Multiple Stations Do Not Water
(Many station lights on)
Station LED for the suspect zone turns on, and other station LEDs turn on.
If a zone does not water but that station's red LED light turns on as well as other
various LEDs for other stations, the field "common" wire for those stations is not
connected (floating) to the controller. Check the field wiring common connection at
the controller and at the field junction where they may be tied together. Check for
continuity of the common line from the controller to the field valve.
The following schematic diagram illustrates a sample wiring configuration of four
solenoids connected to station outputs:
Controller Station Output Board
The solenoids connected to station outputs 1, 4, and 7 share one common line
return to the station output board. Station #9 is shown as a normal operating station,
which is connected independently from the other stations (not sharing the common
connection).
If the common line is broken or open (as shown by the cross marks), current does
not flow and the solenoid is not energized. This condition is possible whenever
groups of field valve wiring configurations are tied together to one common return
line.
In the example above, if station 1, 4 or 7 are activated, the station LEDs for 1,4 and 7
will all illuminate but the solenoids will not energize.
Note: Station 9 LED will not be illuminated and solenoid will not be energized
because station 9 does not share a common with station 1, 4 or 7.
