Configuring Engine Hours
ALEOS can keep track of Engine Hours and how long the engine has been on,
which is determined by either Ignition Sense or the Power In voltage. In the Low
Power group, under Common, there two configuration fields to govern how
Engine Hours is determined.
• Engine On Voltage Level (.1 Volt) - Use the PowerIn voltage to monitor
engine usage. Set the voltage to higher than the maximum “at rest” voltage of
your battery to track how long the device has power.
• Engine Hours Ignition Enable - Use ignition sense to monitor how long the
engine has been on.
A typical battery will be below 13.0 Volts, while a typical vehicle maintains the
voltage at 14.4 volts. So a value of 130 (13.0 Volts) will identify when the engine is
on, correctly.
Command Description
Voltage Levl Low
Power Enable (.1Volt)
Set or query the voltage level at which the device goes into low power mode.
• Ignore voltage for power control.
• threshhold in tenths of volts
Example: ATVLTG=130 would place the device in a low power use, standby state if the
voltage goes below 13.0V.
Note: When Ignition sense is enabled, there is no no need to configure this parameter with
ignition sense enable.
Low Power Mode
Delay (Minutes)
Number of minutes after one of the power down events (VTLG or DTRP) happens until the
AirLink device enters the low power mode. If DTRP and VLTG are both 0 (zero), this setting
does nothing.
• n=0-255 minutes
Note: There is always a minimum of 1 minute between power down event and actual
shutdown (to give the AirLink device time to prepare); entering zero will not power down
the device immediately, but after one minute.In the first 5 minutes after AirLink device
powers up, power down events are ignored to give the user time to change configurations.
Standby Ignition
Sense Enable
Standby Ignition Sense Enable: the AirLink device will monitor the ignition sense on the
power connector and enter the low power consumption stand-by mode when the ignition is
turned-off.
• n=0 : Disable
• n=1 : Enable
Engine Hours on
Voltage Level (.1
Volt)
Set the voltage above which the Engine should be considered "ON".
To enter a voltage of 13.0 volts, enter 130.
Engine Hours Ignition
Enable
Engine Hours will be counted when enabled.
