Decoder Wiring Procedure - Secondary Path
Connect the two (2) white decoder wires to the
1.
two (2) solenoid coils of the valve-in-head rotor or
remote control valve�
Record the decoder address and following the
2.
instructions in the PAR+ES Operation Manual, add
the decoder address to the appropriate station at
the controller�
Connect the two blue decoder wires to the wire
3.
path from the controller, one to the red wire and
the other to the black wire�
Field Surge Protection for Decoders
LSP-1 surge arrestors are required for surge protection
of decoders and solenoids� The LSP-1 surge arrestors
consist of several surge arrestor devices potted in a
cylindrical yellow plastic case� The LSP-1 has two blue
wires and two green wires�
Install LSP-1s in the following locations:
Install LSP-1s so that there is no more than eight
z
z
decoders between two LSP-1s or so that there is
no more than 500 feet between LSPs, which ever
is less�
Install LSP-1s at the last decoder in a dead end of
z
z
a wire path�
Connect the two blue wires to the primary path
1.
wire, one to the black and one to the red wire�
Connect the green wire that has the closed eye
2.
spade securely to the core tube of the solenoid
on the valve-in-head rotor or to a remote control
valve by using a stainless steel nut threaded onto
the core tube�
Connect the green wire to a ground rod on a
3.
grounding grid using a brass clamp�
NOTE:
!
A resistance of 50 ohms or less is
required for the LSP-1 surge arrestor to be
effective�
If the decoder is not located next to the solenoid,
4.
install the LSP-1 near the decoder and connect
both green wires to the grounding grid using
separate brass clamps�
