OPERATION
TheAutoOn/OverridePowerPackcanbeturnedONandOFFautomaticallyusingan
occupancysensorinput,atimer,panelorBASinput,andmanuallyfromanoptionallow
voltagemomentaryswitch.
AUTOON(SeeWiringDiagram):
Theoccupancysensorinput,HoldONinputandtheoptionalmomentaryswitchinputcan
all be used to turn the load ON.
WhentheloadisturnedOFFusingthemomentaryswitch,thepowerpackdoesnotturn
itONautomaticallyuntilafterthesensortimedelayexpires(e.g.,presentationmode).
PressingthemomentaryswitchbeforethesensortimedelayexpiresturnstheloadON.
Whentheoccupancysensor’stimedelayexpires,thepowerpackrevertstoAutoONmode
anditturnstheloadONwiththenextinputfromtheoccupancysensor.
MANUALON(SeeWiringDiagram):
OccupantsmustpressthelowvoltagemomentaryswitchtoturntheloadON.
When the occupancy sensor is the only input keeping the load ON, the load turns OFF
whenthesensortimedelayexpires.Ifthesensorinputre-triggerswithin30secondsafter
