DIGITAL INSTRUMENT PANEL (WHERE FITTED)

USEBUTTON FUNCTIONS

The button can be used to:Move from one function to another.Set the trip meter, chronometer and average velocity display to zero. Alter the wheel circumference value, the unit of measurement and the number of pulses per wheel turn or engine revolution.

It is always possible to pass from one function to another, regardless of the status of the machine – in movement or halted. The only thing required is to press the button briefl y (1 second),and on releasing it, the new screen appears with the new function.Zeroing of the trip meter, as well as adjusting the chronometer and average speed display can be carried out with the machine either halted or in motion, in accordance with the procedures described in the following paragraphs.The CONFIGURATION menu can only be accessed with the ma-chine halted, by positioning in TOD function and holding the button down for 5 seconds.Data will only be memorised by leaving the confi guration menu by means of the mode button.

SUCCESSION OF THE FUNCTIONS

It is always possible to pass from one function to another, either with the machine halted or in motion, by using the button and in the follo-wing sequence:

ASSOCIATED FUNCTIONS

RYZ

FUNCTIONS OF THE MAIN MENUCURRENT SPEED

The information is always displayed in large electronic digits (see fi gure), regardless of the function selected or the alarm active.The information is displayed on screen every 0.5 seconds.

Representation of the current speed data:Representation in kph (original confi guration): in this case, the “km/h” logo will be displayed.Representation in Mph (See “Altering the unit of measurement” in CONFIGURATION): in this case no logo will be displayed.

TRIP (TD)

This is an automatic onboard partial totaliser.This function is always displayed in small digits accompanied by TD.The data displayed indicates the distance travelled by the machine expressed either in km or in miles (depending on the measure-ment unit selected), with a resolution of 0.1 (km or miles).It is an automatic meter which is activated autonomously by the fi rst pulse coming from the speed sensor.The data is not memorised permanently.The meter associated with this parameter can be zeroed by hol-ding the button down (in relation toTOD function) for approx. 3 seconds, until the value “000.0” appears. Zeroing this meter also zeroes the lAP and AVE functions.If the data exceeds the 999.9 fi gure, the system returns the TD, LAP and Ave to zero and begins to count again.

AUTOMATIC CHRONOMETER (LAP)

This is the chronometer related to the TD and AVE.The information is displayed in small digits and accompanied with LAP.The data represents the real time of the distance covered by the machine associated with the TD parameter (in the mm:ss format if the hour=0, and in the hh:mm format if the hour>0).

It is an automatic meter:It is activated autonomously by the fi rst pulse coming from the speed sensor.When LAP is operative, the digit separating the hours from mi-nutes or minutes from seconds is displayed fl ashing, whereas it is unfl ashing when LAP is not operative.

CAUTION:When there is no current present, the TD value will be irremediably lost.

RYZ


3) It stops 3 seconds after the reception of the last pulse from the speed sensor.

The data is not memorised permanently. The meter can be zeroed by holding down the button (in relation to the LAP function) for approxi-mately 3 seconds, until the “0.0” value appears.Zeroing this meter, either with the machine halted or in motion, also causes the zeroing of the TD and AVE functions.If the data exceeds the 23-59 value, the system returns the TD, LAP and Ave to zero and begins to count again.

AVERAGE SPEED (AVE)

The information is displayed in small electronic digits, accompa-nied by AVE, which indicates the function selected.The data represents the average speed maintained by the machi-ne (expressed in km/h or in Mph, depending on the unit of measu-rement selected), calculated as the proportion between the distan-ce travelled (represented by TD) and the time needed to travel the distance (represented by LAP); the average speed is calculated every 0.1 km (or 0.1 miles depending on the unit of measurement selected) travelled by the machine.The data is not memorised permanently. The counter associated with this function can be zeroed by holding the button down (in relation to the AVE function) for approx.3 seconds, until the 0.0 value appears.Zeroing this meter, either with the machine halted or in motion, also causes the zeroing of the TD and LAP functions.The AVE meter is also zeroed when LAP reaches the “23:59:59” value, or when TD reaches the “999.9” value.If the data to be displayed exceeds the 409 value, the character “----” will be displayed.

3)

CAUTION:When there is no current present, the LAP value will be irremediably lost.

6

CAUTION:When there is no current present, the LAP value will be irremediably lost.

RYZ

TOTALISER (TOD)

The information is displayed in small electronic digits, accompa-nied by TOD, as can be seen in the fi gure.The data is memorised permanently in a non-volatile memory (up-dated with every kilometre travelled).If no data appears registered in the memory, the number “00000” will be displayed.The information is always calculated in km. However, it can be expressed either in km or in miles. The conversion is possible by accessing the confi guration menu.In normal use instrumentation conditions, it is not possible to zero this information.

REV-COUNTER (RPM)

The information is displayed in small digits and accompanied by an indication along the graphical bar and the inscription “RPM” next to this.The data is displayed in revolutions per minute.The value is updated every 0.5 seconds.The resolution is a constant 100 rpm over the whole scale.Scale background value: 12,000 rpm.The number of pulses for each engine revolution can be selected by accessing the confi guration menu.The graphical bar, updated every 0.5 seconds, is interpreted in accordance with the following table:

BATTERY VOLTAGE ALARM

When the voltage value is lower than or equal to 12.0v, the system activates the alarm.The indication consists of fl ashing the battery symbol and displa-ying the inscription “MIN” (regardless of the function being displa-yed).This alarm does not affect the normal functioning of the instrument panel.The state of alarm ceases when the voltage returns to 12.5v.Thus, the entire sequence is repeated every time the voltage is lower than or equal to 12.0v, and is interrupted every time the voltage is greater than 12.5v.

SLEEP MODE

Every time the key switch is turned to the OFF position,the following operations take place:

The screen and its lighting are switched off.All the indicator lights that were on are turned off.Entry into “sleep” phase, characterised by a low current con-sumption, in which the system interrupts every activity.

CONFIGURATIONThe confi guration menu can only be accessed with the machine halted.Holding the mode button down for approximately 5 seconds acce-sses the TOD function, and the confi guration menu is displayed. This menu allows the user to alter the following parameters:

the circumference of the wheel (minimum 1,000 mm, maxi-mum 2,500 mm).Unit of measurement (Km/h or Mph).Number of pulses coming from the speed sensor for each turn of the wheel (minimum 1, maximum 12).Number of pulses for each engine revolution (minimum 1, maximum 6).

To ensure that the alterations made in the confi guration menu are consolidated, the user needs to run through the entire sequence of screens envisaged in this menu, making sure to exit the confi gura-tion menu (and re-establishing the standard operating mode). To re-establish the standard operating mode, keep the mode button held down in the last screen, regarding the number of pulses per engine revolution (which is the last menu confi guration screen), until the apparatus returns to the standard operating mode.

If the confi guration menu is exited by:putting the machine in motion,turning the ignition key,or not holding the button down for 20 seconds, the alterations made will not be registered and the system will return to the preceding values.

CAUTION:The system will only permanently save the changes made when the confi guration procedure is carried out correct-ly.

RYZ

ALTERING THE WHEEL CIRCUMFERENCE

Once inside the confi guration menu, the fi rst parameter that can be altered is the wheel circumference.

The screen displays the only information seen, which is the cir-cumference of the wheel, whereas all the other segments are off.The different fi gures that make up the wheel circumference value can be altered, starting with the most signifi cant fi gure and moving successively to the least signifi cant.

Depending on the detail selected (which will be displayed fl ashing), a brief press of the button will cause the fi gure to rise by one unit, while a longer press will enable changing to another fi gure.The information regarding the wheel circumference selected is stored in memory.

ALTERING THE UNIT OF MEASUREMENT

Once the wheel circumference regulating has been completed, it is possible to alter the unit of measurement by pressing the button for approximately 3 seconds.Once the least signifi cant fi gure has been altered: at this point the two inscriptions “km/h” and“Mph” will appear on the screen, and at the outset the selected value will fl ash.The procedure for changing the unit is identical to that described in the previous section.The information regarding the unit of measurement is stored in memory.


6

CAUTION:• Regulating interval: from 1,000 mm to 2,500 mm with intervals of 1 mm.• Once the regulating menu has been accessed:- if 20 seconds go past without the button being pressed, or- if the machine is started up, or- if the key switch is turned to the OFF position, the sys-tem will automatically return to standard operating mode, and the changes made will be lost.


RYZ

ALTERING THE PULSES PER WHEEL TURN

Once the unit of measurement has been selected ( it appears fl as-hing), press the mode button for 3 seconds. It will then be possible to alter the number of pulses for the wheel.This parameter expresses the number of pulses which the elec-tronic sensor sends to the instrument panel for every turn of the wheel.This information is stored in memory.

ALTERING THE IMPULSES FOR EVERY ENGINE REVOLUTION

Once the alteration made in the previous screen is completed, the button must be held down for 3 seconds, and then it will be possi-ble to alter the number of pulses for every engine revolution.This parameter expresses the number of pulses for each revolu-tion of the engine’s primary drive shaft that the machine is able to send to the instrument panel.This screen can be distinguished from the previous one by having the logo “RPM”.This information is stored in memory.



RYZ

STARTING THE SYSTEMOn switching on (key from OFF to ON), the system provides the user with a series of data, which, in order to simplify things, are shown on different screens in the form of pages:

First page: software version and date. This information only appears during the fi rst instrument panel installation.

2) Second page: glass check; all the glass segments remain lit up for 3 seconds.

Third page: wheel circumference, measurement unit (only in the case of km/h), number of pulses for each turn of the wheel and number of pulses for each engine revolution (see fi gure).

At the same time as displaying the aforementioned screens, the system also checks the indicator lightsand the glass backlighting: all the indicator lights come on and then go off at the end of the screen check.Once all of this has been completed, the system displays nor-mal view.

FIRST INSTRUMENT PANEL INSTALLATION

The values that the instrument panel has registered by default are:

Wheel circumference: 2,205 mm.Unit of measurement: km/h for speed and km for distance.

Pulses per turn of the wheel: 1.Pulses per engine revolution: 1.To alter any of these parameters it is necessary to follow the steps described in the CONFIGURATION part of this section.

N.B.:During the fi rst instrument panel installation, the version and date of the software incorporated always appear on the screen.
