7 How to Work With the Analyser
7.3 Good to know
LAR | PROCESS ANALYSERS AG
7.3.4 Furnace On - Off
Manually switching the furnace on - off
Please switch off the oven for maintenance purposes only. This can be done in the "Service Actions"
view (Fig. 70, page 107). Frequent switching off and on reduces the life of the furnace. The meter is
equipped with a high-temperature furnace, which makes it possible, at high temperatures without cata-
lysts, to achieve complete conversion of the sample. The setpoint temperature is set at the factory and
is password protected. An intervention in the programming of the temperature controller is inadmissible
and can lead to damage of the oven. In case of temperature problems, contact the technical support of
the LAR (Chapter 15.1 on page 183).
7.3.5 Automatic Temperature Control
The controller labeled "Temperature Control" displays two values at the front of the analyser. The actual
value and the setpoint. With the help of the control knob "Temperature Monitor", the stove is switched
off when the temperature rises above 1250° C. It is located on the back wall in the device. To heat the
stove about 120 min = 2 h are needed. This corresponds to a heating rate of 10° C / min. These settings
are factory set and can not be changed.
7.3.6 Condensate pump on - off
The condensate pump runs continuously and is only switched off for care and maintenance purposes
(such as changing hoses). Switch on the condensate pump again after the care and maintenance work.
7.3.7 Date and Time
The date and time are visible in all views and can be found in the upper right corner of the screen. Chang-
es can be made in the PC Settings view (Chapter 7.3.10.1 from page 122).
7.3.8 Language
The language settings of the software are factory set and can be changed by the LAR Technical Support
(Chapter 15.1 on page 183) or an authorized service partner on the device.
7.3.9 Save
Storage is necessary for all changes made to the operating parameters and settings. Perform storage:
1. Settings have been changed (eg. parameters). Press "Enter" (only for number fields).
2. The floppy disk button appears in the status bar (upper right side). Press the "Disk" button and a
selection window will be displayed.
3. Select "Save changed parameter". A new window opens.
4. If the change is to be accepted, press the green "check mark" to confirm. If the change is not
accepted, press the red "X".
Notice
German and English are available as standard languages in the device. For other lan-
guages, please contact LAR technical support (Chapter 15.1 on page 183).
