.
If the heatsealing temperature is selected via
the analog input at terminals 20+23, the
specified voltage value must be checked with a
voltmeter before the heatsealing process begins, in
order to prevent incorrect settings or excessively
high heatsealing temperatures.
11.Burn in the heatsealing band (

AUTOCAL function.
9.5.2
Restart after replacing the
heatsealing band
To replace the heatsealing band, proceed as described
in Kap. 9.4 „Heatsealing band“ auf Seite 20.
Always use a heatsealing band with the
correct alloy, dimensions and copper-plating
in order to avoid malfunctions and overheating.
Continue with section 9.5.1, steps 9 and 10.
