PAR+ES

Specifications

The controllers, where indicated and shown on the drawings, shall be Rain Bird PAR+ES controllers; microprocessor-based, solid-state controllers. The PAR+ES controller shall be capable of having 16, 24, 32, 40, 48, 56, 64, or 72 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 seven (7) eight-station Output Station Modules with station switches (OSM-S), giving the availability of 16, 24, 32, 40, 48, 56, 64, and 72 stations. These OSM-Ss 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-controller communication. For any central control operation to occur, the Interface Board must be installed.

The PAR+ES controllers shall be housed in a sturdy, heavy duty, temperature and chemical resistant, injection molded high-impact resistant, plastic pedestal enclosure.

The pedestal enclosure shall be 35” 1/4 tall, 17" wide and 20” 1/2" 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 pedestal enclosure shall available in two (2) colors, grey and green.

All PAR+ES models are UL & C-UL listed, CE approved and C-Tick compliant.

The PAR+ES controller units shall be capable of operating under the following power requirements at 50/60 Hz frequency: 1) 115 VAC Nominal [98-132 VAC], 2) 220 VAC Nominal [208-232 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 sixteen (16) standard Rain Bird solenoids at one time at 60 Hz or twelve (12) standard Rain Bird solenoids at one time at 50 Hz.

The PAR+ES 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+ES models shall be capable accommodating conduit diameters of up to one inch.

Each unit shall have a circuit breaker that can be reset, rated 5.25 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 pedestal 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 OSM-Ss shall be installed in the pedestal base. The OSM-Ss 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 72 stations. The OSM-Ss shall have standard station switches with AUTO, OFF and ON positions. PAR+ES plastic pedestal models shall have up to three 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 OSM-Ss.

The panel assembly of the PAR+ES 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+ES 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+ES controller units shall have six (6) automatic schedules possible and two (2) multi-manual 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 controller in stand-alone mode only, and 4) “MAXI” (central control), to allow for the response of the PAR+ES controller 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 controller 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+ES controller itself. In the MANUAL mode, the PAR+ES controller 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+ES controller shall be capable of multi-station operation, simultaneously operating up to six (6) automatic schedules with a limit of twelve (12) at 50Hz or sixteen (16) at 60 Hz solenoids operating at one time. Multi-station 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) multi-manual programs.

Under all normal central control operation, all station timing (for the 16-72 individual stations) of the PAR+ES controller 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+ES unit itself. A PAR+ES controller with more than 24 stations shall be assigned to two (2) (25 to 48 stations) or three (3) (49 to 72 stations) different central control channels. The programming on the PAR+ES unit itself shall be functional only in case of an emergency, should the communication link between the controller 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 controller unit to the backup or the central mode of operation.

The PAR+ES controller, 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 controller 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 controller 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+ES controllers, 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 controller 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+ES 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+ES keypad and panel display.

All PAR+ES controller, 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+ES controllers shall be as shown on the drawings or as instructed and shall be as manufactured and furnished by

Rain Bird Corporation, Glendora, California, U.S.A.
