Version 1
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 29 and section 8.7.11 "Temperature diagnosis" on page 37.
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 29 and section 8.7.11 "Temperature diagnosis" on page 37.
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 26).
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 25.0 s (0 and
250).
8.7.6
Expanded device diagnosis
The expanded device diagnosis uses the diagnosis channel of the PROFIBUS protocol to report possible error
statuses of the RES-5006 to the PROFIBUS master. Text messages for every error status are stored in the GSD
file. The PROFIBUS master can automatically displayed them in case of a corresponding display possibility.
With the help of parameter no. 9, the expanded device diagnosis can be switched on or off. The expanded device
diagnosis is active in the standard setting.
Regardless of this parameter, the possibility remains of querying the device status over the user data.
DPV1 protocol expansion (alarm model):
Expanded device diagnosis is not available if the DPV1 protocol expansion (
section 8.8 "DPV1 protocol expan-
sions" on page 40) is used. The related DPV1 alarm model (
section 8.8.2 "DPV1 alarm model" on page 40)
must then be used. With parameter no. 9 of the GSD file, in this case the so-called DPV1 diagnosis alarm is
switched on or off.
If the previous expanded device diagnosis should continue to be used (e.g. for reasons of software compatibility),
a GSD version lower than v2.0 must be used. This automatically switches off the DPV1 function for the RES-5006
in the PROFIBUS master.
8.7.7
Measurement impulse duration
The length of the measurement impulses generated by the controller can be set with parameter no. 10. For certain
applications, it can be necessary to lengthen the measurement impulse beyond the standard 1.7ms.
