302 Reference offset for current input 12 (2.15, 2.2.3)
0 No offset: 0—20mA
1 Offset 4 mA (“living zero”), provides supervision of zero level signal. In Standard
Application, the response to reference fault can be programmed with parameter
ID700.
303 Reference scaling, minimum value 2346 (2.2.4, 2.2.16, 2.2.2.6)
304 Reference scaling, maximum value 2346 (2.2.5, 2.2.17, 2.2.2.7)
Setting value limits: 0 ≤ par. ID303 ≤ par. ID304 ≤ par. ID102. If both parameter ID303
and parameter ID394 = 0 scaling is set off. The minimum and maximum frequencies are
used for scaling.
