OPERATING INSTRUCTIONS FOR THE VDO DIGITAL TACHOMETER
The VDO digital speedometer installed on the machine has been factory programmed. This instrument can read
instantaneously the hose rewinding rate and show this on the display as meters per hour.
The display also gives the first decimal for the speed and the current time. Speed range is from 5 to 140 m/h.
This instruments works with a 3V battery (Type CR 2032/Sony) with a working life of around 2 years.
The instrument is automatically switched on when the hose is reeled in or out. To prevent the battery from be run
down, the liquid crystal display will automatically switch off about 5 minutes after the machine is stopped.
FUNCTIONS AND OPERATION
ACTUAL SPEED DISPLAY
The digital tachometer displays the temporary rewinding speed. This function is always activated on the VDO
SPRINT instruments (oval MODE key and red round SET key) and on the VDO CYTEC C05 instruments (one
key only).
To display the current time with VDO SPRINT instruments, press MODE key, for at least 2 seconds. With the
VDO CYTEC C05 instruments, press once or more the key to display CLK. The display will show the current
time, the symbol CLK and the temporary rewinding speed.
With the VDO EURO instruments (rectangular MODE key), the temporary speedy is activated only when the
symbols SPD and CLK besides the current time are displayed; if this is not the case, they can be activated by
pressing MODE key until both symbols are displayed.
The displayed speed is perfectly correct only when the pipe is completely unwound until the last layer; when the
pipe is completely wound, the displayed speed is slightly low than the real one.
CHANGING THE BATTERY AND PROGRAMMING THE INSTRUMENT
If the battery has to be changed (display off), follow these steps:
1. Remove the display from its mounting as shown in figure 2. Use your right hand to push the instrument
down and use your left thumb to press the black knurled button under the instrument to release it from its
mounting.
On VDO Cytec C05 puss slightly the head and turn it counterclockwise, then remove the head from its
holder.
2. Use a coin to unscrew the battery enclosure cover. Remove the battery and replace it with the new one
(Fig.3).
Insert the new battery with the positive pole towards the top and replace the cover. When the battery is
changed the data remain in the memory for about 15 seconds.
WARNING! Batteries are special waste material to be disposed of correctly.
3. If the data are cancelled, reprogram the instrument as follows:
VDO EURO AND VDO SPRINT INSTRUMENTS:
Press MODE key until the ODO function appears on the display. Press SET key for at least 3 seconds. Insert the
requisite number for the machine model (see table at page IV.12).
Press MODE key to select the first number on the right of the display. Set it with SET key. Follow this process for
all the numbers until they no longer flash.
On the model VDO SPRINT, press again SET key for at least 6 times, until the temporary rewinding speed is
displayed, then press MODE key for at least 3 seconds to display the current time too.
