Danfoss VLT HVAC Series

EXAMPLE 3:
Variable value= REFERENCE, range= Min ref - Max ref
Range needed for output= Min ref (0%) - Max ref (100%), 0–10 mA
Output signal 0 or 4 mA is needed at Min ref - set par.6-51
Terminal 42 Output Min Scale to 0%
Output signal 10 mA is needed at Max ref (100% of range) - set par.6-52
Terminal 42 Output Max Scale to 200%
(20 mA / 10 mA x 100%=200%).

6-53 Terminal 42 Output Bus Control
Range: Function:
0.00 %* [0.00 - 100.00 %] Holds the level of Output 42 if controlled by bus.
6-54 Terminal 42 Output Timeout Preset
Range: Function:
0.00 %* [0.00 - 100.00 %] Holds the preset level of Output 42.
In case of a bus timeout and a timeout function is selected in par.6-50
Terminal 42 Output , the
output will preset to this level.
3.8.8 6-6* Analog Output 2 MCB 101
Analog outputs are current outputs: 0/4–20 mA. Common terminal (terminal X30/8) is the same terminal and electrical potential for analog common
connection. Resolution on analog output is 12 bit.
