UPT-6011
Version 5
This reference value serves to calculate the deviation from the calibration value for all subsequent calibrations (ini-
tiated with the AC bit). This deviation helps you assess aging of the heating element.
The deviation from the calibration value is queried by means of the parameter object.
8.5.6
Channel selection (CH0…CH2)
The temperature controller has separate memories for up to eight calibration data records. A calibration data
record contains the values determined by the temperature controller during the "AUTOCAL" function. By storing
the calibration data records, you can alternate between different sealing tools without having to run the AUTOCAL
function every time the tool is changed. You only need to execute AUTOCAL if you connect a new heating ele-
ment.
Since different calibration values, AUTOCAL temperatures, correction factors, and temperature coefficients are
stored in the controller for this purpose, the required calibration data record 0…7 can be selected with the three
bits CH0…CH2. You can switch to another channel at any time.
This function is useful, for instance, in applications where frequent changes of format are necessary. The tools
can then be changed as required in order to handle the different formats. A channel containing the relevant cali-
bration data record is assigned to each tool. Once all tools have been calibrated with a unique channel assign-
ment, they can be changed at any time simply by selecting the appropriate channel.
If the application does not require any format changes, the channel can remain set to 0. In this case, the temper-
ature controller behaves in exactly the same way as older models where different calibration data records are not
supported.
It is possible to switch to another channel during the "AUTOCAL" function; however, the controller continues
working with the original channel until the "AUTOCAL" function has finished. The channel currently being used by
the controller is shown in the status information.
8.5.7
Set point
A set point of up to 300 °C or 500 °C is allowed, depending on the selected temperature range (
"Temperature range and alloy" on page 53). If you attempt to enter a higher set point, it is limited internally to
300 °C or 500 °C.
8.6
Output data
The term "output data" refers to the data that is transferred from the UPT-6011 to the EtherNet/IP
TM
scanner. It
contains the current actual value as well as all important information on the current status of the controller. If a fault
is signalled, it can be diagnosed accurately with the help of the error code.
8.6.1
AUTOCAL active (AA)
The "AA bit indicates that the AUTOCAL function is executing.
8.6.2
AUTOCAL blocked (AG)
If the AG bit is set, the AUTOCAL function is temporarily blocked. This is the case if "START" is active or the
heating element is still in the cooling phase.
8.6.3
Alarm active (AL)
If the AL bit is set, an alarm has been triggered but not yet reset. The error code provides information on the exact
cause (
section 8.19 "Error messages" on page 67).
Note:
In order to determine whether the temperature controller is ready for the sealing process, the alarm active (AL)
and
standby active (SA) bits must be queried. If both bits are set to "0", all prerequisites are fulfilled and the sealing
process is possible (
