Default set-point: internal set-point
For the internal default set-point, the set-point for the flow is entered into the
previously set unit and stored. The unit regulates to this value.
Settings between 0 and 655.2 are possible. If an attempt is made to enter a higher
value, the display will jump automatically to 0 and a value within the range must be
entered. The decimal point cannot be set in the first (left) position. The units
correspond to the value set in the"UNIT" menu point.
(factory setting: 0,00)
NOTE
Example:
Set K factor:
Desired set-point:
=> Frequency of the flow sensor:
f = Q * k
= 300 l / s * 4 pulses / l
= 1200 Hz
=> f > 1000 Hz, i.e. cannot be read in
=> Settable set-point: 0 - 250 l / s
(corresponds to the frequency 0 - 1000 Hz)
=> For higher flows, a sensor with a lower K factor must be used!
Operating Instructions No. 803 052
The setting up of the set-point can only take place up to a value
corresponding to 1000 Hz. Setting of the set-point outside this limit
is not possible.
