Electrical fitting: The RT 110 contact system is designed according to EN12953-9 requirements included 250000 switching cycles with electrical parameters marked on the RT 110 contact system plastic cover. Using the appliance other than described AC-1, AC-3, AC-15 or DC-13 modes, may not be as a limiter. The RT contact system and any cooperated external contactors or relays shall, against the effects of short circuits, be over current protected with 0,6 safety factor. It means, that the nominal current of the device, as stated by the manufacturer, is to be multi­ plied by a safety factor of 0.6. Example: Rated load for AC15 is 1A. Safety factor is 0,6 in consequence, fuse = 1A x 0,6 = 0,6A or less. Endurance of any external contactors and relays must be according to EN12953-9, which means 250000 switching cycles under conditions similar to operating conditions and be capable of a mechani­ cal life time of 3000000 switching cycles. Conditions similar to operating conditions covers chemical and climatic influences as well as electrical and mechanical stresses. In addition, contactors must fulfil EN60947 and relays must fulfil EN60255. Wires for connecting the RT 110 must be according to the specifications of prEN 50156-1 standard and may not de­ crease electrical safety or IP-protection of the appliance. After connection to the wir­ ing use cable ties or similar to protect the wires of slippingout of the screw-terminals in order to prevent unintended movement of the wires. Generally, when there is no pressure working on the appliance: –– Terminal 1 is C (common one) –– Terminal 2 is NC (terminal 2 is normally connected to common terminal 1) –– Terminal 4 is NO (terminal 4 is normally opened with common terminal 1) NOTICE, there are two different ways of working for pressure limiter: one as a pressure limiter for rising and another one as a pressure limiter for falling. For identification, there is adequate description on the bottom of housing (see below examples). For rising: When the pressure rise up and achieve set­ ting point, contacts change: –– 1-2 disconnection –– 1-4 connection When the pressure fall down below setting point + diff erential value, contacts change back: –– 1-2 connection –– 1-4 disconnection For rising: When the pressure fall down and achieve setting point, contacts change: –– 1-2 connection –– 1-4 disconnection When the pressure rise up above setting point + diff erential value, contacts change back: –– 1-2 disconnection –– 1-4 connection Locking/reset mechanism: Since the pressure limiter type RT 110 has no lockout with manual resetting, this functions must be realized externally as a part of a safety logic e.g. by external contactors and/ or relays which then are to be used according to the requirements of prEN50156-1 standard for safety relevant hardware. External closure must not be interlocked, while loss of auxiliary energy must lead to a closure. Resetting must not be automated, it has to be performed manually. Resetting on fault must lead to a repeated closure. When RT limits, for rising or falling applica­ tion, the external safety logic must change to the fail safe position. Pressure fitting: In order to prevent malfunction of the limiter, the pressure installation must be according to Danfoss Instruction 017R9315 and below description harmonized with the requirements of EN12953-9. For safety purpose, accessory 060-333366 and 060-007166 can not be used with the limiter! Steam boilers: Connecting pipes for the limiter shall be connected to the steam space of the boiler and if necessary, the limiter shall be protected from the steam temperature by a water seal. If an insolating valve is fitted on the connection pipe, an insulation valve shall be installed which shall be capable of being locked. Fully fl ooded hot water generators: The limiter shall be connected to the supply pipe before the fi rst shut-off valve. The limiter body shall be installed verti­ cally so that dirt does not enter the limiter. If there is the possibility of sludge build-up in the connection pipe it shall be possible to purge the pipe. Such purging must not remove the water seal or introduce dirt into the water seal. In addition, the connection pipe and its boiler connection must be designed for cleaning and inspec­ tion and have a clear bore of at least: 1. where pipe supplies only the imiter: ø8mm- if pipe is less than 1m long. ø15mm - if pipe is greater than 1m long. 2. where pipe supplies the limiter in addition to other limiters: ø20mm - for all lengths of pipes. Provision shall be made for functional test­ ing of the limiter. The result of the test shall be clearly indicated to the boiler operator. Setting: RT 110 with factory setting: RT 110 with factory setting are secured by manufacturers sealing. Setting screw and plastic cover with window can not be turn- ed or removed without breaking the seal. Connection of wires to the RT 110 contact system must be performed after removing the sealing and plastic cover, without any changing of the setting value. In order to protect RT device against changing chang­ ing of the setting, after wiring, a seal must be applied by the customer. RT 110 without factory setting: The same conditions as in the RT 110 with factory setting paragraph. Checking accuracy of the setting by the customer must be done with calibrated pressure gauge. Scale can be used only as an indica­ tion of the pressure setting. Adjusting the appliance to more than 3 bar or less than 0.05 bar will cause faulty operation to the appliance and safe function is not reliable any more!

017R9327 017R9327 IC.PI.P10.C1.ML/520B1837 Dansk Instruktion / Instruction Fail Safe Pressure limitter type RT 110 Data Driftssikker pressostat type RT110 i rustfrit stål til afl astning af kedlen - iht. EN12953-9. Eltilslutning: RT110-kontaktsystemet er konstrueret i henhold til til kravene i EN12953-9, herunder 250.000 omkoblingscykluser, og de elek- triske parametre er markeret på apparatets plastdæksel. Anvendes apparatet på andre end de beskrevne AC-1, AC-3, AC-15 eller DC-13-kategorier, vil det muligvis ikke være som pressostat. RT-kontaktsystemet og evt. tilhørendeek- sterne kontaktorer eller relæer skal være overstrøms- beskyttede med en sikkerhedsfaktor på 0,6 mod virkningen af kortslutninger. Det bety- der, at den mærkestrøm, producenten angi- ver for apparatet, skal multipliceres med en sikkerhedsfaktor på 0,6. Eksempel: Den nominelle belastning for AC15 er 1 A. Sikkerhedsfaktoren er 0,6 Sikringen skal derfor være = 1 A x 0,6 = 0,6 A eller mindre. Holdbarheden for evt. eksterne kontaktorer og relæer skal opfylde kravene i EN12953-9, hvilket vil sige 250.000 omkoblingscykluser under forhold svarende til driftsforholdene, og den mekaniske levetid skal være 3.000.000 omkoblings-cykluser. Forhold svarende til driftsforholdene dækker kemiske og kli- mamæssige samt elektriske og mekaniske påvirkninger. Derudover skal kontaktorer opfylde kravene i EN60947og relæer kravene i EN60255. Ledninger til tilslutning af RT110 skal være udformet i henhold til specifi kationerne i EN50156-1 og må ikke forringe apparatets elsikkerhed eller IP-beskyttelse. Efter at ledningerne er tilsluttet, skal der monteres ledningsbindere eller lignende for at forhin- dre ledningerne i at komme fri af skrueter- minalerne, og derved forebygge, at lednin- gerne fl ytter sig utilsigtet. Låse-/reset-mekanisme: Eftersom pressostater type RT110 ikke har nogen indkoblingsspærring med man. re- set, skal disse funktioner klares eksternt som en del af det logiske sikkeredssystem, fx gennem eksterne kontaktorer og/eller relæer, som så skal anvendes på sikker- hedsrelevant udstyr i henhold til kravene i EN50156-1. Ekstern afspærring må ikke kunne blokeres og tab af hjælpeenergi skal føre til afspær- ring. Reset må ikke i en fejlsituation skal igen føre til afspærring. Tryktilslutning: For at hindre funktionssvigt i pressostaten skal trykinstallationen udføres i henhold til Danfoss’ instruktion 017R9315 og til neden- stående beskrivelse, der er i overensstem- melse med kravene i EN12953-9. Dampkedler: Tilslutningsrørene til pressostaten skal forbindes med kedlens damprum, og pressostaten skal om nødvendigt be- skyttes mod dampens temperaturind- virkning ved hjælp af en vandtæt pak- ning. Hvis til slutningsrøret er udstyret med en rørbrudsventil, skal der monteres en lås- bar afspærringsventil. Af sikkerhedsmæssige grunde må reservede- lene 060-3333 og 060-0071 ikke ikke anven- des med pressostaten! Varmvandsgeneratorer: Pressostaten skal tilsluttes til tilgangsrøret før den første lukkeventil. Pressostathuset skal monteres lodret, så der ikke kan trænge snavs ind i pressostaten. Hvis der kan samle sig slam i tilslutningsrøret, skal det være muligt at rense røret. En sådan rensning må ikke bevirke, at den vandtætte pakning fj ernes eller påføres snavs. Derud- over skal tilslutningsrør og kedeltilslutning konstrueres, så de kan rengøres og in- spiceres og de skal have en fri huldiameter på mindst: 1. for rør, der kun forsyner pressostaten: Ø 8 mm - hvis røret er mindre end 1 m langt. Ø 15 mm - hvis røret er mere end 1 m langt. 2. for rør, der forsyner pressostaten samt andre pressostater: Ø 20 mm- for alle rørlæng- der. Der sørges for, at pressostaten bliver funk- tionstestet. Kedeloperatøren skal have fri adgang til resultatet af denne test. Indstilling: RT110 med fabriksindstiling: RT110’s fabriksindstilling er sikret med pro- centens forsegling. Låsegreb og plastdæk- sel med rude kan ikke drejes eller fj ernes, uden at forseglingen brydes. Ledningerne til RT110-kontaktsystemet skal for-bindes, efter at forseglingen og plastlåget er fj ernet, men uden at indstill- ingsværdien ændres. For at beskytte RT-en- heden mod ændring af ind-stillingen skal kunden forsegle låsegrebet, når lednin- gerne er forbundet. RT110 uden fabriksindstilling: Samme forhold gør sig gældende som i af- English Data Fail Safe Pressure limiter type RT110 Stainless Steel as a limiting device of the boiler - according to EN12953-9.

After connection to the wiring use cable ties or similar to protect the wires of slipping- out of the screw-terminals in order to prevent unintended movement of the wires. Locking/reset mechanism: Since the pressure limiter type RT110 has snittet for RT110 med fabriksindstilling. Når kunden kontrollerer indstillingens præci- sion, skal det ske med et kalibreret mano- meter. Skalaen kan kun anvendes som en indikation af trykindstillingen. Hvis apparatet indstilles til mere end 3 bar eller mindre end 0,05 bar, vil det ikke kunne arbejde, og sikkerhedsfunktionen vil ikke længere være driftssikker!

To ensure IP66 (units with automatic reset) or IP54 (units with external reset) grade of RT enclosure it is necessary to assemble this gland as shown in the fig. 2. If this gland is not used with a cable, a metal blinding should be also assembled. Damp out strong pressure pulsations. A damping coil, fig. 3 or fig. 4, will often be sufficient. Insert a water-filled tube loop as a temperature lock (e.g. a 10 mm Cu tube) if at high plant temperatures there is a risk that the pressure connection of the control will become heated to more than 100 °C. Position the pressure control so that on water plant it cannot be exposed to frost. It can operate on an air cushion, for example. Setting The pressure controller is set by rotating the knob (5), at the same time reading the main scale (9). See fig. 1. The differential is set by rotating the differential adjusting nut (19) to the value indicated by the use of the nomogram in fig. 6. The maximum operating pressure is thus the sum of the setting pressure and the differential. Example It is desired to control the pressure in an oilfired steam boiler by the use of an RT 116. Maximum pressure 9 bar. Minimum pressure 8.2 bar. Differential 9 - 8.2 = 0.8 bar. 1. Connect the oil burner to terminals 1-2 of the pressure switch. 2. Set the pressure switch for 8.2 bar by rotating the knob (5). 3. Set the differential adjusting nut (19) at the figure 7 which is found by reading the nomogram in fig. 6.

For at sikre kapslingsgrad IP66 (enheder med automatisk reset) eller IP54 (enheder med ekstern DANSK RESET) er det nødvendigt at montere denne kabelforskruning som vist i fig. 3. Hvis denne kabelforskruning ikke bruges sammen med et kabel, bør der monteres en blindprop (metal skive). Dæmp kraftige trykpulsationer. Ofte er dæmpesløjfe fig.3 eller fig. 4 tilstrækkelig. Indskyd en vandfyldt rørsløjfe som temperaturspærre, fx af10 mm Cu-rør, hvis der i anlæg med høje temperaturer er risiko for at pressostatens tryktiIslutning kan opvarmes til over 100 °C. Anbring pressostaten, så den ved vandanlæg ikke udsættes for frost (lad den fx ar-bejde på en luftpude).
