Settings:<br />
1. Settings on temperature / current range<br />
Select analogue interface / config. input / adjust measurement range<br />
Enter the temperature range to correspond to 0/4-20mA (T1=0 °C, T2=100<br />
°C).<br />
2. Select input signal<br />
Select the input signal (AIF-> set-point) via analogue interface / config. input /<br />
AIF-Input - Function<br />
3. Select output signal<br />
Select the output signal (Process temp.) via analogue interface / config. output /<br />
output range<br />
4. Select action if cable breaks<br />
Select analogue interface / config. input / on cable break<br />
Trigger an alarm.<br />
5. Select action upon analogue error<br />
Select analogue interface / config. input / on analogue error<br />
Switch off.<br />
6. The settings can be reviewed by selecting:<br />
analogue interface / config. input / display AIF values.<br />
Please note that the fine signal adjustment functions the same for the analogue output<br />
as it does for the input.<br />
Setting information for fine adjustment.<br />
General: When the machine is delivered and after a Reset (Reset AIF input) the interface<br />
will be set accurately enough. An adjustment is not necessarily required.<br />
It is possible at any time to adjust the precision of the input channel. This could be<br />
required if the set-point input current does not coincide with the expected temperature<br />
value. If as shown in point 1 above, an input of 4.000mA does not give exactly 0°C,<br />
but maybe 1°C. A fine adjustment can then be made. Change to menu point analogue<br />
interface / config. input / fine adjust / xxxxx. Feed 4.000mA into the interface. Confirm<br />
the value. Choose then analogue interface / config. input / fine adjust / xxxxx. Feed<br />
then 20.000mA into the interface. Confirm the value. At the end, a current input of<br />
exactly 4.000mA should give a set-point of 0°C and a current input of 20.000mA<br />
should give a set-point of 100°C.<br />
The fine adjustment of the output channel is done in a similar manner. A sensor value<br />
of 0°C and 100°C should give an output current value of 4.000mA and 20.000mA.<br />
