Pump Control (Twin station)
The control panel automatically ensures an even distribu-
tion 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 1,
one pump is started. If the liquid level rises further and
reaches the start level 2, the other pump is started as
well. This pump will run until its stop level is reached. The
operating pump 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.

3.4. Operation Conditions

Please pay attention to the installation and operation
instruction manual of the installed submersible pump.
3.5. Explosive Environments
For operation of the pumps in explosive environments
only models with explosion-proof motors (Ex model) must
be used.
For each individual installation the explosion classifi-
cation (Ex-class) of the pump must be approved by the
localauthorities.

4. Warranty

Our warranty only covers pumps which are installed and
operated in accordance with these installation and opera-
tion instructions and accepted codes of good practice and
being used for the applications mentioned in these in-
structions.

5. Transport and Storage

The pump station may be transported and stored in
vertical position. Make sure that it cannot roll or fall over.
For longer periods of storage, the pump should be pro-
tected against moisture, frost or heat.

6. Electrical Connection

6.1. General instructions

Before operation, an expert check must secure that
the required electrical protection measures exist. The
connection to ground, earthing, isolating transformer, fault
current breaker or fault voltags circuit must correspond to
the guidelines set forth by the responsible power plant.
The voltage required in the technical data sheet
must correspond to the existing line voltage.

Make sure that the electrical pin-and-socket connec-
tions are installed flood- and moisture-safe. Before start-
ing operation check the cable and the plug against dam-
ages.
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 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
[kg]
sure that the pumps of the pump station are suitable for
the electricity supply available at the installation site.

box. Controller for single-phase pumps also incorporate
66
the operating capacitors required.

The pump motors have a thermal switch incorporated in
the motor windings. The thermal switch protects the motor
71
from overheating by cutting off the supply to the pump via
113
the controller.
118
105 The electrical connection must be carried out in accor-
110
dance with the marking on the cable to the controller.
The lifting stations require no additional motor protection.
Connect the units to the mains supply.
An external fault signal device can be connected to the
controller via the potential-free fault signal output. Maxi-
mum load : AC 250 V, 5 A, AC 1.
• The installation place of the control panel should be
close to the pump station. Please pay attention to the
lenght of the power supply cable and the lenght of the
hose for the control panel.
• Do not install the pump station in explosive environ-
ments, even if you install explosion-proof pump motors.
• Mount the cable duct pipe.
• Mount the power supply.
• Mount the control panel on the pedestal.
• Pass through the cable duct pipe the power supply ca-
ble and hose for the control panel. Please pay attention
to the operating instructions and the wiring diagrams of
the control panel during installation.
• Carry out the earth leaking measure.

6.2. Electronic Control Box

The equipped electronic control box controls the operation
functions and announce failures which may be occure.
6.2.1. PS 1 (with 1 pump)
The function selector offers the following functions :
Operation switch
Position "Hand":
The pump operates, irrespective of the liquid level in the
tank.
Position "Off":
The pump is stopped. Furthermore the switch is used to
quit a failure before re-start of the unit.
Position "Auto":
Pump operation according to the liquid level in the tank.
Acoustic alarm switch
Position "On":
The built-in acoustic alarm is activated. Together with the
red LED "Alarm", the built-in acoustic alarm will start if the
