The pump type is defined by
the last 5 digits of the DCP or-
der code.
Single or Double pump
Displacement of pump 1
[ccm/rev]
Displacement of pump 2
[ccm/rev]
Function
By selecting the appropriate
type of pump, all relevant pa-
rameters such as displace-
ment, min. / max. speed, max.
pressure and number of pumps
(double pump (yes / no)) are
set automatically.
If the pump is not configured
via the DCP code, this pa-
rameter selects between sin-
gle or double pump. The DCP
code has to be set to default
(DCPxxxxxxxxxxxA0000).
If the pump is not configured
via the DCP code, this pa-
rameter sets the displace-
ment of pump 1. The DCP
code has to to be set to de-
fault (DCPxxxxxxxxxxxA0000).
If the pump is not configured
via the DCP code, this pa-
rameter sets the displace-
ment of pump 2. The DCP
code has to be set to default
(DCPxxxxxxxxxxxA0000).

Function
If the pump is not configured
via the DCP code, this param-
eter sets the min. speed of the
drive. If a double pump is se-
lected, the higher min. speed
of both pumps has to be se-
lected (entered). The DCP
code has to be set to default
(DCPxxxxxxxxxxxA0000).
If the pump is not configured
via the DCP code, this param-
eter sets the max. speed of the
drive. If a double pump is se-
lected, the lower max. speed
of both pumps has to be se-
lected (entered). The DCP
code has to be set to default
(DCPxxxxxxxxxxxA0000).
If the pump is not configured
via the DCP code, this param-
eter sets the max. pressure of
pump 1.
If a double pump is installed,
the max. pressure is a function
of the pump selection.
(e.g.: max. pressure of pump
1 = 300 Bar /// max. pressure
of pump 2 = 170 Bar. If both
pumps are used, the max. pres-
sure is p = 170 Bar. If the sec-
ond pump is deactivated (e.g.
via the digital input), the max.
pressure is set to p = 300 Bar.)
The DCP code needs to be
set to default (DCPxxxxxxx
xxxxA0000).
If the pump is not configured
via the DCP code, this param-
eter sets the max. pressure of
pump 2.
If a double pump is installed,
the max. pressure is a function
of the pump selection.
(e.g.: max. pressure of pump
1 = 300 Bar /// max. pressure
of pump 2 = 170 Bar. If both
pumps are used, the max.
pressure is p = 170 Bar. If the
second pump is deactivated
(e.g. via the digital input), the
max. pressure is set to p =
300 Bar.)
This parameter selects the application. Depending on the selected application, the control strategy and terminal usage change.
