SPIDER MAX 500
The alarm is displayed with any function displayed.
• While the warning message is on (60 sec.), the button function is disabled.
• While the warning message is on(60 sec.), the only functions that persist on the display are
"Fuel"(fuel level indicator), "wtemp" (radiator coolant temperature) and "hydraulic stand alarm" (when present).
• The alarm is displayed with any function selected.
3.5 Battery low alarm (VBATT)
When the battery charge is below the programmed threshold value the system starts the alarm routine. The battery icon
is displayed along with the message LOW on the upper right hand side of the display (F. 1). This alarm signal does not
affect the normal operation of the dashboard and is displayed with any selected function (in case the selected function
is "Preventive Maintenance", only the battery icon is displayed - F. 4). The alarm situation ends when the charge exceeds
again the threshold value.
3.6 Simultaneous alarms
In case of simultaneous alarms a different class of priority is given to each type of alarm described in the previous
sections. More precisely the "hydraulic stand" alarm is given Priority 1 (the highest), while the OIL LOW PRESSURE and
ICE alarms are given Priority 2 (lower than the previous one); the OIL CHECK/CHANGE and V. BELT CHANGE alarms
are given Priority 3 and the "battery low" alarm is given Priority 4 (the lowest). The table below shows the different
classes of priority:
Imagining that all the types of alarm occur together, the system will act as follows:
• The "hydraulic stand" alarm icon is always displayed, no matter if any other alarm is on.
• The warning message OIL LOW PRESSURE and ICE alternates every 5 seconds, while all the other alarms (OIL
CHECK/CHANGE, V.BELT CHANGE and battery low) are set in the memory queue.
• After the ICE alarm (which lasts only 15 sec.), only the OIL LOW PRESSURE is displayed while all the other alarms
(OIL CHECK/CHANGE, V.BELT CHANGE and "battery low") are set in the memory queue. In case the OIL BAR alarm
(pressure switch opened or Rpm=0 rev./min.) only the ICE alarm is displayed while all the other alarms (OIL CHECK/
CHANGE, V.BELT CHANGE and "battery low") are set in the memory queue.
• Only when the two alarms with Priority 2 (OIL LOW PRESSURE and ICE) go off, the system starts managing the
alarms with Priority 3 (OIL CHECK/CHANGE and V.BELT CHANGE), alternating them every 5 seconds for a total
duration of one minute each. The alarms with Priority 4 ("battery low") are set in the memory queue.
• Only when all the alarms with Priority 3 (OIL CHECK/CHANGE and V.BELT CHANGE) go off, the system starts
managing the alarms with Priority 4 ("battery low") that are displayed according to the methods above described.
• After the alarm sequence is over, the system restores the display normal operation mode.
While the alarms with Priority 2 and 3 (ICE, OIL LOW PRESSURE, V.BELT CHANGE and OIL CHECK/CHANGE) are
on, the button function is disabled.
