G2 USES NOT PERMITTED The transfer of fluids with different characteristics than those indicated above is not allowed. In particular: • Gasoline, solvents and inflammable liquids with PM < 55°C (danger of fire/explosion). • Liquid food products (contamination of the same). • Water (pump oxidation). • Corrosive chemical products (pump corrosion). • Liquids with viscosity > 20 cSt (motor overload). G3 ABSORBED POWER The CUBE MC stations must be powered by a power line with the same RATED VOLTAGE / FREQUENCY as that indicated on the IDENTIFICATION PLATE. The maximum acceptable variations from the electrical parameters are: - VOLTAGE +/- 5% - FREQUENCY +/- 2% The IDENTIFICATION PLATE shows maximum ABSORBED POWER (in Ampères), with respect to which, the power protection appliances required by applicable standards (not supplied with the station) must be sized. The maximum absorbed power refers to intended-use operation - DISPENSING OF DIESEL FUEL - with power supply within the above-mentioned limits. G4 HYDRAULIC PERFORMANCE When correctly installed and powered, and used for the purpose for which they were designed - DISPENSING OF DIESEL FUEL - the CUBE MC stations perform as follows: - Model CUBE MC: FLOW RATE MAX 70 litres/minute The installed pumps ensure CONTINUOUS operation of the stations. G5 CONTROL SYSTEM PERFORMANCE The performance of the MC control system is detailed in the M0103 manual supplied together with the CUBE MC. G6 METERING ACCURACY Thanks to the PULSER K600 METER and to the MC control system which ensures precise CALIBRATION, the CUBE MC stations provide the following performance: ACCURACY: +/- 0,5% 10 (after calibration, for flow rates above 5 litres/minute). (Translated from Italian) EN H INSTALLATION H1 GENERAL CUBE MC can be installed outside. Nevertheless, it is advisable to locate it under the shelter of a roof to ensure the dispenser's longevity and provide greater comfort during refuelling in the event of bad weather. The installation of the dispenser must be carried out by skilled personnel and performed according to the instructions provided in this chapter. Whenever CUBE MC is not installed under cover, a "display cover" is provided to protected the display and keyboard. ! ATTENTION The motors are not of an anti-explosive type. DO NOT install CUBE MC in places where there is risk of explosion. The CUBE MC stations can be connected both to tanks above ground and tanks under ground. H2 STATION POSITIONING The positioning of the SELF SERVICE must be such that it is possible to: - Easily remove the panels to access the inner components when necessary. - Observe the distances and maximum differences in level between the station and the tank. - Securely fasten the casing to the ground on a horizontal surface. Station positioning determines the following parameters, which distinguish each installation: Hp: Priming height Ls: Total length of the suction pipe - from the foot valve to the station (expressed in metres) To ensure correct station operation, the following limitations must always be kept to: Hp max: not over 3 metres LS max: not over 15 metres H3 MECHANICAL INSTALLATION Before starting installation, make sure no packaging materials are trapped in the pipes. Prepare suitable stilts or fixing brackets depending on the fixing position of the CUBE MC. The tube coming from the tank must be aligned to the threaded inlet of the pump filter which is located under the CUBE MC. TANK ABOVE GROUND TANK UNDER GROUND 11 EN (Translated from Italian) H4 HYDRAULIC CONNECTIONS SUCTION LINE The diameter of the "Ds" suction line must be selected according to the station model and the position of the station with respect to the tank. With reference to the "Hp" and "Ls" values indicated at point H2, the following MINIMUM DIAMETERS of the suction pipe must always be ensured. H4.1 MAXIMUM LENGTH OF THE SUCTION PIPES The maximum length of the tubing, the diameter of the tubing, the difference in height, are parameters that are tightly linked to creating suction conditions. The latter must not be such as to create backpressure greater than 0.6 bar. It follows as a consequence that, after respecting the minimum diameter of the tubing specified in the "Recommendations and Warnings" below, the length of the tubing decreases as the difference in height that the diesel fuel must overcome increases and vice versa: in fact, the back pressure progressively increases by 0.08 bar for every meter increase in the static height of the pump with respect to the level of the diesel fuel in the tank. RECOMMENDATIONS AND WARNINGS: - The suction pipe must resist a pressure of at least 10 bar and must be of a diameter NOT LOWER THAN 1'' 1/4. - The tubing must be suitable to functioning under backpressure. - Use tubing and accessories suitable for use with diesel fuel. Materials that are not suitable for use with diesel fuel can cause damage to the pump, harm people and cause pollution. - Any curves in the suction pipes must be of the widest radius possible to limit the loss of head. - Make sure that the suction pipe is clean and free of scum. ! ATTENTION In all cases, always take the following PRECAUTIONS: - Use pipes and connections suitable for vacuum operation. - Use pipes and accessories suitable for use with diesel fuel. Materials that are not suitable for such use can cause serious damage to the pump or injury to people; they can also be the cause of pollution. - Do not use conical threaded connectors that could cause damage to the threaded connector on the pump filter. - Use large-radius bends so as to reduce flow resistance to a minimum. - Make sure that the suction pipe is clean and free of scum. - At the end of the suction pipe, always fit a FOOT VALVE complete with FILTER. The valve must be placed on the bottom of the tank and be of the SAME DIAMETER as the pipe. - Before starting installation, make sure no packaging materials are trapped in the pipes. H5 ELECTRICAL CONNECTIONS The power connections must be workmanlike performed by skilled personnel, in strict compliance with the laws applicable in the country of installation and with the instructions on the wiring diagrams in this manual. Maximum acceptable electrical parameter variations are ±5%. ! ATTENTION The CUBE MC dispenser does not feature overload cutouts and, consequently, a switchboard must be fitted upstream of the CUBE MC complete with residual current circuit breaker suitable for the type of CUBE MC to be installed. 12 (Translated from Italian) EN CUBE MC features a terminal board cover. Inside this cover are the terminals which the installer must connect up to: - The mains power line - The RS 485 data line to the PC (optional). The connector block, accessible through the front panel opening, is already wired up to the CUBE MC components, according to the block diagram shown below. 1- Remove the right terminal board cover. 2- Connect the cables as shown in the diagram. 3- Close the terminal board cover box again. NOTE: The parts indicated in the diagram are the only connections to be made by the customer: - Connection to power mains. - RS485 output to PC (OPTIONAL). ! ATTENTION For CUBE MC commissioning, no further power connections are required. All the electronic components housed in the MC BOX are already wired up and factory tested. It is therefore NEVER necessary for the installer or station manager to open the MC BOX except to replace the protection fuses housed on the I/O card (see photo below). ! ATTENTION The installer should carry out a plug/socket connection for a quick sectioning of the electric system in case of failures. 13 EN (Translated from Italian) KEY: 1 Key reader (I-Button) 2 Display card 3 CPU card 4 Keyboard 5 I / O card 6 Jumper 7 Electrical boxes Below are the main connections and the fuses to be replaced by skilled service technicians only. 14 (Translated from Italian) EN I COMMISSIONING To correctly commission the CUBE MC the sequence of operations indicated below must be followed and the MC control system functions must be known (see attached manual). I1 ELECTRICAL POWER SUPPLY Once the power connections have been made, the CUBE MC can be energised by means of the master switch to be fitted by the installer on the upstream line. Switching on of the MC system will be indicated by the lighting up of the two backlit LCDs fitted on the front. Even when the nozzle is taken out of its seat, the pump WILL NOT start as it has not been enabled by the MC system. I2 WETTING THE PUMP CUBE MC features a self-priming pump that makes first startup easier. To start the appliance, the suction pipe need not therefore be completely full of diesel fuel. For quick priming, especially in the case of installations distinguished by a considerable difference in level between the pump and the tank, it is however important for the pump to be "wetted", meaning that there must be a small quantity of diesel fuel inside the impeller chamber. The pump is supplied adequately "wetted" and ready for use. If however the installer considers the pump to be totally dry, perhaps due to prolonged storage, he will have to wet it as he thinks best. I3 STATION CONFIGURATION Every CUBE MC station can be adapted to the specific requirements of the station manager. To do this the MC control system must be CONFIGURED. ! ATTENTION MC configuration is crucial and must be done by skilled personnel. To perform this operation, the MC manual must be carefully and thoroughly read. After completing configuration, user PIN CODES can be assigned to the persons charged with using CUBE MC, in accordance with the detailed information in the MC manual. I4 DISENGAGING THE "MC" SYSTEM All the CUBE MC functions are controlled by the MC control system. The MC system can nevertheless be disengaged for any startup or maintenance activities requiring repeated pump starting. In these case, it is often convenient to simplify pump startup by not having to enter any code and record any dispensing data. To do this, a JUMPER has been fitted on the card that permits switching from AUTOMATIC mode (code request to access dispensing) to MANUAL mode (no code request). 15 EN (Translated from Italian) ! ATTENTION The jumper is only accessible by opening the front panel and is positioned as shown in the photo. In this operating mode, MC does not record any data relating to performed dispensing operations. BEFORE ACCESSING THIS JUMPER, ALWAYS INTERRUPT THE POWER SUPPLY In MANUAL mode: • The MC LCDs could be off or continue to display whatever was showing at the time of switchover from AUTO to MAN. • To start the pump, no PIN CODE is required; the pump will start as soon as the nozzle is taken off its seat and will stop when the nozzle is put back. • The quantity dispensed by CUBE MC is not indicated in any way. I5 FIRST PRIMING To prime the pump: - Take the nozzle off its seat - Enter the previously assigned PIN CODE (if the jumper is on) - Lift the control lever - The pump will start immediately and will continue running indefinitely until the control lever is moved to OFF position. ON Position OFF Position Operate the lever of the automatic nozzle, keeping the spout inside an adequate container or the same suction tank. Air will first of all come out of the nozzle and then DIESEL FUEL will gradually begin to flow. ! ATTENTION The first priming of the pump must be done by skilled personnel who must monitor all the various stages involved. If only air continues to come out after more than two minutes, STOP THE PUMP and make sure: 16 (Translated from Italian) EN • This is not working dry, but is at least "wetted" with diesel fuel. • The suction pipe prevents any air from infiltrating and that this is completely submerged. • The filters are not blocked. • The suction and/or supply lines are not blocked. • Installation (level difference, diameter and pipe length) is within the limits indicated at point H4. • The disconnection valve is closed. Continue dispensing until the flow is regular and air free. Position the control lever in OFF position: - The pump stops. Place the nozzle back in its seat. I6 METER CALIBRATION Before using the CUBE MC station, check the METER ACCURACY. For this purpose, proceed as follows: • Enter a previously enabled USER PIN code. • Run the fuel into a calibrated container. • Compare the quantity of dispensed diesel fuel using a calibrated container. If accuracy is NOT satisfactory, proceed to CALIBRATE THE METER according to the instructions in the specific manual. ! ATTENTION To correctly check accuracy, always keep to the following instructions: • Use a precision sample container, featuring a graduated scale, with a capacity of at least 20 litres. • Before making the check, always make sure you have eliminated all the air from the system and then run the fuel until a full and regular flow is achieved. • Dispense continuously at CUBE MC maximum flow rate • Stop the flow by quickly closing the nozzle. • Reach the graduated area of the sample container, avoiding prolonged dispensing at low flow rate, but rather performing short dispensing operations at maximum flow rate. • Compare the reading provided by the container, with that provided by CUBE MC, after waiting for all the froth to disappear. ! ATTENTION Differences of up to 1/10 of a litre affecting the dispensing of 20 litres of fluid fall within the guaranteed accuracy of +/- 0.5%. 17 EN (Translated from Italian) L DAILY USE Thanks to the MC control system, all the CUBE MC models provide access to authorised users only. MC acknowledges User authorisation by means of two alternative systems: - The entering of a 4-figure SECRET CODE (PIN CODE). - The fitting of an electronic key (OPTIONAL). ! ATTENTION All the users to whom a PIN CODE is assigned must be adequately instructed and be at least acquainted with the contents of this chapter. The configuration of the MC system permits requiring the User to enter further optional data (vehicle licence plate, mileage, quantity to be dispensed). See MC manual (M0103) for details. If these options are not set, MC recognises an authorised PIN CODE and immediately enables the pump to dispense fuel. ! ATTENTION Such enabling does not result in immediate pump startup. The pump is in fact controlled by a switch (positioned in the nozzle seat) operated by the user. The pump will start (if previously enabled) just as soon as the control lever is moved to ON position, while it switches off as soon as the control lever is moved to OFF position. No further manual operation is required to start or stop the pump. L1 FUEL DISPENSING ! ATTENTION Fuel MUST ONLY be dispensed under the careful control of the User. In the case of the simplest configuration (no optional data required), the fuel dispensing procedure is the following: 1 18 Enter PIN CODE If the MC recognises an authorised code, it displays the following messages and enables the pump. (Translated from Italian) EN 2 Move the control lever to ON position (see photo on page 16) MC operates the pump. ! ATTENTION Never operate the nozzle lever before placing this in the fuel container 3 Operate the nozzle lever to start the dispensing operation MC indicates the dispensed quantity. ! ATTENTION The dispensing operation can be interrupted as required. If the interruption continues for over a certain time (which can be set as required by the station manager during MC configuration) the pump is stopped and disabled. To continue dispensing fuel, the various steps will have to be repeated starting from no. 1. 4 After terminating the dispensing operation, rewind the hose around the hose carrier, move the control lever to OFF position and put the nozzle back in its seat. MC stops the pump. ! ATTENTION If there is a power cut or the pump stops, the operator has to put the nozzle back in the unit seat. Remember that the nozzle can be opened only when the spout is in the tank. M ROUTINE MAINTENANCE CUBE MC has been designed so as to require minimum maintenance. For utmost station efficiency and safety, the following inspection and ROUTINE maintenance operations should however be regularly performed. M1 - OPENING AND CLOSING THE CUBE MC Lower the display cover Loosen the 2 screws on the right side (marked by the arrows) Open the inspection side of the CUBE MC To reclose it, perform these steps in reverse order. M2 PUMP AND PIPES Check the pump, the pipes and other internal components of the station and keep them clean. Make sure there are no leaks in the flanged or threaded connections and that the hoses are in perfect condition (not damaged) - refer to the Panther M0042 and K600, M0147 manual. 19 EN (Translated from Italian) M3 DISPENSER PIPE AND NOZZLE Keep the dispenser pipe and nozzle clean and make sure especially that: - The pipe is in perfect condition and has not been damaged by vehicle transit. - The threaded connections are tight and not leaking. - The swivel connections (at dispenser exit and on the nozzle) are turning freely and do not show leaks. - Keep the dispensing tube and nozzle clean and check that the automatic stop feeler hole at the end of the spout is always clean. SWIVEL CONNECTIONS FLANGED CONNECTIONS PROBE HOLE AUTOMATIC STOP (SPOUT) M4 "MC" CONTROL SYSTEM The MC system is maintenance free. To control it however, refer to the dedicated M0103 manual provided. M5 FILTERS CUBE MC features a number of filters having different functions. The inspection and cleaning (or replacement) of each filter is crucial to ensure: - The protection of the various station components (pulser, pump, nozzle). - Station performance remains high over the years (maximum flow rate). - Protection of the engines using the dispensed diesel fuel. ! ATTENTION Dirty or partially blocked filters can increase flow resistance and cause a considerable reduction in the maximum flow rate of the pump. Dirty or blocked pump suction filters also cause a big increase in vacuum during suction and this in turn can make the pump particularly noisy. 20 (Translated from Italian) EN M5.2 PUMP FILTER This is fitted in the pump body, as a standard PANTHER pump fitting. To inspect and clean it: 1 Loosen the two filter cover screws and take the cover off. 2 Take out the mesh filter with the aid of a pair of pliers. 3 If the filter needs cleaning, wash and blow it. 4 Put the filter carefully back in its housing in the pump body, making sure it does not protrude from the cover housing. 5 Check and clean the flat seal, reposition the cover and tighten the screws. M5.3 PULSER FILTER The pulser filter represents a further protection against the risk of foreign bodies entering the oval-gear pulser. Because this filter is fitted downstream of the pump suction filter, it does not require regular inspection and cleaning. Should the need arise however and/or in case of special maintenance, it can be cleaned as described in the PULSER MANUAL, after removing the roof of CUBE MC (if necessary) by means of its relevant upper screws (see exploded view, pos.14). M6 PULSER The meter / pulser is a carefully-made and assembled high-precision measuring instrument. It normally requires no routine maintenance. CALIBRATION, normally done during station installation, can be repeated whenever accuracy checks, to be performed every 3/6 months, show the need. CALIBRATION is done electronically by means of the MC control system, and does not require any adjustments to be made to the pulser. For all details, refer to the K600, M0147 meter manual. 21 EN (Translated from Italian) M7 TROUBLESHOOTING PROBLEM POSSIBLE CAUSES Lack of electric power THE MOTOR IS NOT TURNING Fuses burned out Motor problems MOTOR WON'T START WITH NOZZLE CLOSED Check that the voltage is not more than 5% below the nominal voltage Excessive suction pressure Lower the CUBE MC with respect to the tank or increase the diameter of the tubing High loss of head Use shorter tubing or of greater diameter Raise the suction pipe Refill the tank Air entering the suction pipe or in the pump Check the connections seal in the tubing and the level of diesel fuel in the tank Motor low rotation speed Check the voltage at the motor: adjust the voltage and/or use cables of greater cross-section Check valve blocked Tank filter clogged Pump filter clogged Fluid leaking Meter chamber obstructed Air in the suction line METER NOT ACCURATE ENOUGH Lack of calibration THE NOZZLE TRIPS Automatic stop probe hole TOO OFTEN blocked 22 - Make sure the operating lever is in ON position - Recock the external residual current circuit-breaker - Check the electrical connections Change the fuses on the switchboard If the rotor is jammed, dismount and check for damage and obstructions, then remount.
