Application example
Below is an application example schematic of the CCpilot V700 power supply connection.
If the system has a main switch for completely disconnecting the battery (S1 in schematic
below), the device’s power supply and key switch signal shall be connected after the main
switch.
It is
not
recommended to disconnect the battery without shutting down the device first - since
doing so will immediately switch off all internal voltages, regardless of ongoing operations. Any
information which was not saved to flash memory will be lost when disconnecting the battery.
However, no physical damage will be caused to the device by disconnecting the battery.
Figure 7: Schematic example for power supply installation of a CCpilot V700 device in a
vehicle. The ignition switch (S2) can be shared by several devices (Device X, Y, …)
By connecting the power supply according to the example above, the CCpilot V700 device will
automatically start up when the key switch (S2) is closed and shut down when the switch is
opened.
Note that the on/off behaviour of the CCpilot V700 described here is the default configuration.
Its response to the on/off signal may be altered using the CCAux API, see chapter 5.1 for more
details.
Be advised that the device consumes a small amount of power from the main supply also when
shutdown (123 µA at 12V, 0.38mA at 24V) or suspended (37mA at 12V, 22mA at 24V).
Therefore, if the device has been attached for a long period of time without the vehicle motor
