slowly (1 Hz). In this case the controller configuration is incorrect (
section 7.2 "Device configuration" on
page 16, ROPEX Application Report). Repeat the calibration after correcting the controller configuration.
9. After the zero point has been successfully calibrated, specify a defined temperature by means of the EtherCAT
®
protocol (set point) and set the ST bit. The RA bit (control active) is then activated and the "HEAT" LED 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 or the actual value in the EtherCAT
®
protocol) is a regular curve, in other words it must not jump abruptly,
fluctuate, or temporarily deviate in the wrong direction. This kind of behavior would indicate that the U
R
mea-
surement cable was laid incorrectly.
If an error code is displayed, proceed as described in section 8.19 "Error messages" on page 50.
10.Burn in the heatsealing band (
section 7.3 "Replacing and burning in the heatsealing band" on page 18) and
run the AUTOCAL function again.
7.4.2
Restart after replacing the heatsealing band
To replace the heatsealing band, proceed as described in section 7.3 "Replacing and burning in the heatsealing
band" on page 18.
Always use a heatsealing band with the correct alloy, dimensions, and copper plating in order to
avoid malfunctions and overheating.
Continue with section 7.4, steps 3 to 10.
