1.2 Application
The Airtrol is an automatic cleaning, pH signal
monitoring and calibration system.
When used in conjunction with the retractable
pH / redox assembly Probfit, the Airtrol
permits automatic cleaning and calibration of
pH electrodes.
These operating instructions describe the
automatic cleaning, pH signal monitoring and
calibration system of the Airtrol CPC 200 / 210.
Note:
Separate operating instructions
are required for the built-in pH
measuring transmitter Mycom

3.4 Compressed air
connection
The compressed air is supplied via an
ID4 / OD6 hose (4 mm inside diameter,
6 mm outside diameter).
The compressed air is to be supplied to the
pneumatic unit CPC 210 via a line with a large
diameter.
•Air quality: filtered (5 µm),
water and oil-free
•Air pressure: 4 to 6 bar
•Air flow
requirement: max. 20 l/min
Note:
•Compressed air pressures below
4 bar produce the error message
“Air pressure too low”.
•Please note the applicable
regulations for accident prevention
and safety for compressed air
systems.
•We recommend installing a
stopcock close to the
compressed air connection.
3.5 Water connection
Screw-type couplings (SERTO system) are
used for the water connections (both hoses
and pipes with an inside diameter of 4 mm
and an outside diameter of 6 mm).
•Water quality: city water,
free of solid particles
•Water pressure: 4 to 6 bar
Note:
•Water pressures below 4 bar
will produce the error message
“Water pressure too low”.
•We recommend installing a
stopcock close to the water
connection.
3.6 Buffer and cleaner
solutions
The suction lines for the buffer and cleaning
solutions go through the cabinet floor directly
into the buffer and cleaner solution bottles
screwed onto the cabinet.
The suction hoses can be extended if larger
buffer and cleaning solution containers are to
be used.
The suction height of the pumps is max. 1.5 m.
Warning:
Mechanical shocks on the buffer
and cleaner solution bottles or
horizontal position of the cabinet
may cause penetration of fluid.
3.7 Connection to
retractable pH assembly
•Connect the pneumatic hoses 1 to 9 to the
retractable pH assembly Probfit CPA in
accordance with the pneumatic connection
diagram (see fig. 3.5).
Also refer to the operating instructions for
the retractable pH assembly.
•The connections for rinse air, buffer, cleaning
agent and rinse water are connected on the
assembly.
•Plug in the multiple hose coupling when
connecting the pneumatic unit CPC 210
and lock the closure in the “Lock” position.

4. Electrical connection
4.1 Basics for connection
Caution:
•The unit must be grounded before
start-up!
•If faults cannot be remedied, the
unit must be removed from service
and secured to prevent accidental
start-up.
•Before carrying out any installation
or maintenance work, the system
is to be shut down and the pressure
in the hoses is to be released, i. e.
set the main switch to OFF and
shut off the media (caution: hoses
may contain cleaner solution!).
Warning:
•The notes and warnings in these
operating instructions must be
strictly adhered to!
•Maintenance work may only be
carried out by qualified personnel
if the unit remains energised!
•Local power supply company
regulations are to be observed!
•Use conductor cross sections in
accordance with VDE 0100!
•Retighten all screw terminals
before starting up the system!
Note:
•This system has been built
and tested in accordance with
VDE 0660 T500 and left the
manufacturer’s works in perfect
condition.
•Any faults in the system may be
remedied with the aid of the error
list in chapter 7.1.
•Interventions in or changes to the
system are impermissible and will
void the warranty.
•After installing and connecting the
system and assemblies, the entire
system should be checked for
proper function.

4.3 Connection of
CPC 200 to CPC 210
The operating unit CPC 200 is connected to
the pneumatic unit CPC 210 by means of a
14-wire cable.
4.3.1 Connection type selection
for pH transmitter
Mycom CPM 151-P
•When a retractable Probfit assembly
made of PVC or PVDF material is used,
the asymmetrical high-impedance type
of connection must be chosen on the
measuring transmitter.
•When a retractable Probfit assembly made
of 1.4571 material is used, the symmetrical
high-impedance type of connection must be
chosen on the measuring transmitter and an
additional connected potential matching.
Note:
Please note the separate operating
instructions for the pH measuring
transmitter Mycom CPM 151-P and
the retractable pH assembly Probfit.
4.4 Connective networking
of several systems
via Profibus
A maximum of 10 systems, each comprising
one control unit CPC 200 and one pneumatic
unit CPC 210, can be connected via Profibus.
Shielded twisted-pair bus cable is used for
bus system wiring (for properties see table in
chapter 9). The bus connectors are installed
in the PLC at the factory.
Procedure
•Route and split the bus cable as required.
•Connect the bus cable.
•Enable the terminating resistor on the first
and last stations by switching it to the “ON”
position.
•Plug in the bus connectors.
Bus cable connection
•Strip the wires according to fig. 4.2.
•Connect the bus cable.
Always connect through
A – A – A … and
B – B – B …
•Connect the bare screen to the metal guide.

Note:
Do not twist, stretch or pinch the
cables during routing.
Warning:
When routing lines outside buildings,
the applicable lightning protection
and grounding measures must be
taken.
•Lines outside buildings are to be run
– in metal pipes grounded on both
sides, or
– in concrete armouring
•Signal lines are to be protected
against overvoltage by
– varistors, or
– inert gas-filled lightning arresters
•Install these protective devices
where the cable enters the building.

5. Start-up
5.1 General
Note:
•The applicable regulations for
safety and accident prevention
must be observed.
•Prior to power-up, verify that the
mains ratings match the ratings
on the nameplate.
•Make sure the media – air and
water – are available (stopcocks
open).
•The electrode must be installed in
the assembly, and the measuring
cable must be connected.
•The hoses for air and liquid media
must be connected to the assembly.
•The multiple hose coupling in the
pneumatic connecting line must
be in the “LOCK” position.
•The bottles are filled with the buffer
solutions and cleaning agent.
•Switch on the PLC:
The switch must be set to “RUN”
(LED RUN is on).
Warning:
•Prior to performing installation or
repair work, release air and water
pressure from system sections.
•Do not perform installation or
maintenance work while the
system is energised.
•Please be aware that the hoses
may contain caustic cleaner
solutions.
5.2 Start-up sequence
Note:
•The following steps must be taken
before starting up the Airtrol.
•Refer to chapter 6 for a detailed
listing of the parameter setting
steps.
•Refer to the following tables for a
listing of the factory settings.

Remark:
1Toggle cleaning system
0 = Internal cleaning system
1 = External cleaning system
2Switch on back-pressure water
When the pH electrode is retracted
or moved into the process, a
short-time overlap between process
and outlet occurs with some
retractable assemblies, e. g. Probfit
CPA 463. To prevent intrusion of
fibrous or abrasive media into the
seal and rinse area of the assembly,
back-pressure water can be
switched on when the assembly is
retracted or moved into the process.
An additional outlet valve
(accessory for the assembly)
ensures that the back-pressure
does not escape through the outlet.
Note:
The back-pressure must exceed the
process pressure.
