4.2.5 Rinse connections
The service chamber connections of the sterile CPA875 retractable assembly make it
possible to clean the chamber and the sensor with water or a cleaning solution at a
pressure of 6 bar (87 psi) max. or to sterilize it with steam (SIP).
The retractable assembly can be selected with a single- or double-chamber system. If the
double-chamber system is used, all four connections must be connected to inlet and outlet
pipes.
Seals can be damaged if the water pressure is too high.
Install an pressure-reducing valve upstream if there is a possibility that the water
pressure will increase to more than 6 bar (87 psi) (including any short pressure
surges).

pressure compensation measures are required here):
• Depending on the cleaning method, cleaning agent and purge gas are supplied via the
inlet (1).
• These media are removed via the outlet (2).
In the "Move from service position to measuring position" state (B), the pressure conditions
in the service chamber must be balanced when moving. The inlet and outlet of the service
chamber are assigned as follows:
• The air is removed via the inlet (1) (inlet is open).
• The air is supplied via the outlet (2).
In the "Move from measuring position to service position" state (C), the pressure conditions
in the service chamber must be balanced when moving. The inlet and outlet of the service
chamber are assigned as follows:
• The air is supplied via the inlet (1).
• The air is removed via the outlet (2) (outlet is open).
The drive must be controlled simultaneously with the control of the inlets and outlets
of the "inner service chamber".
The controller for the inlets, outlets and the drive is installed at the place of
installation. It is not included in the delivery for the assembly.
4.2.7 Connecting the limit position switches
With limit position detection, you can notify a system located downstream (transmitter,
switching amplifier, output interface terminal) whether the assembly is in the
measurement or service position(in the case of a manual drive, only the measurement
position is queried).
The assembly can be ordered directly with limit position detection, or it can be retrofitted
at a later stage.
Switching element function: NAMUR NC contact (inductive)
Switching distance: 1.5 mm (0.06 ")

6 Maintenance
WARNING
L
Risk of injury if medium escapes
Before each maintenance task, ensure that the process pipe is empty and rinsed.
‣
Move the assembly to the "Service" position.
‣
The assembly drive is maintenance-free. It is not possible to carry out maintenance or
repair work on the drive.
6.1 Maintenance intervals
The specified intervals serve as a guide. For harsh process or ambient conditions, it is
recommended that the intervals be reduced accordingly. Cleaning intervals for the
sensor and assembly are dependent on the medium.
Interval Maintenance measures
Monthly
or after 500 strokes (whatever comes
first)
Biannually
or after 5000 strokes (whichever comes
first)
Biannually
or after 5000 strokes (whichever comes
first)
Check the following for leaks:
• rinse lines
• process connection
• compressed air hoses (pneumatic version).
Does medium escape from the leakage hole when the assembly is
moving? This may indicate that the internal O-rings in the service
chamber are defective or that the immersion tube O-rings in the
double-chamber assembly are defective.
Check the leakage hole in the service chamber.
‣
1. Remove the sensor and check the sensor for deposits.
2. If deposits are present, check the cleaning cycle (cleaning
agents, temperature, duration, flow volume).
When process pressure is applied and the rinse lines are detached,
there should be no discharge of medium from the assembly's rinse
connections.
Check for defective process seal(s).
‣
In addition:
Replace the seals that are in contact with medium.
‣
1. Check the locking mechanism is not blocked.
2. Remove the sensor.
The contact surface of the sensor in the assembly is
spring-loaded and must be free to move.
Possible cause of failure: Contamination inside the drive, e.g. caused
by a broken sensor.
32 Endress+Hauser
Page 33
Cleanfit CPA875 Maintenance
6.2 Cleaning the assembly
To ensure stable and reliable measurements, the assembly and the sensor must be cleaned
regularly. The frequency and intensity of the cleaning process depend on the medium.
6.2.1 Manually operated assembly
All parts in contact with the medium, such as the sensor and the sensor guide, must be
cleaned regularly. To do so, remove the sensor
• Remove light dirt and fouling with suitable cleaning solutions. (→ 34)
• High levels of contamination are removed using a soft brush and a suitable cleaning
agent.
• For very persistent dirt, soak the parts in a cleaning solution. Then clean the parts with a
brush.
A typical example of a cleaning interval would be 6 months in the case of drinking
water.
1)
.
6.2.2 Pneumatically controlled assembly
Regular, pneumatically controlled cleaning is possible using the rinse water connection
and the appropriate equipment.
6.3 Cleaning the sensor
Clean the ORP electrodes mechanically only and always use water. Never clean with
‣
chemical cleaning agents. Such cleaning agents cause a potential to build up at the
electrode which takes a few hours to dissipate. The potential causes errors in the
measurement.
Do not use abrasive cleaners. These can cause irreparable damage to the sensor.
‣
Where necessary, perform a new calibration following the cleaning process.
‣
You must clean the sensor:
• Before every calibration
• Regularly during operation
• Before returning it for repairs
You can remove the sensor and clean it manually, or you can clean it in automatic mode
using the rinse water connection.
2)
1) same as sensor installation, but in reverse order
2) only if the assembly is fitted out accordingly
Endress+Hauser 33
Page 34
Maintenance Cleanfit CPA875
6.4 Cleaning agent
The choice of cleaning agent depends on the degree and type of contamination. The most
common types of contamination and the appropriate cleaning agents can be found in the
following table.
Type of soiling Cleaning agent
Greases and oils Hot water or tempered, surfactant-containing (alkaline)
media
1)
or water-soluble, organic solvents (e.g.
ethanol)
Limescale deposits, metal
Approx. 3% hydrochloric acid
hydroxide buildup, lyophobic
biological buildup
Sulfide deposits Mixture of 3% hydrochloric acid and thiocarbamide
(commercially available)
Protein buildup Mixture of 3% hydrochloric acid and pepsin
(commercially available)
Fibers, suspended substances Pressurized water, possibly surface-active agents
Light biological buildup Pressurized water
1) Do not use with the Tophit ISFET sensor! Instead, use commercially available acid cleaners for the food
industry (e.g. P3-horolith CIP, P3-horolith FL, P3-oxonia active).
NOTICE
Health hazard due to solvents
Do not use any halogen-containing, organic solvents or acetone. These solvents may
‣
destroy plastic components of the sensor and are also suspected carcinogens (e.g.
chloroform).
