Electronic Control Panel; Installation; Start-Up; Maintenance And Repair - Xylem Lowara SEKAMATIK 10 E 15M Series Installation And Operation Instruction Manual

The end of the pump power supply cable must not be
submerged in order to prevent water from penetrating
through the cable into the motor.
The normal separate motor starter/control box of
standard as well as of explosion proof pumps must not be
not
be installed in explosive enviroments.
The electrical connection of the pump should be carried
out in accordance with local requirements.
The operating voltage and frequency are marked on the
pump and controller nameplates. Voltage tolerance:
+6% up to -10% of the voltage stated on the nameplates.
Make sure that the lifting station is suitable for the electricity
supply available at the installation site.
XYLEM disposal units are supplied with a control box.
Controller for single-phase pumps also incorporate the op-
erating capacitors required.
The pump motor has a thermal switch incorporated in the
motor winding. The thermal switch protects the motor from
overheating by cutting off the supply to the pump via the
controller.
The electrical connection must be carried out in accordance
with the marking on the cable to the controller.
The lifting stations require no additional motor protection.
Connect the units to the mains supply.
5.2. Electronic control box
The equipped electronic control box controls the operation
functions and announce failures which may be occure.
Operation switch
Position „OFF"
The pump is stopped.
Position „ON"
Pump operation according to the liquid level in the tank.
Test/ Reset-Switch
With this switch you can make a test-run of the pump
and can check the motor-overrun-time. This makes sure
that no solids are in the cutting device, which will avoid
a re-start of the pump.
The controller front cover features Light-Emitting Diodes
(LED) for indication of operating conditions:
Green LED „Operation"
The green LED illuminates when the pump is operating.
Red LED „Alarm"
- The red LED illuminates in case of a thermal cutout of
a pump. In this case please wait that the motor can cool
down, after this time the pump will switch on again.
- The red LED illuminates in case of a blocked impeller
by impurities. Before repair please disconnect the pump
from the power supply and clean the tank by hand and
remove solids which may block the pump.
- The red LED illuminates in case of a blocked motor. In
this case press the Test/ Reset-Switch. If the red LED
does not turn off and the pump still does not work,
please contact your XYLEM service.

6. Installation

The operator has to prevent damage through the flood-
ing of rooms caused by defects of the pump through the
use of appropriate measures (e.g. installation of alarm
units, backup pump or like that).
Fasten the tank to an even floor with expansion bolts.
Before installing the disposal units make sure that the all
national instrucions and the general measures for health
protection and industrial protection for the installation of
disposal units (DIN 1986) are observed. Furthermore
please pay attention to the hints below:

Install the unit in that way, that the operation and ser-
vice elements are easily accessable. Make sure that
there is enough space (approx. 50 cm) between the
horizontal inlet and any wall.

Mount a gate valve into the inlet pipe and the dis-
charge pipe to guarantee an easy service or demount-
ing of the unit.

To avoid sediment build-up in the discharge pipe, the
pipe, and the lifting station should be dimensioned for
a water velocity of minimum 0,7 m/s, for vertical pipes,
however, not lower than 1,0 m/s.

The incoming sewer could be ensues at the horizontal
inlet through a WC-direct connection with 180 or 250
mm, or a DN 100 or DN 50 effluent pipe. Vertical inlets
(DN 50 and DN 100) for service pipe lines are existing.
Cut off the blanked off the vertical or horizontal inlet
and connect a incoming sewer inlet which correspond
to the diameter of the inlet.

To prevent a freezing of the discharge pipe please iso-
late the complete discharge pipe up to the sewer level.

Directly above the swing check valve (SEKAMATIK 50
E/D have an integrated swing check valve) mount a
gate valve into the discharge pipe.

For a trouble free operation of the pneumatic level con-
trol it is absolutly necessary that the pressure hose be-
tween tank and control box is installed without loops,
bending and constantly rising.

Cut off the blanked off end of the air vent and connect
a DN 70 vent pipe to the tank by means of the flexible
connection supplied. The vent pipe should be led out
into the open air in accordance with local regulations.

Mount the supplied pump controller flood protected on
the wall in accordance with local regulations.

7. Start-Up

Never let the pump run dry for a long time of period,
as it will destroy the pump (danger of overheating).
Before starting the disposal unit make sure that all isolating
valves are open and check that the unit runs satisfactorily.
Turn the operation switch into the position "ON".
In combination with the pneumatic level control the pump
starts and stops according to the liquid level in the tank.

8. Maintenance and Repair

In case of a defect of the pump, a repair shall be car-
ried out only by the manufacturer or through an authorized
workshop. Modifications of the pump must be confirmed by
the manufacturer. Only XYLEM spare parts shall be used.
In accordance with the product liability law we point out
that we shall not be liable for damages caused by our
product due to unauthorized repair by persons other than
the manufacturer or an authorized workshop or due to the
use of spare parts other than original XYLEM parts. The
same product liability limitations are valid for accessories.
Before maintenance or repair disconnect the pump
from the power supply to avoid accidental starting of the
pump!
