2.4 The GA8500 Power Management System
The GA8500 is designed to operate directly from a clean 12Vdc power
supply, as supplied in standard agricultural machinery. The power
supply system will operate in the range of 9 to 16V dc and provide a
clean continuous 12Vdc for the internal processors.
Furthermore the GA8500 power management system has been
designed to operate (start / stop) in an intuitive way for the user. By
default the system will be started and stopped using the Power Control
switch as shown in Figure 2-2. However the GA8500 can also sense
(optional power cable required) when the vehicle is started and stopped,
and cause the GA8500 to start and stop respectively.
While the power supply has been designed to operate in a wide range of
voltages, the GA8500 should not be started while cranking the vehicle’s
engine as this will cause erratic voltages.
2.4.1 The GA8500 Power Control Switch
The GA8500 detects when DC power is connected to the systems and
emits two short beeps. This will not start the system.
Press the Power Control button, as shown in Figure 2-2, to start the
system and one long beep will be heard. Release the button and the
GA8500 will start to operate. Several screens will be displayed during
the start up process, these are described in Section 3.1
If the button is held down for a longer period, two shorter beeps will be
heard. This indicates that the system will start up in Launcher mode, see
Section 3.4 for further details. If Launcher mode is accidentally started,
select the top option “Start GuideTRAX” to return to normal operation.
To turn the GA8500 Off, press and hold the top panel power button until
one beep is heard. The system will display a shutdown progress screen
while it is saving data and settings. At the completion of this process,
power will be removed from the system.
2.4.2 The GA8500 Ignition Sense Switch
The GA8500 can be configured so that it will start and stop as the
vehicle’s engine is started and stopped. This is convenient for some
