Function

Adaptation of field-frequency related parameters

C010, C011, C017, C019, C037, C038, C039, C046, C049, C050 and

for controllers of the “HVAC” series C051, C181, C625, C626, C627 additionally

to an application datum to be controlled, e.g. pressure, temperature, flow rate, humidity or speed.
The normalisation

implements an absolute or relative selection or display of an application datum,

is always carried out simultaneously for all codes indicated.

Adjustment

The display value is calculated from:

CXXX

C011

200 ô

C500
C501

Example

The speed setpoint is to be input and displayed as relative or absolute value.
Values: P

set

= 5 bar, if f

dmax

= 50 Hz (C011)

a) Relative normalisation in %

100.00 (%)

200 ô

4000

e.g. C500 = 4000, C501 = 10

b) Absolute normalisation in physical units

5.00 (bar)

200 ô

200

e.g. C500 = 200; C501 = 10

Important

All codes indicated above are normalised at the same time.

After a normalisation, the output frequency [Hz] (C050) can only be recalculated with the display
factors C500 and C501.
