If the engine is running below its gate value, the peak values are not
reset to the current values but are set to the values in the following
table:
Parameter
New Peak Value
Engine RPM
Current value
Wheel speed

Oil Pressure
999 PSI or 99.9 Bar
Oil Temperature
0C or 0F
Water Temperature
0C or 0F

Peak Value Memory
Peak Value Memory
The peak values are stored in a memory which is powered by an internal
back-up battery. They remain stored in this memory when the external
power source is disconnected from the system. The internal battery needs
to be changed every 4-5 years. When the power from this battery drops
below a safe level, an alarm is triggered and the warning "Internal
Battery Low" is displayed.
Alarms
Alarms
The Display System has built-in warnings to alert the driver when
certain parameters either exceed or fall below their alarm values. For
example, a warning is signalled if the oil pressure falls below its alarm
value or if the oil temperature rises above its alarm value. You can
adjust the preset alarm levels when you configure the Display System.
See Chapter 4, Configuring the Display System in this manual.
Some of the warnings (see the following table) are triggered only after
the engine speed has exceeded its "gate value" for RPM for at least one
second. Blipping the engine may not be enough to trigger a warning.
The gate value is a predefined RPM value that is used to control when
the system is to trigger a warning. This is to prevent abnormal warnings
