4. Gate 1 or Gate 2 (Gate 1
and Gate 2 if dual gate)
operating speed has
slowed down
Whenthegateisrunningslow,thereasonislowpower.The
Sentrychargecontrollerdoesnotoutputanyvoltageorcurrent
whendisconnectedfromthebattery,youcannotcheckthe
chargecontrollerbydisconnectingfrombatteryandmeasuring
outputvoltage.Tocheckchargecontrolleroutput,disconnect
frombattery,measurebatteryvoltageandnote.Reconnect
chargerandmonitorbatteryvoltageitshouldriseabovethe
batteryvoltagenotedabove.
Twothingsneedtobeconsidered.
1. Batterycondition(replaceorcharge)
2. the1/4”ringterminalslocatedonthePlugNGoharness
whichareconnectedtothebattery.Theringterminalscan
becomecorrodedandneedreplacingovertime.
Removebatteryandhaveitloadtestedatabatteryshop.
Replaceifbad.
5. Single or Dual gate
installation will not
automatically close
If control switch number 1 is turned “ON” then the gate will
only auto close from the fully open position.
1. Locatethe“Open/CloseCommand“pushbutton;pressthe
buttontoverifythatthegatewillclose.Ifgateclosescorrectly
thenproceedtothestepsbelow.Ifgatewillnotclosegoto
step5.
2. Verifythatcontrolswitchnumber1isturned“ON”.Gatemust
becycledonceswitchisturned“ON”forcontrolboardto
recognizeswitchsetting.
3. Ifyourinstallationisasinglegateverifywhichlinearactuator
connector(Gate1orGate2)oncontrolboardyouareusing.
ThenverifythatthecontrolswitchforthatGateisturned
“ON”andtheotheristurned“OFF”.
4. IfphotoeyeorothersafetyaccessoryisconnectedtoJ2
thenweneedtoverifycorrectoperationoftheaccessory.To
determineifthismightbetheproblemdisconnectthewire
thatisconnectedtoJ2pin5andcyclegatetoseeifproblem
persists.Ifgateautocloses,accessorydisconnectedis
holdinggateopenverifywiringandoperationofdevice.
5. ThereceiverP2relaycouldbesetforlatchopenmode.To
verify:pressthetransmitterbutton2onetime,thenpressthe
transmitterbutton1onetimeandseeifgatecloses.Ifgate
closes,thentheholdopenmodewasenabled.Formore
