10.7.5 Setpoint influence (4.1.3)
Fig. 30
Setpoint influence
Description
The setpoint may be influenced by several factors so that the
current setpoint is adapted to parameters which are to influence
for instance the discharge pressure of the booster set.
The parameters which influence the performance of the booster
set are shown as a percentage from 0 to 100%. They can only
reduce the setpoint, as the influence is multiplied with the
setpoint:
The influence values can be set individually.
Factory setting
Setpoint influence is not activated.
10.7.6 External setpoint influence (4.1.3.1)
Fig. 31
External setpoint influence
Description
This function makes it possible to make an external analog signal
influence the setpoint. The analog signal may be a 0-100% signal
from another control unit, a signal transmitter such as a flow
sensor, or a parameter in the system.
The function is linked to a selected analog input (AI), and the
relation between the measuring parameter and the desired
influence in percentage is described in a table with maximum
eight points.
Setting range
The following parameters can be selected:
•
Not used
•
0-100% signal
•
Inlet pressure
•
Discharge pressure
•
External pressure
•
Differential pressure of pump
•
Flow rate
•
Tank level, discharge side
•
Tank level, suction side.
