3.2 Installation conditions

3.2.1 Notes on installationThe assembly is designed for installation on tanks and pipes. Suitable nozzles must be available for this.

� Note! • When using standard glass electrodes, only installation positions are permitted in

which the middle axis of the assembly lies at least at an angle of 15° from the horizontal (see diagram). Otherwise, there will not be a reliable contact between the inner side of the pH membrane and the inner terminal leads via the electrolytes.

• When using an ISFET TopHit H sensor, there are, in principle, no restrictions for the installation position. An installation angle of 0 to 180° is, however, recommended.

� Caution! • For all assemblies with stainless steel pressure cylinders, we recommend to use a

flanged version when installing with inclined orientation. Otherwise, the weight of the assembly could affect the safety of the process connection.

• Avoid a siphon effect1 at the rinse chamber outlet when installing with inclined orientation. The inlet to the rinse chamber must be from below.

� Note! • The minimum diameter for direct installation in pipework is DN 50. This diameter is

required so that the assembly has sufficient distance from the pipe wall when brought into the "Measuring" position.

• Use a flow assembly to install the assembly in smaller pipe diameters (see Accessories).

• When designing the installation nozzle, please observe the total immersion depth in operation (sensor holder not inserted). Ensure that the sensor is always immersed in the medium during operation (see "Dimensions").

3.3.2 Installing the assembly into the process

� Note! Depending on the process connection, please observe the following: • Check the flange seal between the flanges before installing the assembly. • The thread adapter nut of thread G 1¼ does not function as a seal. Therefore, simply

tighten the thread adapter nut by hand.

Move the assembly into the "Service" position (electrode holder inserted in the assembly) and secure the assembly to the tank or the piping using your selected process connection.

3.3.3 Compressed air connection1

The assembly is operated with an air pressure of 4 to 8 bar (58 to 116 psi). The air must be filtered (40 µm) and be free of water and oil. There is no continuous air consumption. The air lines must have a minimum nominal diameter of 4 mm (0.16 inch).

� Caution! There must be a pressure-reducing valve upstream if the air pressure can increase to above 8 bar (116 psi) (including any short pressure surges).We recommend you also use a pneumatic throttle for lower pressures. This results in a smoother assembly operation. E+H offers such a throttle as an accessory (see chapter "Accessories").

The pneumatic limit position switches serve as control elements and determine the sequence of the individual steps.

1. Connect the compressed air supply line for "Assembly measuring" (TopCal/TopClean: hose no. ➁) to the upper G¼ pneumatics connection (Fig. 11).

2. Also, connect the compressed air supply line no. ➁ to the inlet (1) of the lower limit position switch (M2, via T-piece). This limit position switch supplies the position feedback signal "Assembly measuring".

3. When the "Measuring" position is reached, the air applied to the inlet (1) is switched through and can be tapped at the outlet (2) (TopCal/ TopClean: connect hose ➄ to the limit position switch outlet).

4. Connect the compressed air supply line for "Assembly service" (TopCal/TopClean: hose no. ➂) to the lower G¼ pneumatics connection.

5. Also, connect the compressed air supply line no. ➂ to the inlet (1) of the upper limit position switch (S2, via T-piece). This limit position switch supplies the position feedback signal "Assembly service".

6. When the position "Service" is reached, the air applied to the inlet (1) is switched through and can be tapped at the outlet (2) (TopCal/ TopClean: hose no. ➅).

Electric limit position switch connection

Like the pneumatic limit position switches, the electric limit position switches also serve as control elements and determine the sequence of the individual steps.

• Connect the NAMUR limit position switches to the corresponding terminals at the transmitter. Please, refer to the Operating Instructions of the transmitter for the terminal numbers. The following figure shows the electric limit position switch connection to the terminals 11 to 14 of the TopCal S control unit, as an example.

3.3.4 Rinse water connectionConnect the rinse water pipe to the designated rinse nozzle:• Assembly version with G1¼ internal thread process connection (see fig., pos. b):

Both rinse nozzles on the assembly are identical. Use one as an inlet and the other as an outlet.

• all other assembly versions (pos. a):Connect the rinse nozzles such that the inlet is bottom-up and the outlet top-down.

4 Operation

4.1 First commissioningBefore the first commissioning, make sure of the following items:• all seals are correctly seated (on the assembly and process connection)• the sensor is correctly installed and connected• the water supply line is correctly connected to the rinse connections (if fitted)• the limit position switches (according to assembly version) are correctly connected

� Warning! Danger of squirting medium.Before applying compressed air to the pneumatic assembly, make sure the connections are correctly fitted with either rinsing hoses or dummy plugs. Otherwise the assembly may not be put into the process!

4.2 Operating elementsUse the stop lock bolt to lock or release the retractable pipe (Fig. 18, Fig. 19).When using manually operated assemblies, the retractable pipe can be locked in both the "Measuring" position and the "Service" position. When using pneumatically operated assemblies, this can only be done in the "Service" position.

Releasing the stop lock bolt:

1. Pull the bolt out.

2. Turn the bolt by 90° so that the plastic grooves rest on the metal edge.

Locking the stop lock bolt:

3. Turn the stop lock bolt through 90° so that the plastic grooves are located above the recesses.

4. When the retractable pipe is turned clockwise, the bolt engages.

4.3 Manual operationMoving the assembly from the "Service" position to the "Measuring" position

1. Release the stop lock bolt catch.

2. Push the retractable pipe so that the sensor holder is inserted fully into the process.

3. Lock the sensor holder with the stop lock bolt. This prevents the retractable pipe from returning inadvertently into the "Service" position.

� Warning! Risk of injury!Always lock the sensor holder. Otherwise, the retractable pipe may exit uncontrolled as a result of the process pressure and injure somebody.

Moving the assembly from the "Measuring" position to the "Service" position

1. Release the stop lock bolt catch.

2. Pull the retractable pipe out as far as possible ("Service" position).

3. Lock the sensor holder with the stop lock bolt.

4. Complete the necessary service tasks.

4.4 Pneumatic operationOperation of the pneumatic version depends on the control fitted. Refer to the control operating manual for instructions.

� Caution! • During maintenance work (e.g. installing and removing the sensor), always lock the

assembly in the "Service" position by the stop bolt.• During the automatic rinse process, do not lock the retractable pipe by the stop bolt.

Otherwise the assembly can no longer move automatically to the "Measuring" position.• If a maintenance switch is fitted on the transmitter, set it to "Maintenance" or "Service".

� Note! It is not possible to lock the assembly in the "Measuring" position. The pneumatic system maintains the back pressure to the process pressure.

Maintenance CleanFit H CPA 475

5 Maintenance

� Warning! Risk of injury!Before starting maintenance work on the assembly, make sure that the process line and the tank are depressurised, empty and rinsed.

Move the assembly to the "Service" position and lock the retractable pipe by the stop lock bolt.

5.1 Cleaning the assemblyTo ensure a reliable measurement, the assembly and the sensor must be cleaned at regular intervals. The frequency and intensity of the cleaning operation depend on the process medium.

5.1.1 Manually operated assemblyAll parts in contact with the medium, e.g. the sensor and the sensor holder, must be cleaned at regular intervals. Remove the sensor1.• Remove light dirt using suitable cleaning agents (see chapter "Cleaning agents").• Remove severe fouling with a soft brush and a suitable cleaning agent.• Remove persistant fouling by soaking in a liquid cleaner and if neccessary by

cleaning with a soft brush.

5.1.2 Pneumatically operated assemblyPneumatically-controlled cleaning can be carried out regularly via the rinse connection and the corresponding equipment, e.g. with the fully automatic cleaning and calibration system TopCal S CPC 300.

5.2 Cleaning the sensorYou have to clean the sensor:• before every calibration• regularly during operation• before being returned for repair

You can remove and clean the sensor manually or perform cleaning in automatic operation2 via the rinse connection.

� Note! • Clean redox electrodes only mechanically and with water, do not use any chemical

cleaning agents. These cleaning agents apply a potential to the electrode that takes several hours to decay. This potential causes measuring errors.

• Do not use any abrasive cleaning agents. This can lead to irreparable damage of the sensor.

• After cleaning the sensor, rinse the rinse chamber of the assembly with copious amounts of water (possibly distilled or de-ionised). Otherwise, remaining residues of cleaning agent can corrupt measurement.

• If required, re-calibrate after cleaning.

1) in reverse sequence of operations to the installation procedure2) with the corresponding assembly equipment only

CleanFit H CPA 475 Maintenance

Endress+Hauser 21

5.3 Cleaning agentsThe selection of the cleaning agent is dependent on the degree and type of contamination. The most common contaminations and the suitable cleaning agents are listed in the following table.

� Caution! Do not use organic solvents containing halogen or acetone. These solvents could destroy plastic components of the assembly or the sensor and it is also partly suspected that they cause cancer (e.g. Chloroform).

5.4 Notes on calibrationRegular sensor calibration is vital for reliable measurement. The calibration cycles depend on the range of applications and the desired accuracy.You have to define the calibration cycles separately for each application. At the start, perform calibration frequently (e.g. weekly) to determine the operating characteristics of the sensor.Follow the corresponding instructions for calibration in the Operating Instructions of the transmitter used.

� Note! • The calibration cycles depend on the process conditions and the medium.• When using a symmetrical connection, there must be an electrical connection

between the potential matching (PML) and the buffer solution.• Do not allow a glass electrode to stand dry or pH sensors (including ISFET) to stand

in distilled water.• Do not use compressed air to blow clear automatic calibration systems with ISFET

sensors.

Type of contamination Cleaning agent

Greases and oils Substances containing tensides (alkaline)1 or water-soluble organic solvents (e.g. Ethanol)

1) do not use for the TopHit ISFET sensor! Instead, use commercially available acidic cleaning agents for the food industry (e.g. P3-horolith CIP, P3-horolith FL, P3-oxonia active).
