Danfoss vlt aqua Operating Instructions

29-03 Pipe Fill Time
Range: Function:
0 s* [0 - 3600 s] Set the specified time for pipe filling of horizontal pipe systems.
29-04 Pipe Fill Rate
Range: Function:
0.001 units/
s*
[0.001 – 999999.999 units/s] Specifies the filling rate in units/second using the PI controller. Filling rate units are feedback units/
second. This function is used for filling-up vertical pipe systems but will be active when the filling-
time has expired, no matter what , until the pipe fill-set-point set in par. 29-05 is reached.
29-05 Filled Setpoint
Range: Function:
0 s* [0 – 999999,999 s] Specifies the Filled Set-point at which the Pipe Fill Function will be disabled and the PID controller
will take control. This function can be used both for horizontal and vertical pipe systems.
