our home, now just over 2 yrs old, has rainbird ESP-6TM indoor
controller and (four) irritrol 205T solenoid valves. the system is,
starting a day or 2 ago, completely non-functional. the fuse (in the
controller) is good, as is the 'standby battery, and the 'display' on
controller appears fine (aka normal) in ALL respects and in _all_
functions. it even 'counts down' time remining per zone in the 2
minute test mode and in 'normal automatic' mode, too. however, NONE of
the solenoid valves are allowing water to 'pass' (our house water in
'on', of course), making me think there's some problem with the
'common' from the solenoids to the controller, either where the four
are spliced together before going indoors to the controller, or
elsewhere. even reprogrammed it, tried 'manual start' and 'test' etc,
but no luck - we get ZERO flow.
I could confirm a possible 'fault in the common' circuit _if_
what color wire the irritrol 205 valves use for their 'common'.
I'd just run another 'temporary' wire common wire from one valve to
the controller and retest functionality-if it then worked, the suspect
fault in the 'common' circuit would be confirmed. simpler than digging
up four valves and all the wires inbetween...
is there an 'industry standard' for solenoid valve wire colors, maybe?
I assume one is common, another 'signal' or 'latching', and the third
ground. are they labeled on the valves themselves?(our valves are
half-buried, down inside a 5 or 6 inch diameter PVC tubes/kinda dirty
& dark down there). I'm only concerned, right now, of course, with the
wire colors that are an integral 'part of' the factory-made solenoids
with the colors the 'flunky' sprinkler guy installed
ps-the irritrol website is useless for this info: no wiring specifics
given in their entire site for this valve or _any_
others, no wire
colors mentioned, nor is there an ' install guide'. sheesh.
thanks for your help,
