When the delay elapses, Delta bar (par 53) checks the pressure value for the set
time. If it remains where it is or increases, the drive stops.

Delay during which the inverter attempts to stop. Enabled when pressure and
frequency are constant. Connected with parameter 47.

N 0 100 Counts the number of times the continuous pump operating time exceeds the
hold time (par 58). By default, so as not to increase the number of leaks, the pump
must not operate for at least 45 mins. within a 24 hour timescale. If the "leaks"
message appears, check whether there are leaks in the system or check times and
settings.
