6. It is necessary to read the parameters from the device to the computer after changing the scale (1/1, 1/10
or 1/100) settings. This is in order to refresh the parameter list so the alarm settings present the correct value.
7. After reading the parameters, the alarm has been scaled so it needs to be adjusted (0-5 in this example),
and this is also a scaling of the value on the display.
The display will now show the scaled value of multi-input 6.
In the example shown above, the value can be adjusted with two decimals. If the parameters were not re-
freshed, it would still only be possible to adjust the setpoint without decimals.
Save the parameter file:
After having set up the 4-20 mA inputs (HW as well as alarms), the parameter file should be uploaded from
the device to the PC and then saved. In this way, the settings will not be modified again if the parameters are
reloaded to the device.
6.21.9 Digital
If the multi-inputs are configured to "Digital", they become available as digital inputs which means a switch
function input.
6.21.10 Pt1000
This input type can be used for heat sensor, for example cooling water temperature. The unit of the measured
value can be changed from Celcius to Fahrenheit in the PC utility software in order to get the desired reading
in the display. The setting is located in parameter 10970 and is only accessible from the utility software.
An offset parameter is used for compensation of wire resistance in a 2-wire setup.
Pt1000 offset can be configured in the following parameters:
● Multi-input 6: 4167
● Multi-input 7: 4297
