3.2 Function
Sampling takes place in four steps:
123 4
A0022647
1. Blow clear
 The vacuum pump blows the suction line clear via the dosing system.
2. Intake
 The "Airmanager" (pneumatic control unit) switches the air path of the vacuum
pump to "intake". The sample is drawn into the dosing beaker until it reaches the
conductivity probes of the dosing system.
3. Dose
 The intake process ends. Depending on the position of the dosing tube (item D), the
excess sample liquid flows back to the sampling point.
4. Drain
 The hose clamp is opened and the sample is drained into the sample bottle.
3.3 Dosing system
The sample liquid is extracted discontinuously by a vacuum system. The vacuum system in the
ASP Station 2000 RPS20B consists of the following components:
• Vacuum membrane pump
• Non-wearing, “Airmanager” pneumatic step control unit
• Dosing system

2 Conductivity sensor (long)
3 Conductivity sensor (long)
4 Dosing tube
Level detection principle
Three conductivity sensors are located in the cover of the dosing chamber (→  3,  10).
During the intake process, the sample liquid first reaches the longer sensors, items 2 and 3.
The system thus detects that the dosing chamber is filled and the intake process is ended.
Should sensors 2 and 3 fail, safety shutdown takes place via the shorter conductivity sensor,
item 1.
The sampling volume is set by adjusting the dosing tube (item 4) between 20 ml and 200 ml.
The dosing system can be dismantled easily - no tools are needed - and cleaned.
3.4 Sample distribution
The sample liquid is distributed into the individual bottles by a distribution arm (item A). In
addition to a 30 l and 60 l composite container, different bottle configurations are also
available. The distribution versions can be changed or replaced easily without the need for
special tools. The ASP Station 2000 enables the flexible configuration of sample distribution.
Users can define individual bottles and bottle groups as they wish for the main, switchover
and event programs. Individual bottles can be found in two separate bottle trays (item C).
Grips on the bottle trays make transportation easy and practical.

3.5 Sample preservation
The sample bottles are located in the wet compartment of the sampler. The sample
compartment temperature can be set between +2 and +20 °C (36 to 68 °F) directly at the
controller (factory setting: +4 °C (39 °F)). The current sample compartment temperature is
displayed at the controller. The evaporator and the defrost heater are embedded in the PU
insulation behind the inner lining to protect them against corrosion and damage. The
compressor and the condenser are located in the upper section of the sampler.
All parts that transport medium (e.g. distribution arm, dosing system, distribution pans) can
be disassembled and cleaned easily without the need for tools. The entire sample
compartment is fitted with a seamless plastic inner lining for easy and effective cleaning.

Note the following when erecting the device:
• Always route the suction line so that it slopes upwards from the sampling point to the
sampler.
• The sampler must be located above the sampling point.
• Avoid siphoning effects in the suction line.
Requirements for the sampling point:
• Do not connect the suction line to pressurized systems.
• Use the suction filter to impede coarse and abrasive solids and solids which can cause
clogging.
• Immerse the suction line in the direction of flow.
• Take the sample at a representative point (turbulent flow, not directly at the bottom of the
channel).
Useful sampling accessories
• Suction filter:
Impedes coarser solids and solids which can cause clogging.
• Immersion assembly:
The adjustable immersion assembly fixes the suction line at the sampling point.
5.2 Installation

V1 Diaphragm valve
V2 Ball valve
3 Flow assembly
Use diaphragm valve 1 to set the flow rate to a
maximum of 1000 l/h to 1500 l/h. When the
sampling cycle begins, one of the relay outputs can
be used to control and open ball valve 2. The
medium flows through the pipe and the flow
assembly and into the outflow. Once an adjustable
delay time has elapsed, the sample is taken directly
from the flow assembly. Ball valve 2 is closed again
once the sample has been taken.
The ball valve and the diaphragm valve are
not included in the scope of supply. If
necessary, please request a quote from your
Endress+Hauser sales center.
5.4 Post-installation check
1. Verify that the suction line is securely connected to the device.
2. Visually check that the suction line is installed correctly from the sampling point to the
