1. Safety and protection measures 1.1 General safety instructions 1.3 Hazard areas and residual hazards The RF20H (Extract 810 and 820) retractable holder is designed in a way that when the operation manual is observed the product does not cause any hazards. Retractable holders are connected to tanks and piping that may be under pressure. Leaking of process liquid only occurs in case of negligence and improper operation. • Read the operation manual before use.
1.5 Safety equipment Position The retract protection prevents the “service” insertion rod from retracting without sensor in the process as this would cause a leakage of process liquid. • The sensor can only be installed/ removed when the holder is in the “service” position. • Disabling the retract protection is considered as negligence. Position In the “measuring” position the “measuring” sensor is immersed in the drive unit. • You cannot remove the sensor.

2.2 Process integration Process Control System RF20M (Exmatic 450) Transmitter 24V DC Air 4-6 bar Cleaning solution Drain Fig. 2: Process flow Control The RF20H (Extract 810 and 820) retractable holder can be operated by the automatic control EXmatic. It optimally matches the functions of the holder. Transmitter The retractable holder inserts a sensor in the process liquid transmitting its measuring results to a transmitter.
CAUTION! 8 3. Delivery 3.1 Package contents The retractable holder is inspected at the factory and delivered ready for installation in a packaging providing optimal protection for the holder. Package contents: • RF20H (Extract 810 and 820) holder • hexagon key 2.5mm • 4 spare screws M 4 x 8 (DIN 912) • 2 spacer for sensors • operation manual For the RF20H (Extract 810) S.S./Hastelloy holder you will additionally receive a material certificate Store the holder in the packaging.
CAUTION! justing the protection 4.4cage 4. Installation Adjusting the protection cage 9 DANGER! 4.1 Preparing the system Ensure that • Sufficient working space for operation of the retractable holder is available. • The process is shut off. • Tank and tubing are pressure-free, empty and clean. • Connection flange and process connection of the retractable holder fit together. • The process seal is positioned on the connection flange.
DANGER! 10 4.5 Installing the cleaning pipes Cleaning of the sensor is possible while the process is running. This requires supply and draining of cleaning liquid to the cleaning chamber. If cleaning of the sensor is not desired the cleaning ports must be sealed by pegs. A B How to install the cleaning pipes: 1) Install valve and dirt trap in the cleaning pipe for the cleaning liquid supply. WARNING! 2) Attach supply cleaning pipe to the cleaning port “IN”. .
How to install the pneumatic tubes: 1 I nsert pneumatic tube ø = 6mm in connection 1 (blue) for the air supply “service” position. 2 Insert pneumatic tube ø= 6mm in connection 2 (black) for air supply, “meassuring position”. 3 Insert pneumatic tube ø = 4mm in connection 3 (blue) for the reply signal “service” position. 4 Insert pneumatic tube ø = 4mm in connection 4 (black) for the reply signal “measuring position”. 4.7 Installing the sensor Ensure that • the holder is in the “service” position.
CAUTION! CAUTION! 12 5. Operation DANGER! DANGER! CAUTION! 5.1 Commissioning the holder 5.2 Automatic operation of the holder CAUTION! Risk of injury by leaking process liquid! Burns or tissue destruction depending on process liquid property. DANGER! • Wear goggles and protective clothing! • Check all seals and connections of holder before starting the process.
manual! " DANGER! Constructional modifications must be agreed with the 6. Servicing manufacturer! 6.3 Removing the sensor 6.1 Servicing instructions " 13 How to remove the sensor: Tubing and tanks must be pressure-free,1) empty and clean position. Move holder to “service” • Establish a service plan adapted to your process! 2) Remove sensor cable. CAUTION! WARNING! before the holder from the3) process • Leave servicing disconnecting works to qualified staff. Remove PG cable gland.
CAUTION! 14 CAUTION! 6.5 R emoving the cleaning chamber with process connection DANGER! System is under pressure. Process liquid will leak when holder is disconnected from process in an inappropriate way. DANGER! • Tubing or tanks must be pressure-free, empty, clean and without potentially WARNING! explosive atmosphere. CAUTION! CAUTION! Interrupt the process. Ensure that the system is pressure-free, DANGER! empty, clean and without potentially WARNING! explosive atmosphere.

DANGER! DANGER! 16 6.8 Installing the insertion rod The descriptions refer to Fig. 17 and Fig. 18 in chap. 6.7 Removing the insertion rod! WARNING! How to assemble the insertion rod and the drive unit: 1) Adjust slots in insertion rod “C” to piston “B” and put together. 2) Insert pins “F” 3) Tighten screws “E”. 4) Grease inside wall of cylinder “D”. 5) Slide cylinder “D” over insertion rod “C”. 6) Adjust cylinder “D” to cylinder extension “A”. 7) Press until cylinder snaps into place.
7. Trouble shooting Refer to the instructions and warnings in the specified chapters. 7.1 Holder does not move from the "service" position to the "measuring" position possible reason no compressed air pressure too low no sensor loose sensor measure check pneumatic tubes (chap. 6.4, 4.6) pressure must be between 4 and 6 bar (chap. 4.6) Installing the sensor (chap. 4.7) tighten sensor (chap. 4.7) 7.
7.6 Sensor breaks frequently possible reason sensor too long seals on sensor are missing Process liquid contains solids measure choose adequate sensor (chap. 4.7) insert seals on sensor (chap. 4.7) Adjusting the protection cage(chap. 4.4) 7.7 Leakage of process liquid at inspection window possible reason wetted sealings are defect measure Replacing the wetted sealings (chap. 6.6) 7.
