Up to September 2005:
8. Activate the AUTOCAL function while the heatsealing band is still cold (with the manual button on the con-
troller). The yellow "AUTOCAL" LED lights up (up to September 2005: Twin-color LED blinks red and green
alternately) the duration of the calibration process (approx. 10…15s). A voltage of app. 0VDC appears at the
same time at the actual value output (terminals 14+15). If an ATR-3 is connected, it indicates 0…3°C.
When the zero point has been calibrated, the "AUTOCAL" LED goes out (up to September 2005: The twin-color
LED flashes green every 1.2s then) and a voltage of 0.66VDC appears at the actual value output instead. If an
ATR-3 is connected, it must be set to "Z".
If the zero point has not been calibrated successfully, the red "ALARM" LED blinks slowly (1Hz) (up to Sep-
tember 2005: Twin-color LED blinks red slowly). In this case the controller configuration is incorrect
(
section 5.9 "Controller configuration" on page 14 and ROPEX Application Report). Repeat the calibration
after the controller has been configured correctly.
9. When the zero point has been calibrated successfully, set a defined temperature on the set point potentiometer
and activate the "START" signal (HEAT). The "HEAT" LED then lights up (up to September 2005: the twin-color
LED "HEAT" 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) has a harmonious motion, 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 wires have been wired incor-
rectly.
10.Burn in the heatsealing band (
section 5.10 "Replacing and "burning in" the heatsealing band" on page 15)
and repeat the AUTOCAL function.
5.11.2 Restart after replacing the heatsealing band
To replace the heatsealing band, proceed as described in section 5.10 "Replacing and "burning in" the heatsealing
band" on page 15.
Always use a heatsealing band with the correct alloy, dimensions and copper-plating in order to
avoid malfunctions and overheating.
