Page 6 f 36 3 General descriptin 3.1 Pwer supply ptins Depending n the circuit type, the HF5 requires the fllwing pwer supply: a) HF52 (2-wire lp pwered, analg utputs): 10 28 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, HF54 and HF56 (3-wire, analg utputs ptinally cmbined with a digital utput): - HF53: 15 t 40 VDC r 12 t 28 VAC - HF54: 9 t 36 VDC r 7 t 24 VAC, galvanic islatin f the analg utputs and pwer supply - HF56: 85 240 VAC, galvanic islatin f the analg utputs and pwer supply HF53 and HF54: with bth utput circuits clsed, the typical current cnsumptin is 100 ma. HF56: typical current cnsumptin <50 ma at 85 VAC and <35 ma at 240 VAC Please verify the prduct identificatin label t determine which pwer supply ptin is installed n yur transmitter. c) HF556, HF557 and HF566 (digital utput nly): - HF556: 5 t 40 VDC r 12 t 28 VAC - HF557: PE (pwer ver Ethernet).The HF557 is nt available with a RS-485 interface and can be pwered nly via a LAN. - HF566: 85 240 VAC Typical current cnsumptin HF556 with USB interface : 100 ma HF556 with Ethernet (TCP/IP) interface and HF557 : 300 ma HF566 USB interface : <50 ma at 85 VAC and <35 ma at 240 VAC HF566 with Ethernet (TCP/IP) interface : <50 ma at 85 VAC and <35 ma at 240 VAC 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. 3.3 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)

Page 7 f 36 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-HW4v3-F2-005 3.4 Analg utput signals Parameter: 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. Output Scale: The scale f each analg utput can be set within the numerical limits f -999.99 and 9999.99. The D/A cnverters used t generate the analg utput signals feature a 16-bit reslutin. Signal Type: Bth analg utputs prvide the same type f signal. With the exceptin f the HF52 (always 4 20 ma), the type f signal can be selected with the ROTRONIC HW4 sftware t any f the fllwing: 0 20 ma, 4 20 ma, 0 1V, 0 5V r 0 10V (see 4.3). 3.5 Digital utputs Mdels with a digital utput can simultaneusly transmit 3 parameters: relative humidity, temperature and calculated parameter a) RS-485 serial interface Sme mdels f the HF5 are equipped with a RS-485 serial interface. This 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 PC by means f a USB prt r Ethernet (TCP/IP) prt. 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 Sme mdels f the HF5 are available with a USB r Ethernet interface in additin t the RS-485 interface. In this case the prtectin grade f the HF5 enclsure is n lnger IP65 / NEMA 4 rated.

Page 8 f 36 3.6 Service cnnectr The service cnnectr is a UART digital interface (Universal Asynchrnus Receiver Transmitter) with a mini- USB type cnnectr. This allws cnnecting the HF5 with a service cable t a PC running the ROTRONIC HW4 sftware. 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. Nte: any digital utput (USB, Ethernet and RS-485) ffers the same functinality as the service cnnectr. 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. 3.8 HW4 sftware versin cmpatibility The HF5 versin 2 requires HW4 versin 3.0.0 r higher fr full functinality f the Device Manager functin. 4 User cnfigurable settings and functins The HF5 ships cnfigured as specified n the custmer rder. Mdels with analg utputs nly 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 utput 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. We have prvided belw a shrt descriptin f the HF5 and prbe functins and als indicated the factry default settings. 4.1 Functin verview MEASUREMENT ACCURACY AND RELIABILITY (PROBE FUNCTIONS) AirChip 3000 Functins Humidity / temperature adjustment Autmatic humidity sensr test and ptinal drift cmpensatin 1-pint r multi-pint humidity calibratin r adjustment 1-pint r 2-pint temperature calibratin r adjustment Generate a time stamp fr calibratins and adjustments Retain and view last adjustment date and adjustment values Generate calibratin and adjustment prtcls Tests the humidity sensr fr drift caused by cntaminants and can be used t autmatically apply a crrectin.

Each system cmpnent has its wn micrprcessr, firmware and functins. Sme f these functins are unique t each system cmpnent. Other functins are fund in bth cmpnents. HF52 (2-wire, lp pwered transmitter): due t the necessity f limiting the current cnsumptin f the cmbinatin f HF52 and HC2 prbe t less than 4 ma, several prbe functins such as RH sensr test, data recrding and prbe adjustment are nt available with the HF52. The functins and settings f the HF5 transmitter and HygrClip 2 prbe (HC2) perate tgether as indicated belw: Functin / Setting HF5 HC2 Ntes Device prtectin X X Individual t the HF5 and HC2 prbe RS-485 address X X Individual t the HF5 and HC2 prbe Device Name X X Calculatin X X Data refresh rate Simulatr functin X X system X X X User defined descriptin The device name f the HC2 prbe is nt displayed by HW4 and is replaced with the HF5 Input Name Psychrmetric calculatin HF5 setting verrides HC2 prbe setting This setting has n effect n the HF5 and prbe. Depending n the mdel, the data refresh rate is as fllws: HF52: typically 5 s Other mdels: typically 1 s Generates fixed humidity and / r temperature value When enabled, the HF5 settings verride the HC2 prbe settings The HF5 setting verrides HC2 prbe setting regarding the HF5 signals. The HC2 prbe settings still apply when the prbe is used alne Make sure t use the same humidity symbl and the same temperature unit fr bth the HF5 and prbe.

Out-f-limits value alarm X X Analg utputs X X The HC2 prbe settings have an effect nly when the HF5 is enabled t mnitr alarms generated by the prbe When ut-f-limit values have been defined fr the same parameter fr bth the HF5 and prbe, any alarm is triggered based n the narrwest set f limits (assuming that the HF5 has been set t mnitr prbe alarms). Parameter and scale The HC2 prbe settings have n effect n the HF5 4.3 Analg utput signal type (except HF52) Bth analg utputs f the HF5 prvide the same type f signal. With the exceptin f the HF52 (always 4 20 ma), the type f signal can be selected with the ROTRONIC HW4 sftware t any f the fllwing: 0 20 ma, 4 20 ma, 0 1V, 0 5V r 0 10V. T select the analg signal type prceed as fllws: Use the apprpriate mdel f service cable (see Maintenance > Service Cable) t cnnect the service cnnectr f the HF5 t a USB prt f a PC with the HW4 sftware installed (HW4 3.0.0 r higher). Nte that the ROTRONIC USB driver must be installed n the PC as explained in the HW4 manual E-M-HW4v3-Main Start HW4 n the PC and search fr the HF5 (HW4 Main Menu Bar > Devices and Grups > Search fr USB Masters). After finding the HF5 with HW4, expand the device tree t see the HF5 functins. Select Device Manager. Fr further instructins see HW4 manual E-M-HW4v3-F2-005 N adjustment is required after changing the type f utput signal. 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.

Page 12 f 36 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 r 3 mm hex key. Prir t re-assembling the enclsure, verify that the red seal is sitting prperly in its grve n the base. 5.3 Installatin f the HF5 type D (thrugh wall munt) Munting psitin f the enclsure Vertical: HF52 type D withut keypad and display HF53 and HF54 type D withut keypad and display, and withut digital ptin Hrizntal: HF52 type D with keypad and display HF53, HF54 type D with keypad and display r with digital ptin All ther type D mdels Munting hardware The QMA-15 cnsists f a flange and cmpressin fitting and is designed t hld the prbe f the HF5 type D when munted thrugh a wall (see Accessries). The HF5 des nt require any additinal supprt. 5.4 Installatin f the HF5 type W (surface munt) Munting psitin f the enclsure Hrizntal: HF52, HF53, HF54, HF55 and HF56 type W

Page 13 f 36 Munting hardware Methd 1: The HF5 is supplied with 2 screws, 2 drywall anchrs and tw rubber washers. 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 50170 fr the transmissin f signals by cpper wires. When planning an installatin, the rules prvided by EN 50170 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 61000-6-1: 2001, EN 61000-6-2: 2005 - EN 61000-6-3: 2005, EN 61000-6-4: 2001 + 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:
