(Pos. 6.3) - Range and function of analog output [Out mA1=X÷XX±]
This parameter defines the operating mode and has 3 input fields:
- Field 1: Initial value 0 or 4 mA
- Field 2: Final value 20 or 22 mA
- Field 3: Flow direction + = positive, - = negative, "blank" = both, -0+ = zero point in the middle (12 mA)
The following combinations are possible:
Current in mA , related to the full scale value in %
Permitted inputs
Current mA = 0 ÷ 20 +
Current mA = 0 ÷ 22 +
Current mA = 4 ÷ 20 +
* Current mA = 4 ÷ 22 +
Current mA = 0 ÷ 20 -
Current mA = 0 ÷ 22 -
Current mA = 4 ÷ 20 -
Current mA = 4 ÷ 22 -
Current mA = 0 ÷ 20 ±
Current mA = 0 ÷ 22 ±
Current mA = 4 ÷ 20 ±
Current mA = 4 ÷ 22 ±
Current mA = 0 ÷ 20 – 0 +
Current mA = 0 ÷ 22 – 0 +
** Current mA = 4 ÷ 20 – 0 +
Current mA = 4 ÷ 22 – 0 +
If a hardware alarm occurs, the initial value is calculated via the function "mA v.fault % (pos. 4.5) and indicated as a percentage value of
the fixed current range, whereby 0% = 0 mA and 110% = 22 mA.
