TROUBLESHOOTING

 

Follow

 

these

 

simple

 

checks

 

before

 

replacing

 

your

 

rain

 

sensor:

 

System

 

will

 

not

 

come

 

on

 

at

 

all:

 

A.

 

Check

 

to

 

see

 

that

 

the

 

rain

 

sensor

 

discs

 

are

 

dry

 

and

 

switch

 

“clicks”

 

on

 

and

 

off

 

freely

 

by

 

pressing

 

the

 

top

 

of

 

the

 

spindle.

 

B.

 

Look

 

for

 

breaks

 

in

 

the

 

wire

 

leading

 

to

 

the

 

rain

 

sensor

 

and

 

check

 

all

 

wire

 

junctions.

 

C.

 

If

 

the

 

rain

 

sensor

 

is

 

dry

 

and

 

the

 

wire

 

leading

 

to

 

it

 

is

 

good,

 

check

 

the

 

rain

 

sensor

 

switch

 

by

 

nicking

 

the

 

insulation

 

of

 

the

 

two

 

“outer”

 

wires

 

near

 

the

 

unit

 

to

 

expose

 

copper.

 

Turn

 

one

 

sprinkler

 

zone

 

on,

 

and

 

apply

 

a

 

“jumper

 

wire”

 

across

 

the

 

two

 

exposed

 

wires.

 

If

 

the

 

sprinkler

 

now

 

comes

 

on,

 

the

 

switch

 

is

 

bad.

 

Wrap

 

all

 

nicked

 

wires

 

with

 

electrical

 

tape.

 

D.

 

The

 

rain

 

sensor

 

is

 

wired

 

to

 

function

 

with

 

most

 

controllers

 

(

normally

 

closed

).

 

If

 

you

 

are

 

unable

 

to

 

make

 

the

 

sensor

 

work

 

with

 

the

 

suggestion

 

above

 

you

 

may

 

have

 

a

 

unique

 

controller

 

(normally

 

open).

 

System

 

will

 

not

 

shut

 

off

 

even

 

after

 

heavy

 

rainfall:

 

A.

 

Check

 

wiring

 

for

 

correct

 

installation

 

(See

 

“Adjustments

 

and

 

Operation”

 

section).

 

B.

 

Check

 

sensitivity

 

setting

 

on

 

rain

 

sensor,

 

and

 

move

 

the

 

cap

 

to

 

a

 

more

 

sensitive

 

setting.

 

The

 

rain

 

sensor

 

is

 

an

 

accurate

 

rain

 

gauge

 

and

 

can

 

be

 

verified

 

by

 

setting

 

up

 

a

 

“tube”

 

type

 

rain

 

gauge

 

in

 

the

 

same

 

vicinity

 

and

 

making

 

periodic

 

readings.

 

C.

 

Check

 

for

 

obstructions

 

to

 

rainfall

 

such

 

as

 

overhangs,

 

trees

 

or

 

walls.
