Safety instructions
This instruction manual contains essential in -
formation that must be observed during instal -
lation, operation and servicing. It is therefore
important that the installer and the responsi -
ble technician/operator read this instruction
manual before the equipment is installed and
put into operation. The manual must always be
available at the location where the pump or the
plant is installed.
Failure to observe the safety instructions can
lead to the loss of all indemnity.
Labelling of instructions
In this instruction manual, safety information is
distinctly labelled with particular symbols. Dis -
regarding this information can be dangerous.

Danger to equipment and operation
Qualification and training of personnel
All personnel involved with the operation, serv -
icing, inspection and installation of the equip -
ment must be suitably qualified for this work
and must have studied the instruction manual
in depth to ensure that they are sufficiently
conversant with its contents. The supervision,
competence and areas of responsibility of
the personnel must be precisely regulated by

Safety-conscious working
The safety instructions in this instruction man -
ual, the existing national regulations regarding
accident prevention, and any internal working,
operating and safety regulations must be ad -
hered to.
Safety instructions for the operator/user
All legal regulations, local directives and safety
regulations must be adhered to.
The possibility of danger due to electrical en -
ergy must be prevented.
Leakages of dangerous (e.g. explosive, toxic,
hot) substances must be discharged such that
no danger to people or the environment oc -

Safety instructions for installation, inspec-
tion and maintenance works
As a basic principle, works may only be carried
out to the equipment when it is shut down.
Pumps or plant that convey harmful substanc -
es must be decontaminated.
All safety and protection components must be
re-fitted and/or made operational immediately
after the works have been completed. Their ef -
fectiveness must be checked before restarting,
taking into account the current regulations and
stipulations.
Unauthorised modifications, manufacture
of spare parts
The equipment may only be modified or al -
tered in agreement with the manufacturer. The
use of original spare parts and accessories ap -
proved by the manufacturer is important for
safety reasons. The use of other parts can result
in liability for consequential damage being re -
scinded.
Unauthorised operating methods
The operational safety of the supplied equip -
ment is only guaranteed if the equipment is
used for its intended purpose. The limiting val -
ues given in the "Technical Data" section may
not be exceeded under any circumstances.
Instructions regarding accident prevention
Before commencing servicing or maintenance
works, cordon off the working area and check
that the lifting gear is in perfect condition.
Never work alone. Always wear a hard hat, safe -
ty glasses and safety shoes and, if necessary, a
suitable safety belt.
Before carrying out welding works or using
electrical devices, check to ensure there is no
danger of explosion.
People working in wastewater systems must
be vaccinated against the pathogens that may
be found there. For the sake of your health, be
sure to pay meticulous attention to cleanliness
wherever you are working.
Make sure that there are no toxic gases in the
working area.
Observe the health and safety at work regu -
lations and make sure that a first-aid kit is to
hand.
In some cases, the pump and the pumping me -
dium may be hot and could cause burns.
For installations in areas subject to explosion
hazards, special regulations apply!

Description
Electronic control unit for level control of one
(AD) or two (BD) d.o.l. starting explosion-pro -
tected submersible pump(s).
This control unit meets ATEX requirements for
level detection monitoring and limitation of
motor temperature and pump run-time.
The control unit incorporates mains-depend -
ent LED failure indicators and an acknowl -
edgeable alarm buzzer to indicate faults. Two
potential-free centralised alarm contacts can
be used as additional remote failure indica -
tors. An optional 9V rechargeable battery can
also be fitted to sustain an alarm facility even if
a power cut occurs. The battery pack can sup -
