Note on BD 00. The motor protection switch only protects
against a short-circuit in the pump. The current at the motor
protection switch must therefore be adjusted to the maximum
setting.
If the direction of rotation is correct, the starting jerk of the
pump is counter to the direction of rotation arrow on the motor
housing. If the direction of rotation is wrong, two phases of the
pump cable must be interchanged on the control unit.
CAUTION!
The start-up jolt can be very forceful.
Level contact sensors (accessory)
The levels in the collecting chamber are detected by continu-
ous 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
• Pump(s) OFF
Terminal 21 / 22
• Base load ON
Terminal 22 / 23
• Peak load ON
Terminal 24 / 25
• High water alarm Terminal 27 / 28
GL= base load · SL= peak load · Alarm= High water alarm
Operation with peak-load function
If a high water alarm is activated, additional switch-on com-
mands are given:
• or the base load pump (jumper BRX3 at GL) or
• for both pumps (jumper BRX3 at SL)
Operation without peak-load function (no parallel pump oper-
ation)
Do not connect the "Peak load" float switch, or, if already con-
nected, disconnect it from terminal 24/25.
Jumper BRX3 must be set to "GL".
In the event of a motor fault, the control unit will automatically
switch to the standby pump (not BD 00E).
Operation as a single pump unit
The control unit can also be operated with only one pump con-
nected. Both motor protection switches must be switched on
(not for BD 00E).
Set the selector switch of the unconnected pump to position
"0" and of the connected pump to position "Automatik".
Internal alarm buzzer shutting down
The internal alarm can be shut down. To do so, remove jump-
er "BRX1" near the buzzer. To prevent the jumper from getting
lost, re-attach it to a pin on the two-pole pin connector.
External alarm buzzer (accessory)
Notice! When an external buzzer is connected, 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 can be loaded with a maximum of 5 A
/ 250 VAC.
External 230V~ flashing light or warning light
(accessory)
Connect a 230V~ lamp (1 A max.) to terminals N and 41.
Lay an insulated wire bridge from terminal U~ to terminal 40.
The electric circuit is protected by F1.
Set Jumper BRX2 as follows:
Flashing light without BRX2 (Continuous ===)
Warning light with BRX2 (Flashing (_Π_Π_ )
Battery pack for off the line operation of the
alarm system (accessory)
Connect the battery pack to the connection clip, and use the ex-
isting cable ties to attach to the intended position on the PCB.
An empty battery is ready for operation within approx. 24
hours. It is fully charged after about 100 hours.
NOTICE! Check the function of the battery pack at regular in-
tervals! The service life is about 5 to 10 years. Note the inser-
tion date on the battery pack and after five years the battery
pack should be replaced as a precautionary measure.
CAUTION!
Only use the 9V-NiMh battery supplied by the manufacturer! If
dry-cell batteries or Lithium batteries are used there is a dan-
ger of explosion!
Fitting the LCD time meter (accessory)
The positions on the printed circuit board for each pump
are marked "BSZ". Shorten the connecting wires of the
time meter to approx. 10 mm and insert them in the print-
ed circuit board. The connecting wires and also the con-
nectors 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 volt-
age 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-independent
alarm, it must be checked at regular intervals. For this purpose
de-energise the control unit and trigger the alarm (by trigger-
ing the motor protection switch, for example). The pitch and
volume of the buzzer must not change significantly for several
minutes - otherwise replace the battery pack. Battery packs
which are more than five years old should be replaced as a pre-
cautionary measure.
