“AUX/PROGRAM” first and then use “STOP”), each pressure decrements the value of 10
units.
The multifunctional display is the means to visualize measures, status indications, and
alphanumerical anomalies. The visualization is on two rows and sixteen columns.
The contrast level can be manually regulated by pressing the
keys “MODE/ACK” and
“AUX/PROGRAM” at the same time: if you first press “MODE/ACK” the contrast level
increases, if you first press “AUX/PROGRAM” the contrast level decreases. The regulated
level is stored in non-volatile memory and so it is preserved even if power supply is
disconnected. ATTENTION: the manual contrast regulation is available only from software
release 00.03. On some board is mounted a display with automatic contrast regulation: in this
case the manual regulation has no effects.
The display has an internal backlight, which allows the reading of the indications also in bad
light condition or at night.
The internal lamp is switched on pressing any key; its turn off can be configured with the
parameter P.492: it is the maximum working time (in seconds) of the lamp since the last key
was pressed. Setting the parameter to zero to leave the lamp always on.
NOTE: if the lamp is switched off, the pressure of a key causes only the switching on of the
lamp and doesn't involve the action predefined for the key: to obtain this action the key must
be pressed again.
While the engine starter is running, the lamp is automatically switched off to reduce the current
consumption of the board, in such a way to leave more energy to the board if the engine battery
voltage is low. When the engine is running (only if started by DST2600), the light is always
switched on to improve the readability of the display
The display foresees four visualization modes
, selected with the “MODE/ACK” key and
highlighted by the four LEDs on the right side of the display. Except for “MODE 1”, each mode
has more than one page: it is possible to select these pages with the “AUX/PROGRAM” key.
Passing from one mode to another, the display shows as first the last page visualized in that
mode.
