There are designed to be used as a Class III Non-Automatic Weighing Instrument. The Hanging Scale are self-indicating, mains or battery-powered, and can operate as a single or multi range (HJP and HJW) weighing instrument. The indicator consists of an analogue to digital conversion circuitry, microprocessor control circuitry, power supply, function keypad, non-volatile memory for storage of calibration and setup data, and a weight display contained within a single enclosure. 2 FUNCTIONAL DESCRIPTION 2.1 Construction (Figure 1) 2.1.1 Mechanical − Aluminium Alloy construction − Six digit segments LED digital screen (FJ3) − Six digit segments LED or LCD digital screen available in various colours (HJP, HJW and GJW models) − Operator function keypad − Plastic enclosure − LED indicators (battery status: charging or charged) − Dual display (HJP and HJW) 2.1.2 Devices Initial zero setting (≤ 20% Max) Semi-automatic zero setting (≤ 4% Max) Zero tracking (≤ 4% Max) Semi-automatic subtractive tare weighing Determination of stability of equilibrium Preset tare Accumulation High-resolution mode (5 sec maximum) Unit switch (kg, t) Gross, Net, Motion, Accumulation, Preset tare, Weighing range indicators − Remote operation − Hold function − − − − − − − − − − 2/8 2.2 Load cells 2.2.1 Any load cells may be used provided the following conditions are met: − there is a respective OIML Certificate of Conformity (R60) or a EC Test Certificate (EN 45501) issued for the load cell by a Notified Body responsible for type examination under Directive 2009/23/EEC; − the certificate contains the load cell types and the necessary load cell data required for the manufacturer’s declaration of compatibility of modules (WELMEC 2, Issue 5, 2009, No. 11), and any particular installation requirements. A load cell marked NH is allowed only if humidity testing to EN 45501 has been conducted on this load cell; − the compatibility of load cell and indicator is established by the manufacturer by means of the compatibility of modules form, contained in the above WELMEC 2 document, at the time of EC verification or declaration of EC conformity of type; and − the load transmission must conform to one of the examples shown in the WELMEC 2.4 “Guide for load cells”. 2.3 Operation 2.3.1 Switch-on At switch-on, the instrument performs a self-test during which all the relevant segments of the display are lit. The instrument attempts to set zero provided that it is within a range not exceeding 20 % of its capacity. 2.3.2 Semi-automatic zero setting The zero button operates provided that the instrument is within a range not exceeding 4 % of its capacity. 2.3.3 Over- and under-range If the load is less than zero, then the weight indications show an error “E2”. The load may be shown up to a maximum of nine divisions above Max, above which the weight indications are inhibited and replaced by “E1”. 2.3.4 Tare Subtractive tare balancing can be performed. 3/8 3 TECHNICAL DATA 3.1 Indictor specification Power supply 6 V DC 7 or 10 AH Maximum number of scale intervals Maximum Tare Maximum Preset Tare Load cell excitation voltage Minimum load cell impedance Maximum load cell impedance Minimum input voltage per scale interval Measuring range minimum voltage Measuring range maximum voltage Fraction of maximum permissible error Operating temperature range Load cell connection 3 750 6 kg or 15 000 kg (depending on configuration) 6 kg to 15 000 kg (depending on configuration) 5 V DC 350 Ω 1 200 Ω 1 µV 3.2 -1 mV/V 3 mV/V Pind = 0.5 -10 °C / +40 °C 4 or 6 wire connection maximum length = 2 m/mm2 Power supply The Hanging Scales are mains or battery-powered. A mains adaptor supplies 6 V DC to the Hanging Scales, any CE-marked adaptor may be used. The battery may be a 6 V DC 7 or 10 AH rechargeable battery. If the battery or supply voltage is too low, the display will show a battery symbol. 4 PERIPHERAL DEVICES AND INTERFACES There are no interface ports, and therefore no peripheral devices can be connected. 4.3 Remote operation The instrument may be operated remotely from an internally wired remote control unit (HJW model) or via a non-wired remote control unit (GJW, FJ3, HJP model). 5 APPROVAL CONDITIONS The certificate is issued subject to the following conditions: 5.1 Legends and inscriptions 5.1.1 The instrument shall bear the following legends near the display of the weighing result: Max Min e= 4/8 5.1.2 The instrument shall bear the following legends CE mark Green M Accuracy class Serial number Manufacturer’s mark or name Certificate number 6 LOCATION OF SEALS AND VERIFICATION MARKS 6.1 The rating plate (Figure 5) is located at the back of the instrument. The CE mark shall be impossible to remove without damaging it. The rating plate shall be impossible to remove without it being destroyed. The markings and inscriptions shall fulfil the requirements of Paragraph 1 of Annex IV of the Directive 2009/23/EC. − − 7 a mark of the manufacturer and/or manufacturer’s representative, or an official mark of a verification officer. ALTERNATIVES There are no authorised alternatives. 8 ILLUSTRATIONS Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 FJ3 – Weighing Hanging Scale (300 kg ~ 15 000 kg) GJW – Weighing Hanging Scale (200 kg ~ 1 000 kg) HJW – Weighing Hanging Scale (6 kg ~ 60 kg) HJP – Pricing Hanging Scale (6 kg ~ 100 kg) Rating plate 9 CERTIFICATE HISTORY Issue №.
