1 Overview of the Multi-Flex Product LineThe MultiFlex line of control system boardsprovide a wide variety of input, output, andsmart control solutions, all of which are based ona single universal hardware platform. The boarddesign uses flash-uploadable firmware and pluginexpansion boards to configure the base platformboard and apply it for use as an inputboard, relay output board, analog output board,or a combination I/O board.1.1. MultiFlex 16 Input BoardThe board also provides both +5VDC and+12VDC output voltage points for use in poweringtransducers or other input devices thatrequire power.Unlike the 16AI, the MultiFlex 16 has ahand-held terminal interface, which may be usedby technicians to view the input voltage andengineering unit values for each input pointwithout need of a voltmeter or front panel controllerdisplay.Table 1-1 shows the part number of the MultiFlex16.P/N Model Name Description810-3013 MultiFlex 16 16 analog/digital inputs,no outputsTable 1-1 - MultiFlex 16 and 8 Input Board ModelsFigure 1-1 - MultiFlex 16 Input BoardThe MultiFlex 16 input board offers sixteencombination analog/digital input points for useby CPC Einstein and REFLECS control systems.The MultiFlex 16 is designed to be 100% compatiblewith the previous generation of CPCinput boards (the 16AI), and may be used in retrofitswith no additional hardware or softwaresetup or upgrades.Like the 16AI, the MultiFlex 16 communicateswith the site controller via an RS485 connectionto a REFLECS COM A&D network oran Einstein I/O network. Dip switches on theboard set the network ID (board number) andbaud rate.MultiFlex 16 Input Board Overview of the MultiFlex Product Line • 1

1.2. MultiFlex CombinationInput/Output BoardsFigure 1-2 - MultiFlex 168AO Combination Input/Output BoardFigure 1-3 - MultiFlex 1616 Combination Input/Output BoardThere are several models of the MultiFlexboard that combine the functionalities of inputboards, relay output boards, digital outputboards, and analog output boards. The MultiFlexcombination input/output boards are designed tobe replacements for the 8IO Combination Input/Output Board, but the MultiFlex board providesseveral new hardware options and software features.The MultiFlex combination I/O boards consistof two circuit boards: a bottom layer with upto 16 combination digital/analog inputs, and aplug-in top layer which contains different combinationsof relay outputs, digital outputs, andanalog outputs.All boards feature both +5VDC and+12VDC output voltage points for use in poweringtransducers or other input devices thatrequire power.On the RS485 Network, the MultiFlex combinationinput/output boards present themselvesto the Einstein or REFLECS site controller as16AI Analog Input Boards, 8RO Relay OutputBoards, 8DO Digital Output Boards, and/or4AO Analog Output Boards, depending on whattype of inputs or outputs are equipped. DIPswitches are used to assign network ID numbersto each board type.The MultiFlex combination input/outputboards also support a hand-held terminal interface,which allows technicians to view input values,check output states, and override outputpoints with fixed digital or analog values.Table 1-2 shows the available models ofMultiFlex combination input/output boards.P/N Model Name Description810-3063 MultiFlex 88AO 8 analog/digital inputs,8 relay outputs,4 analog outputs810-3064 MultiFlex 88 8 analog/digital inputs,8 relay outputs810-3065 MultiFlex 168AO 16 analog/digital inputs,8 relay outputs,4 analog outputsTable 1-2 - MultiFlex Combination Input/Output Board Models2 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

Other Boards in the MultiFlexFamilyIn addition to the I/O boards describedabove, the MultiFlex hardware is used as thebase for a number of “smart” boards capable ofcontrolling refrigeration and HVAC systems orsubsystems independently from a central sitecontroller. These boards are considered “controllers”in their own right, and are therefore coveredin separate manuals. For informationalpurposes, these boards are described below.1.3.1. The MultiFlex RTU16 analog/digital inputs,16 low-voltage(24VAC rated) relayoutputs, and 4 analogoutputs.16 analog/digital inputs,16 low-voltage(24VAC rated) relayoutputs, and 4 pulsewidthmodulatingdigital outputs.810-3072 MultiFlex 1616L 16 analog/digital inputs,16 low-voltage(24VAC rated) relayoutputs.Table 1-2 - MultiFlex Combination Input/Output Board ModelsSimilar in design to the MultiFlex combinationinput/output boards, the MultiFlex RTUboard is designed specifically for operatingpackage rooftop HVAC units as part of an EinsteinBX or REFLECS BCU building controlsystem. The MultiFlex RTU is designed to be areplacement for the previous generation ARTC,and is 100% compatible with all legacy EinsteinBX and BCU systems.The MultiFlex RTU board has 16 analoginputs, 8 relay outputs and 4 analog outputs.Most of these I/O points are reserved for sensorsand input devices required to read environmentaldata (such as space and supply air temperature)and control all output devices that control theenvironment (such as heat/cool stages anddampers). The RTU relay outputs are rated forline voltage (240VAC).The RTU board controls the rooftop unitdirectly with its built-in heating, cooling, andhumidity control algorithms. It may operate instand-alone mode, or it may interface with anEinstein BX or BCU to control the store environmentin zones and pass along logging andalarm information.The MultiFlex RTU has its own installationand operation manual, P/N 026-1706.1.3.2. The MultiFlex RCBThe RCB is an improved version of the MultiFlexRTU. The RCB has sixteen fully configurableanalog and digital input points, whereasthe RTU has only eight inputs, two of which areconfigurable. The RCB has four analog outputsfor use in controlling variable speed fans, economizersor modulating heating and/or coolingvalves, whereas the RTU has only two analogoutputs for use only with VS fans and economizers.The RCB also features a more sophisticatedHHT interface and updated algorithms for controllingheating, cooling, dehumidification, andair quality.The MultiFlex RCB has its own installationand operation manual, P/N 026-1707.1.3.3. The MultiFlex CUB-II andCUB-TDThe MultiFlex Condensing Unit Board(CUB) is a “smart” input/output board designedto control single condensing units. The Multi-Flex CUB-II controls all aspects of a condensingunit, including compressor control, and con-Other Boards in the MultiFlex Family Overview of the MultiFlex Product Line • 3

denser fan control. The MultiFlex CUB-TD is ascaled-down version of the CUB-II that controlscondenser fans using a temperature differentialstrategy.The MultiFlex CUB uses the same generalhardware configuration as a MultiFlex 168AO.It is equipped with a processor and extra memoryto allow it to control compressors, condensers,refrigeration, and defrost for a singlecondensing unit using on-board I/O and controlalgorithms.The MultiFlex CUB has its own installationand operation manual, P/N 026-1705.1.3.4. The MultiFlex PAKThe PAK is a distributed pack (rack) controllerthat controls compressors and condenserfans. The PAK can control up to 8 compressorgroups containing up to 16 compressors. Thecompressor control strategy is either Fixed Stepswith up to 20 fixed combinations of compressorgroups, or an alternate Cyclic strategy that distributescompressor activations, with setpoint/deadband using ON and OFF delays.The PAK can also control up to 4 condenserfan groups containing up to 8 total condenserfans. The PAK condenser control strategy issequential TD control with setpoint/deadbandusing ON and OFF delays.The MultiFlex PAK has its own installationand operation manual, P/N 026-1712.4 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

2 Mounting and PoweringThe MultiFlex boards are usually installedby the refrigeration or building equipment manufacturer.Therefore, the installer need onlymake the necessary connections between theboards and the site controller(s).In some instances, an installer may berequired to mount an I/O board. There are norestrictions on the location of these boards; however,for ease of network configuration, it is recommendedthat the boards be located adjacent tothe site controller. I/O boards may be mountedwithout an enclosure, but they should bemounted in a location that is not easily accessibleto avoid tampering or damage.2.1. Snap-Track InstallationMultiFlex boards not supplied in a custompanel or other enclosure are supplied with asnap-track for easy installation. The insulationsheet and I/O board must be removed from thetrack before the track is mounted. The snap-trackis mounted using the 0.1875” mounting slots.Figure 2-1 shows this installation procedure.Figure 2-1 - MultiFlex Snap-Track MountingFigure 2-2 provides mounting dimensionsfor all models of the MultiFlex board.Figure 2-2 - MultiFlex Board DimensionsSnap-Track Installation Mounting and Powering • 5

2.2. The Plug-In OutputBoardThe additional board makes the MultiFlexcombination I/O boards considerably taller thanthe MultiFlex 16 and all previous-generationCPC I/O boards. If you will be mounting theseboards in an enclosure, the board will need atleast 2.5" of clearance between the base boardand the panel door.2.3. Powering the MultiFlexAll models of MultiFlex require a 24VACClass 2 input power source. The MultiFlex 16requires the power source to be center-tapped.All other models do not use the center tap.CPC supplies a wide variety of 24VACtransformers with varying sizes and either withor without center taps. Table 2-1 shows thetransformer sizes and whether they are centertappedor non-center-tapped.Figure 2-3 - Exploded View -- MultiFlex Combination I/O BoardAll MultiFlex boards except the MultiFlex16 have output sub-boards that plug in to the topof the base board. These boards are shipped withthe output board pre-installed on the board usingstand-offs, so no additional hardware setupshould be necessary.Xformer P/N VA Rating Primary Voltage Center Tap?640-0041 50 VA 110 VAC No640-0042 50 VA 220 VAC No640-0056 56 VA Multi-tap (120/208/240 VAC) Yes640-0050 75 VA 110 VAC No640-0045 75 VA 220 VAC No640-0080 80 VA Multi-tap (120/208/240 VAC) YesTable 2-1 - Transformers Compatible with MultiFlex Board6 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

2.3.1. Choosing Transformer SizesIn most site installations, a single transformerwill power multiple devices. Choose atransformer with a VA rating large enough topower all devices that will be attached to it.Table 2-2 gives the VA ratings of the MultiFlexboard products. Refer to your site controller’smanual for VA ratings of the other I/O boardsthat may be powered by one of these transformers.Unit VA VAC Centertapped?MultiFlex 16 6 24 YesMultiFlex 88,88AO, 168,168AO and168DO15 24 NOMultiFlex1616L,1616LAO, and1616LDO20 24 NOTable 2-2 - Device Power Requirements2.3.2. MultiFlex 16 Power WiringThe MultiFlex 16 requires connection to atransformer with a center tap such as the 56VA(640-0056) and 80VA (640-0080) transformerslisted in Table 2-1. The 56VA and 80VA transformershave quick-connects on the primary andsecondary sides for connection to line voltageand the MultiFlex 16 board. Figure 2-4 showshow to make those connections. Note the centertap connection on the secondary side (CT) mustbe wired to the 0V terminal on the MultiFlex 16.Figure 2-4 - 640-0056 and 640-0080 Transformer Wiring2.3.3. MultiFlex Combination Input/Output Board Power WiringAll MultiFlex models that use an outputboard layer require a non-center tapped powerconnection. The 0V terminal on the MultiFlexpower connector should be connected to a separateEarth ground, not to the center tap of thetransformer.Important! The rules that must be followedwhen connecting a MultiFlex CombinationI/O board to a transformer aredifferent depending on whether you have a"new style" MultiFlex board with an isolatedpower supply (all MultiFlex boards shippedafter November 1, 2002) or an "old style"MultiFlex board (all MultiFlex boardsshipped before November 1, 2002).Powering the MultiFlex Mounting and Powering • 7

A new-style MultiFlex Combination I/Oboard has a green power LED located next to the24VAC connection terminal in the upper rightcorner of the circuit board (see Figure 2-5 forreference).24 VAC24 VACPOWER LEDNew StyleMultiFlex Board(Top Left Corner)2.3.3.1. New-Style MultiFlex CombinationI/O Boards (with IsolatedPower Supply)The new-style MultiFlex board can be connectedto any of the center-tapped transformersmentioned in Table 2-2, provided the 0V terminalof the board is connected to an Earth ground.A center-tapped transformer may powerboth center-tapped and non-center-tapped boardsat the same time, as long as none of the noncenter-tappedMultiFlex boards are old-styleMultiFlex boards. If an old-style MultiFlexshares the same center-tapped transformer as adevice that uses the center tap, boards on the networkwill be damaged. Figure 2-6 shows how towire a non-center tapped device to a centertappedtransformer.NO POWER LEDOld StyleMultiFlex Board(Top Left Corner)Figure 2-5 - New-Style vs. Old-Style MultiFlex BoardIf there is a power LED next to the connector,your MultiFlex is a new-style MultiFlex --refer to Section 2.3.3.1., New-Style MultiFlexCombination I/O Boards (with Isolated PowerSupply) for power wiring instructions.If there is no power LED next to the connector,your MultiFlex is an old-style MultiFlex --refer to Section 2.3.3.2., Old-Style MultiFlexCombination I/O Boards (No Isolated PowerSupply) for power wiring instructions.Figure 2-6 - Wiring Non-Center Tapped MultiFlex Boards toTransformers With a Center TapIn addition, the MultiFlex combinationboards can be powered by one of the 50VA or75VA non-center-tapped transformers listed inTable 2-1 on page 6. Figure 2-7 shows how towire the transformers to the MultiFlex boards.8 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

You may also tie one side of the secondary(but not BOTH sides) or the center tap to anearth ground, provided none of the boards poweredby the same transformer are old-style MultiFlexboards (see Section 2.3.3.2.).Figure 2-7 - Non-Center-Tapped Transformer WiringAll wire connections to earth ground shouldbe less than six (6) inches long and use a wiregauge of at least 14AWG.2.3.3.2. Old-Style MultiFlex CombinationI/O Boards (No IsolatedPower Supply)Like the new-style MultiFlex board, the oldstyleMultiFlex Combination I/O board can beconnected to any of the center-tapped transformersmentioned in Table 2-2, provided you followthe following three rules:Rule 1: Ground the 0V terminal on the oldstyleMultiFlex board to an Earth ground.Do not connect the center tap of the transformerto the 0V terminal.Rule 2: Do not power an old-style MultiFlexnon-center-tapped board with a transformerthat is also powering a center-tapped device.This means you cannot connect an old-styleMultiFlex non-center tapped board to a transformerthat is powering a MultiFlex 16, 16AI,8RO, 4AO, 8DO, a Gateway board, or any previousgeneration CPC board that uses centertappedpower. Doing so will destroy the Multi-Flex board.Rule 3: The secondary of the transformermust not be grounded on any side.Verify that neither side of the transformersecondary is connected to earth ground beforepowering the old-style MultiFlex board. Agrounded secondary will damage the MultiFlexboard.In addition, the old-style MultiFlex combinationboards can be powered by one of the 50VAor 75VA non-center-tapped transformers listedin Table 2-1 on page 6. Figure 2-7 shows how towire the transformers to the MultiFlex boards.2.3.4. Wire Types and MaximumDistancesFor powering I/O boards, use only the listedwire types from Table 2-3. Three-conductornon-shielded cables are the recommended wirefor connecting between the center tapped transformerand the I/O boards. Shielded cable shouldnot be used for power wiring. The center tapshould be wired with the third conductor to earthground at the transformer.Each MultiFlex board should have its 0V terminaltaken to a short, solid earth ground.Power Wiring Types14 AWG Belden 9495 or equivalent18 AWG Belden 9493 or equivalentTable 2-3 - Power Wiring TypesThe wire length from the transformer and thenumber of boards connected to the same wiredetermines the type wire gauge used.

the transformer that supplies power to them isnot enough to be concerned with. But it is veryimportant not exceed this maximum wire lengthor the boards will malfunction.Use these formulas to determine if the wiregauge you are using fits within specification:14 AWG:Feet = 0.40/(VA/24) x 0.00518 AWG:Feet = 0.40/(VA/24) x 0.013(VA is the total VA rating of the I/O boards)For example, if you had an 80 VA load:14 AWG: 24 ft. (rounded down)18 AWG: 9 ft.Figure 2-8 - Power Wire Lengths10 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

3 The I/O NetworkAll MultiFlex boards and controllers use anRS485 network connection to communicate withEinstein and REFLECS site controllers. Technicianswho are familiar with CPC’s previous generation16AI, 8IO, and ARTC boards will findthe network setup procedure for the MultiFlexboards to be very much the same.3.1. Wire TypesCPC specs Belden #8641 shielded twistedpair cables for use as I/O network wiring (orBelden #82641 and Belden #88641 for plenuminstallations).If the recommended cable is not available inyour area, be sure the wiring meets or exceedsthe following specs:Shielded?Conductor TypeGaugeCapacitance betweensignal wiresCapacitance betweensignal and shieldNominal ImpedanceYesTwisted Pair18 - 24 AWG31 pF/ft or less59 pF/ft or less120Ω±50ΩTable 3-1 - RS485 I/O Network Wiring Specifications3.2. Network Configuration(Daisy Chains)The RS485 Input/Output (I/O) network iswired in a daisy-chain configuration. In a daisychain, boards are wired together in series with nobranches or "star configurations," and the networkis terminated at either end of the daisychain.A diagram of this network arrangement isshown in Figure 3-1.TERMINATIONFigure 3-1 - I/O Network Configurations3.2.1. Maximum # of Boards on aDaisy ChainTo determine how many MultiFlex controllersmay be daisy-chained together, look for aplus sign "+" at the end of the model type on theboard’s plastic insulating cover.Figure 3-2 - MultiFlex "Plus" Board IndicatorTERMINATIONThe "+", which appears on all MultiFlexboards manufactured after May 2004, means theboard is equipped with a low-power networktransmitter. Up to 256 of these boards may beconnected to a single controller. If the board hasno "+" beside the model type, the maximumnumber that can be connected to an E2 is 32.If you have a mixture of plus and non-plusboards, multiply the number of non-plus boardsby 8, and add that to the number of plus boards.This will result in the maximum number ofboards you can interconnect.Wire Types The I/O Network • 11

3.3. Network ID NumbersEach device on an RS485 segment has a networkdip switch that must be used to assign theboard a unique network ID number.The network ID number makes a boardunique from other boards on the network of thesame type. This allows the site controller to findit and communicate with it.Boards of the same type should be numberedin sequence, starting with one and continuingwith two, three, and so forth.3.3.1. Numbering the MultiFlex 16Both the MultiFlex 16 and the previous-generation16AI are recognized as “16AIs” by thesite controller, and therefore each one of bothtypes of boards should have a unique boardnumber.The network ID on the MultiFlex 16 is setusing the first five dip switches on dip switchbank S3. Refer to Figure 3-3 for dip switch settinginstructions.3.3.2. Numbering for MultiFlexCombination I/O Boards.Network numbering for the MultiFlex combinationinput/output boards are a special case.They are actually a combination of four differenttypes of CPC boards. All models have bothinputs and relay outputs, so all models must benumbered as if they were one 16AI and one8RO. In addition, if analog outputs are presenton the board, the analog outputs must be numberedlike a 4AO, and if digital outputs arepresent, the digital outputs must be numberedlike an 8DO.Table 3-2 shows all of the combination MultiFlexI/O boards and the board numbers theyrepresent.MultiFlex 16AI 8RO 4AO 8DOModel Type88 and 168 1 188AO and168AO1 1 1168DO 1 1 11616L 1 2 -1616LAO 1 2 11616LDO 1 2 1Table 3-2 - Model Types and Board Address RequirementsBecause the 1616 family of MultiFlexboards contains the same amount of relays astwo 8RO boards, these boards must be configuredas two 8RO boards with consecutive numbers.Selecting an address on the output switchwill number the relay outputs as an 8RO with theselected address and a second 8RO of the nextconsecutive address (for example, setting theswitch to #1 will number the relays as 8RO #1and #2).Figure 3-3 - 16 Network ID and Baud Rate Switches12 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

Figure 3-4 provides a graphic representationof input and relay output board numbering fortwo MultiFlex 16s, three 8ROs, two MultiFlex88 boards, and a 1616LAO. Note in this configurationthat even though there are only 8 devices,they behave on the network as if they are 13devices: 16AIs #1-5, 8RO #1-7, and 4AO #1.Figure 3-4 - Network Device Numbering (E2 Network Shown)The board numbering dip switches on theMultiFlex 88, 88AO, 168, and 168AO are S3and S4, as shown in Figure 3-5. Switches 1-5 onS3 set the input (16AI) network address.Switches 1-5 on S4 set the relay output (8RO)address, and switches 6-8 on S4 set the analogoutput (4AO) address.3.3.3. Addressing the 168DOSetting up the network ID numbers for the168DO is the same as setting up a 168AO (seeSection 3.3.2.), except switches 6-8 on switchbank S4 set the virtual 8DO board addressinstead of the 4AO address as shown.3.4. Setting the Baud RateAll I/O boards have dip switches that determinethe baud rate at which they communicate.Currently, the baud rate dip switch in networkcomponents may be set at either 9600 or 19200baud. Either may be used -- refer to your sitecontroller’s user manual for the baud rate recommendation(currently 9600 baud for bothREFLECS and Einstein controllers).On all MultiFlex boards, switches 6 and 7 onS3 are used to set the baud rate. To communicateat 9600 baud, set switch #6 UP and #7 DOWN.For 19200 baud, set switch #6 DOWN and #7UP. Refer to Figure 3-3 and Figure 3-5 for avisual look at how the switches must be set.3.5. Setting the TerminatingResistance JumpersAll MultiFlex boards and other RS485devices have a set of terminating resistancejumpers (one jumper for each wire lead). Thesejumpers are labeled JP2, JP3, and JP4 on theMultiFlex board.The purpose of the jumpers is to indicate thetwo ends, or termination points, of the segment.On a daisy chain, one device at the beginningand one device on the end must be terminated.On the MultiFlex, this is done by placing allthree termination jumpers in the OUT (towardthe left edge of the board) position. To untermi-Figure 3-5 - 168AO Network ID and Baud Rate SwitchesSetting the Baud Rate The I/O Network • 13

nate a MultiFlex, these jumpers must be set tothe IN (toward the center of the board) position.Figure 3-6 shows the termination jumper settingsfor all MultiFlex boards.Figure 3-6 - I/O Network Termination Jumper Settings14 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

4 I/O Board Input andOutput Setup4.1. The InputsThe inputs on a MultiFlex board are compatiblewith a wide range of analog and digital sensorsand transducers. In general, the inputs arecapable of reading analog voltage signals in therange of 0V to +7VDC and dry-contact (no outsidevoltage) digital sensors and switches.The specific types of input devices that mustbe used with MultiFlex is largely dependent onthe site controller MultiFlex is connected to;refer to the site controller’s user’s manual for afull list of compatible sensors and specific sensorwiring instructions.4.1.1. Connecting Sensors to InputBoardsWiring a sensor to the input points on a MultiFlexboard requires three steps:1. Connect the sensor’s signal wires to the twoterminals of an input point.2. Set the input type dip switch that correspondsto the point being connected.3. If necessary, connect the sensor to one of the5V or 12V power terminals.4.1.1.1. WiringAn input point on a MultiFlex board consistsof two terminals, as shown in Figure 4-1. One ofthese terminals, labeled “SIG,” reads the signalfrom the sensor, while the other, labeled “0v” iswhere the sensor’s ground and/or cable shieldwire is connected.Figure 4-1 - Input Board Points4.1.1.2. Input Wiring When Replacing16AI or CIO/8IO Boards WithMultiFlexIf the MultiFlex you are installing is replacingan existing 16AI, CIO, or 8IO, you will notbe able to simply unplug the input connectorsfrom the old board and plug them into the Multi-Flex. Doing so will cause the inputs to bereversed and the polarity to be swapped forpoints 1 through 8.You must either re-wire points 1 through 8 tothe proper place on the MultiFlex board, orobtain Multiflex input adapter cables (P/N 335-2301), as shown in Figure 4-2.

Sensor Wiring TypesSpecific wiring types are required for eachtype of sensor used with Einstein or RMCC.All Analog Temperature Sensors and Air Flow SensorsTemperature and air flow sensors are to bewired with shielded, 2 conductor, at least 22 GAwire (Belden # 8761 or equivalent).All Pressure Transducers, Humidity Sensors, and RefrigerationTransducersPressure and refrigeration transducers andhumidity sensors are to be wired with shielded, 3conductor, at least 22 GA wire (Belden #8771 orequivalent).Dew Point and Light Level SensorsThese sensors are to be wired with shielded,4 conductor at least 22 GA wire (Belden # 8729or equivalent).4.1.1.4. Input Type Dip SwitchesEach MultiFlex input point has an input typedip switch that must be set. Input type dipswitches are located in the switch banks labeledS1 and S2.The input type dip switch tells the inputboard whether or not the sensor connected to thepoint is a resistive type sensor. Generally, if thesensor or transducer supplies its own voltagesignal to the point, the dip switch should be setto the LEFT (OFF) position. If the sensor usesvariable resistance and requires voltage to besupplied to it from the input point, set the dipswitch to the RIGHT (ON) position. Dipswitches for unused points should be set to theRIGHT (ON) position.The exception to this rule is for CPC’s5VDC pressure transducers -- though theysupply their own voltage signal, the dip switchMUST be set to the RIGHT (ON) position.Figure 4-3 - Input Type Dip Switches for 16 Board4.1.1.5. Pulse Type InputsThe MultiFlex supports pulse accumulationinputs such as the kind supplied by some powertransducers. Pulse accumulation inputs pulse avoltage at a certain rate that corresponds to a value.If your site controller is an Einstein or a RE-FLECS BCU version 2.0 or above, you may connectpulse accumulation inputs to any point onthe board.If you have a REFLECS BCU with a versionnumber below 2.0, an RMCC (any version) or aBEC (any version), you may only connect a pulseaccumulation input to a single input on the MultiFlexboard.16 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

1. Connect the input to the point labeledINPUT #1. This is the only point on theboard that may accept this type of input.2. Locate switch #8 on the dip switch banklabeled S3 (the same one that sets inputboard network ID). Set switch #8 to the UP(ON) position. This will tell the REFLECSthat the input on point #1 is a pulse accumulationinput.4.1.2. Power ConnectionIf power is needed to operate the sensor, fourpoints are provided on the MultiFlex board thatsupply DC power: one +12VDC point, and three+5VDC points. See Figure 4-4 for the locationof these points.Figure 4-4 - Input Board Power Sources4.1.2.1. Current Ratings for On-BoardPower SourcesThe maximum current that may be drawnfrom the +12VDC terminal is 100 milliamps.The maximum current that can be drawn fromall three +5VDC terminals COMBINED is 50milliamps.4.1.2.2. Powering Sensors Requiring24VAC Off the Power TransformerSome sensors that requires 24VAC can bepowered off the MultiFlex’s own 24VAC powerconnection. To connect to the 24VAC powersource, connect the sensor’s power wires to terminalsAC1 and AC2.This can only be done with sensors that keepthe 24VAC signal isolated from its DC outputsignal (such as CPC’s Dew Point Probe). If theoutput signal is not isolated from the 24VACinput, you must use a separate transformer.4.1.3. Sensor Types for MultiFlexInput PointsBecause different controllers may be compatiblewith different sensor types, this manualcannot list all sensor types and how to wire themto a MultiFlex input point. Refer to your sitecontroller’s documentation for sensor wiringinformation.4.2. The Relay OutputsAll MultiFlex Combination I/O boards haveForm C relay contacts. Figure 4-5 shows how towire the three-terminal Form C contact.One wire of the two-wire connection shouldalways be connected to the middle terminal. Thesecond wire must either be connected to the N.C.terminal (if you want the path to be closed whenthe relay is de-energized) or the N.O. terminal (ifyou want the path to be open during power failure).The contacts you choose also affect what theboard’s fail-safe dip switch will need to be set tofor proper operation. Refer to Table 4-1 andTable 4-2 on page 18.RELAY ISCLOSEDON POWERRELAY ISOPEN ONPOWERFAILUREFAILUREN.C. N.O. N.C. N.O.Figure 4-5 - Form C Contact Wiring4.2.1. Output Fail-Safe Dip SwitchesWhen a controller calls for a MultiFlex relayoutput to be ON, it sends a command to the MultiFlexto turn the output to the ON state (signifiedby the output LED being ON). The behaviorThe Relay Outputs I/O Board Input and Output Setup • 17

of the relay when it is ON is determined by theposition of the fail-safe switch. The fail-safeswitches for the outputs are on a switch bank atthe bottom right corner the plug-in output module.Each switch corresponds to an output on theboard (switch #1 = output #1, etc.).Table 4-1 and Table 4-2 show how the failsafeswitch and Form C contacts should be configuredbased on how you want the output toperform during both normal operation and duringnetwork/power loss.Note: There are not many cases where youwould want a relay to be OPEN when called tobe ON. For most applications, you will want toset the fail-safe switch to UP so that an ON commandfrom the controller will close the relay.State of Normally Closed (N.C.)

Relay Output Ratings andFuse ProtectionRelay outputs on all MultiFlex CombinationI/O boards except for the 1616 family of boardsis rated for up to 240 VAC @ 1.2 amps, witheach relay fused with a 2A fast-blow 5mm x20mm fuse, Bussman GMA-2 or equivalent.The relays on the 1616L, 1616LAO, and1616LDO are not fused, and so the relays are deratedto a maximum of 24VAC with a maximumcurrent of 3.9 amps.4.3. The Analog OutputsAll varieties of the MultiFlex board that havean “AO” at the end of their model number(88AO and 168AO) have four analog outputsthat can provide a variable 0V - +10VDC signalto any of four variable-speed or variable-positiondevices. The maximum output current foreach point is 10 milliamps.18 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

The analog outputs have no hardware-basedfail-safe settings (fail-safes are set in the boardfirmware; see Section 6.1.9., Analog Fail-Safes). All that is required to connect a device toan analog point is to connect the “+” terminal tothe positive wire on the device and the “-” terminalto the negative (or ground) wire of thedevice.The 168DO has no hardware-based fail-safesettings (fail-safes are set up in the board firmware).All that is required is to connect the “+”terminal to the positive wire on the device andthe “-” terminal to the negative (or ground) wireof the device.DIGITALFigure 4-7 - MultiFlex Digital PointsFigure 4-6 - MultiFlex Analog Points4.4.

5 Board Status LEDsWhen a MultiFlex board is powered up, youwill be able to determine the operating status ofthe board by observing its status LEDs. Figure5-1 shows the location of the MultiFlex’s statusLEDs.Figure 5-1 - MultiFlex Status LED Locations5.1. Status LEDThe Status LED simply blinks GREEN onceper second to show that the board is poweredand operational. If this light is dark, the boardhas likely lost power.5.2. Tx and Rx LEDsThe Tx and Rx LEDs indicate when the MultiFlexis sending or receiving messages on theRS485 network.The Tx LED blinks once every time the MultiFlexsends a response to the Einstein orREFLECS. The Rx LED blinks once when theMultiFlex receives a message.If the MultiFlex is connected to the networkand set up to communicate with the controller,you should see these lights blinking regularly. Ifthey do not, there may be a problem with the network.5.3. Code A and Code B LEDsAll MultiFlex I/O boards except the Multi-Flex 16 have two LEDs labeled Code A andCode B. These LEDs indicate failure conditions.When these LEDs are OFF, there are no failuresactive. When one or both of these LEDs areblinking, there are failure conditions. The rate ofblinking indicates the type of failure:Code A Failure Conditions• Blinking fast (4 times/second) - There is a problemwith the flash memory or hardware clock on thisboard. This generally means the board is bad andmust be replaced.• Blinking slow (1 time/second) - The board is not receivingany messages addressed to it. This means ei-20 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

ther the I/O network is down or it has not yet beencommissioned in the Einstein or REFLECS NetworkConfiguration screen.Code B Failure Conditions• Blinking 2 times/second - This indicates the boardhas lost its configuration. For the MultiFlex I/Oboards, a board is considered “configured” if youhave specified input type settings and analog outputfail-safes. If Code B blinks at this rate on an operationalboard, it means the board must be reprogrammed.This light does not blink if the board is new or is usingthe unmodified default configuration.5.4. Relay Output LEDsEach relay output point on a MultiFlex hasan indicator LED that shows the status of theoutput. This LED is lit to show the output is ON,and unlit to show the output is OFF.The definition of ON and OFF in this case isdetermined by the position of the fail-safe dipswitch (see Table 4-1 and Table 4-2).Relay Output LEDs Board Status LEDs • 21

6 The MultiFlex Hand-Held Terminal InterfaceAll MultiFlex boards have a Hand-Held Terminalinterface, which can be used to view statusfor the board without having to use the site controller.Though different for each model of MultiFlex,the Hand-Held Terminal interface allowsyou to perform the same general functions:• View failure messages that relate to the MultiFlex• View the status of inputs (both in volts and in engineeringunits appropriate to the sensor type)• View the current state of relay outputs (ON or OFF)and analog outputs (both in volts and in percentage)• Override relay outputs to a fixed ON or OFF state,or override analog outputs to a fixed percentage• Configure set pointsPlugging In the Hand-Held TerminalThe Hand-Held Terminal plugs into theRJ11 jack on the MultiFlex base board (locatedon the bottom left side of the board, as shown inFigure 6-1). Press the Hand-Held Terminal connectorinto the jack until it snaps into place.When the connector is correctly seated, thescreen to the Hand-Held Terminal will displaythe message “CPC Handheld Terminal” and thenthe first screen of the MultiFlex interface.Figure 6-1 - MultiFlex HHT Jack Location6.1. MultiFlex I/O BoardHand-Held TerminalScreens6.1.1. NavigationThe Hand-Held Terminal interface consistsof a simple series of screens and menus. Figure6-2 shows a complete map of all screens for theMultiFlex board(s). The options for workingwith inputs, relay outputs, and analog outputsstem from an Input/Output Select Menu, whichwill give you only the options appropriate foryour board’s model type. This means if you arelooking at a MultiFlex 16, there will be nooptions listed for viewing relay or analog outputs.If you are using a MultiFlex 88 or 168,there will be no analog or digital output options.Scrolling Through The Hand-Held ScreensThe UP ARROW and DOWN ARROWkeys are used to scroll through the screens. Someof these screens, shown as dotted-line boxes inFigure 6-2, are read-only, meaning there are noeditable fields; others, shown as solid-lineboxes, are either menus that require you to entera selection or are configuration screens that haveone or more changeable fields.22 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06

Thenumbers shown here are read directly from thenetwork address dip switch settings on theboard. This screen does NOT allow you tochange the board numbers with the Hand-HeldTerminal; this must be done by setting the networkaddress dip switches. Refer to Section 3.3.,Network ID Numbers, for dip switch settinginformation.The MultiFlex will not display address numbersthat do not pertain to the model type. Inother words, a MultiFlex 16 will not show fieldswith the 8RO and 4AO address numbers, and an88 or 168 will not show a field for the 4AOaddress number.If an 16AI, 8RO, or 4AO field that is supposedto appear on this screen is not shown, it isbecause the board number dip switches for theseboard types are set to “0.” Set the 8RO and 4AOdip switch settings to a unique number (refer toSection 3.3.2., Numbering for MultiFlex CombinationI/O Boards.). The Hand-Held Terminalshould update within a few seconds and showthe 8RO and 4AO board numbers.6.1.4. SettingsSettings:Baud: 9600In 1 Pulse?

When a MultiFlex is in Relay OutputTest Mode, the output fail-safe dip switches maybe used to cycle the states of the relay outputs.The feature is designed to help manufacturers ofpanels test output wiring quickly and easilywithout need for a site controller or HHT.Relay Output Test Mode is available in thefollowing product versions:Board TypeVersion8RO-SMT output board 1.20F01andaboveMultiFlex 168, 88,168AO, and 88AO combinationinput/output boardsMultiFlex 168DO combinationinput/output boardswith digital outputsMultiFlex 1616LAO and1616LDO combinationinput/output boardMultiFlex 1616L combinationinput/output board w/o analog outputs1.60F01andabove1.60F01andabove1.30F01andabove1.20F01andaboveIn Relay Output Test Mode, fail-safe dipswitches 1-8 (located on the output board layerof MultiFlex I/O boards, and next to switch bankS1 on the 8ROSMT) can be used to change thestate of the relays.A fail-safe switch in the ON position willcause the corresponding relay to be energized(i.e. OPEN on the N.C. terminals, and CLOSEDon the N.O. terminals). A fail-safe switch in theOFF position will cause the relay to be de-energized(i.e. CLOSED on the N.C. terminals andOPEN on the N.O. terminals).The LED that shows the output state willalso be ON when the switch is ON and OFFwhen the switch is OFF.To exit Relay Output Test Mode, set theaddress switches S3 and S4 to any position otherthan “all OFF.” The fail-safe switches willresume normal operation.To activate Relay Output Test Mode forMultiFlex, set switches 1-8 on DIP Switch banksS3 and S4 to the OFF (LEFT) position. For8ROSMT, set switches 1-8 on DIP Switch bankS1 (NETWORK) to the OFF (DOWN) position.The board will enter Relay Output Test Mode.30 • MultiFlex I/O Board Operator’s Guide 026-1704 Rev 5 03-10-06
