DESCRIPTION
FUNCTION
0 LINEAR
The drive will always start the fixed
pumps by following the same
sequence 1, 2, 3 and will stop them
in the same way 1, 2, 3 (no
alternation).
1 CYCLE
The first pump to start will be the
next one to the last stopped pump.
2 DUTY
SHARE
The drive will try to make the
operation times of all available
pumps equal.
YES

JOCKEY ON PRESS
G25.9.7
/
Starting pressure
of Jockey pump
0.0 – 3276
Engineering
units
0.0Bar
It sets a pressure level below which, the Jockey pump will start.
During periods of very low demand (for example, tank filling process
or opening of a couple of taps) the Jockey pump will start to cover
this demand. This pump will only start if the drive is sleeping and
additionally there is some relay configured in Jockey Pump mode.
Consult configuration of the outputs for additional information.
YES
8 JPon DLY=20s
JOCKEY ON DELAY
G25.9.8
/ Start
delay time for
Jockey pump
0 to 6500s
20s
It allows setting a delay time for the starting of Jockey pump. This
time will start elapsing after the starting condition of this pump is
met, this is, when the pressure is below the level set in G25.9.7.
YES

pressure of
Jockey pump

0.0Bar
Setting of the level above which Jockey pump will stop. If the drive
pump starts, then the Jockey pump will stop automatically although
this stopping pressure is not reached.

Once stopped the priming pump and started the drive, if the input
configured as Pressure Switch is opened during this time, the fault
‘F72 IN PRES SW’ will be produced.
Note
: The fault F72 is only produced if there is some relay
configured as ’30 PRIMING PUMP’ and some digital input
configured as ’69 PRESSUR SWITC’.

If the priming pump is connected and this time has elapsed from the
starting of the same one without detecting pressure in the pressure
switch, the fault ‘F72 IN PRES SW’ will be produced.
Note
: The fault F72 is only produced if there is some relay
configured as ’30 PRIMING PUMP’ and some digital input
configured as ’69 PRESSUR SWITC’.

G25.10.2
/
Maximum
allowed flow

Engineering
units
1000 l/s
Setting of the maximum value of the allowed flow.
When the flow value is higher than the value set in (G25.10.2 +
G25.10.3), the flow control algorithm will be activated showing
‘FLOW’ as drive status.
At this point, the pump speed reference will start to decrease by
using the ramp set in G25.10.5. The speed reference will decrease
until the present flow is lower than the value set in G25.10.2 minus
the margin set in G25.10.3. In that moment, the speed will remain
constant until the present flow is lower than the flow set in G25.10.4.
From this moment on, the PID regulator will take up the control
again, and the drive will start to regulate normally.
Note:
Default units of measurement which are displayed depend on
the selected engineering units.
