Function
The Fluid Manager integrates the functions of a breather filter,
level and temperature monitors, and a return flow filter.
The constructive design provides for flexible fitting of equip-
ment, which allows the device to be adjusted to suit the re-
quirements of the application at hand.
The Fluid Manager consists of a cast base plate, into which the
filter head of the return flow filter is integrated.
The filter head is provided with three threaded ports, which are
offset by 90°, for the variable connection of the return line.
The sample-taking port can be optionally mounted to ports X1
or X3.
In addition, a port X2 is provided in the return flow line.
The base plate is fitted with a connecting flange to
DIN 24550/T2. Variant NTR includes a breather filter with level
and temperature monitor. On function variant R, a breather fil-
ter or float switch can optionally connected to this connecting
flange.

Clogging indicator type ..E2SPSS.. (dimensions in mm [inch])
Clogging indicator type E2SPSS is a microprocessor-controlled pressure sensor. As the filter is increasingly clogged, the rising
backpressure upstream of the filter element is measured.
The pressure sensor is fitted with 2 switching outputs for pre-warning at 75 % (4 yellow LEDs) and maximum clogging at 100 %
(4 red LEDs).
In order to avoid false alarms due to high viscosity during the cold start phase, a temperature sensor measures the oil temperature.
The device is ready at a temperature > 30 °C (4 green LEDs).
Features:
– Two switching outputs
– Signal suppression during the cold start phase and for brief pressure peaks
– Visual / electrical display
– Self-monitoring (a fault is indicated by flashing of the red LEDs and switching output 2 is activated)
– Illuminated LED circle visible all around
– Display of status and fault messages
– Circular plug-in connection M12 x 1
– Reset function

Commissioning
Before commissioning, check that
– all connections fit properly and do not show any defects,
– the base plate was mounted stress-free on the tank,
– a filter element was inserted in the return flow filter,
– a tank breather filter or a level / temperature measuring device is installed.
Port D – variants with clogging indicator:
The technical connection data for clogging indicator type ..RV2.. and
type ..E2SPSS.. can be found on pages 5, 10 and 11, and data sheet RE 50088.
Installation notes
– Ensure sufficient distance to the tank wall and components
– Ensure free access to ports for the return flow filter, sample-taking and port E
– Make sure that there is sufficient space upwards for changing the filter elements
– The return flow filter can be connected to T1, T2 or T3
– The pressure measuring fitting with the sample-taking tube can be connected to X1 or X3
Electrical connections:
– Electrical connections may only be established by specialist personnel
– Before working on electrical components, interrupt the power supply
– After having connected the circular plug-in connection M12 x 1 tighten it my means of screws
– Only connect the circular plug-in connection M12 x 1 when disconnected from the power supply
– Do not overload contacts (see Technical data)
– In the case of inductive load, provide protective circuit!
Note
The electronic clogging indicator is provided with an illuminated circle of LEDs which is visible from all directions. These LEDs sig-
nal, apart from usual status messages, additional fault messages.
If the switching outputs were activated due to excessive pressure, they can only be deactivated by switching the system off or
when the hydraulic fluid temperature falls again below 20 °C.
To trigger a switching process, the pressure must have exceeded the corresponding limit value (2.2 or 2.9 bar) without any inter-
ruption. This prevents the alarm from being triggered by brief pressure peaks.
Press the reset key after each filter change!
Green LED permanently ON Supply voltage is applied and device is ready
