R CNS 10 - English espresso coffee machine - servings count 1.10 PROCEDURE IN CASE OF POWER FAILURE If there is a power outage, the system will store all data concerning the count of servings delivered. Since the update of the count takes place at the start of the delivery of the serving, if it is aborted due to a power outage, it is still counted and recognized by the dosing device. In this case, delivery is not performed and the serving is not counted. 1.11 TECHNICAL DATA GENERAL DATA • Power supply voltage 200-230Vac or 100-115Vac • Operating temperature 10-55°C • Operating humidity 30-85 % RH without condensation • Transformer 2 VA - clim.categ. T70/E - 4 KVca • Input - keys Switch / Pure contact • Signals for serial transmission RS232 0-5V CONNECTIONS for “PANEL” model • Power supply FAST - ON • Analogue inputs Included for AMPMODU2 • Digital inputs AMPMODU2 • High voltage outputs Included for FAST-ON • Serial connection AMPMODU2 CONNECTIONS for “COUNTERTOP” model • Power supply Bi-polar plug • Digital inputs Cable with activation keys inside the case • Serial connection 5-way circular connection 1.12 INSTRUCTIONS FOR INSTALLATION AND LIMITATIONS OF USE WIRING Wiring of the cards must be laid out in consideration of the need to separate low voltage from high voltage connections. The length of any cable must be as short as possible to allow correct connection. If necessary, screened cables must be used. The unit must also be located far from devices which may create electromagnetic disturbances when in operation, such as pumps, solenoid valves, remote switches, motors in general, and neon lights. SURROUNDINGS The unit must be placed as far as possible from potential heat sources and excessive humidity and from places where, for any reason, condensation may form. SOILING Inside the machine, the card must be suitably protected against soiling. By definition, “in general, the inside of a unit having a case which sufficiently protects it from dust is considered to be protected against soiling” (EN 60335-1).
espresso coffee machine - servings count MESH FILTER In order to meet the standards of directives concerning electromagnetic compatibility, it may be necessary to provide the machine with a mesh filter outside the card. In this case, its installation requires compliance with a few basic rules: • the filter (if of a type with a metallic body) must be installed on the metal frame of the unit, with an electrical path of low impedance towards earth. • It must be installed as near as possible to the entry point of the of the power cable, with short input and output connections that are set well apart from each other, to avoid disturbances between the mains, loads and the unit. If the filter is not installed in compliance these instructions, it may lose all or part of its effectiveness. PERFORMANCE Best performance of the card is obtained at an ambient temperature of roughly 25°C. For higher or lower temperatures, precision and heat dissipation results tend to worsen. However, the temperature range as defined in the electrical characteristics is adhered to. To avoid permanent damage to some components, remain within the range 0...70°C. 1.13 WARNINGS DANGER The unit contains parts with a high voltage power supply. Before performing any work, disconnect the unit from the electrical mains. START-UP Before providing power to the unit, make all required connections. PROTECTION Ensure that all accessible metal parts which may receive live current due to an insulation defect are permanently and securely attached to the earth terminal of the machine. Ensure that the earth terminal of the machine is connected to an efficient earth protection EXTERNAL COMPONENTS The insertion of components outside the card which are required to ensure suitable reduction of disturbances must not compromise the safety of the unit. This means that they must be of a suitable type and value. COMPONENTS If necessary, we reserve the right to replace the components used with other devices produced by other manufacturers but with the same electrical and regulatory characteristics. SOFTWARE If necessary, we reserve the right to make partial corrections to the described procedures during the software development stage, to allow easier or more effective use of the machine or a more coherent development of software, without modifying the functional aspects of the machine. SAFETY Protection against electrical shock, fire hazard, mechanical risks or hazardous malfunctions in other parts of the machine does not depend on correct operation of the electronic circuit. Therefore, where necessary, the machine must be equipped with safety devices which are independent of the electronic circuit (e.g. pressure overload safety valve). English - CNS 11 R
