English
If the switchgear has been switched off by a protec-
tive device, it must not be switched on again until
the fault has been corrected.
Use of electronic devices such as soft starters or frequency
converters is not possible with this switchgear. Pumps must be
connected directly.
2.4.

Conduct during operation

When operating the switchgear, always follow the locally appli-
cable laws and regulations for work safety, accident prevention
and handling electrical products. To help to ensure safe working
practice, the responsibilities of employees should be clearly set
out by the operator. All personnel are responsible for ensuring that
regulations are observed.
Pushbuttons and LEDs on the housing are used to operate the
switchgear, display the operating state, and signal faults. The
housing cover must not be opened during operation.
DANGER due to electrical voltage
There is a risk of fatal electric shocks occurring
when performing work on the open switchgear.
only operate the switchgear with the cover closed!

Directives used

This switchgear is subject to:
• Various EC directives
• Various harmonized standards
• Various national standards.
See the EC Declaration of Conformity for precise details of the
guidelines and standards used.
Also, various national regulations are used as a basis for operat-
ing, installation and dismantling the switchgear. These include
the German accident prevention regulations, VDE regulations and
German Equipment Safety Law.

Product description

The switchgear has been manufactured with great care and is
subject to constant quality controls. Trouble-free operation is
guaranteed if it is installed and maintained correctly.

intended use and fields of application

DANGER of explosions!
If the connected pump and signal transmitter are
used in potentially explosive areas, there is a dan-
ger of fatal injuries from explosions! the connected
pump and signal transmitter must always be used
outside of potentially explosive areas. Installation
must always be carried out by a qualified electri-
cian.
The MS-Lift switchgear is designed for
• automatic control of 1 pump without approval for poten-
tially explosive areas in lifting units and sewage shafts for
delivery of water/sewage.
The switchgear must not
• be used in potentially explosive areas.
• be overflowed.
Intended use also includes observation of these instructions. Any
other use is regarded as non-compliant with the intended use.
NOTE
For automatic control, float switches must be provid-
ed by the customer.

How it works

The microcontroller-controlled Easy Control switchgear is
designed for control of a pump with a fixed speed capable of lev-
el-dependent switching.
Level detection is via two-position control with a float switch,
which needs to be provided by the customer. The pump is acti-
vated/deactivated automatically depending on the fill level. If a
follow-up time is required, this can be set via a potentiometer.
On reaching high-water level (detected via a separate float
switch), a visual and audible warning is emitted and forced switch-
on of the pump takes place. The collective fault signal (SSM) is
active.
The current operating state is indicated via LEDs on the front side.
Operation is via 4 pushbuttons on a control panel attached at the
side.
Faults are indicated visually via LEDs and audibly via an integrated
buzzer. The last error is stored in the fault memory.
