ENGLISH
For AD 25-AD 910 only. The reset function of the overcurrent
relay must be set to “Hand”. If necessary, use a screwdriver
to turn the reset button clockwise, as far as it will go, to the
“H” position.
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 conti-
nuous contact sensors.
Examples: Air diaphragm control unit, static air level con-
trol, hydrostatic level contact sensors or float switch.
Connection of the continuous contact sensors:
•
Base load ON-OFF Terminal 21 / 23
•
High water alarm Terminal 27 / 28
If a separate OFF float switch is connected
– Base load ON
Terminal 21 / 22
– Pump OFF
Terminal 22 / 23
– High water alarm Terminal 27 / 28

Shutting down the internal alarm buzzer
Remove the sealed jumper "BRX" near the buzzer. To pre-
vent the jumper from getting lost, plug it onto a pin of 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 po-
larity.
Remote failure indication system
Connect the remote system to terminals 40/41 on the PCB.
The potential-free NO contact of the centralised alarm can
be loaded with a maximum of 5 A / 250 VAC.
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 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 manufactu-
rer! If dry-cell batteries or Lithium batteries are used there
is a danger of explosion!
Fitting the LCD time meter (accessory)
The positions on the printed circuit board is marked "Time
meter". Shorten the connecting 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 prin-
ted 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-independent
alarm, it must be checked at regular intervals. For this pur-
pose de-energise the control unit and trigger the alarm (by
triggering the motor protection relay, for example). The
pitch and volume of the buzzer must not change signifi
-
cantly for several minutes - otherwise replace the batte-
ry pack. Battery packs which are more than five years old
should be replaced as a precautionary measure.
