9. Activate the AUTOCAL function while the heatsealing band is still cold (with step 107 in the Settings menu).
The progress of the calibration process is indicated by a counter on the display (approx. 10…15 s). A voltage
of 0VDC appears at the same time at the actual value output (terminals 10+11). 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 the previously set
AUTOCAL temperature is indicated (default: 20°C). A voltage of 0.66VDC (200°C and 300°C ranges) or
0.4VDC (400°C and 500°C ranges) appears at the actual value output at 20°C. If an ATR-x is connected, it
must be set to "Z" (20°C).
If the zero has not been calibrated successfully, an error message indicates error codes 111, 114, 211. In this
case the controller configuration is incorrect (
section 9.2 "General controller configuration" on page 21 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 101 in the Settings menu and activate the
"START" signal (HEAT). Alternatively, you can start a heatsealing process by pressing the "HAND" key
(assuming step 213 has not been locked in the Configuration menu and the display is in the 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).
If an error code is displayed, please proceed as described in section 10.21 "Error messages" on page 60.
11.Burn in the heatsealing band (
section 9.6 "Heatsealing band" on page 35) and repeat the AUTOCAL func-
tion.
9.7.2
Restart after replacing the heatsealing band
To replace the heatsealing band, proceed as described in section 9.6 "Heatsealing band" on page 35.
Always use a heatsealing band with the correct alloy, dimensions and copper-plating in order to
avoid malfunctions and overheating.
Continue with section 9.7.1, steps 9 and 10.
The controller is now
ready
