INTRODUCTION

Description of Devices

The W7761A, Excel 10 Remote Input/Output device, provides auxiliary inputs and outputs for use with an Excel 10 Zone

Manager and Excel 10 controllers over the Echelon

tool. The W7761A device uses Echelon

LonWorks® communication technology and a new free topology twisted pair transceiver (FTT) for greater network installation flexibility. The Excel 10 RIO device can be combined with the Excel 10 Zone Manager (FTT), other Excel Controllers, and the Excel Building Supervisor, to provide a complete and low cost control solution for small to large commercial buildings.

The Q7750A Excel 10 Zone Manager is a communications interface that allows devices on the E-Bus network to communicate with devices on the standard EXCEL 5000® System C-Bus. Fig. 1 shows an overview of a typical system layout. The Q7750A also provides some control and monitoring functions.

Control Application

EXCEL 10 W7761A INPUT/OUTPUT DEVICE

The W7761A, Excel 10 Remote Input/Output device, provides auxiliary inputs and outputs for use with an Excel 10 Zone

Manager and Excel 10 controllers over the Echelon

LonWorks®E-Bus. The W7761A Remote Input/Output Device can be connected to outdoor air temperature and humidity sensors that can be used by other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. This would allow the controllers to use their physical inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control. The W7761A can be used to average many space temperature sensors that are located in a zone that is controlled by the W7750 Constant Volume AHU Controller. The W7761A device has 8 Digital Outputs which may be Discrete, Modulating or Floating. For example, this allows the control of lighting zones, miscellaneous exhaust or ventilation fans, miscellaneous pumps, and can enable freeze protection. See Fig. 2.

Control Provided

The W7761A was not intended to control staged or modulating heating/cooling coils, mixed air economizer dampers, or system fan/heat pump units. The W7761A contains inputs and outputs, but no control software. All control that would be associated with the inputs and outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable for VAV control, temperature control, or any control function that would require less than a 30 second update rate.

The Excel 10 W7761A RIO Device is available in one model. It contains 4 resistive inputs that can be configured for either 20Kohm NTC or PT3000 sensors, 2 voltage or current inputs, 4 digital inputs and 8 Digital Outputs (Triacs) which may be Discrete (maintained or momentary), Modulating (PWM) or Floating.

The W7761A consists of a single circuit board that is mounted in a sheet metal subbase and protected by a factory snap-on cover. The device mounts with two screws (see Fig. 3 or 4). Using DIN rail adapters (see Fig. 5) they can also be snapped onto standard EN 50 022 35 mm by 7.5 mm (1-3/8 in. by 5/16 in.) DIN rail. DIN rail is available through local suppliers. If using DIN rail also purchase from Augat Inc. part number 2TK2D DIN rail (adapter) two each for every device (see Fig. 5). Wires are attached to the screw terminal blocks on both sides of the device. Connection for operator access to the E-Bus is provided by plugging the SLTA connector cable into the communications jack.

A channel in the cover allows the device status LED to be visible when the cover is in place. There are no field-serviceable parts on the circuit board and, therefore,

The W7761A can be mounted in any orientation. Ventilation openings were designed into the cover to allow proper heat dissipation regardless of the mounting orientation. See Fig. 3 and 4.

Communications:

The W7761A Device uses a transformer-coupled communications port with differential Manchester-encoded data at 78 kilobits per second (kbs). The transformer-coupled communications interface offers a much higher degree of common-mode noise rejection while ensuring dc isolation.

Approved cable types for E-Bus communications wiring is Level IV 22 AWG (0.34 mm unshielded, twisted pair, solid conductor wire. For non-plenum areas, use Level IV 22 AWG (0.34 mm AK3781 (one pair) or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22 AWG (0.34 mm U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). (See Tables 6 and 8 for part numbers.) Contact Echelon Corp. Technical Support for the recommended vendors of Echelon approved cables.

The Free Topology Transceiver (FTT) supports polarity insensitive free topology wiring. This frees the system installer from the need to wire using a bus topology. Star, bus, mixed, and loop wiring are all supported by this architecture. The maximum E-Bus length when using a combination of star, loop, and bus wiring (singly terminated) is 1640 ft (500m) with the maximum node-tonode length of 1312 ft (400m). In the event that the total wire length is exceeded, then a Q7740A 2-Way Repeater or a Q7740B 4-Way Repeater can be used to allow the number of devices to be spread out as well as increasing the length of wire over which they communicate. The maximum number of repeaters per segment is one (on either side of the router). A Q7751A EBus Router can also be used to effectively double the maximum E-Bus length. The advantage of using the router is that it will segregate traffic to a segment while when using the repeater, all traffic is repeated on each segment. When utilizing a doubly terminated E-Bus structure, use a continuous daisy-chain with no stubs or taps from the main backbone, The maximum E-Bus length is 4593 ft (1400m) with the maximum node-to-node length of 3773 ft (1150m).

FTT networks are very flexible and convenient to install and maintain, but it is imperative to carefully plan the network layout and create and maintain accurate documentation. Unknown or inaccurate wire run lengths, node-to-node distances, node counts, total wire length, and misplaced or missing terminators can cause poor network performance. Refer to E-Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules.

Configurations

Each W7761A device can control or monitor a variety of different types of mechanical equipment. The W7761A was not intended to control staged or modulating heating/cooling coils, mixed air economizer dampers, or system fan/heat pump units. The W7761A contains inputs and outputs, but no control software. All control that would be associated with the inputs and outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable for VAV control, temperature control, or any control function that would require less than a 30 second update rate. It would be suitable to control miscellaneous exhaust or ventilation fans, lighting zones that are spread out through a building which need to be linked to a start/stop time program through the Zone Manager or to enable freeze protection. The W7761A device can be connected to outdoor air temperature and humidity sensors that can be used by other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. The W7761A can be used to monitor Occupancy, Window, Dirty filter, Indoor air quality, and Smoke control sensors. This allows the controllers to use their physical inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control. The W7761A can be used to

15 74-2699

EXCEL 10 W7761A INPUT/OUTPUT DEVICE

average many space temperature sensors that are located in a zone that is controlled by the W7750 Constant Volume AHU Controller.

Mixed-Output-Type Control

The W7761A Device can control mixed-output-types of applications such as PWM and staged control occurring simultaneously with Series 60 Floating Control.

Occupancy Sensor

Excel 10 W7761A device can be connected to an occupancy sensor through a digital input. This is a device, such as a passive infrared motion detector, that contains a dry contact (see following NOTE) closure to indicate whether or not people are present in the space. The Excel 10 W7761A Device expects a contact closure to indicate the space is Occupied. See Fig. 18 in Application Step 4, Prepare Wiring Diagrams, for details on wiring connections. This occupancy sensor can then be bound to other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. This would allow the other Excel 10 controllers to use their physical inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control.

NOTE: The Excel 10 Controllers (W7750 CVAHU and W7761A RIO) have limited power available (only 9 mA at 4.8 volts) for

The recommended devices for use with the Excel 10 W7750 Controller and W7761A Device are the EL7628A1007 Ceiling Mounted Infrared or the EL7680A1008 Wall Mounted Wide View Infrared Occupancy Sensors. If ultrasonic sensors are required, the EL7611A1003 and the EL7612A1001 Occupancy Sensors are recommended. An EL76XX Power Supply/Control Unit is required for use with these occupancy sensors. The EL7630A1003 can power up to four sensors, and is multi-tapped for several line voltages. The EL7621A1002 can power three sensors and it connects to 120 Vac line voltage. The EL7621A1010 can also power three sensors but it connects to 277 Vac line voltage.

checking the digital inputs for contact closures. It is very important that the device used contains high quality, noncorroding contacts with resistivity that does not degrade; that is, increase over time. Use noble metal (such as gold or silver), pimpled or sealed contacts to assure consistent, long-term operation.

Window Open/Closed Digital Input

Excel 10 W7761A device can be connected to a window sensor to indicate whether a window in the space was opened. The Excel 10 W7761A device can be connected to a dry contact (see the NOTE for the Occupancy Sensor and Fig. 18 in Application Step 4. Prepare Wiring Diagrams, for details) or a set of contacts wired in series (for monitoring multiple windows) to verify that the window(s) are closed. This window(s) sensor can then be bound to other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. The algorithm in the other Excel 10 controllers expects a contact closure to indicate the window is closed. If an open window is detected, the algorithm in the other Excel 10 controllers changes the mode of operation to FREEZE_PROTECT, which shuts down the control functions, and watches for low space temperature conditions. The freeze protection setpoint is 46.4°F (8°C), and the frost alarm occurs at 42.8°F (6°C).

Wall Module Options

As previously discussed, there are five basic varieties of the T7770. There is one variety of the PT3000 sensor and the T7780 DDWM (see the Product Names and the Construction sections). The T7770A,B,C,D 20Kohm NTC sensor—(current feature that can be used with the RIO Device) and one PT3000 sensor can be configured on any of the four resistive inputs. The T7780 is an E-Bus node and would not be directly connected to the RIO Device.

Dirty Filter Monitor

The air filter in the air handler can be monitored by the W7761A RIO device and an alarm issued by the Zone Manager when the filter media needs replacement. The two methods of monitoring the filter are:

1. Connecting a differential pressure switch to a digital input on the W7761A.

2. Wiring a 2-to-10V differential pressure sensor to a voltage input on the W7761A. If the analog input sensor is used, its measured value 0 to 5 inw (0 to 1.25 kPa) is compared to a user-selectable setpoint. The comparison is done in the Zone Manager —valid range: 0 to 5 inw (0 to 1.25 kPa), and the Dirty Filter alarm is issued when the pressure drop across the filter exceeds the setpoint.

Indoor Air Quality (IAQ)

The Excel 10 W7761A device can monitor IAQ using one of two different methods of detecting poor air quality. The first is with an IAQ switch device connected to a digital input on the W7761A, where a contact closure indicates poor air quality, and an alarm can be issued by the Zone Manager. The device can detect poor air quality using any desired measure such as CO VOC, CO, etc. The second method, is through an analog input that connects to a CO

from this sensor (0 to 2000 ppm) is compared to a user-selectable setpoint (the comparison is done in the Zone

of CO

Manager —valid range: 0 to 2000 ppm), and an IAQ alarm can be issued when the CO sensor that is connected to the W7750 RIO, can be bound to other W7750 CVAHU Excel 10 controllers on the E-Bus.

APPLICATION STEPS

Overview

The seven application steps shown in Table 3 are planning considerations for engineering an Excel 10 W7761 Remote Input/Output Device. These steps are guidelines intended to aid understanding of the product I/O options, bus arrangement choices and the Excel 10 W7761A Devices role in the overall EXCEL 5000® System architecture.

1 Plan The System 2 Determine Other Bus Devices Required 3 Lay Out Communication and Power Wiring 4 Prepare Wiring Diagrams 5 Order Equipment 6 Configure Devices 7 Troubleshooting

Step 1. Plan The System

Plan the use of the W7761A Devices according to the job requirements. Determine the location, functionality and sensor or actuator usage. Verify the sales estimate of the number of W7761A Devices and the number and type of output actuators and other required accessories. When planning the system layout, consider potential expansion possibilities to allow for future growth. Planning is very important to be prepared for adding HVAC systems and controllers in future projects. T7770A,B,C,D Wall Modules (sensor—current feature that can be used with the RIO Device)can be installed as either hardwired I/O-only devices or additional wiring can be run to them (for the E-Bus network ) to allow a CARE/E-Vision operator terminal to have access to the E-Bus. The application engineer needs to determine how many wall modules or other input sensors are required. This information is required during installation to ensure that the proper number and type of wires are pulled to the wall modules, and the building operators are informed about where they can plug in to the E-Bus network with a portable operator terminal (see Fig. 8 through 10).

The FTT communication loop, (E-Bus) between controllers is a free topology wiring scheme that supports star, loop, and/or bus wiring. Refer to the E-Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules. See Application Step 3. Lay Out Communications and Power Wiring, for more information on bus wiring layout, and see Fig. 16 through 19 in Application Step 4. Prepare Wiring Diagrams, for wiring details. The application engineer must review the Direct Digital Control (DDC) job requirements. This includes the Sequences of Operation for the Excel 10 controllers, and for the system as a whole. Usually there are variables that must be passed between the W7750 (CVAHU), Q7750A Zone Manager, W7761 (RIO), and other Excel 10 controller(s), or central plant controller(s) that are required for optimum system-wide operation. Typical examples are the TOD Occ/Unocc signal, the outdoor air temperature, demand limit control signal, and smoke control mode signal.

17 74-2699

EXCEL 10 W7761A INPUT/OUTPUT DEVICE

It is important to understand these interrelationships early in the job engineering process to ensure implementing when configuring the controllers. (See Application Step 6. Configure Devices, for information on the various Excel 10 parameters and on Excel 10 point mapping.)

Step 2. Determine Other Bus Devices Required

A maximum of 62 nodes can communicate on a single E-Bus segment. Each W7761A (RIO), W7750 (CVAHU), W7751 (VAV) Controller or T7780 Wall Module constitutes one node. If more nodes are required, a Q7751A Router is necessary. Using a router allows up to 125 nodes, divided between two E-Bus segments. The router accounts for two of these nodes (one node on each side of the router); a Q7750A Excel 10 Zone Manager takes one node and two nodes are available for operator terminal nodes, leaving 120 nodes available for Excel 10 Controllers and T7780 Wall Modules. All 120 controllers and T7780 Wall Modules are able to talk to each other through the router. A Q7750A Excel 10 Zone Manager is required to connect the E-Bus to the standard EXCEL 5000® System C-Bus. Each Excel 10 Zone Manager can support no more than 120 Excel 10 Controllers and T7780 Wall Modules. This limit is set in the Excel 10 Zone Manager database as an absolute maximum. Each E-Bus segment is set up with two unused nodes to allow for a CARE/E-Vision or Hand Held Tool (HHT) to be connected to the E-Bus. Multiple CARE/E-Vision or HHT terminals can be connected to the bus at the same time. Table 4 summarizes the E-Bus segment configuration rules.

Table 4 . E-Bus Configuration Rules And Device Node Numbers.

One E-Bus Segment Example Maximum Number of Nodes Equals 62

One Q7750A Excel 10 Zone Manager 1 node

Port for operator terminal access (CARE/E-Vision or HHT) 1 node

Maximum number of Excel 10s and T7780s 60 nodes (Only T7780 Wall Modules are E-Bus nodes)

Total 62 nodes

Two E-Bus Segments Example Maximum Number of Nodes Equals 125

One Q7750A Excel 10 Zone Manager 1 node

One Q7751A Router 2 nodes (1 in each Bus Segment)

Ports for operator terminal access (two CARE/E-Vision or HHT

terminals)

Maximum number of Excel 10s and T7780s in segment number

Refer to the E-Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules and the maximum wire length limitations. If longer runs are required, a Q7740A 2-way or Q7740B 4-way repeater can be added to extend the length of the E-Bus. A Q7751A Router can be added to partition the system into two segments and effectively double the length of the E-Bus. Only one router is allowed with each Excel 10 Zone Manager and each network segment can have a maximum of 1 repeater. In addition, all E-Bus segments require the installation of a Bus Termination Module for a singly terminated E-Bus or two Bus Termination Modules for a doubly terminated E-Bus. For more details on E-Bus termination, refer to the E-Bus Wiring Guidelines form, 74-2865, or see Application Step 3. Lay Out Communications and Power Wiring, and the E-Bus Termination Module subsection in Application Step 4.

Step 3. Lay Out Communications and Power Wiring

E-Bus Layout

The communications bus, E-Bus, is a 78-kilobit serial link that uses transformer isolation and differential Manchester encoding. Approved cable types for E-Bus communications wiring is Level IV 22 AWG (0.34 mm unshielded, twisted pair, solid conductor wire. For nonplenum areas, use Level IV 22 AWG (0.34 mm AK3781 (one pair) or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22 AWG (0.34 mm U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). See Tables 9 and 10 for part numbers. Contact Echelon Corp. Technical Support for the recommended vendors of Echelon approved cables. The FTT communications bus, E-Bus, supports a polarity insensitive, free topology wiring scheme that supports star, loop, and/or bus wiring. E-Bus networks can be configured in a variety of ways, so refer to the E-Bus Wiring Guidelines form, 74-2865 for a complete description of network topology rules and Table 4. Fig. 9 and 10 depict two typical E-Bus network topologies; one as a singly terminated bus segment that has 60 nodes or less, and one showing a doubly terminated segment. The bus configuration is set up using the Network Manager tool from within CARE (see the CARE User’s Manual form, 74-5587 or Excel E-Vision User’s Guide form, 74-2588).

Power Wiring

A power budget must be calculated for each Excel 10 W7761 Device to determine the required transformer size for proper operation. A power budget is simply the summing of the maximum power draw ratings (in VA) of all the devices to be controlled by an Excel 10 W7761 Device. This includes the device itself, the equipment actuators (ML6161, or other motors) and various contactors and transducers, as appropriate, for the Excel 10 configuration.

Power Budget Calculation Example

The following is an example power budget calculation for a typical W7761A Excel 10 Device. Device VA Information Obtained from the Excel 10 W7761 6.0 VA W7761 Device Specification Data

The Excel 10 System example requires 29.9 VA of peak power; therefore, a 40 VA AT72D Transformer is able to provide ample power for this device and its accessories. Alternatively, a 75 VA AT88A Transformer could be used to power two Excel 10 Systems of this type, or a 100 VA AT92A Transformer could be used to power three of these controllers and meet NEC Class 2 restrictions (no greater than 100 VA). See Fig. 12 through 14 for illustrations of power wiring details. See Table 5 for VA ratings of various devices.

TOTAL: 29.9 VA

Table 5 . VA Ratings For Transformer Sizing.

Device Description VA

For contactors and similar devices, the in-rush power ratings should be used as the worst case values when performing power budget calculations. Also, the application engineer must consider the possible combinations of simultaneously energized outputs and calculate the VA ratings accordingly. The worst case, that uses the largest possible VA load, should be determined when sizing the transformer.

Line Loss

Excel 10 Controllers must receive a minimum supply voltage of 20 Vac. If long power or output wire runs are required, a voltage drop due to Ohms Law (I x R) line loss must be considered. This line loss can result in a significant increase in total power required and thereby affect transformer sizing. The following example is an I x R line-loss calculation for a 200 ft (61m) run from the transformer to a W7761 Device drawing 37 VA using 18 AW G (1.0 mm

) wire. The formula is: Loss = [length of round-trip wire run (ft)] x [resistance in wire (ohms per ft)] x [current in wire (amperes)] From specification data: 18 AWG twisted pair wire has 6.52 ohms per 1000 feet. Loss = [(200 ft) x (2 - round-trip) x (6.52/1000 ohms per ft)] x [(37 VA)/(24V)] = 4.02 volts This means that four volts are going to be lost between the transformer and the device; therefore, to assure the device receives at least 20 volts, the transformer must output more than 24 volts. Because all transformer output voltage levels depend on the size of the connected load, a larger transformer outputs a higher voltage than a smaller one for a given load. Fig. 11 shows this voltage load dependence. In the preceding I x R loss example, even though the device load is only 37 VA, a standard 40 VA transformer is not sufficient due to the line loss. From Fig. 11, a 40 VA transformer is just under 100 percent loaded (for the 37 VA device) and, therefore, has a secondary voltage of 22.9 volts. (Use the lower edge of the shaded zone in Fig. 11 that represents the worst case conditions.) When the I x R loss of four volts is subtracted, only 18.9 volts reaches the device, which is not enough voltage for proper operation. In this situation, the engineer basically has three alternatives:

1. Use a larger transformer; for example, if an 80 VA model is used, see Fig. 11, an output of 24.4 volts minus the four volt line loss supplies 20.4V to the device. Although acceptable, the four-volt line-loss in this example is higher than recommended. See the following

IMPORTANT

2. Use heavier gauge wire for the power run. 14 AWG (2.0 mm using the preceding formula, gives a line-loss of only 1.58 volts (compared with 4.02 volts). This would allow a 40 VA transformer to be used. 14 AWG (2.0 mm

) wire is the recommended wire size for 24 Vac wiring.

) wire has a resistance of 2.57 ohms per 1000 ft which,

3. Locate the transformer closer to the device, thereby reducing the length of the wire run, and the line loss.

The issue of line-loss is also important in the case of the output wiring connected to the Triac digital outputs. The same formula and method are used. The rule to remember is to keep all power and output wire runs as short as practical. When necessary, use heavier gauge wire, a bigger transformer, or install the transformer closer to the device.

IMPORTANT

21 74-2699

EXCEL 10 W7761A INPUT/OUTPUT DEVICE

No installation should be designed where the line loss is greater than two volts to allow for nominal operation if the primary voltage drops to 102 Vac (120 Vac minus 15 percent).

To meet the National Electrical Manufacturers Association (NEMA) standards, a transformer must stay within the NEMA limits. The chart in Fig. 11 shows the required limits at various loads. With 100 percent load, the transformer secondary must supply between 23 and 25 volts to meet the NEMA standard. When a purchased transformer meets the NEMA standard DC20-1986, the transformer voltage-regulating ability can be considered reliable. Compliance with the NEMA standard is voluntary. The following Honeywell transformers meet this NEMA standard:

All field wiring must conform to local codes and ordinances. To maintain NEC Class 2 and UL ratings, the installation must use transformers of 100 VA or less capacity. For multiple controllers operating from a single transformer, the same side of the transformer secondary must be connected to the same input terminal in each device and the ground terminals (1 on the W7761A) must be connected to a verified earth ground for each device in the group. See Fig. 13. (Device configurations are not necessarily limited to three devices per transformer.) For the W7761A Device (which has Triac outputs), all output devices must be powered from the same transformer as the one powering the Excel 10 W7761A Device. Use the heaviest gauge wire available, up to 14 AWG (2.0 mm2) with a minimum of 18 AWG (1.0 mm2) for all power and earth ground connections. To minimize EMI noise, do not run Triac output wires in the same conduit as the input wires or the E-Bus communications loop. Unswitched 24 Vac power wiring can be run in the same conduit as the E-Bus cable.

•

ground is essential for W7761A operation. Ideally, connect the earth ground to the ground bus at a motor control center or circuit breaker panel. However, if the nearest ideal earth ground is inaccessible, consider an alternate source for earth ground. Metal water pipe is generally a good ground, but do not use sprinkler pipe if prohibited by local codes. Attention must be given when duct work, conduit, or rebar are to be considered as ground sources. It is the responsibility of the installer to assure that these structures are tied back to a known earth ground.

Step 4. Prepare Wiring Diagrams

General Considerations

The purpose of this step is to assist the application engineer in developing job drawings to meet job specifications. Wiring details are included for the W7761A device the T7770A,B,C,D wall module (sensor—current feature that can be used with the RIO Device) and the T7780 DDWM. The drawings detail I/O, power, and communication bus wiring connections.

NOTE: For field wiring, when two or more wires are to be attached to the same connector block terminal, be sure to twist

them together. Deviation from this rule can result in improper electrical contact. See Fig. 15.

The connector block terminals on the W7761A and on the T7770 accept 14 through 22 AWG (2.0 to 0.34 mm

W7761A Devices

Fig. 16 through 20 illustrate W7761A Device wiring for various configurations. Connections to the wall module terminals (4 through 6) and the communications terminals (14 and 15) are made at terminal blocks. Connection for access to the E-Bus is provided by plugging the connector into the communications jack. NOTE: If an Excel 10 W7761A Device or Zone Manager is not connected to a good earth ground, the device internal transient

protection circuitry is compromised and the function of protecting the device from noise and power line spikes cannot be fulfilled. This can result in a damaged circuit board and require replacing the device.

Alarms

When an Excel 10 has an alarm condition, it reports it to the central node on the E-Bus (typically, the Excel 10 Zone Manager). See Table 9. Information contained in an alarm message is:

•

Subnet Number: E-Bus subnet that contains the Excel 10 node that has the alarm condition. Subnet 1 is on the Zone Manager side of the router; Subnet 2 is on the other side.

•

Node Number: Excel 10 node that has the alarm condition (see Network Status).

•

Alarm Type: Specific alarm being issued. An Excel 10 can provide the alarm types listed in Table 9.

Broadcasting the Service Message

The Service Message allows a device on the E-Bus to be positively identified. The Service Message contains the device ID number and, therefore, can be used to confirm the physical location of a particular Excel 10 in a building. There are two methods of broadcasting the Service Message from an Excel 10 W7761A Device. One uses a hardware service pin button on the side of the device (see Fig. 24). The other involves using the PC Configuration tool, as follows.

The commissioning tool is used to perform the ID Assignment task (see the E-Vision User’s Guide form, 74-2588).

Appendix A. Using E-Vision to Commission a W7761 Device.

CARE/E-Vision must be used to configure the W7761 device. The inputs and outputs will be configured through the application selection menu (see E-Vision user guide form, 74-2588). The RIO does not contain control loops for directly controlling the digital outputs, therefore the Zone Manager or some other device has to be bound to the outputs to perform the control function. Refer to the CARE User’s Manual form, 74-5587 to add Control Strategy, Switching Logic, or Time Programs for control of the RIO digital outputs. Refer to the E-Vision user guide (form, 74-2588 for the RIO commissioning procedure and updating/downloading of the Zone Manager files.

When calibrating voltage/current sensors on the W7761A, the offset amount entered by the user is in volts, regardless of the inputs actual engineering units. See Appendix E for information on how to derive the proper voltage value to enter as an offset during calibration.

CUSTOM MAPPING

The RIO default CARE plant contains all available points that are supported on the RIO device. If the RIO plant was customized by deleting unused points, then the Custom mapping feature will have to be used to add points back into the plant so that they can be used or monitored by other devices. The following procedures will describe the Custom mapping process for adding analog/digital inputs and digital outputs.

ADDING ANALOG INPUTS - ENTHALPY (4 to 20 mA)

To add an enthalpy (outdoor or return air) sensor to an RIO plant, the user must add a software point (pseudo analog) that can be mapped to the actual hardware input through the Custom Mapping function of E-Vision. The following procedure will instruct the user on adding the pseudo analog and using the Custom Mapping function. This allows the enthalpy input to be used with other Excel 10 controllers (referenced) on the E-Bus, used in Zone Manager control strategy or switching logic, or be used with Excel 5000 controllers on the C-Bus.

ADDING DIGITAL OUTPUTS

See Table A-3 for the supported digital output types that can be connected to the RIO Device. The user must add a software point (pseudo analog) that can be mapped to the actual hardware output through the Custom Mapping function of E-Vision. The following procedure will instruct the user on adding the pseudo analog and using the Custom Mapping function so that the Digital Output can be used in the Zone Manager control strategy or switching logic, or be used with Excel 5000 controllers on the C-Bus.

With CARE running, open an existing RIO plant. The user can go into either switching logic or control strategy to add the pseudo analog point. If the user does not have an existing control loop through control strategy, use switching logic to add the pseudo point, otherwise a control loop will have to be created along with unnecessary RACL to add the point. This procedure will use switching logic to add the pseudo analog point. With the RIO plant having the focus, go into switching logic. Select the dialog box will be displayed.

Common Operations

The Excel 10 W7761A Device contains inputs and outputs, but no control software. All control that would be associated with the inputs and outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable for VAV control, temperature control, or any control function that would require less than a 30 second update rate. The analog and digital sensors could be shared or bound to other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. This would allow the other Excel 10 controllers to use their physical inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control.

Room Temperature Sensor (RmTemp)

42 74-2699

EXCEL 10 W7761A INPUT/OUTPUT DEVICE

The T7770A,B,C,D wall module is the room space temperature sensor—(current feature that can be used with the RIO Device). When it is configured, it provides the temperature input that can be shared with the W7750 or W7751 controllers. If there are multiple space sensors in a area controlled by one W7750 CVAHU, then the space temperatures can be wired into the W7761A controller and mapped to the Zone Manager. The Zone Manager can average all of the space temperatures and then have that value can be bound to the W7750 controlling that area.

Window Sensor (StatusWndw)

The digital input for a window contact can be wired into the W7761A device and then bound to a W7750 CVAHU to disable its temperature control algorithm if someone has opened a window or door in the room or area that the W7750 is serving. When a window is detected to be Open (digital input contacts Open equals window open), the normal temperature control is disabled, and the W7750 Controller enters the Freeze Protect mode. Freeze Protect mode sets the space setpoint to 50 °F (10°C) and brings on the fan and heat if the space temperature falls below this setpoint. Normal temperature control resumes on window closure.

Dirty Filter Monitor

The air filter in the air handler can be monitored by a digital input in the W7761A and an alarm issued by the Zone Manager when the filter media needs replacement. The two methods of monitoring the filter are:

1. A differential pressure switch whose contacts are connected to a digital input on the W7761A and;

2. A 2 to 10V differential pressure sensor wired to a voltage input on the W7761A. If the analog input sensor is used, its measured value 0 to 5 inw (0 to 1.25 kPa) is compared to a user-selectable setpoint in the Zone Manager, the comparison is done in the Zone Manager - valid range: 0 to 5 inw (0 to 1.25 kPa), and the Dirty Filter alarm is issued by the Zone Manager when the pressure drop across the filter exceeds the setpoint.

Series 60 Modulating Control

Series 60 Control is also commonly referred to as Floating Control. The Excel 10 W7761A Device can drive Series 60 type actuators to control a modulating damper or valve actuator. The W7761A device contains no control software, so these outputs would have to be bound to either the Zone Manager or other Excel 10 controllers. When floating control is used, the full-stroke motor drive time of the actuator must be entered into the configuration parameter DO1FlSpeed (for output 1), DO2FlSpeed (for output 2). When Floating control is configured, two digital outputs are required, so the user has to change the configuration parameter for the appropriate digital outputs.

Pulse Width Modulating (PWM) Control

The Excel 10 W7761A device can drive a PWM-type actuator to control a modulating actuator. The W7761A device contains no control software, so these outputs would have to be bound to either the Zone Manager or other Excel 10 controllers. PWM control positions the actuator based on the length, in seconds, of the pulse from the digital output. The controller outputs a pulse whose length consists of two parts, a minimum and a maximum. The minimum pulse time represents the analog value of zero percent (also indicates a signal presence) and the maximum pulse length that represents an analog value of 100 percent. If the analog value is greater than zero percent, an additional time is added to the minimum pulse time. The length of time added is directly proportional to the magnitude of the analog value. If PWM control is used, the configuration parameters for the PWM operation must be specified. These parameters are DO1PWMPeriod and PWMZeroScale, and PWMFullScale.

Example: To find the pulse width of a valve actuator (for example stroke mid position - 50 percent) with the PWMZeroScale =

0.1 seconds, PWMFullScale = 25.5 seconds, and the PWMPeriod = 25.6 seconds. There are 256 increments available, so the number of increments required for 50 percent would be (0.5 X 256) or 128. The time for each increment for this industry standard pulse time is 0.1 seconds. The pulse width is the minimum time (0.1 second) + the number of increments (128 times the seconds added 0.1) = 12.9 seconds. The W7750B Controller would command the valve output on for 12.9 seconds every

25.6 seconds to maintain the valve position at 50 percent.

Indoor Air Quality (IAQ) Override

The Excel 10 W7761A Device can monitor an IAQ sensor and that input can be bound to a W7750 CVAHU Controller that supports an IAQ override feature, that upon detection of poor air quality in the space, allows the economizer dampers to be opened above the standard minimum position setting to a value set in EconIAQPos (parameter located in W7750). Two different methods of detecting poor air quality are supported, The first is by using an IAQ switch device connected to a digital input on the W7761A Device, where a contact closure indicates poor air quality. This digital input would then be bound to the W7750 Controller that is serving the area being monitored and would initiate the IAQ override mode. The second is through an analog input that connects to a CO mapped into the Zone Manager where it is compared to a setpoint (parameter located in the Zone Manager). When the CO

Sensor (0 to 10V). The measured value of CO2 from this sensor (0 to 2000 ppm) is

level is higher than the setpoint, the Zone Manager can initiate an IAQ alarm. A pseudo digital point in the Zone Manager can be bound to the W7750 CVAHU Controller which can initiate the IAQ override mode.

Thi s can be mapped as one of the three output types (Discret e, Modulate, Float_Open, or Float_Close) by DO3Type. If the user selects an enumerated value of Discret e2 for DO3Type, this value would be stored in (DO2). Then the DestOut4Cm d will command DO2.

nviInUse is used by a management node to indicate to all other management nodes that it is logged on, to the Excel 10 node and that they should not t ry to interact with any of the Excel 10s net work variabl es. Before the managem ent node reads or writes any network variables, the management node checks nviInUse for a zero value meaning no other managem ent nodes are already logged on and that a management node may log on, to the node. Then the managem ent node writes a number, 1 through 65534, to nviInUse and periodically writes the sam e val ue to indicate that the managem ent node is still logged on. If there are no writes m ade to nviInUse for approximately 60 s econds, then the Excel 10 reset s nviInUse to zero to automatically l og of f the management node. B efore interacting with any network variables, the managem ent node verifies that the nviInUse has not changed. The management node logs off by writing 0 to nviInUse. During power up, an application restart, or return to on-line from off-li ne, the Excel 10 sets nviInUse to 65535 to i ndi cate to the management node that it has returned to on-line.

A diagnosti c tool may poll nvoError for all of the current errors. nvoError uses one bit for each possi ble error condition. nvoError contains all the detected current errors even though they may be suppressed for reporting by nvoAlarm. There is a correspondence between the error conditi ons and alarm types. nvoError includes sensor failure errors and input network variable failure detect errors. Any sensor failure errors result i n a SENSOR_FAILURE alarm. Fai l ure to receive any bound network variable periodically results i n an INPUT_NV_FAILURE alarm. nvoError tells which sensor(s) or network variable(s) have failed.

X M X AILowLimit: This is the low limit value or the lowest value that will be displayed for

this sensor. This value must be between the AIOutputRLow and AIOutputRHigh and lower than the value specified for AIUpperLimit.

X M X AIOutputRHigh: This is the equivalent temperature degrees F (degrees C) value for

the resistance entered for AIResHigh. Using the resistance example for AIResHigh of 48,000 ohms, you would enter the equival ent temperature of 45.0 degrees F (7. 2 degrees C) for the AIOutputRHigh value.

X M X AIOutputRLow: This is the equi val ent temperature degrees F (degrees C) value for

the resistance entered for AIResLow. Using the resistance example for AIResLow of 11,520 ohms, you would enter the equivalent temperature of 99.0 degrees F (37.2 degrees C) for the AIOutputRLow value.

The user can select between a PT3000 (Custom_PT3000) or a 20 Kohm NTC (Custom_20 Kohm NTC) s ensor. This value is specified in ohms with LS B in 10 Ohms. This m eans that if your high resist ance value for a 20 Kohm NTC sensor was 48,000 ohms, 45.0 degrees F (7.2 degrees C), the value that would be entered for AIResHigh would be 4800 (the resistance value divided by ten).

X M X DO1PWMPeriod is a intermittent voltage pul se whose width varies in proportion to

the desired actuator posit i on. The PWM signal has t hree parameters that have to be configured in order for the output t o f unction correctly. The period, i s the overall pulse lenegth in seconds. The percent _time (signal presence) is the zero percent position of the actuator output. The actuator requires this si gnal (pul se width) sent once every period, so that it knows that it is still connected to the controller and where the zero position starts. The vari abl e width (del ta_time) portion is inc remented in proportion to the signal percentage. There are 255 increments available (for example 0.1 second). Thus, the pulse width will be the minimum width (percent_time) plus the number of increments (delta_t i me/ 255). The smalles t time that can be us ed with t he RIO controller is 0.1 second. An example stroke at m i d position is: 0.1 sec ond (percent_time) + 128 x 0.1 (255/0.5 - 50 percent position) = 12.9 seconds. The period would equal the percent_time plus the delta_time (for example 0. 1 seconds) + 255 x

0.1 seconds = 25.6 seconds . X M X DO1PWMZero: Refer to the description for DO1PWMPeriod. X M X DO1PWMFull: Refer to the description for DO1PWMPeriod.

X X M P DestManMode: is an input which is used t o manually set the physical outputs.

DestManMode remains unchanged until anot her mode has been commanded or an application restart has been performed. The valid enumerated val ues are: MODE_ENABLE enables the node so t hat the RIO controls the physi cal outputs as the normal mode. MODE_ENABLE is the default s t ate after power is restored or an application restart occurs. If the mode was MANUAL and DestManMode is set to MODE_ENABLE, the node then goes through application restart. MODE_DISABLED sets the node into the DISABLED mode. The alarm NODE_DISABLED is initiated, and the physical outputs are turned off. The physical inputs, network variable inputs, and network variable outputs are s till functioning when the node is in the DISABLED mode. MODE_MANUAL sets the node into the MANUAL mode. The alarm NODE_DISABLED is initiated, and the physical outputs are c ont rolled manually as commanded by DestManMode. The nodes configuration variables and DestManMode are used to set valves, dampers, and/or digital output t o the desired manual positions or s t ate(s). The physical inputs , network variable inputs, and network variable outputs are still functioning when the node is in t he MANUA L mode. SUPPRESS_ALARMS causes AlarmType to be set to ALARM_NOTIFY_DISABLED, and AlarmTypeLog to no longer record alarms. If alarms are suppressed, UNSUPPRESS_ALARMS causes AlarmType and AlarmTypeLog to be returned to reporting alarms. See nvoA l arm for more details. All unspecified values are t he same as MODE_ENABLE.
