8.7.3
Low temperature OK threshold
Low threshold value for the "OK" window.
Refer to section 8.6.6 "Temperature OK (TO)" on page 28 and section 8.7.11 "Temperature diagnosis" on
page 55.
8.7.4
High temperature OK threshold
High threshold value for the "OK" window.
Refer to section 8.6.6 "Temperature OK (TO)" on page 28 and section 8.7.11 "Temperature diagnosis" on
page 55.
8.7.5
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 heating element.
Some EtherNet/IP
TM
scanners do not allow the parameter data to be changed during operation. In this case, the
calibration 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.
8.7.6
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 start 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 activated by default (5.00 s) but can be set to any value between 0 s and 9.99 s (0 and
999).
8.7.7
Measuring impulse duration
The length of the measuring impulses generated by the controller can be set with the parameter at index 10. It
may be necessary to set a measuring impulse longer than the default 1.7 ms for certain applications.
8.7.8
Data format
This parameter specifies the order of the bytes ("Little Endian (Intel)” or "Big Endian (Motorola)") in the cyclic data;
this setting applies to both input and output data (
section 8.4 "Communication protocol" on page 24).
We recommend selecting "Big Endian (Motorola)" for Siemens PLCs.
8.7.9
Correction factor Co
The correction factor Co allows you to adapt the controller to the actual conditions in the machine (type of UPT
heating element, impulse transformer specification, length of connecting cables, cooling etc.). You can set the
required correction factor with this parameter.
Proceed as follows to determine the optimum correction factor Co:
1. Controller settings:
- Set temperature: 160…180 °C
- Sealing time:
0.20…0.30 s
2. Heating impulses (ST bit = 1):
Proceed as described in section 8.5.2 "Start (ST)" on page 26.
