9. Activate the AUTOCAL function while the heatse-
aling 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 dis-
play 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 17 and ROPEX Application Report). Repeat
the zero point calibration after the controller has
been configured correctly.
10.When the zero point has been calibrated suc-
cessfully, the main menu appears on the display
again. Then specify a defined temperature (heatse-
aling 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 tempera-
ture indicated on the display has a continuous
curve, in other words it must not jump abruptly, fluc-
tuate 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 44.
11. Burn in the heatsealing band (
sealing band" on page 25) and repeat the
AUTOCAL function.
9.7.2
Restart after replacing the heatse-
aling band
To replace the heatsealing band, proceed as described
in section 9.6 "Heatsealing band" on page 25.
Always use a heatsealing band with the cor-
rect 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
