Overview'
The$ model$ 2WIRE-AS-1,$ 2$ Wire$ Auto$ Start$ gen erator$ con troller$ is$ ready$ to$ use$ with$your$P$and$S$ s eries$ PRAMAC$Portable$
Generators$ t hat$are$f itte d$with$the$C ONN$r emote $c o ntrol$ con nector$plug.$This$will$enable$you$to$use$your$Pramac$Generator$in$

Product'Features'
The$ 2WIRE-AS-1$controller$is$a$ basic$2$wire$auto$ s tart$accessory$that$manages$the$start/stop$of$the$generator$ from$a$closed$
circuit$ open/closed$contact$ from$a$third$party$ control$system$ like$ a$solar$ inverter$ or$ A TS$trans fer$switch.$It$also$ma nages$the$
basic$generator$running$&$protection$to$ensure$easy$operation.$T he$package$is$supplied$with$a$basic$12V$battery$charger$for$
trickle$charging$of$the$generator$battery$during$standby$mode$waiting$for$a$sta rt$signal.$Customers$can$us e$their$own$battery$
charging$system$but$care$must$be$taken$to$not$over$charge$the$battery$voiding$warranty.$The$basic$setup$is$for$a$simple$system$
suited$for$the$PRAMAC$Portab le$S$&$P$series$models$with$the$CONN$connector$remote$plug.$
Installation'
NOTE:$
PRAMAC$ Generators$supplied$
with$the$2WI RE-AS-1$can$start$automa ti cally$at$anyti me .$For$ safe $operation$ we$ad v i se$
the$generator$is$ c lear ly$lab elled$advising$that,$“Generator'may'start'at 'anytime'without'warning”.$Turn$the$ key$off$ prior$to$
refuelling,$ maintenance$ or$ storage.$ Also$ ensure$ that$ the$ generator$ i s$ installed$ in$ a$we l l-ventilated$ area,$ensuring$ exhaust$
gases$are$not$recycled$back$into$the$engine$or$where$f umes$could$cause$harm$to$people$or$ani mals.$
$
The$ 2WIRE-AS-1$ comes$ pre-wired,$ makin g $ it$ ready$ to$ plug$ into$ y our$ PRAMAC $ Generator.$ The$ control$ plug$ will$ connect$
directly$ into$ the$ Pramac$ CON N$ Remote$ Control$ co nnector $ plug$ on $ the$ P$ &$ S$ series$ Portable$ Generators.$ It$ also$ comes$
standard$with$a$3$pin$plug$top$that$is$plugged$into$your$generator$ output$ s ocket$or$har dw ired$in to$the$generator,$giving$the$
controller$the$required$generator$voltage$feedback$(NOTE;$must$be$installed$ for$controller$to$o perate$c o rrectly).$If$the $23 0$
volt$ feedback$wire $is$required$to$be$hard$w ired,$jus t$cut$the $plug$off$and$h ard$wire$it$to$a$suitably$ protected$generator$output$
circuit.$The$2WIRE-AS-1$can$also$start$the$ generator$off$ a$ 12$volt$DC$ signal,$you$ just$have$to$move$the$flex$into$the$Auto$12v$
terminals$inside$the$con troller$enclosure.$Due$to$there$being$a$small$load$on$the$battery$when$the$controller$is$in $ Auto$mode,$
a$b attery$charger$is$also$provided$to$keep$ your$battery$in$a$fully$char ged$ state.$Just$plug$ your$ ‘plug$pack’$style$charger$ into$
the$provided $s ocket$on$the$base$of$the $controller.$You$can$al so$use$a$suitable$small$solar$pa nel$regulated$changer$plugged$
into$the$same$socket.$

Operation'
To$ operate$your$2WI RE -AS-1$controller,$simply$connect$as$above$and$turn$ the$generator$key$to$the$‘ON’$position.$T he$LCD$
screen$on$the$ controller$will$power$up,$allowing$you$to$either$manual$start/s top$the$generator$or$activate$AUTO$ mode.$To$
manual ly$start$the$gene rator $you$can $either $use$the$key$on$the$set,$or$simply$press$the$green$ start$bu tto n.$This$will$initiate$the$
start$sequence$of$the$controller,$with$a$small$delay$before$the$ generator$ starts$to$ turn$ over.$If$there$are$any$problems,$and$
the$generato r$fails$to$start,$an$error$code$will$appear$on$the$LCD$panel.$Your$generato r$ha s$been$pre-delivery$tested,$but$if$
you$ have$any$ pr oblems,$i t$is$r ecommended$to$d o$th e $initia l $start$up$ using$ the$key$start.$T o$stop$ the$generator,$press$ the$red$
Stop$butt o n .$This$will$initiate$the$stop $sequence,$but$the$gen e rator$will$not $shut $do wn$strai ght$aw a y $d ue $to$30 $second$cool$

To$set$the$contro ller$to$start$from$the$2$wire$or$12$vo lt$signal$automatically,$simply$press$the$middle$AUTO$button.$The$LED$
indicator$above$the$AUTO$button$will$illuminate$showing$you$that$it$is$in$AUTO$mode.$As$noted$abov e,$please$ make$sure$ that$
you$have$a$12$volt$battery$charger$source$plugged$i n$to$of fset$the$small$load$on$the$battery$while$in$Auto$mode.$On ce$the$
controller$has$ received$the$start$signal$there$is$a$short$ delay$while$the$controller$goes$through$its$start$sequence.$O nce$the$
controller$reads$a$voltage$from$the$alternator/generator,$it$will$complete$the$start$cycle$and$keep$the$generator$running$until$
the$stop$sig n al$is$re cei ved.$Onc e $the$2$wire$o r$12$ v ol t$run$signal$ i s$removed$th e$generator$will$ g o $i n to$the$stop$mode ,$with$a$
