out on live electrical components, they should be
unplugged from the mains or the main switch turned
off and fuse unscrewed. A motor protection switch is
to be provided.
 Basically, all work on the pump or pump unit should
only be carried out when the pump is stationary and
not under pressure. All parts must be allowed to
return to ambient temperature. Make sure that no-one
can start the motor during such word. It is essential
that the procedure for stopping the system described
in the Operating Instructions is observed. Pumps or
pump systems that carry media that are dangerous to
health must be decontaminated before being taken
apart. Safety Data Sheets for the various liquids
handled. Immediately the work has been completed,
all safety and protective devices must be replaced or
restarted.
 Under EC machinery Directives, every machine must
be fitted with one or more emergency command
devices by which situations which represent an
immediate danger or which could later be dangerous
can be avoided.
 If the emergency command device is no longer
operated after an emergency "off" switch has been
triggered, this must be maintained by blocking the
emergency command device until it is released
again. It should not be possible to block the device
without this triggering an emergency "off" switch. It
should only be possible to release the device through
an appropriate action; this release should not start
the machine up again – it should only make it
possible to start it up again.
 If the power supply is interrupted or restored after
being interrupted or if it is changed in any other way,
this should not cause any danger (e.g. start up
without control or unexpected, pressure hammer).
2. Applications and Technical Description
2.1. Applications
This disposal units are used for pumping waste water,
effluent or groundwater, containing sludge or soft solids from
rooms which are below the sewer level.
The pumps must not be used for pumping of liquids
containing great quantities of abrasive solids, like sand or
stones. Before the pumping of chemically aggressive liquids,
the resistance of the pump materials must be checked.
2.2. Product description
Smell-tight and watertight complete lifting station with one or
two pumps. The lifting station consists of a collecting tank
with all necessary ports for the connection of inlet pipe,
discharge pipe, air vent and manual diaphragm pump (see
page 19 - 21).
The controllers incorporate contactors, a pc-board with light-
emitting diodes (LEDs) for indication of operating condition
and a level switch which, via a hose, is operated by the
liquid level in the collecting tank.
The LEDs indicate :
- Pump operation
- Phase sequence fault (three-phase only)
- Fault
- Alarm
A thermal switch incorporated in the motor windings will
protect the motor from overheating by cutting off the supply
to the pump via the controller.
A back-up accumulator maintaining the alarm signal in case
of supply failure is available as an accessory. The
accumulator is fitted inside the controller via a plug and
ensures that an alarm can be given within 15 hours after the
electricity supply has been switched off.
The accumulator is fully charged on delivery. The charging
time is approx. 100 hours. The accumulator is automatically
charged when the electricity supply is switched on.
Note : Used up accumulators must be disposes of in
accordance with local regulations.
Three-phase controllers incorporate a phase monitoring
function which does not, however, prevent the motor from
starting in the event of wrong phase sequence of the mains
connection.
In addition to the LEDs, the controller front cover features:
- Function selector with the positions: 'Test' (manual
operation), 'Aus' (turn off) and 'Auto' (automatic
operation).
- On/off switch for built-in acoustic alarm.
SEKAMATIK 100 E single station
When the liquid level in the tank reaches the start level, the
pump will start and run until the stop level is reached.
If the liquid level rises to the alarm level, an alarm is given
until the liquid level is lowered below the alarm level.
SEKAMATIK 100/300 D twin station
The controller of SEKAMATIK 100/300 D automatically
ensures an even distribution of operating hours on both
pumps by changing the starting sequence after each pump
stop.
When the liquid level in the tank reaches the start level, one
pump is started. If the liquid level rises further, the other
pump is started as well. Both pumps will stop, when the
lowest stop level is reached.If the liquid level continues to
rise when both pumps are operating, an alarm is given until
the liquid level is lowered below the alarm level.
