1 Technical Information Cleanfit P CP473 Retractable staless steel process assembly with ball valve for ph and ORP electrodes pplication Chemical dustry Paper dustry Wastewater / dustrial water Power plants Refuse cerators Sugar dustry This assembly is very well suited to applications with fibrous contents or media which have a tendency to stick and could thereby terfere with the sealg system. Your benefits Safety: Safe and reliable process termation possible under nearly all conditions Comfortable operation: ssembly service ongog process: total disassembly of assembly body possible with closed ball valve (e.g. for exchangg sealg rgs, electrode holder etc.) Various immersion depths (tank/pipe stallation) Sealg water to screen off rse chamber utomation even for difficult processes: Fully-automatic calibration and cleang conjunction with Topcal S CPC310 Easy stallation: Version with pneumatic ball valve drive is supplied fully hosed-up Replaceable packg sleeve for easy seal replacement TI344C/07/en/

2 Function and system design Prciple Sealg system The "Measure" and "Service" operatg statuses can be changed the followg ways: Manually Pneumatically Pneumatically via Topcal S CPC310 or Topclean S CPC30 with optional CPR40 rsg block ll versions possible with limit position switch. Prciple sequence when movg the retractable assembly from "Service" to "Measure" Open ball valve Move assembly from "Measure" to "Service" Move assembly Close ball valve In the "Service" status (sensor moved back to the assembly), the ball valve seals the assembly off from the process. This means that cleang and calibration can take place and electrodes can be changed with terruptg the process. Warng! The rse chamber and the rse connections of the assemblies are open contact with the medium the measurg position, or at least when movg, and are thus exposed to the process pressure. For this reason, the let and let of the rse chamber must be protected by valves. These valves are available from Endress+Hauser as accessories (see product structure, "dditional equipment"). These valves close automatically the pneumatic version. The patented packg sleeve (made of PEEK) seals between the pneumatic drive system and the rse chamber. The packg sleeve contas three radial seals. dditionaly the packg sleeve improves the guidance of the sensor. For both sides of the ball valve are scrapers optionally available (pos ). Caution! When the assembly is the service position and the ball valve is open, the process pressure acts on the rse connections. Therefore the rse connections must be equipped with let and let safety seal Sealg system 1 Packg sleeve (made of PEEK) with 3 seals Rse let 3 Scraper PVDF/PTFE 4 Scraper PEEK with O-rgs 5 Rse let with manual or pneumatic let safety seal a Endress+Hauser

3 Sealg water function Limit position switches For the sealg-water function the assembly must be equipped with a pneumatic let safety seal for rse chamber let (see chapter "ccessories"). For sealg water the scraper no. 3 (above the ball valve) can be removed if needed. The pneumatic limit position switches serve as control elements and determe the sequence of the dividual steps. The followg types of limit position switches are available dependg on the order version (product structure, "ssembly operation, ball valve"): "Pneumatic limit position switch" version: 4 pneumatic switches (type, see "Mechanical construction") "Electric limit position switch" version: 3 pneumatic and ductive switches (types, see "Mechanical construction") Function S M3 S M3 S1 E S1 M4 M4 D S4 D S4 S3 S3 M C M1 Pneumatic limit position switches a M C Electrical limit position switches M1 S5 a C M1 M M3 M4 ssembly cylder Pneumatic connection block all valve drive Measurg: Pneumatics "Open ball valve" Limit position switch "all valve open" Pneumatics "ssembly Measurg" Limit position switch "ssembly Measurg" D E S1 S S3 S4 S5 Rsg put / put Rse let with non-return valve Service: Pneumatics "ssembly Service" Limit position switch "ssembly Service" Pneumatics "Close ball valve" Limit position switch (pneu.)

Compressed air is provided at position M1 (pneumatic "Open ball valve"). t the same time, compressed air is applied to M (limit position switch "all valve open"). The ball valve (C) opens. The rse chamber let valve (D) must be closed.. When the ball valve is completely open, the limit position switch M forwards compressed air to the pneumatics of the pressure cylder, put "ssembly measurg" (M3) and simultaneously to the limit position switch "ssembly measurg" (M4). The electrode holder moves of the assembly to the medium. 3. Once the limit position is reached, the limit position switch M4 sends a signal (5, "ssembly measurg" feedback signal) to the transmitter / DCS or to Topcal S / Topclean S. 4 Endress+Hauser

Compressed air is simultaneously provided at the pneumatics of the pressure cylder, put "ssembly service" (S1) and at the limit position switch "ssembly service" (S). The electrode holder moves from the medium to the assembly.. When the limit position is reached, the limit position switch S forwards pressure to position S3 (close ball valve) and position S4 (limit position switch "all valve closed") simultaneously. The ball valve (C) closes. 3. Once the ball valve is completely closed, a signal (6, "ssembly service" feedback signal) is sent from the limit position switch S4 (or the limit position switch S5 case of the version with electric limit position switches) to the transmitter / DCS or to Topcal S / Topclean S. t the same time, pressure is applied to the rse chamber let valve (D). Valve D opens as long as the pressure is applied. ny drop pressure causes this valve to close. Endress+Hauser 5
