Device functions
Version 1 UPT-6006 Page 33
8.7.1 Temperature range and alloy
With this parameter, both the temperature range and the heating element alloy can be selected. By changing the
standard value (10), the setting of the rotary coding switch (
 section 7.2.2 "Configuration of the rotary coding
switch for temperature range and alloy" on page 16) can be overwritten.
After a change of this parameter, the AUTOCAL function must be performed.
8.7.2 Lower threshold for temperature OK
Lower threshold value for the “good window”.
See section 8.6.6 "Temperature OK (TO)" on page 28 and section 8.7.12 "Temperature diagnosis" on page 35.
8.7.3 Upper threshold for temperature OK
Upper threshold value for the “good window”.
See section 8.6.6 "Temperature OK (TO)" on page 28 and section 8.7.12 "Temperature diagnosis" on page 35.
8.7.4 Variable calibration temperature
The calibration temperature is set as standard to 20 °C. It can be changed between 0 °C and 40 °C and thus
adapted to the temperature of the cooled-off heating element.
With some PROFIBUS masters, the parameter data cannot be changed during operation. Adjustment of the cali-
bration data to the current ambient conditions in the machines is therefore not possible.
The calibration temperature can therefore be released for setting through the input data by specifying the value “-
1” in the parameter data. Specification of the calibration temperature is then made through the input data “Setpoint/
AC temperature” (
 section 8.5.2 "AUTOCAL autom. zeroing (AC)" on page 25).
After a change of the calibration temperature, the AUTOCAL function must be performed.
8.7.5 Heating time limit
With the heating time limit, additional monitoring can be done before unintended permanent heating. The controller
automatically switches off the heating impulse after the set heating time limit has passed when the ST bit should
remain set longer than the time set through the heating time limit. The ST bit must be reset before the controller
is started again.
The heating time limit is switched off as standard (value 0) and can be selected between 0 s and 9.99 s (0 and
999).
