This section is relevant for:
n
Integral XT devices
The pump of the device can be adjusted by means of several pump levels.
This optimizes the flow rate and discharge pressure, noise generation and
mechanical heat input.
If you have connected a pressure-sensitive application, you must use
the settings
[Set pump pressure]
(
Pump
Pressure control
Set pump press.) and
[Max. pressure]
in the Pump menu.

Pump level
n
Through-flow control
The Flow control menu is only displayed if an MID flow controller
has been connected.
n
Pressure control with entry window for the set pump pressure
As an alternative to the 8 pump power stages, operation with pres-
sure control is provided. The device then regulates to the set pres-
sure and enables a careful supply of pressure-sensitive consumers.
You enter a value in this entry window when you have connected a
pressure-sensitive consumer. This value in the bar unit depends on
the sensitivity of your consumer. If you enter a setpoint of 0 bar,
the pressure control is switched off.
n
Pressure control variables
No settings can be made here.
Pump pressure: Displays the current pressure of the pump in the
outflow.
Outfl. Press. FC
Displays the pressure currently measured at the output of the flow
controller. The menu is only displayed if a flow controller has been
connected.
Extern Ethernet and Extern analog: Displays the externally meas-
ured pressure supplied via the interface.
n
Max. pressure
This entry serves to protect your application. Set the maximum
pressure to a level which cannot damage your connected applica-
tion. The set pressure must be lower than the maximum pressure.
If the maximum pressure you entered is exceeded, the device
switches off. Pump, heater and cooling unit are switched off.
n
Auxiliary pump
The menu is only displayed if an auxiliary pump has been connected.
