Unauthorised operating methods
The operational safety of the supplied equipment is only guar-
anteed if the equipment is used for its intended purpose. The
limiting values 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, safety 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 regulations and make
sure that a first-aid kit is to hand.
In some cases, the pump and the pumping medium 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 two d.o.l. starting
submersible pumps.
Up to four level contact sensors can be connected.
For duplex pump units the power-up sequence of pump 1 and
pump 2 alternates automatically after every base-load pump-
ing process. The resting pump is switched on in the event of
high water or a pump fault.
Duplex units can be operated optionally without peak-load
function (i.e. no parallel pump operation). Automatic switch-
over to the standby pump will occur in the event of failure.
The control unit incorporates mains-dependent LED failure
indicators and an alarm buzzer to indicate faults. One poten-
tial-free centralised alarm contact can be used as an addition-
al remote failure indicator. An optional 9V rechargeable battery
can also be fitted to sustain an alarm facility even if a power
cut occurs. The battery pack can supply the alarm system with
power for about one hour of continuous use.
EMC
Our standard submersible pumps and accessories when in-
stalled as specified and used as intended meet the protective
requirements of the EMC Directive, and is suitable for use in
domestic and commercial areas of the public power supply
network. When connected to an industrial mains supply in an
industrial plant with the power supply provided by a compa-
ny-owned high-voltage transformer, it is to be expected that
there will be insufficient immunity to interference.
OPERATION
NOTICE! Operate the control in dry rooms only and keep the
housing closed at all times.
Automatic operation
Automatic operation is the normal operating mode of the unit.
The Manual-0-Automatic selector switch for the pumps must
be set to the "Automatik" position for this operating mode. The
pumps are switched on and off again automatically depending
on the wastewater level in the collecting chamber. The green
"Betrieb Pumpe" (Pump operation) indicator lights up when the
pumps are operating.
Manual operation
In case of a malfunction in automatic operation, the collecting
chamber can be drained manually as well. For this action, set
the selector switch to the "Hand" (Manual) position. The pump
will now operate continuously and independently of the waste-
water level.
NOTICE! If the "Hand" (Manual) setting is actuated for too long
at a time, the pump may draw in air. Certain pump types need
to be vented in this case, since they would not pump otherwise.
Shutting down the pump
Set the rocker switch to "0". The pump is shut down. In duplex
units the remaining pump continues to work in automatic op-
eration.
