CarNetix PSU-PC12 V1.1 Installation Manual
3.2.2 Starting the PSU with a pulse
When the PSU is in Idle State (both LEDs off) and an externally applied pulse is applied
to the Pulse Start input, the PSU will power up normally, as it would if the Ignition line
had gone high. During the Bootup Lockout State any input pulse is ignored.
3.2.3 Stopping the PSU with a pulse
After the normal power up sequence, and while in Runs State, the SSC monitors the
Pulse Start input for a shutdown pulse. If a single shutdown pulse is sensed, the PSU goes
into the Shutdown Delay State. However, if control has been passed to the Ignition line
(see Ignition Override below) the Pulse Start input is ignored.
3.2.4 Prolonging the Shutdown Delay State
If, while in the Shutdown Delay State, a single pulse is detected, the Shutdown Delay is
restarted at its original value in order to prolong the Shutdown Delay. This is useful for
occasionally downloading large files that would take longer than the normal Shutdown
Delay time.
Once the Shutdown Delay has timed out, the PSU enters the Shutdown Lockout State. At
this point the SSC ignores any pulse input until the PSU enters the Idle State.
3.2.5 Shutting down the PSU with double pulses
If two pulses are detected within a 5 second window during the Shutdown Delay State the
PSU will skip any remaining Shutdown Delay Time and immediately enter the Shutdown
Lockout Sequence. This feature is useful for shutting down the Xenarc SC3 when your
file transfer process is completed.
3.2.6 Ignition Override
If, after the PSU has been started by a pulse, the Ignition is turned on, control is passed to
the Ignition line. Once the Ignition line has gained control of the SSC it will be able to
shutdown the PSU as if it had initially started it. This feature is useful when you wish to
remotely start the Xenarc SC3 with your wireless device, but then get into your car and
drive.
