As soon as the vacuum drops below or exceeds the set value
one suction system is switched on or off. This increases or
reduces the volume of suction flow.

1.7
1.5
1.3 Control line
Transfers the "on-off" signal to the suction system

systems from overheating.

1.5 Vacuum relief

1.6 Exhaust air line

1.1
1.7 Waste water line
Conducts the waste water to the drain system
1.4
1.8 Suction flow distributor
The suction flow distributor distributes the suction flow
evenly to the suction systems required.
8. Functional description:
After a suction hose on the hose system has been lifted or
when waste water emerges from the rinsing basins, a start
signal is sent to the control system via the suction contact
cable which starts all the suction systems at the same
time.
As soon as the nominal vacuum is reached, the system
automatically switches back to the operation of one or two
suction systems (depending on need).
The control unit constantly controls the vacuum in the pipe
system by switching the suction systems on or off, depending
on the amount of suction flow required.

The control unit receives the start signal via the suction contact cable which is connected to the terminals 1.8 This
start signal is transferred via the control lines, which are
likewise connected to the terminals 1.8 , to all the suction systems.
The nominal vacuum required has been preset at the vacuum
switches for suction system 2 1.5 and suction system 3
1.6 . As soon as this nominal vacuum has been reached, a
stop signal is sent via the vacuum switch to suction system 2
and suction system 3. In this situation, only suction system 1
is still in operation.
If, later on, a greater volume of suction flow is required (for
example when other vacuum consumers join the network),
the vacuum in the suction line network is reduced.
The vacuum switches detect this via the vacuum relief 1.12 .
So if the vacuum at the vacuum switch on suction system 2
1.5 falls below the minimum set point, suction system 2
automatically switches back on.
If this situation still does not produce the required suction
flow volume, the vacuum drops again. As soon as it falls
below the nominal minimum vacuum at the vacuum switch
for suction system 3 1.6 , suction system 3 switches on.
The system is then running at maximum power.
If the vacuum exceeds the maximum vacuum set for the
vacuum switch on suction system 3 1.6 , suction system
3 is switched off again. In this way the suction systems are
switched on and off in the sequence described.
In the event that no further start signals are sent via the
suction contact cable, all the suction systems switch off
automatically.

There is an adjusting screw on each of the two vacuum
switches, which can be used to adjust the vacuum level to
suit the condition of the suction line network. The various
suction line networks vary so greatly that it is not possible
to make a factory pre-setting for the vacuum switch.
If you turn a screw to the right, the nominal vacuum (at
which the suction system with switch on or off) on the
suction system concerned will increase. The switching
hysteresis is preset and cannot be altered.

Maintenance
Disposal of the equipment:
17. Maintenance:
For maintenance of the individual components on the suction systems please see the relevant Installation, Operation
and Maintenance Manual for the devices concerned.
Once the servicing work has been completed, check that
the non-return valve 1 has been correctly set and is
functioning properly.
18. Disposal of the equipment:
T he devices may be contaminated. Please
inform the disposal company of this so that the
necessary precautions can be taken.
Disposal of amalgam separator components,
such as sieves, filters, hoses etc., must also
comply with local regulations.
Uncontaminated plastic components of the suction system
may be re-cycled.
The built-in control unit, electronic circuit boards and components may be disposed of as electro-technical scrap.
Other metal components may be disposed of as ordinary
metal scrap.
If the devices is returned, for example to the dealer or
METASYS Medizintechnik GmbH, all connections must
be sealed so that they are water-tight.
