5. The display will show "DECODER FUNCTIONS," at the
bottom of the selections. Use the down arrow button to
select Decoder Functions. Press the + button to select.
6. The Decoder Functions screen will appear, with
"Program a Decoder" highlighted.
(The other functions are explained in detail in the Special
Decoders Section). Press + to select. The display will
then show "Checking for a decoder..." as it attempts
to communicate with the decoder in the Programming
Port. The Communicating LED on the output module
will light amber when the programming port is in use
(communicating with a decoder.)
7. The decoder output module will check for the presence
of a decoder. If the wires are correctly inserted into
the Programming Port, a screen will appear with the
decoder settings.
8. If a decoder is recognized, the display will show
current settings for the decoder. If the decoder
is recognized as a station decoder, the size of the
decoder (1, 2, 4 or 6) will show in the DEC TYPE area.
Decoder type can be Station or Pump. Most decoders
in most systems are type "Station", which activate
irrigation solenoids.
• Use the up and down arrow buttons to highlight
different settings, and the + and – buttons to change
them.
• Station number (When Dec Type is "Station") can be
any number from 001 to 099. Do not allow more than
one decoder in a system to have the same station
number!
• Power Factor is normally 2 and this is correct for
most installations. Possible range is 1 to 5. In certain
situations it may be necessary to change this value
to hold in heavier solenoid loads. These values
will change the duty cycle of the power supplied to
the decoder from 10 to 38% in approximately 7%
increments. this value should not be adjusted unless
absolutely necessary as it may adversely affect the
performance of the rest of the system.
• Inrush is normally set to 3 and this is correct for most
installations. Possible range is 1 to 9. These values
will change the timing of the initial powering of the
solenoid from 0 to 90 mS in 10 mS increments to aid
in activating solenoids and relays with higher inrush
current requirements.

9. When the decoder settings are correct, push the
Program button to send them to the decoder. The
display will show "Programming..." for a few seconds
until the information is downloaded into the decoder.
10. If the programming (of the decoder) is successful,
the display will show "PROGRAMMING COMPLETE"
and prompt for another decoder. Using a ball point
pen, write the station numbers for each output
of the decoder on the aluminum label for later
reference. If the decoder has been accidentally
disconnected or malfunctions, the display will show
"Programming Failed!" This means the decoder was
not programmed (check connection, and try again).
11. When all decoders and stations have been
programmed, turn the dial to Run or any other
position to continue working with the controller.
