Scaling
The frequency input value can be scaled to a physical value in two points.
1st value:
– input Frq.L (value specified in kHz)
– physical value Ou.L
2nd value:
– input Frq.H (value specified in kHz)
– physical value Ou.H
Example:
5 Hz
= 2 l/min
20 Hz = 30 l/min
Settings: Frq.L = 0,002; Ou.L = 5
Frq.H = 0,020; Ou.H = 30
Filter
The frequency input value can be filtered (Parameter Frq.F).
Exceeded frequency range
g
When exceeding the frequency input range end, measurements are switched off during approx. 1 s.
Out-of-range signalling is possible via an output signal: ConF / Out.x / FAi.F = 1
Simulation
A special “Freq” input window is provided for simulation of the frequency input in the BlueControl ® engineering tool.
It should be specified in kHz.
6.10 Arithmetic functions
The following arithmetic functions are available in configuration setting CONF / Fnc.2 :
Square function
• Formula: x
2
The display value which is squared is output.
Square root extraction
• Formula:
Öx
For output, the square root of the display value is extracted.
For values x
£ 0 , value 0 is output.
