Connecting the level contact sensor
The level contact sensor is connected to the control unit on
site in accordance with the circuit diagram (appendix).
The switch-off point is set in the factory. The switch-on
point must be set for each individual lifting station. The other
switching points for the alarm (+2 cm) and peak load (+4 cm) are
then automatically set accordingly by the control unit.
Setting the switch-on level
Set the Hand-Off-Automatic selector to “0”. Adjust the switch-
on point in the “analogue evaluator” module on the right-hand
side of the control unit. Temporarily remove the transparent
cover of the module. Fill the collecting tank with water up to
the desired switch-on level (but not higher than the lower edge
of the inlet pipe).
There are three LEDs on the analogue evaluator labelled P1 -
P2 - P3. Only P2 must light up. If P3 lights up too, a readjust-
ment must be carried out.
Turn the small setscrew below P1 one or two revolutions in a
clockwise direction. Now immerse the level controller float in
the tank until it is below the switch-off point and then allow
it to float up again. If P3 is still lit up, turn the setscrew a fur -
ther revolution in a clockwise direction and immerse the float
again.
Repeat this procedure until P3 no longer lights up, then turn
the setscrew back carefully in an anti-clockwise direction until
P3 only just lights up. The switch-on point is now set.
Alarm system
Malfunction messages are given both visually as well as acous-
tically. The standard mains-dependent alarm system indicates
motor faults in the pump (red LED). At the same time a built-in
acoustic alarm sounds. This acoustic signal can only be turned
off by remedying the fault or by totally deactivating it.
If an acoustic signal would be inappropriate at the installation
site in question, an alarm signal can be relayed via the poten-
tial-free contact (terminals 40 and 41) on the circuit board. The
connection cable must have maximum length of 250m for a
cross-section of 0.75 mm². The potential-free NO contact of
the centralised alarm can be loaded with a maximum of 5A /
250 VAC. The contact opens after the fault has been remedied.
Battery pack for alarm system (accessory)
The alarm device is mains-dependent in its standard version,
i.e. it is not possible to trigger a high-water alarm in the event
of a power failure. To enable the alarm device to work even if
there is a power failure, a rechargeable battery must be used.
Open the transparent cover. Connect the battery to the con-
nection clip, and use the existing cable tie to attach it to the
intended position on the PCB. The battery can supply the alarm
system with power for a continuous alarm of about 1 hour.
After the return of the mains voltage, the battery is charged
again automatically. An empty battery is ready for operation
within approx. 24 hours. It is fully charged after about 100
hours.
Check the function of the battery at regular intervals! To do so,
disconnect the lifting station from the mains power supply and
trigger a high-water alarm. The volume of the acoustic signal
must not become significantly quieter over a period of several
minutes. The service life is about 5 years. Note the insertion
date on the battery, and after five years the battery 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!
Time meter (accessory)
An optional time meter can be fitted in the control unit. To fit
this, shorten the connections of the time meter to approx. 8
mm and insert them in the four sockets at location A2 on the
printed circuit board. If the time meter indicator does not go
on after switching the lifting station on again, rotate the time
meter through 180°.
Shutting down the internal alarm buzzer
Remove the sealed jumper (BRX). To prevent the jumper from
getting lost, re-attach it to a pin on the two-pole pin connector.
External alarm buzzer
Open the transparent cover on the control unit.
An additional separate acoustic 12 VDC signal transmitter with
an input current of not more than 30 mA can be connected to
terminals “S+” and “S-”. The internal alarm buzzer can either be
switched on or off.
Test run and functional check
NOTICE! First of all tighten all clamps and flanged connections.
1. Open the maintenance cover on the tank.
2. Open the sluice valves in the inlet pipe and pressure pipe.
3. Connect the lifting station to the power supply and observe
the indicator for the rotating field direction.
4. Fill the tank up to the switch-on level.
5. The pump will now switch on and empty the tank. Observe
the pumping process through the maintenance opening.
6. Lift the float of the level controller slowly by hand until it is
above the switch-on point and hold it there until the alarm
is triggered
7. Then close the maintenance opening with the cover and
seal.
8. Check to ensure that the tank, fittings and pipes are water -
tight, by carrying out several switching runs.
OPERATION
Automatic operation is the normal operating mode of the lift-
ing station. The rocker switch must be set to “Automatic”. The
integrated level controller switches the pump on and off de-
pending on the water level in the tank. A green LED lights up
when the pump is operating.
NOTICE! If unusually large quantities of wastewater flow into
the lifting station (e.g. when a pool is drained), partially close
the sluice valve at the inlet until the lifting station can opera-
te normally again, switching on and off, (not pumping conti-
nuously, since this could overheat the pump motor).
Emergency operation with one pump
If maintenance valves are fitted between the pump and the
tank, the lifting station can be temporarily operated with only
one pump.
Set the rocker switch for the faulty pump to “0” on the control
unit and close the maintenance valve.
