Level contact sensors (accessory)
The levels in the collecting chamber are detected
by continuous contact sensors.
Examples: Air diaphragm control unit, static air
level control, hydrostatic level contact sensors or
float switch.
Connection of the continuous contact sensors:
• Base load ON-OFF Terminal 21 / 23
• Peak load ON-OFF Terminal 24 / 25
• High water alarm Terminal 27 / 28
If a separate OFF float switch is connected
ū Base load ON Terminal 21 / 22
ū Pump(s) OFF Terminal 22 / 23
ū Peak load ON Terminal 24 / 25
ū High water alarm Terminal 27 / 28
GL= base load · SL= peak load
Alarm= High water alarm
For duplex units: Normal operation with peak-
load function
The micro-switch S8 is used to determine which
pump is switched on in the event of high water
alarm; "GL" for the base load pump or "SL" for the
peak load pump.
For duplex units: Operation without peak-load
function (no parallel pump operation)
Do not connect the "Peak load" float switch, or,
if already connected, disconnect it from terminal
24/25.
The micro-switch S8 must be set to "GL". The pump
lock (S7) must be set to "ON".
In the event of a motor fault, the control unit will
automatically switch to the standby pump (not BD
00 or BD 00E).
For duplex units: Operation as a single pump
unit
The control unit can also be operated with only
one pump connected. For this purpose, use an
insulated core to bridge terminals 30/32 for the
pump that is not connected. Both motor protec-
tion switches must be switched on.
Set the selector switch of the unconnected pump
to position "0" and of the connected pump to po-
sition "Automatik".
Shutting down the internal alarm buzzer
Remove the sealed jumper "BRX" near the buzzer.
To prevent the jumper from getting lost, plug it
onto a pin of the two-pole pin connector.
External alarm buzzer (accessory)
ATTENTION! When an external buzzer is connec-
ted, the integrated buzzer must be shut down.
A 12V buzzer with a max. current consumption of
30 mA can be connected to terminals "S+" and "S-"
with the correct polarity.
Remote failure indication system
Connect the remote system to terminals 40/41 on
the PCB. The potential-free NO contact of the cen-
tralised alarm can be loaded with a maximum of
5 A / 250 VAC.
External 230V~ flashing light or warning light
(BD accessory)
Connect a 230V~ lamp (1 A max.) to terminals N
and 43.
Lay an insulated wire bridge from terminal U~ to
terminal 42. The electric circuit is protected by F1.
Set "Alarm signal" micro-switch as follows:
Flashing light: Position "Permanent" (Continuous)
( = )
Warning light: Position "Flashing" (Blinkend)

Battery pack for off the line operation of the
alarm system (accessory)
Connect the battery pack to the connection clip,
and use the existing cable ties to attach to the in-
tended position on the PCB.
An empty battery is ready for operation within ap-
prox. 24 hours. It is fully charged after about 100
hours.
ATTENTION! Check the function of the battery
pack at regular intervals! The service life is about 5
to 10 years. Note the insertion date on the battery
pack and after five years the battery pack should
be replaced as a precautionary measure.
Only use the 9 volt battery supplied by
the manufacturer! If dry-cell batteries
are used there is a danger of explosion!
Fitting the LCD time meter (accessory)
The positions on the printed circuit board for each
pump are marked "Time meter". Shorten the con-
necting wires of the time meter to approx. 10 mm
and insert them in the printed circuit board. The
connecting wires and also the connectors on the
printed circuit board are marked "N-P-I-R".
After the mains voltage has been re-connected,
the LCD should be visible. If no display appears,
switch the mains voltage off again, disconnect the
time meter and turn it through 180 degrees before
reconnecting it.

Maintenance
The control unit is maintenance-free. Depending
on the quality of the wastewater, the level contact
sensors must be checked at regular intervals, and
any deposits must be removed!
If a 9V battery pack is connected for a mains-inde-
pendent alarm, it must be checked at regular inter-
vals. For this purpose de-energise the control unit
and trigger the alarm (by triggering the motor pro-
tection switch, for example). The pitch and volume
of the buzzer must not change significantly for se-
veral minutes - otherwise replace the battery pack.
Battery packs which are more than five years old
should be replaced as a precautionary measure.
