User's manual – C6 ECON
40 Karl E. Brinkmann GmbH
Monitoring phase of the status of the power line by the applica-
tion dedicated to the UPS function.
The application accesses the information on the UPS unit via the
Smbus system bus. Any power outage during this phase will cause
the start of a countdown. If the countdown exceeds 2 minutes, the
shutdown procedure is irreversibly started. Brief power outages will
instead have no effect on continued PC operation.
Shutdown phase
This phase lasts a varying amount of time, not known in advance,
which is contingent upon the number and type of active applications.
When the line power supply comes back on during this phase, it
does not in any way affect the correct execution of the shutdown
procedure, which must in any case be completed. Upon completion
of this phase, if the line power has not come back on, the system will
shut off the power suppliers of the C6 ECON system, of the UPS
module via the Mpson signal, and it will place the machine in standby
status (return of line voltage)
The return of line voltage places the system back in START status.
Standby phase
Constant monitoring of the line voltage in which its return causes the
machine to restart. There are two specific cases:
• Shutdown desired by the user, in which the machine must shut
down even if there is mains power supply. In this case the ma-
chine can be turned back on by turning the line voltage off and
then back on.
• Shutdown caused by line voltage failure in which the UPS pow-
ers the machine until the shutdown sequence is complete. At this
point, both (C6 ECON and UPS) are de-activated. The machine
restarts as soon as the line voltage is restored (START phase). If
the line voltage is restored during the shutdown phase, the sys-
tem will start the machine again upon conclusion of this phase.
