maximum of 125-John Deere Golf
Irrigation style decoders (John Deere
Golf Irrigation part number AD111,
A121, AD122, AD132 or AD142).
The external station and decoder
wiring configuration and the
required decoder operating voltage
shall provide the limitation to the
number of simultaneous stations
and decoders operating.
The field controller shall be capable
of being upgraded in the field to
control decoders, valves, or pumps
via inserting valve modules (John
Deere Golf Irrigation part numbers
ACVLV0, ACVLV1, AC016UGD,
AC116UGD, AC016EXP or AC116EXP,
as appropriate).
The transformer shall be rated at
3.2-amp output capacity for operating
a maximum of 27 standard 2-watt
solenoids plus a master valve
at once. For controller requiring
more than 48 stations, a separate
power supply shall be integrated
into the controller.
The field controller shall be connected
directly to a flow sensor (John Deere
Golf Irrigation part number AC220SS),
without the need for any interface
or transducer.
The field controller shall be capable
of automatic adjustment of all
ET-based schedules with reference
to a locally mounted John Deere
Golf Irrigation approved ET device
(John Deere Golf Irrigation part
number ACETGS).
The field controller shall be capable
of connection to sensor board
(John Deere Golf Irrigation part
number ACANSC) to read John Deere
Golf Irrigation approved industrial
linear sensors capable of transmitting
0/4-20mA signals.
Setup of the sensors shall be done
directly via the field controller’s
front panel and not dependent on
an external device.
The field controller shall be capable
of being fitted with an optional remote
VHF-radio-receiver (John Deere Golf
Irrigation part number ACVRHCI)
to receive operation instructions
transmitted by a VHF hand-held
radio (John Deere Golf Irrigation
part number AC13VHK). Each field
controller shall be capable of receiving
and responding to such commands
without the intervention or requirement
for a central computer.
The field controllers shall require 117
VAC (100 VAC minimum to 129 VAC
maximum) at 60Hz input power or
220/240 VAC (200 VAC minimum to
260 VAC maximum) at 50Hz input
power. Each unit shall have a step
down transformer for 117 VAC input
power to approximately 33.5 VAC
output power or 220/240 VAC input
power to 33.5 VAC output power
for the operation of solenoid remote
control valves and/or valve-in-
head sprinklers.
The PDPE-style field controller shall
have a durable, heavy-duty plastic
pedestal cabinet with front and rear
splash-proof sealed doors, lid with
key-operated lock and shall be
suitable for concrete pad mounting
(concrete pad provided by others) or
John Deere Golf Irrigation Quick-Pad
mounting (John Deere Golf Irrigation
part number ACPDPEQP).
The field controller shall be capable
of being operated in standalone
mode, or central satellite mode
with the addition of the Aurora
Central Software desktop package
(John Deere Golf Irrigation part
numbers, ASW/PROF) or network
mode with the addition of the
Aurora Network Center (John Deere
Golf Irrigation part number, AIU).
The field controller shall be program-
mable in the field to insert all
manufacturers’ updates without
the need to remove any integrated
modules.
The field controller shall be operated
in local standalone mode, network
or central control mode and will be
able to perform any satellite-specific
manual and/or automatic functions
in all modes. These modes shall be
automatic to the operator and shall not
rely on operator intervention.
The field controller shall be reasonably
protected against electrical surge at
all incoming and outgoing wiring
connections.
The field controller shall be capable of
being fitted with increased incoming
mains surge suppressor modules on
the incoming mains supply wires
(John Deere Golf Irrigation part
number SPNTI) and increased surge
suppressor modules on the control
wires (John Deere Golf Irrigation part
number TWSPK).
The field controller shall have 8,
16, 24, 32, 40, and 48 through 96
stations, in 8-station increments,
with each station capable of an
operating time of 00:00:05 to
23:59:59, in 1-second increments.
Controller station operation shall
be of automatic sequential stacking
to avoid overlapping operation,
unless programmed to overlap.
The field controller shall be protected
against severe electrical surge at
all incoming and outgoing wiring
connections.
Programs will run on an ODD/EVEN
day cycle, day of the week/month
ON/OFF cycle, or in cycles from 1-365
days. In addition, the controller shall
have a programmable rain shutdown
from 1-99 days.
The field controller shall be capable
of being operated fully, manually
or semi-automatically at any time
via an interface unit, remote field
controller/satellite or remote devices
such as VHF-style handheld radios,
mobile phones, laptop computer
or Tablet PCs.
The field controller shall have
John Deere Golf Irrigation “Two-
Way” communication technology
and shall be capable or responding
to instructions sent from a remotely
located John Deere Golf Irrigation
Interface Unit (John Deere Golf
Irrigation Part number AIU) in Network
mode on the same communications
network, without the need for a
central computer and John Deere
Golf Irrigation central software.
The field controller shall be equipped
to support an optional 2-watt
digital network radio and modem
directly, without the need for any
communication module.
Each field controller shall be capable
of utilizing standard telephone,
point-to-point radio (450 470 MHz
[UHF]; 150-170 MHz [VHF]), spread-
spectrum radio (902-960 MHz [USA];
2.4000-2.4835 GHz [INT]), or a directly
connected serial cable as a commu-
nication link to the central computer
or remote handheld device.
If fitted with radio, the field controllers
shall also have a domed hood antenna
mounted on the enclosure or integrated
into the pedestal cabinet and the
antenna coaxial cable connected
directly to the radio unit.
The field controller shall operate on
a multiple communication platform.
Each field controller shall be factory-
set to accept hybrid communication
configurations.
The central software shall download
new or updated control data to all
field controllers for operation as
programmed from the central,
and the field controller shall operate
as programmed.
The field controllers shall operate as
programmed for the calendar period
defined, without any intervention
from the central system.
The field controller shall be equipped
with John Deere Golf Irrigation
Smart-Switch
™ technology to
facilitate control of manual operation
of station outputs without the need
to adjust programs or the usage of
mechanical switches.
The field controller can be operated
in any mode, including random
operation of any individual stations,
and shall not be required to operate
in numerical sequence.
All communication cable supplied
and installed shall be in accordance
with JOHN DEERE GOLF IRRIGATION
CABLING/WIRING SPECIFICATION.
All splices in the station output wir-
ing and all underground connections
shall be made using approved direct
burial splice kits and shall be in

SPECIFICATION.
All underground wire joints and
connections shall be in the standard
size valve boxes, except at valve-in-
head-sprinklers.
Line conditioners shall be installed
at the field controller power source
and shall be the filtered output type.
Line conditioners shall be for 120
Volt, single-phase power rated for
100 Amps or 240 Volt, single-phase
power rated for 100 Amps. It shall
have a discharge capacity of 10,000
Amps at an 8 x 20 second pulse. The
120-Volt devices shall have a clamping
voltage of 130 Volts and a response
time of 1.5 N/sec and the 240-Volt
devices, shall have a clamping voltage
of 250 Volts and a response time of
1.5 N/sec. Surge arrestor shall be
CSA and UL approved.
At the time of installation, each field
controller shall be fitted with a mains
surge suppressor (John Deere Golf
