MoTeC Configuration 51
Alarms
Alarm Comparisons
The warning alarm limits are fully programmable and may include up to 6
comparisons to ensure that the alarms are only activated at the correct time.
For example, an engine temperature alarm may activate at 95 °C if the ground
speed has been above 50 km/h for 30 seconds. The speed comparison
avoids the alarm showing during a pit stop due to heat soak. Additionally
another comparison could be set at a higher temperature to cover all other
situations.
The comparison values can be automatically incremented or (decremented)
when an alarm occurs. For example the engine temperature alarm may be set
at 95 °C with and increment of 5 °C, so that the second time the alarm
activates at 100 °C. A limit may be set on the number of times the comparison
value is allowed to increment. An alarm may return to its original value after a
period of time, in case the alarm condition was temporary.
The alarms can be dependent on the current display mode page (Warm-up,
Practice or Race).
Alarm Behaviour
Alarms are either:
• Active and unacknowledged (alarm conditions are true).
• Inactive and unacknowledged (alarm condition was true but became
not true before alarm was acknowledged).
These will continue to display until acknowledged.
• Active and acknowledged (alarm conditions are true but not
displayed).
• Inactive (conditions needed to make an alarm active are not met or
true).
The following behaviour applies:
• Active and inactive unacknowledged alarms remain displayed until
they are acknowledged, either by the Acknowledge Button or
automatically after a defined period of time. After acknowledgement,
and if the alarm is still active, it may display again after the "do not
display message interval" has elapsed.
Note: If it appears that an active unacknowledged alarm cannot be
acknowledged (that is, it continues to display), it could be that the "Do
not display this message again until ... seconds have elapsed" is set
to zero.
