General Description

Eatons Cutler-Hammer Pow-R-

Command 2000 is a microprocessor-based

programmable lighting controlsystem with an embedded webserverfor robust control. The PRC2000 can be

used as a stand-alone

panelboard ornetworked as a system

. An upgrade canbe purchased to integrate the unit withinBACnet native control networks.

Pow-R-Command 2000 Panelboards

Pow-R-Command 2000 Panelboardsare offered from 100 through 225amperes in main lug and main breakerconfigurations. Available voltagesare 120/240, 208Y/120 and 480Y/277,single-phase and 3-phase. Thepanelboard utilizes both branchmounted standard breakers through100 amperes, and controllablethermal-magnetic breakers which

are controlled by the Pow-R-Command2000 System Controller. The Pow-R-Command 2000 controllers providethe ability to directly operate up to eightbreaker control buses. Such a capabilityallows a single controller to directlyoperate up to 168 GHQRSP and BABRSPcontrollable circuit breakers, withindividual control and status feedbackof each controllable breaker.

The System Controller also includesload override, holiday scheduling,

one-shot or event schedules, off warning

to tenants by blinking lights, memoryloss protection, power failure/brown-out protection, hardware diagnostics,

a real-time clock and 16 dry contactswitch inputs.

Equipment within the Pow-R-Command2000 System may be networked. Up to120 panelboards may be networkedover a shielded twisted pair networkcable without the need for a personalcomputer in the system.

The Pow-R-Command 2000 Panelboardis listed UL

67 for panelboards andUL 916 for energy managementequipment.

BACnet Protocol

The PRC2000 unit can be upgraded

to the B series for integration withinBACnet native control networks.BACnet is a communications protocolwidely used in building automationand controls and adds even moreflexibility to the control system.

Operational DescriptionSheet 0910

Pow-R-Command 2000

PRC2000 LCD Display

System DescriptionCoupled with an embedded web-server, the PRC2000 system containsnetworkable intelligence and providesautomated switching of branch circuitbreakers.

Embedded Webserver

The Pow-R-Command 2000 systemcontains an embedded webserver and

configurable IP address which allowsfor complete programming andcontrol over a buildings IT network.Access is protected by username andpassword features.

BACnet Protocol

If the PRC2000 has been upgraded tothe B series, then it is also capableof communicating across and beingintegrated into BACnet native networks.BACnet is an industry standard com-munications protocol for buildingautomation and controls.

Distributed Intelligence

The system is distributed intelligentand operates as a stand-alone devicethat can control its own circuits. A per-sonal computer is not required for thesystem to operate.

Main Network

The Pow-R-Command System is capa-ble of globally communicating overthe main RS-485 network with up to120 controllers over an end-to-enddistance of 4,000 feet (1,219 m) using ashielded twisted pair network cable. Itis also possible to place all controllersor clusters of controllers onto thefacilitys Ethernet network.

LCD Display and KeypadThe PRC2000 LCD display and keypadprovides local programming, overrideand diagnostic functions.

Memory Loss Protection

Time schedules, time-of-day clock, day/date, and system configuration param-eters are protected from memory loss ifthere is a power failure. The memoryloss protection is rated for 10 years.

Power Failure/Brownout Recovery

When system input power drops belownormal, the system will not lose itsprogrammed information. Upon returnof normal power, breaker positionsscheduled during the power failure

period are immediately updated.No operator interaction is required.

Astronomical Real-Time Clock

Time-of-day, day/date, automatic leapyear and daylight savings time adjust-ments are provided as standard.

Control Software

It is possible to program the panel-board directly through its local RS-485maintenance port with a hand-heldprogrammer or with the lightingmanagement software over a shieldedtwisted pair cable by way of a centraloperators station.

Time SchedulingPow-R-Command 2000 supports 75schedules as local control functions.Any of the 75 local time schedules ina controller can be designated as aback-up schedule to execute only if themaster schedules fail or cease execution.

Holiday Scheduling

Pow-R-Command 2000 supports 16system holidays through the NetworkAccess Device and, additionally, eachcontroller can execute 30 local holidaydefinitions.

Input to Output Switch Matrix

The input to output switch matrixfeature allows any breaker connectedto any panel to be controlled by anyswitch or any group of switchesconnected to any panel on the samenetwork.

Messages/Alarms

The system will maintain an alarm log.The log will record where the alarmoccurred, alarm reason, date and timeof the alarm. The log is maintained innon-volatile memory. The alarm logcan store up to 300 alarms.

Daylighting Optimization

Daylighting optimization is availableusing a combination of inputs on thePRC2000 controller or a Switch Over-ride Controller and dimming cable.

Application Specific ControllersOptional Application Specific Controllersexpand the PRC2000 System throughthe network to customize the systemto meet the needs of the tenant.

Switch Override Controller (SOC)

Switch Override Controller (SOC)

Provides the ability to connect andmonitor up to 48 additional 2-wire drycontact closures from wall switches,occupancy sensors, photocells, build-ing automation system relay contacts

or any remotely mounted device witha dry contact.

Input connections to the controller areself-powered.

It is possible to program any input tothe switch override controller to con-trol any breaker or group of breakersin the system.

Inputs are capable of being individu-ally time-schedule enabled fordifferent days of the week.

Telephone Override Controller (TOC)

Provides a voice prompted methodfor ON/OFF override control of light-ing. It is possible to override an indi-

vidual breaker or group of breakersON or OFF during scheduled ornonscheduled hours using anytouch-tone analog telephone.

The Telephone Override Controllerallows voice prompted control oflighting circuits for up to 1,000 indi-vidual users. It is possible to programany of the 1,000 users to control anybreaker or group of breakers in thepanelboard or system.

System Configurations

PRC Network Architecture

Containing an embedded webserver,each Pow-R-Command 2000 system isprogrammed with a unique IP address

for communication via any standardInternet browser. Web access is stan-dard with the PRC2000. Each controllercan support up to three additionalexpansion panels and can be connectedto a BACnet Client Workstation with anadditional upgrade.

Breaker Control Busses

Every Pow-R-Command ExpansionPanelboard can be configured with theleft and/or right breaker control bussesinstalled. This feature not only permitsstandard and remote controllablebreakers to be intermixed within thesame panelboard, but also permits forgreater flexibility and versatility indesign and control when integratingwith the Pow-R-Command SystemController.
