22-45 Setpoint Boost
Range:
0 %* [-100 - 100 %]
22-46 Maximum Boost Time
Range:
60 s* [0 - 600 s]
3.17.4 22-5* AP-5# End of Curve
The End of Curve conditions occur when a pump is yielding a too large volume to ensure the set pressure. This can occur if there is a leakage in the
distribution pipe system after the pump causing the pump to operate at the end of the pump characteristic, valid for the max. speed set in par.

Set the reference speed at which the Sleep Mode should be cancelled.
Function:
To be used if par.0-02
Only to be used if par.1-00
by an external controller controlling the pressure.
Set the reference speed at which the Sleep Mode should be cancelled.
Function:
Only to be used if par.1-00
is used for controlling the pressure.
Set the pressure drop allowed in percentage of set point for the pressure (Pset) before cancelling
the Sleep Mode.
Wake-up Ref./FB Difference

Function:
Only to be used if par.1-00
troller is used. In systems with e.g. constant pressure control, it is advantageous to increase the
system pressure before the motor is stopped. This will extend the time in which the motor is stopped
and help to avoid frequent start/stop.
Set the desired over pressure/temperature in percentage of set point for the pressure (Pset)/tem-
perature before entering the Sleep Mode.
If setting for 5%, the boost pressure will be Pset*1.05. The negative values can be used for e.g.
cooling tower control where a negative change is needed.
Function:
Only to be used if par.1-00
is used for controlling the pressure.
Set the maximum time for which boost mode will be allowed. If the set time is exceeded, Sleep
Mode will be entered, not waiting for the set boost pressure to be reached.
