Decoders Menu
ACC2 Decoder controllers have an additional menu for
decoder functions. ACC2 is designed to work with Hunter
ICD decoders, and will not operate decoders from other
manufacturers.
PROGRAM DECODER
This allows setting or changing a decoder’s station
address(es). Hunter decoders must have at least one station
number programmed into the decoders before they will
operate.
In order to program (or re-program) a decoder, it must be
connected to either the Programming Port in the controller
cabinet, or connected to the two-wire path.
Hunter ICD decoders may also be programmed at any time
with the ICD-HP handheld programmer, instead of using these
menu functions.
Select the Programming Port or the 2-Wire Path for the
decoder you wish to program. To use the Programming Port,
insert the decoder’s red and blue wires in the Programming
Port holes (inside controller cabinet). It does not matter which
color wire goes in which hole.
Then press the so key labeled Read Decoder. This will return
the conguration of the decoder in the port, with a screen for
entering the station numbers. If the screen says “Decoder Not
Found!” the decoder wires may be disconnected, or the wrong
wires may have been inserted.
When a decoder is found, the screen will display the details
about the decoder, including serial number, type, station
size, power factor, inrush, and output assignments. A new,
unprogrammed decoder will have blanks for the station
assignments.
SERIAL NUMBER
The serial number identies the decoder, but is not normally
used in ACC2 Decoder operations.
DECODER TYPE
This function detects and shows the decoder type. There are
four sizes of station decoder, plus ICD-SEN sensor decoders.
POWER FACTOR
This adjusts the amount of power the decoder uses to activate
a station. It is normally set to two and should only be changed
when this is inadequate.
INRUSH
This adjusts the inrush timing for solenoids and relays. This is
normally set to ve and should not be changed unless advised
by Hunter technical advisers.
OUTPUTSTATION
Each station output has a color-coded pair of wires, to which a
controller station number can be assigned.
