 Lowpowerprotection
Toavoiddrainingpower,low‐powerprotectionistoensurethatthereisenoughpower
tostartthemachine.WhenthesystemisON,theVPMcontrollerwillmonitorthepower
voltage.If
thevoltageislowerthantheprogrammablethreshold(LOW_THRESHOLD),the VPMcontrollerwill
starttocountdownadelay(LOW_DELAY).DuringthestageofLOW_DELAYcountdown,ifvoltage
goesbackaboveLOW_THRESHOLD,theVPMcontrollerwillstopcountingdownandexit.
IfLOW_DELAYcountstozero,theVPMcontrollerwilltrigger
anpoweroffevent(i.e.powerbutton
press)andstartstocountdownnextdelayperiod(LOW_HARD_DELAY).IfLOW_HARD_DELAYcounts
tozero,thesystempowerwillbecutoffabruptlytoavoiddrainingthepower.

Youcansetthedelayandharddelaytimeofthelowvoltage
eventandignitionevent.
LowVoltageEvent
 Delay:
ThedelaytimebeforeVPMtriggerapoweroffevent(i.e.powerbuttonpress).
 HardDelay:
Thedelaytimecounteddownafterapoweroffeventistriggered.VPMwillforcepoweroffthe
machineiftheharddelay
timeiscounteddowntozero.
IgnitionEvent
 OnDelay:
ThedelaytimebeforeVPMtriggeranpoweronevent(poweronthemachine).
 OffDelay:
ThedelaytimebeforeVPMtriggeranpoweroffevent(i.e.powerbuttonpress).
 HardOffDelay:
Thedelaytimecountedafter
anpoweroffeventistriggered.VPMwillforcepoweroffthe
machineiftheharddelaytimeiscounteddowntozero.
