[. . . ] It must also have Internet Explorer 5. 5 or better. When a new version of the software is installed, it is recommended that the old versions are uninstalled completely and the new cd-roms used. The new cds contain a package "EncPak IE" with a file "Install. htm". This file contains the correct links to further files on the cd-rom which allow updating of computers with the Internet Explorer files needed to proceed with the programming of the control boxes. [. . . ] The modification of parameters 1, 4, 5 and 6 must take place as shown in line 10 with key removed and commutator off. In the event that modifications are made without the commutator being off, they will only be visualised, and at the next disconnection/connection with the control box they will be lost. 10 LANDI RENZO S. p. A. Software handbook 15 - WARNING!MODIFY THE PARAMETERS IN RED ONLY WITH LOCK REMOVED AND COMMUTATOR OFF 16 ­ STATUS BAR The status bar shows, from left to right: A ­ type of fuel being used; B ­ number of engine revolutions; C ­ time of petrol injection, time of gas injection; D ­ engine water temperature, gas temperature and gas pressure; E ­ voltage of Lambda sensor and rich (red) or lean (green) carburation of the vehicle while functioning (if the sensor is connected). 3. 1. 2 Lambda (optional) 1 2 Fig. 5 1 - TYPE OF LAMBDA SENSOR Allows setting of type of lambda sensor fitted to the vehicle, to obtain a correct interpretation of the signal. The following values can be set: A - 0 - 1 Volt; B - 0 - 5 Volt; C - 5 - 0 Volt; D - 0. 8 - 1. 6 Volt. 2 ­ NUMBER OF LAMBDA SENSORS If two Lambda sensors are fitted, allows setting and visualisation of both signals. Software handbook LANDI RENZO S. p. A. 11 3. 1. 3 Gas level 1 2 3 Fig. 6 1 ­ TYPE OF GAS LEVEL SENSOR Allows setting of the type of gas level sensor installed. The following gas level indicators can be set: A - A. E. B. ; B - 0 - 90 ohm; C - Landi Renzo; D - Non standard; E - Non standard inverted. The standard predefined setting is the Landi Renzo sensor. By selecting the option "NON STANDARD" or "NON STANDARD INVERTED" it is possible to customise the settings for the type of gas level sensor used by setting the relevant thresholds. 12 LANDI RENZO S. p. A. Software handbook 2 ­ AUTOMATIC RETURN TO PETROL If this control is activated, two conditions are possible governing the return to petrol: - the lower pressure read for a certain period (point 3 fig. In this case an automatic return to petrol takes place accompanied by an audible (fast intermittent buzzer) and visual signal (petrol and gas led lit up). 2 - PRESSURE This shows the gas pressure in bar. 3 ­ INJECTION TIME A - Gas Injection time on gas actuated by gas injectors. B - Petrol Petrol injection time read from the MULTIVOX OMEGAS control box via the injector disconnection wiring. Software handbook LANDI RENZO S. p. A. 23 4 - WATER TEMPERATURE, GAS TEMPERATURE, GAS INJECTOR VOLTAGE A ­ Water temperature Provides indications of the water temperature read from the sensor fitted to the "T" inserted into the engine cooling water circuit at the reduction unit inlet. B ­ Gas temperature Provides indications of the gas temperature read from the sensor fitted to the injector rail. C ­ Gas injector voltage Indicates the power feed voltage of the gas injectors. 5 ­ LAMBDA SENSOR This is the value in Volts supplied by the Lambda sensor (if connected). 6 - EXIT 24 LANDI RENZO S. p. A. Software handbook 3. 3 DIAGNOSIS 1 2 Fig. 17 The functioning diagnosis page allows the viewing of any possible malfunctions of components and system which may occur while functioning with gas. If an error is seen, after resolving the problem which caused the error, zero the system by pressing key 1. The malfunctions which may be indicated are: GAS INJECTOR DIAGNOSIS While functioning with gas an error is signalled on the corresponding injector if for a certain consecutive number of injections (10) situations of open-load or short circuit occur in the coil of that injector. LOW PRESSURE DIAGNOSIS While functioning with gas an error is signalled if the pressure read stays for a certain time (low pressure time for return, which can be set from Tools in the Gas Level page) at a level: - less than 0. 4 bar for normally-aspirated engines and 1 bar for turbo engines running on LPG - less than 1. 54 bar for normally-aspirated engines and 2. 6 bar for turbo engines running on Methane when at the same time the gas level is not on reserve. [. . . ] Each METHANRE or LPG archive is structured with an archive in the left part of the screen and organised as a hierarchical tree diagram on three levels. This means that to arrive at a particular vehicle model it is necessary to move around the tree, each time selecting the correct branch from those available. The first level corresponds to the type of fuel in use and is managed automatically by the software once the type of fuel is set in the page F1 CHANGE TO GAS in F1 VEHICLE CONFIGURATION. The second level corresponds to the names of the vehicle manufacturers, arranged in alphabetical order, so the branch corresponding to the manufacturer in question must be "expanded" (keys RIGHT ARROW or RETURN.
