UPT-606
8.2.3
Configuration of the rotary coding
switches for the station address
The station address of the UPT-606 in the PROFIBUS
network can be set between 0 and 99 with these coding
switches. A new setting does not take effect until the
next time the controller is switched on.
8.2.4
Configuration of the alarm relay
If the jumper is not inserted, the alarm relay
is permanently energized when using a con-
troller up to software revision 015. The other func-
tions of the controller (e.g. heating, AUTOCAL etc.)
are not impaired by this.
If the plug-jumper is not inserted when using a con-
troller as of software revision 100 - or if it is incor-
rectly inserted - an error message appears when
the controller is switched on (
section 9.13 "Error
messages" on page 40).
If the "Alarm relay deenergized by alarm/PC CONFIG-
URATION" position is selected (as of software
revision 100), the behavior of the alarm output can be
configured in more detail by means of the ROPEX visu-
alization software (
see section 9.11 "Diagnostic
interface/visualization software (as of software
revision 100)" on page 39).
8.3
Heating element
8.3.1
General
The heating element is a key component in the control
loop, since it is both a heating element and a sensor.
The geometry of the heating element is too complex to
be discussed at length here. We shall therefore only
refer to a few of the most important physical and elec-
trical properties:
The measuring principle applied for this system neces-
sitates a heating element alloy with a suitable tempera-
ture coefficient TCR, i.e. one whose resistance
increases as the temperature rises.
Too low a TCR leads to oscillation or uncontrolled hea-
ting.
When heating elements with a higher TCR are used,
the controller must be calibrated for this.
