SDRIVE 700
POWER ELECTRONICS
Function
It allows setting the pressure level, below which the Jockey pump will start.
During periods of very low demand (for example, tank filling processor opening 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 output relay (parameters
‘G8.1.1 Î Selection of Relay 1 control source’, ‘G8.1.5 Î Selection of Relay 2 control
source’ and ‘G8.1.9 Î Selection of Relay 3 control source’) configured with the option
’29 Î JOCKEY PUMP’.

Extended info.
Description
Range
Default value
Set on run
8 JPon DLY=20s
Start delay time for Jockey pump.
0 – 6500s
20s.
YES.
Function
It allows setting a delay time to start the Jockey pump.
JOCKEY ON DELAY
This time will start elapsing after the condition to start this pump is fulfilled, this is,
when the pressure is below the level set in parameter ‘G25.9.7 Î Starting pressure of
Jockey pump’.

Description
Range
Default value
Set on run
9 JPof P=0.0Bar
Stopping pressure of Jockey pump.
0.0 – 3276 Engineering Units
0.0Bar.
YES.
Function
It allows setting the pressure level, above which the Jockey pump will stop.
JOCKEY OFF PRESS
If the drive pump starts, then the Jockey pump will stop automatically although the
pressure level set in this parameter is not reached.
G25.9.10 BYPASS TIME FOR PRIMING PUMP
Screen
Extended info.
Description
Range
Default value
Set on run
10 PRp BYP=300s
Function
It allows setting the bypass time for the Priming pump.
PRIM.PUM.BYP.DLY
Bypass time for the Priming pump.
0.1 – 6000s
300s.
YES.
Once stopped the Priming pump and started the drive, if the digital input configured as
pressure switch (parameter ‘G4.1.5 Î Multi-function Digital Input 1 configuration’ to
‘G4.1.10 Î Multi-function Digital Input 6 configuration’, option ’69 Î PRESSUR
SWITC’) is opened during the time set in this parameter, the fault ‘F72 IN PRESS SW’
will be produced.
Note:
The fault F72 is only produced if there is some output relay configured with the option
’30 Î PRIMING PUMP’ (parameters G8.1.1, G8.1.5 and G8.1.9) and some digital
input configured with the option ‘69 Î PRESSUR SWITC’ (parameter G4.1.5 to
G4.1.10).
