4.2 Unit operaon modes
L-PAK150/250Advancedhasthefollowingfouroperaonmodes:
1. Omode
2. Standbymode
3. Runningmode
4. Idlingmode
SeeSecon5.1. Status messagesformoreinformaonabouteachmode.
Howtheunitmovesfromoneoperaonmodetoanotherisexplainedbelow.
SeealsoFigure1foraowchartshowinghowtheunitgoesthroughitsfour
dierentoperaonmodes.
WhentheunitisinOmode,theunitcanbeputintoStandbymode(the
unitisready)withitsmotoroandtheFilterCleaningValve(FCV)closedby
pressingtheStandby/Runningbuon.WhiletheunitisinStandbymode,the
unitcanbeputbackintoOmodeagainbypressingtheStandby/Running
buon.
NOTE! Ifpowerislosttotheunit,forexampleifthereisapoweroutage,and
ZerovoltagedeteconissettoOFFseepage16,theunitgoesimmediately
backintoStandbymodeoncepowerisresumedwithouthavingtopushthe
Standby/Runningbuon.
TheunitgoesfromStandbymodeintoRunningmodewhenitreceivesapilot
signalbyavalvebeingopenedatoneormoreworkstaons(inotherwords,
someonestartstowork).Theunit’smotorisnowonandtheFCVisclosed.The
DIR_TimeandSSR_Timemersarenotstarted,seeSecons6.2.4. DIR_Time
and6.2.5. SSR_Time.
TheunitstaysinRunningmodeaslongasthereisanacvepilotsignal.
However,theunitcansllbeputintoOmodebypressingtheStandby/
Runningbuon.
Notethatifonlyoneworkstaonisconnectedtotheunit,orifonlyonework
staonisinuseandworkstopsatthatonestaon,thepilotsignalstops.If
thereismorethanoneworkstaonconnectedtotheunit,andmorethan
oneworkstaonisinuse,thepilotsignalonlystopsifworkstopsatall
workstaons(inotherwords,allvalvesclose).
Whenthepilotsignalstops,theDIRandSSRmersstart.Ifworkresumesat
oneormoreworkstaonswithin10seconds,theunitstaysinRunningmode.
TheDIRandSSRmersareresetbacktozeroandarestopped.
IfDIR_Timeissetfor10seconds(default),andthepauseinworkislonger
than10seconds,DIR_Timeelapses.TheunitthengoesintoIdlingmodewith
itsmotoronandtheFCVopen.
Ifanewpilotsignalissentwithin12minutes,theunitgoesbackintoRunning
mode.TheDIRandSSRmersareagainresettozeroandarestopped.
However,ifSSR_Timeissetfor12minutes,whichisthedefaultseng,and
thereisnonewpilotsignalwithin12minutes,SSR_Timealsoelapses.
TheunitthengoesintoStandbymodeunliteitherreceivesanewpilotsignal
thatputstheunitbackintoRunningmode,ortheunitisturnedo(inother
