3 Page 3 f 31 Applicability: This manual applies t all instruments f the HygrFlex HF5 series with firmware versin 1.x, where 1.x can be 1.0, 1.1, etc. Changes t the last digit f the versin number reflect minr firmware changes that d nt affect the manner in which the instrument shuld be perated. 1 Overview The HygrFlex HF5 transmitter series is designed fr fixed installatin in applicatins where high measurement accuracy is required and can be used with any f the HygrClip 2 plug-in prbes. The mst basic HF5 mdels prvide analg utput signals crrespnding t any tw f the fllwing: relative humidity, temperature r calculated value such as dew pint, enthalpy, mixing rati, etc. Other mdels prvide either a digital interface and tw analg utput signals r a just a digital interface. The digital interface allws the simultaneus reading f relative humidity, temperature and calculated value. Depending n the prbe mdel, the HF5 can measure cnditins within the range f 0 t 100 %RH and -100 t 200C (-148 t 392F). The wide assrtment f HygrClip 2 humidity-temperature prbes can meet almst any applicatin requirement. The HygrClip 2 prbes feature well prven, durable sensrs. Digital signal prcessing within the prbe ensures cnsistent prduct perfrmance and als facilitates the task f field maintenance with features such as ptentimeter free digital calibratin, ht-swapping f the prbe, etc. Based n the ROTRONIC AirChip 3000 digital technlgy the HF5 series and HygrClip 2 prbes ffer the fllwing user functins: User cnfigurable settings Calculatin f psychrmetric parameters such as the dew r frst pint Humidity temperature calibratin and adjustment 1) Simulatr mde Autmatic humidity sensr test and drift cmpensatin 1) Sensr failure mde 1) Data recrding 1) 1) Except mdel HF52 (2-wire transmitter) The ability fr the user t easily update bth the HF5 and HygrClip 2 prbe firmware means that instruments f the HF5 series can be kept up-t-date regarding any future functinality imprvement. HF5 transmitters with analg utput signals and ptinal digital utput: tw types f electrnic circuit are available: HF52: 2-wire, lp pwered circuit (4 20 ma current signal) and HF53: 3-wire circuit with vltage r current signals.

5 Page 5 f Display and keypad ptin The LC display ptin fr the HF53 and HF55 has a backlight. The LC display ptin fr the HF52 des nt have a backlight. The upper line crrespnds t relative humidity r dew / frst pint and the bttm line crrespnds t temperature. The display can be cnfigured t shw a trend indicatr n each line: : increasing value : decreasing value In the event f an alarm the display shws the symbl [! ] t the right f the value. Fr instructins see the fllwing HW4 manual: E-M-HW4v2-F General descriptin 3.1 Pwer supply Depending n the circuit type, the HF5 requires the fllwing pwer supply: a) HF52 (2-wire, lp pwered): VDC - depending n the lad cnnected t the utput(s). The minimum supply vltage can be determined as fllws: V min = 10 V + (0.02 x Lad*) *Lad resistance in hms. Fr the maximum lad f 500, the minimum supply vltage is 10 + (0.02 x 500) = 20 VDC. With bth utput circuits clsed, the maximum current cnsumptin is 40 ma. b) HF53 (3-wire with analg utputs): 15 t 40 VDC r 12 t 28 VAC. With bth utput circuits clsed, the maximum current cnsumptin is 50 ma. c) HF55 (3-wire) with digital utputs: 5 t 40 VDC r 12 t 28 VAC. Maximum current cnsumptin: Mdel with USB interface: Mdel with Ethernet (TCP/IP) interface: 50 ma 300 ma 3.2 Measured parameters The HygrClip 2 prbe used with the HF5 transmitter measures relative humidity with a ROTRONIC Hygrmer IN1 capacitive sensr and temperature with a Pt100 RTD.

6 Page 6 f Calculated parameters Using the ROTRONIC HW4 sftware, the HF5 can be cnfigured by the user t calculate ne f the fllwing parameters: Dew pint (Dp) abve and belw freezing Frst pint (Fp) belw freezing and dew pint abve freezing Wet bulb temperature (Tw) Enthalpy (H) Vapr cncentratin (Dv) Specific humidity (Q) Mixing rati by weight (R) Vapr cncentratin at saturatin (Dvs) Vapr partial pressure (E) Vapr saturatin pressure (Ew) Nte: sme f the abve parameters depend n the value f the barmetric pressure. Using the ROTRONIC HW4 sftware, a fixed barmetric pressure value can be specified. Fr instructins see the fllwing HW4 manual: E-M-HW4v2-F Analg utput signals (HF52 and HF53) HF52 and HF53 With the ROTRONIC HW4 sftware any f the tw analg utput signals can be made t crrespnd t ne f the fllwing: Relative humidity Temperature Calculated parameter Any utput can als be disabled. The scale f each analg utput can be set within the numerical limits f and The D/A cnverters used t generate the analg utput signals feature a 16-bit reslutin. HF53 The type f utput signal can be changed by means f jumpers t ne f the fllwing: 0 20 ma, 4 20 ma, 0 1V, 0 5V r 0 10V (see 5.2). Bth utput signals are autmatically cnfigured with the same signal type. N adjustment is required after changing the type f utput signal. 3.5 Digital interface (HF53 with digital ptin and HF55) a) RS-485 serial interface All HF5 mdels with a digital interface have a RS-485 serial prt. When the number f available netwrk prts is limited, this prt can be used t cnnect tgether up t 64 devices in a multi-drpped arrangement. In principle, an unlimited number f such netwrks can be mnitred with the HW4 sftware, but each RS-485 multi-drp netwrk is limited t 64 devices. The HF5 can be used either as a slave r a master, withut special cnfiguratin. The master is autmatically the device that is directly cnnected t a netwrk (PC r LAN) by means f a USB prt r TCP/IP prt.

7 Page 7 f 31 RS-485 Cmpatibility: The cmmunicatin prtcl used by the HF5 and ther AirChip 3000 prducts is nt cmpatible with the prtcl used by the previus generatin f ROTRONIC instruments. D nt cnnect legacy prducts and AirChip 3000 prducts t the same RS-485 multi-drp netwrk. b) USB r Ethernet interface The HF5 is als available with the fllwing interface cmbinatins: USB + RS-485 r Ethernet +RS-485. In this case the prtectin grade f the HF5 enclsure is n lnger IP65 / NEMA 4 rated. 3.6 Service cnnectr The service cnnectr (UART interface with a mini-usb type cnnectr) allws cnnecting the HF5 either t a PC running the ROTRONIC HW4 sftware r t a prbe input f anther instrument that is cmpatible with the HygrClip 2 (HC2) prbes. In bth cases a service cable is required. See Maintenance fr the lcatin f the service cnnectr and fr the type f service cable t be used. The service cnnectr is used t cnfigure the HF5 and t and update its firmware with the HW4 sftware. When the HF5 des nt have its wn display, the service cnnectr can be used t display the data measured by the HF5 n anther instrument such as the HP23 hand-held indicatr. Cnnecting the HF5 service cnnectr t the prbe input f anther instrument des nt give access t prbe functins such as such as humidity and temperature adjustment, data recrding, etc. Nte: the digital interface (USB, Ethernet and RS-485) ffers the same functinality as the service cnnectr but des nt allw cnnecting the HF5 t a HP23 hand-held calibratr. 3.7 Prbe The HF5 is cmpatible with all available mdels f HygrClip 2 prbes. Fr detailed infrmatin n the prbes see dcument E-M-HC2 Prbes-V1. 4 User cnfigurable settings and functins The HF5 ships cnfigured as specified n the custmer rder. Mdels with analg utputs can be installed and used just as any cnventinal humidity and temperature transmitter and mst users will never need t use the HF5 cnfigurable settings and functins. Mdels with a digital interface generally require sme cnfiguratin by the user. Making use f the HF5 and prbe cnfigurable settings and functins is entirely up t the user and the apprpriate settings depend n the user applicatin.

13 Page 13 f 31 5 Mechanical installatin 5.1 General guidelines Relative humidity is extremely dependent n temperature. Prper measurement f relative humidity requires that the prbe and its sensrs be at exactly the temperature f the envirnment t be measured. Because f this, the lcatin where yu chse t install the prbe can have a significant effect n the perfrmance f the instrument. The fllwing guidelines shuld guarantee gd instrument perfrmance: a) Select a representative lcatin: install the prbe where humidity, temperature and pressure cnditins are representative f the envirnment t be measured. b) Prvide gd air mvement at the prbe: air velcity f at least 200 ft/ minute (1 meter/secnd) facilitates adaptatin f the prbe t changing temperature. c) Avid the fllwing: (1) Clse prximity f the prbe t a heating element, a cling cil, a cld r ht wall, direct expsure t sun rays, etc. (2) Clse prximity f the prbe t a steam injectr, humidifier, direct expsure t precipitatin, etc. (3) Unstable pressure cnditins resulting frm excessive air turbulence. d) Immerse as much f the prbe as pssible in the envirnment t be measured. e) Prevent the accumulatin f cndensatin water at the level f the sensr leads. Install the prbe s that the prbe tip is lking dwnward. If this is nt pssible, install the prbe hrizntally. 5.2 HF5 enclsure The HF5 enclsure cnsists f a base and a cver held tgether with 4 screws. T pen the enclsure, use a metric 2.5 mm hex key. Prir t re-assembling the enclsure, verify that the red seal is sitting prperly in its grve n the base.

The base f the enclsure has 2 screw-wells (see drawing) that are nrmally clsed at the bttm. Use the template prvided with the HF5 t drill munting hles in the wall and insert the drywall anchrs. Place a rubber washer n each screw. Insert a screw in each well and push t pen the bttm f the well. Methd 2: When a DIN-rail (35 mm / 1 3/8 ) is available use part AC5002 (nt included). This is a DIN-rail munting kit cnsisting f 2 clamps that attach t the back f the enclsure with the screws prvided. 6 Electrical installatin 6.1 General wiring guidelines Pwer supply wiring Heavy machinery and instrumentatin shuld nt share the same pwer supply wiring. If this cannt be avided, nise filters and surge prtectrs shuld be used. Mst UPS devices have thse features already integrated. General guidelines fr signal cables The fllwing guidelines are derived frm Eurpean Standard EN fr the transmissin f signals by cpper wires. When planning an installatin, the rules prvided by EN shuld be fllwed under cnsideratin f lcal circumstances t determine the psitin f machines and equipment. All ROTRONIC prducts are tested fr Electrmagnetic Cmpatibility accrding t EMC Directive 2004/106/EG and fllwing Eurpean standards: - EN : 2001, EN : EN : 2005, EN : A11 Whenever the level f electrmagnetic interference is expected t be high, bth the instruments and signal cables shuld be placed as far away as pssible frm the surce f interference. In general, signal cables shuld be installed in bundles r channels / cnduits, separate frm ther cables as indicated in the table belw:

Fr cabling undergrund in between buildings, we recmmend the use f special fiber ptic cables. If this is nt pssible, use cpper cables that are suitable fr undergrund installatin. 6.2 Guidelines fr RS-485 wiring (HF53 with digital ptin and HF55) See dcument E-DV04-RS485.01: RS485 Netwrk Installatin and Start-up Guidelines 6.3 Cable grip and cable specificatins The HF5 is supplied either with ne M16 sealing cable grip r with a ½ cnduit adapter. The M16 cable grip prvides effective sealing nly with cables having the prper utside diameter. Preferably, use a cable with an utside diameter f 6 t 7 mm (0.236 t inch) with 18 AWG wires.

17 Page 17 f Wiring HF52: 2-wire, lp pwered transmitter Electrical diagram The maximum permissible cable length cnnecting the HF52 t ther devices is determined by the ttal resistance resulting frm the additin f the cable resistance and that f the devices cnnected in series with the unit.
