8.7.1
Temperature range and alloy
This parameter determines both the temperature range and the heatsealing band alloy. You can overwrite the set-
ting of the rotary coding switch (
section 7.2.2 "Configuration of the rotary coding switch for the temperature
range and alloy" on page 17) by changing the default value (10).
You must always execute the AUTOCAL function after changing the "Temperature range / alloy", "Temperature
range", or "Temperature coefficient" parameter.
8.7.2
Low temperature OK threshold
Low threshold value for the "OK" window.
Refer to section 8.6.6 "Temperature OK (TO)" on page 27 and section 8.7.9 "Temperature diagnosis" on page 39.
8.7.3
High temperature OK threshold
High threshold value for the "OK" window.
Refer to section 8.6.6 "Temperature OK (TO)" on page 27 and section 8.7.9 "Temperature diagnosis" on page 39.
8.7.4
Variable calibration temperature
The calibration temperature is set to 20 °C by default. You can change it to another value between 0 °C and 40 °C
in order to adapt it to the temperature of the cold heatsealing band.
Some EtherCAT
®
masters do not allow the parameter data to be changed during operation. In this case, the cali-
bration temperature cannot be adapted to the actual ambient conditions in the machines.
The calibration temperature can thus be enabled for setting by means of the input data by specifying the value "-1"
in the parameter data. The calibration temperature can then be specified via the "Set point / AC temperature" input
data (
section 8.5.1 "Automatic zero calibration AUTOCAL (AC)" on page 25).
After a change of the calibration temperature, the AUTOCAL function must be performed.
8.7.5
Heating time limit
The heating time limit provides additional protection against unwanted continuous heating. The controller auto-
matically deactivates the heating impulse after the set heating time limit has elapsed if the ST bit remains set for
longer than the time specified with this limit. The ST bit must be reset before the controller can be started up again.
The heating time limit is deactivated by default (0) but can be set to any value between 0 s and 99.9 s (0 and 999).
