PAR+ Specifications
The controllers, where indicated and shown on the drawings,
shall be Rain Bird PAR+ controllers; microprocessor-based,
solid-state controllers. The PAR+ controller shall be capable
of having 16, 24, 32, 40 or 48 stations, and operating as
a stand-alone controller or as a satellite controller operated
under Rain Bird central control. The base controller shall
be a 16-station, stand-alone controller. It shall have the
capability of adding up to four (4) eight-station Output Station
Modules (OSM or OSM-S), giving the availability of 16, 24,
32, 40 and 48 stations. These OSMs can be easily added in
the field. It shall have the capability of adding a central
control Interface Board, which will allow operation under
Rain Bird central control for either the standard Rain Bird
two-wire communication path or using the wireless Link radio
for central-to-satellite communication. For any central control
operation to occur, the Interface Board must be installed.
The controllers, where designated as PAR+ PP models, shall
be housed in a sturdy, heavy duty, temperature and chemical
resistant, double-walled ascorene high-impact resistant, plastic
pedestal enclosure. The controllers, where designated as PAR+
SS models, shall be housed in a 304 series, brushed-finish,
stainless steel pedestal enclosure. The stainless steel shall
be 50mm thick and of all welded construction.
The pedestal enclosure shall be 30" tall and 12.25"
wide by 12.06" deep or 16" wide and 36" tall
by 18.5" deep. The enclosure shall be complete with mounting
template and hardware for bolting to a poured concrete base.
The top cover shall have a key operated lock. The plastic
enclosure shall have a front and a back removable panel for
convenient access to both compartments of the pedestal for
installation. The front of the stainless steel enclosure shall
have a removable panel for easy access to the entire pedestal
for installation.
All PAR+ models are UL & C-UL listed, CE approved and
C-Tick compliant.
The PAR+ controller units shall be capable of operating under
the following power requirements at 50/60 Hz frequency: 1)
115 VAC Nominal [95-132 VAC], 2) 220 VAC Nominal [205-232
VAC] and 3) 240 VAC Nominal [225-255 VAC]. The transformer
shall be capable of stepping down 115/220/240 VAC input power
to 26.5 VAC output power for the operation of solenoid remote
control valves and/or valve-in-head sprinklers. The transformer
shall be rated at 5.25 AMP capacity for operating a maximum
of twelve (12) standard Rain Bird solenoids at one time at
60 Hz or ten (10) standard Rain Bird solenoids at one time
at 50 Hz.
The PAR+ transformer connector shall have two "pigtails"
preinstalled into the power connector to facilitate wiring
to primary power. For 120 VAC operation, one shall be plugged
into the common terminal and the other into the neutral terminal.
For 220/240 VAC operation, these same positions correspond
to the two hot terminals. The mounting bracket in all PAR+
models shall be capable accommodating conduit diameters of
up to one inch.
Each unit shall have a circuit breaker that can be reset,
rated at 4 AMPS. All controllers must be grounded to 10 OHM
or less. The unit shall use relays and metal oxide varistor
(MOV) surge arrestors to electrically isolate the circuitry
from field noise, while providing a physical gap to protect
against surge damage from coming in on the field wiring. The
panel which houses the Main Logic Board shall have a detachable
harness that connects to the Power Interconnect Board in the
pedesta base, allowing for quick removal of the panel assembly.
The controller shall use socketed EPROM chips on the printed
circuit boards to allow easy upgrade of the controller software.
The OSMs shall be installed in the pedestal base. The OSMs
shall have harnesses that daisy chain the OSMs together in
the pedestal base and allow for easy field upgrades to increase
total capacity up to 48 stations. PAR+ plastic pedestal models
shall have two 24 station terminal boards available to facilitate
field wire installation. Each board in turn shall have its
own preinstalled 18-gauge wire harness, with the other ends
of the harnesses prewired in groups of eight into connectors
for quick and simple connection to the OSMs. In PAR+ steel
pedestal models, the field wires shall attach to the OSMs
with quick disconnect connectors, facilitating installation
and reducing the need to disconnect and reconnect field wires.
The panel assembly of the PAR+ controller shall have a sealed
and sloped keypad and display to keep moisture and contaminants
away from the critical electronic components of the unit.
A clear, 32-character (two [2] lines of 16 characters each)
alphanumeric crystal display shall be used to show the operational
information and diagnostic data of the controller in an easy
to read manner. Indicating LEDs shall give a visual indication
of the active schedules and the central control status. The
control panel shall have 20 large, raised buttons with clear,
descriptive icons and English labeling to facilitate local
programming.
The PAR+ controller shall have eight (8) user-selected languages:
English, French, German, Italian, Japanese, Portuguese, Spanish
and Dutch. A language display shall act as a prompt.
The PAR+ controller units shall have six (6) automatic schedules
possible and two (2) multimanual programs available. Each
of the independent schedules shall have the capability of
up to twelve (12) start times per day and overlapped starts
shall automatically "stack." Water budgeting for
each independent schedule shall be able to be selected from
0 to 200%, in 10% increments to allow automatic changes to
all station operating times of stations within the schedule,
without separately reprogramming each station. Each individual
station shall allow for the setting of operation times from
one (1) minute minimum time to one hundred twenty (120) minutes
maximum time, in one (1) minute increments.
The CONTROL mode shall provide for four (4) controller control
modes: 1) "OFF," for "Rain Shut-Down,"
2) "MANUAL," for manual starts only to operate,
3) "LOCAL," to operate the satellite as a stand-alone
controller only, and 4) "MAXI" (central control),
to allow for the response of the PAR+ satellite unit to the
Rain Bird central computer program (this light will only be
active if the central control Interface Board is installed).
Under central control, the satellite shall ignore any of its
own individual programming unless a loss of control commands
from the central is detected. Under LOCAL operation, the controller
must be programmed for its desired operation, at the PAR+
controller itself. In the MANUAL mode, the PAR+ satellite
shall be capable of manual operation only, with no LOCAL or
Maxi (central control) scheduling capable of operating. Under
the "Rain Shut-Down" condition, clock irrigation
activity will not start.
The PAR+ controller shall be capable of multistation operation,
simultaneously operating up to six (6) automatic schedules
with a limit of ten (10) at 50Hz or twelve (12) at 60 Hz solenoids
operating at one time. Multistation programming shall be accomplished
by having the capability to assign any station to one of six
(6) different schedules. It shall have the capability to operate
one station from each of these six (6) schedules simultaneously.
All stations within a given schedule shall line up and operate
in sequence one after the other. Any given station may be
assigned to more than one schedule. It shall be capable of
operating two (2) multimanual programs.
Under all normal central control operation, all station timing
(for the 16-48 individual stations) of the PAR+ satellite
unit shall be done from the central control unit and NOT according
to the times that may be programmed for each of its stations
at the PAR+ unit itself. A PAR+ satellite with more than 24
stations shall be assigned to two (2) different central control
channels. The programming on the PAR+ unit itself shall be
functional only in case of an emergency, should the communication
link between the satellite and the central be lost. The change
over to the "Stand-By" program and/or back to Maxi
(central control) status shall take place automatically and
will not require a trip to the field to set each satellite
unit to the backup or the central mode of operation.
The PAR+ satellite unit, when operated by the central control,
shall be capable of RANDOM ACCESS or operation of the individual
stations and is not required to be operated in numerical sequence.
Any of the stations may be repeated anywhere within the schedule’s
cycle of operation, as often as desired and for a different
amount of time on each repeat. It also shall be possible to
place any individual station of a satellite in as many different
scheduled cycles as may be desired. There will be no limit
or restriction as to the number of individual scheduled cycles
a given satellite station may be scheduled in at any time.
The built-in, back-up program and nonvolatile memory shall
maintain schedules and time of day during a power outage for
up to 10 years.
TWO-WIRE COMMUNICATION: If so specified, a two-wire communication
path shall be used to communicate between Rain Bird central
control equipment and the PAR+ satellites, provided that the
central control two-wire Interface Board is installed in the
unit. This two-wire path shall also be used to communicate
back to the central equipment. This feedback signal shall
be used by the central to verify and log all satellite activity.
TWO-WAY WIRELESS COMMUNICATION: The wireless Link central
control option shall use a UHF transceiver with a Rain Bird
modem in place of the standard two-wire interface. The central
control two-wire interface board shall be replaced with a
special Link interface board designed for PAR+ application
and installed in the same location. An additional transformer
supplies power for the Link radio.
The central control interface type, along with firmware version
numbers installed for both the controller Main Logic Board
and the central control Interface shall be able to be queried
via the PAR+ keypad and panel display.
All PAR+ satellite, low-voltage station output wiring shall
be type UF single conductor annealed soft copper wire with
a 0.06" thick PVC insulation jacket. Wires are of the
sizes indicated on the drawings and of the colors indicated
or directed. All splices and all underground connections,
for both two-wire communication and the station output wiring,
shall be made using either 3M, DBY or DBR (direct burial)
splice kits or 3500 Scotch-Lok connector packs. All underground
wire joints and connections shall be in standard size rectangular
valve boxes, except at solenoids and OSM connections.
The model, location and number of PAR+ controllers shall
be as shown on the drawings or as instructed and shall be
as manufactured and furnished by
PAR+
