1.4.2 The E2 Echelon Lonworks Network The E2 is also compatible with a network platform called Lonworks. This is most commonly referred to as “the Echelon Network,” after the company who invented the platform, the Echelon Corporation. In general, peripherals with control functions — such as case controllers, rooftop HVAC controllers, and other E2 RX and BX units — are interconnected on the Echelon Network.
1.5 Documentation Overview The E2 RX and BX controllers are among the most versatile and customizable control system products available on the market. Because of the enhanced capabilities of the E2s, programming, installation, and operation of E2 and its accompanying peripherals are supported by several different Emerson Retail Solutions publications.
cuit breakers that are flipped from OFF to ON and from ON to OFF by commands sent from E2 through MODBUS or a Square D Smart Breaker Gateway board. Refer to this manual for more information on the Square D Breaker Panel application. • Eaton Breaker Control Manual (P/N 026-1709) E2 can communicate directly with Eaton's Breaker Control Bus (BCB) modules. Communication with the E2 (minimum E2 firmware rev. 2.
2 Hardware Overview This section gives an overview of the E2, the hardware, and how it communicates across the I/O and Echelon Networks to control an entire system. 2.1 E2 Hardware The E2 controller is programmed to monitor and command all aspects of a refrigeration or building environmental control system. The E2 uses both an RS485 I/O Network and a LonWorks Network to gather data from input devices, communicate with other E2s, and activate or deactivate loads.
2.1.1 (CPU) E2 Main Processor Board 2.1.3 E2 Keypad Figure 2-4 - E2 Keyboard Figure 2-2 - E2 CPU The E2 CPU or main processor board (Figure 2-2) contains the CPU, Ethernet port, and memory used for logging. The coin battery for the E2 is located on this board and protects log and alarm data during power loss. The main processor board connects to the PIB via a ribbon cable. The RX- and CX-100 versions support monochrome display only.
Main Board (CPU) LEDs Status Green (D1 General Status LED for E2 and Blank Face E2) 1 blink every two seconds (1 second ON, 1 second OFF): Main board is operating normally. Solid ON: E2 is booting up. Faster blinks per second: Indicates an error condition with the hardware or firmware. Green (D18 Boot Status LED) ON: E2 is booting up. 2.2 I/O Network Boards and Peripherals 2.2.

Table 2-7 shows the available models of MultiFlex combination input/output boards with description and part numbers. P/N Model Name 810-3063 MultiFlex 88AO 8 analog/digital inputs, 8 relay outputs, 4 analog outputs 810-3064 MultiFlex 88 8 analog/digital inputs, 8 relay outputs 810-3065 MultiFlex 168AO 16 analog/digital inputs, 8 relay outputs, 4 analog outputs 810-3066 MultiFlex 168 16 analog/digital inputs, 8 relay outputs.
2.2.2.3 MultiFlex CUB The MultiFlex Condensing Unit Board (CUB) is a “smart” input/output board designed to control single condensing units. A single condensing unit is a self-contained compressor and condenser bearing unit which controls refrigeration in a single case line-up or walk-in cooler. The MultiFlex CUB uses the same general hardware configuration as a MultiFlex 168AO.
The PAK can control up to 4 condenser fan groups containing up to 8 total condenser fans. The PAK condenser control strategy is sequential TD control with setpoint/deadband using ON and OFF delays. The PAK has a compressor/condenser interlock feature that will override TD control and force the condenser fans to stage off using the TD control OFF delay when all compressors are off. This feature can be disabled with an Enable/Disable setpoint or when the discharge pressure is above a configurable setpoint.
RJ-11 to male RJ-11 cable. NOTE: The 9V battery and 9-12V DC adapter connection are not used on this HHT model (P/N 814-3110). 1 troller from the input boards is checked against current stored setpoints. If differences in the received input data and the setpoint information are detected, a signal is either sent to the proper 8RO relay, or an existing signal is discontinued.
2.2.6 4AO Analog Output Board The 4AO Analog Output Board (P/N 815-3030) (Figure 2-15) is configured with four analog output connections that provide a variable voltage signal to any of four analog devices that may be controlled by a single E2. Two 4-20mA outputs are provided for channels 1 and 2. The 4-20mA outputs provide a variable current for applications that are either externally powered or that require power from the 4AO board.
2.3 Echelon Network Boards and Peripherals 2.3.1 2.3.2 The 8ROe (Discontinued) The 16AIe (Discontinued) Figure 2-19 - 8ROe Figure 2-18 - 16AIe The 16AIe (P/N 810-4000) is an Echelon-based input board similar in function to its I/O Network counterpart, the MultiFlex 16 (see Section 2.2.2). The 16AIe receives input signals through any of 16 two-wire connections. The board receives either digital or analog data from sensors wired to any of the 16 input connections located on the board.
2.3.3 EC-2s 2.3.4 CC-100 Case Controllers and CS-100 Case Circuit Controllers A CC-100 case control board is a “smart” board capable of controlling all functions for a single case, including lights, fans, defrost, anti-sweat, and suction side or liquid side valve control. CC-100s perform these functions independently from the E2 RX controllers, but it does rely on a parent E2 for logging, alarming, providing supplemental I/ O values, and coordinating defrost times among circuits.
2.3.5 TD3 Temperature Display 2.3.6 Facility Status Display (FSD) The TD3 is a digital display unit designed to show both case temperature and product temperature for a refrigerated store case or walk-in freezer. The TD3 mounts on the front of a case and connects to up to three input devices (a case temperature sensor, a product temperature probe, and either a defrost termination probe or thermostat).
3 Mounting This section gives mounting instructions and dimensions for all controllers and peripherals in the E2 system. 9.0" 3.1 Mounting the E2 The E2’s box body style is designed to be mounted against or inside a wall or panel. If mounted against a surface, the controller will be 3.75” off the mounting surface. If mounted inside a surface, the door and front section of the back panel will rest 2.0” off the mounting surface. See Figure 3-1, and Figure 3-2. 3.1.

3.1.4 Blank Face for the MultiFlex, 16AI, 8RO, and the 8DO. Blank face control is designed to be used in a system with more than one E2. It has no screen or keyboard and is logged into remotely from another E2 on the Echelon network. The green General Status LED transmits status information to the user. See Table 2-3 on page 2-3 for more information on main board (CPU) status LEDs. Blank face mounting dimensions are identical to the standard and recessed mount boxes. See Figure 3-3 and Figure 3-4. 3.
3.2.2 Boards Without Enclosures (Snap Track) 16AI, 8RO, 8DO, and Gateway boards not supplied with an enclosure are supplied with a snap-track for easy installation. The insulation sheet and I/O board must be removed from the track before the track is mounted. The snap-track is mounted using the 0.1875” mounting slots. Figure 3-10 shows this installation procedure. Figure 3-9 provides mounting dimensions for the MultiFlex, 16AI, 8RO, and the 8DO boards. Figure 3-11 provides mounting dimensions for the 4AO.

Figure 3-15 shows the mounting dimensions of the TD3. Generally, the case controller will be mounted within the raceway or on top of the case. If a controller must be replaced or installed in the field, it should be located based on the specific design of the case. 8.05" O 0.18“ TYP 2 PLACES 0.25" 2.00" 3.
3.4.1 Two-Channel and FourChannel Repeaters 3.4.1.3 Mounting the Four-Channel Repeater 3.4.1.1 The four-channel repeater (P/N 638-4830) serves the same basic function as the two-channel repeater: boosting signal strength. However, the four-channel repeater is also useful as a means of connecting the E2 to its associated devices using more than one daisy chain.
3.5 Sensors and Transducers 3.5.1 Pressure Transducers Emerson Retail Solutions transducers convert pressure readings to proportional electrical signals between 0.5 and 4.5 volts. The transducer is designed with a 1/8-inch male FPT fitting for connection to a standard access fitting. If the fitting is configured with a Schrader valve, this fitting will have to be removed and replaced with a 1/8-inch female fitting.
3.5.4 Insertion Temperature Probe 3.5.4.1 Location typical sensor applications and the sensor or probe most suited for that purpose. Application Sensor Type The 12-inch insertion temperature probe may be used to monitor temperature in either the supply or return air ducts of the AHU or RTU. Condenser Outlet (Drop Leg) High Temperature Bullet 3.5.4.
3.5.7 Product Temperature Probes The product temperature probe is designed to be used alongside food products in a refrigeration case or freezer. The product probe uses a thermistor type temperature sensor in a sealed, cylindrical container (approximately 16 oz.). A magnet is contained at the bottom the probe’s enclosure to allow easy attachment to a side or bottom of a refrigeration case. 3.5.8 Humidity Sensors and Humidistats 3.5.8.
3.5.9 Dewpoint Probe 3.5.9.1 Location The Dewpoint Probe (P/N 203-1902) should be located 4 to 6 feet from the floor with the probe pointing up. It is recommended that the Dewpoint Probe be mounted in an area where it will be exposed only to minimal amounts of dust. 3.5.9.2 Mounting Mount the probe using the standard switch cover supplied with the unit as shown in Figure 3-26. Figure 3-24 - Outdoor RH Sensor - Exploded View 3.5.8.
3.5.11 Liquid Level Sensors Emerson Retail Solutions probe type liquid level sensor (P/N 207-1000 – discontinued) is usually installed by the refrigeration and equipment manufacturer. If a replacement sensor must be installed in the field, refer to the instructions supplied with the device, or consult the equipment manufacturer. 3.5.

6.1.5 Network Noise Minimization Site environments will frequently have numerous sources of high EMI, or “noise,” that must be accounted for when routing RS485 network cable. Although the cable is shielded against noise, the installer must follow best practices for minimizing network noise.
Dip switch 8 controls the baud rate at which the Gateway communicates with the other devices on the Receiver Bus Network. This baud rate may only be set to either 9600 baud (switch DOWN) or 19200 baud (switch UP). All Gateways and receivers on the Receiver Bus Network must have the same baud rate dip switch setting. It is recommended you use 9600 baud as the Receiver Bus Network baud rate. three jumpers set to the DOWN or NO position.
Emerson Retail Solutions supplies a wide variety of 24VAC transformers with varying sizes and either with or without center taps. Table 6-2 shows the transformer sizes and whether they are center-tapped or non-center-tapped. Xformer P/N VA Rating Table 6-3 lists each board, the board’s rating, and whether or not the board must use center-tapped power.
Use these formulas to determine if the wire gauge you are using fits within specification: 14 AWG: Feet = 1920/VA 18 AWG: Feet = 739/VA 6.3 MODBUS E2 controllers version 2.30F01 or greater may select MODBUS as a network type.

8 Echelon Network and Hardware Setup 8.1 Overview Echelon is an optional, two-conductor network that interconnects E2s and other associated devices, such as CC-100 case controllers, TD3 temperature displays, and ESR8 evaporator stepper regulator boards. All Echelon devices are wired together using the daisy-chain method of network structuring.
multiple routers can be used to extend the network indefinitely. More information about routers and how they are used in a daisy-chain Echelon Network can be found in the Router and Repeater Installation Guide (P/N 026-1605). RECOMMENDED E2 E2 8.4 UNBROKEN CHAIN E226513125rev Device Termination In a daisy-chain configuration, both ends of the network segment must be terminated. Terminate the E2 by setting jumper J2 to the UP position, as shown in Figure 8-3.
8.4.1 Using a Termination Block (P/N 535-2715) to Terminate a Daisy Chain a maximum of 63 more nodes. Some Echelon Network devices, notably TD3s, have no on-board means of terminating. For some other devices, it is inconvenient to use the jumpers supplied for termination (the CC-100/CS-100 case controllers, for example, require the enclosure to be removed to set the jumper). Refer to the Router and Repeater Installation Guide (P/N 026-1605), for information about router and repeater placement.

cycled ON or OFF. Unlike the Suction Group application, which uses a PID percentage to determine how many stages to turn ON or OFF, the Enhanced Suction Group keeps historical data of the effects each compressor stage has on the suction pressure or temperature, and analyzes that data to determine which stages to cycle. The Enhanced Suction Group application is designed to balance tight control of suction pressure with economic management of compressor cycling to reduce power usage and compressor wear. 11.

11.3.1 Refrigeration Control 11.3.2.1 A Standard Circuit application may apply one of four different control methods to a case circuit: the Temperature Monitor method, the Temperature Control method, and the Line Up(ESR)/Defrost method, and the Lineup(MFESR)/Defrost method. The defrost cycle for a Standard Circuit application consists of three steps. 11.3.1.1 11.3.1.2 Pump Down (Elec & Hot Gas only) - The defrost cycle begins with this step immediately after the refrigeration solenoid is turned OFF.
Any user-defined Pump Down and Run-Off times will be observed as normal. Electric Defrost Electric defrost uses electric heaters to defrost the evaporator coil. During electric defrost, the application will turn the Defrost output ON to activate the heaters connected to the output. Any user-defined Pump Down and Run-Off times will be observed as normal. 11.3.2.3 Defrost Termination Both the start and the end times of a defrost cycle are determined by the user.
11.3.3.2 Door Switches Walk-In Box freezers are often equipped with door switches that disable the evaporators when the door is open. The E2 is capable of reading a digital door switch input and controlling the freezer appropriately. When a door switch opens, the E2 will shut off the refrigeration solenoid and the fans (if active) and turn the lights ON. 11.3.4 Fan Control 11.3.

11.5.1 Possible Data Errors 11.5.2.1 For point log groups, regardless of the resolution, the following applies when errors occur in log data: Clipping occurs whenever the conversion process results in a sample value that falls outside the range of the selected log resolution. For example, converting a value of 750 PSI to low resolution would result in a compressed sample value of 609 PSI (refer to Appendix E: Compressed Point Log Sample Limits and Precision Tab).
matically. When you first create an application in the E2, you can tell which inputs and outputs belong to the Base Log Group: an “L” will be displayed at the right-hand side of their definitions. The “L” is a marker that signifies that the input or output is currently part of a logging group (either the Base Log Group or another group as assigned by the user). If there is no “L” beside the definition, the value is not part of a logging group and therefore will not be logged. 11.5.
11.5.5 Logging Group Status Screen 2. Press 8. Application Logs/Graphs to bring up the APPLICATION SPECIFIC LOGS AND GRAPHS menu. From the Logging Group Summary screen, you can also access the Status screen for any logging group in the list by highlighting the desired group and pressing Enter: 3. Press 1. Logging Group Report.
11.5.6.3 System Log Report The System Log report provides a summary of all logged points for all applications in the system and a complete list of logged points for all applications in the system. Note that depending on the size of the configuration and the number of points logged, this may take a few seconds. To display the System Log Report: 1. Press for the Main Menu. 2. Press for System Configuration. 3. Press Logging Setup. 4. Press Display Logged Points.
11.6.4 Fan Control 11.6.4.3 The E2 BX can control three different types of AHU fans. However, only one fan can be controlled per AHU. The fan types include: single-speed, two-speed, and variable-speed. Controls for all fans are similar in that they operate in either of three modes: Variable-speed fans may operate at any percentage of its maximum speed. The method AHU Control uses to determine the speed percentage is dependent on whether the heat and cool outputs are staged or modulating.
11.6.5 Economizer Control Economizer dampers on AHUs are used to bring outside air into the building for use in cooling. When temperature and humidity conditions are favorable, the economization dampers are opened, and outside air is allowed to flow into the AHU. Economization is generally used by the AHU just as a cool stage would be in Temperature Control; if cooling is needed, and conditions are favorable for economization, the dampers will open and economization will begin.
11.6.9 Curtailment Some power companies offer curtailment programs that allow participating stores to disable user-defined loads during peak power times in return for discounts on utility rates. If you are participating in a curtailment program, the power company will supply you with a digital curtailment device that must be wired to an input on the RS485 I/O Network. To set up curtailment in the system software, you must designate which specific heating and cooling stages will be subject to curtailment.
11.6.11 Separate Setpoints Inputs The Separate Setpoints strategy for AHU allows a Cut In/Cut Out setpoint to be set up for each heat and cool stage instead of just one cool and one heat setpoint set up for each stage (Normal strategy). Dehumidification control can be performed while controlling with separate setpoints. 11.6.

Stages you want OFF should be set as N.O. Single-Speed Fans see note see note If one or more heat or cool stages will be ON, wire fan N.C. so it will be active during controller off-line times. Otherwise, wire N.O.
11.7.3 Applications That May Be Connected To Zones There are three different HVAC applications that may be associated with a Zone application: a MultiFlex RTU application, a MultiFlex RCB application, and an AHU application. The MultiFlex RTU and RCB applications interface with the MultiFlex RTU and RCB I/O Network boards that control rooftop units. AHU applications use input and output points on the I/O Network to control air handling units. 11.7.3.
11.7.3.3 AHUs Zone’s HVAC applications. An AHU controls all aspects of an air handling unit, including up to eight stages of auxiliary or reclaim heat, six cooling stages, dehumidification, analog or digital economization, and support for single-, two-, or variablespeed fans. Normally, since AHUs are designed to cover a wide area of space, AHU Control applications operate on their own and are not associated with Zone applications (they are large enough to be “zones” within themselves).
enthalpy of the outdoor air is calculated and compared to the enthalpy of the indoor air. If the outdoor air enthalpy is less than the indoor air enthalpy, economization is enabled. Otherwise, economization is disabled. You may choose a different method for use in summer and winter months. Also, an alternate method may be specified that will be used as a fail-safe when the primary method is not available (due to sensor failure, etc.). 11.7.
and cooling several minutes before the Zone application is scheduled to change occupancy states, and prepares the area for the upcoming change in setpoints. As a result, when the occupancy state changes, the temperature will be comfortably within the range of the new setpoint. cooling is active. This is used to determine pre-stop durations for both heating and cooling AHUs.
11.7.13 Losing Contact With Zone Applications When a MultiFlex RTU or AHU loses contact with the Zone application to which it was assigned, it is forced to operate in Stand-Alone Mode. Each of the different applications have different stand-alone capabilities. 11.7.14 Stand-Alone MultiFlex RTUs The MultiFlex RTU uses its own occupied and unoccupied heating and cooling setpoints when it operates in Stand-Alone Mode.
11.9 MultiFlex PAK Board The PAK is a distributed pack (rack) controller that controls compressors and condenser fans. The PAK can control up to 8 compressor groups containing up to 16 compressors. The compressor control strategy is Fixed Steps with setpoint/deadband using ON and OFF delays. Up to 20 Fixed Steps can be configured. setpoints, and overrides the schedule as the real-time lighting conditions warrant.

Both OFF strategy, except only the light level state must turn OFF in order to turn the output from ON to OFF. • LLEV ON/Both OFF - Like the Both ON/ Both OFF strategy, except only the light level state must turn ON in order to turn the output from OFF to ON. • Both ON/Any OFF - Like the Both ON/Both OFF strategy, except any of the two states that turn from ON to OFF will result in the output turning OFF.
11.10.5.2 Offset Solar Control The Offset Solar Control cell of the Lighting Schedule application uses the Sunrise Offset and Sunset Offset parameters to determine how many minutes before or after sunrise the sun is considered to be risen, or how many minutes before or after sunset the sun is considered to be set. The resulting offset for sunrise and sunset is used by Lighting Control in its logical equations for the Solar state.
proof latch time. 11.10.9 Output Light Dimming The dimming feature allows the lighting output to be varied based on a light level sensor. Dimming capability can work with both Standard Control and Alternate Control configuration. For setup, the user can: • Specify the light levels for the minimum and maximum light output. • Specify the ramp speed that the indoor lighting output changes. 11.
integral) of the demand window. The integral error represents how far below or above the setpoint the input has been for the entire demand window. Under non-demand conditions, the integral error will be below zero, since the average KW or watt-hour value will be below the setpoint. The current value of the integral error and the current value of the KW input are what determine when the Demand Control application will begin load shedding. 11.11.3 Load Shedding 11.11.3.
rooms. 2. Rotational Shed The Rotational Shed levels are shed in sequence only if all defined First Shed levels have already been shed and the Demand Control application needs more shedding to lower demand. Unlike the First Shed priority levels, Rotational Shed levels do not always begin shedding by activating level #1. Instead, it shares the burden of being the first to activate among all the Rotational Shed levels.
11.11.6 How Demand Control Uses Load Shedding Demand Control uses three parameters to perform load shedding: the current KW input value, the current integral error (described in Section 11.11.2, Demand Monitoring), and the active KW setpoint. The active setpoint is chosen from four different setpoint values depending on the season (summer or winter) and occupancy (occupied or unoccupied). The Demand Control application is programmed with three different “modes” of operation.
loads. 11.11.6.1 Power Monitoring Input The Input Type Selection parameter defines the way the Power Monitoring input (INPUT under the Inputs tab in application Setup) will be used. The parameter can be set to: KW Analog, or Pulse KWH. 11.12.3 Cut In/Cut Out Setpoint Control Cut In/Cut Out setpoints work differently depending upon whether the Cut In/Cut Out setpoint is higher.
11.12.4 Digital Sensor Control The Digital Sensor Control module performs three basic functions: • LOGICAL COMBINATION: Up to four inputs may be combined using standard logical combination methods (such as AND, OR, XOR, etc.) The result is the command output value, which can be used to operate a relay. • BYPASS: The command output may be configured to be bypassed to a fixed value by a switch or button press.
change drastically. The filtered PID percentage is sent to the final control cell, the Override cell. stages and/or with pulse width modulation. Sequencer - The Sequencer cell will use the percentage to activate an equivalent percentage of its defined stage outputs. The Sequencer supports up to eight cells, and also provides for minimum on/off times and first-on/ last-off sequencing. Step 5: Override - Once the PID percentage is figured, the Override cell provides for overrides of the PID percentage.
assume this application will not use occupancy-based setpoints, and will use the occupied setpoint only (no switching). Note the Select cell does not have any on-board schedule function to determine for itself whether the building is occupied or unoccupied. It relies solely on the digital state of the Occupancy input. If you wish to follow a schedule for occupancy, this input must be tied to the output of a Time Schedule application. 11.13.2.
If desired, delays may be specified for stage activation and deactivation. Also, the definitions of OFF and ON may be redefined as either ON, OFF, or NONE. 11.13.3.2 The PWM Cell The PWM cell converts the control output percentage into a periodic ON pulse. A “pulse” in this cell is a constant period of time that consists of one ON event and one OFF event. The PWM cell takes the PID percentage and turns the output ON for an equivalent percentage of the total pulse period.
11.14.1.3 Temporary Schedule Events 11.15 Power Monitoring Each schedule may also be given up to three pairs of temporary schedule events. These events start and end at specific days and times and do not continue past those dates (in other words, temporary events cannot be made to occur weekly or annually). A Power Monitoring application is used primarily for monitoring, recording, and to a lesser degree controlling KW usage in a building. 11.14.1.
overall system. The SHED OUT output remains ON until the KW usage falls below the demand setpoint. In short, the purpose of Shed Mode is to get the total KW usage below the demand setpoint as soon as possible. NOTE: If you do not wish to use load shedding for your building, simply do not connect anything to the SHED OUT output.
power monitoring inputs will appear under the Inputs tab of the application. All inputs must be connected to board and points set up with Engineering Units of Amps. 11.16 Anti-Sweat Setup An anti-sweat application controls one anti-sweat zone. An anti-sweat zone is defined as one or more antisweat heaters that use the same dewpoint (or RH and temperature) sensors and the same control setpoints.
11.17.2 Unoccupied Hysteresis HYSTERESIS OUTPUT 100% TEMPERATURE 0% HEATING SET POINT COOLING SET POINT 26512035 Figure 11-26 - Unoccupied Hysteresis Mode 11.17.3 Optimum Start/Stop (OSS) NOTE: OSS applies only to Heat/Cools that use a time schedule to change occupancy states. Overrides initiated by the digital OCC STATE input will not initiate pre-starts or prestops. Optimum Start/Stop (OSS) is a feature that works alongside the Heat/Cool’s occupied and unoccupied temperature control modes.
As the value of the reset sensor varies within the minimum and maximum range, an equivalent portion of the maximum setpoint adjustment will be added or subtracted from the heating or cooling setpoint. When the reset sensor value is directly in between the minimum and maximum range values, nothing will be added or subtracted from the setpoint. Between the halfway point and the minimum value, part of the setpoint adjustment will be subtracted from the setpoint.
must be used. A Multiple Input cell is a simple application that reads data values from its inputs, combines them using a userdefined combination strategy, and sends the combined value to the desired application input. A common application for this is in HVAC control, where a single heating control value might come from an average of a number of temperature sensors throughout the building.
drop leg temperature rises above this setpoint, the condenser fans are cycled ON regardless of the value of the TD. The Drop Leg Offset setpoint is an adjustment entered, if needed, after measuring liquid subcooling during operation of an individual condensing unit. The TD setpoint is the optimal difference between the refrigerant drop leg temperature and the ambient (plenum) temperature. When the TD (i.e.
total accumulation, and the last accumulated total information can be viewed. The current output shows the rate of consumption of the quantity represented by pulses. Average output shows the average rate value accumulated over the period set in the Average Window parameter. The High Limit Trip output will turn on if the total accumulation exceeds a userspecified high limit. Total accumulation shows the total accumulated value since the last reset.
11.21.2.1 Cycle Control Types 11.21.4 Zone Inhibit By default, Timed cycles are always used unless the user has configured a flow sensor (optional). If a flow sensor is configured, a control type parameter will become visible where the user can select either a Timed or Volume cycle control type. Inhibiting sensors enable a zone to terminate irrigation early when enough water has been dispensed for the current cycle, or completely removes a zone from the cycle.
When a zone is bypassed to ON, the main water valve will be turned ON immediately. 11.21.5.1 Bypass Failsafe While each zone is bypassed to ON, a timer is checked. If time has elapsed equal to or greater than the zone’s cycle duration parameter, the bypass input will be ignored and the zone will return to normal operation. For a zone in Bypass Failsafe, its bypass input must be set to OFF or NONE to reset the Bypass Failsafe and to use the bypass input again. 11.21.6 Flow Sensor-Related Tests 11.21.6.

If for any reason the algorithm thinks that the high speed and the low speed should both be ON, the highspeed fan should be turned ON only. 11.23 Modular Chiller Control (MCC) Proper fan speed should be set when there are no heating or cooling stages ON, and the Fan Always On Setpoint is enabled. 11.21.
Figure 11-1 - Compact Chiller System 11.23.2 Learning Mode 11.23.4 Compressor Control When an MCC application runs for the first time, it undergoes a "Learning Mode" period to collect data on the chiller stages. During Learning Mode, the MCC will control the chilled water temperature, but it will purposely cycle the chiller stages in different combinations to measure the effect they have on the temperature input value.
11.23.4.1 Digital Scroll Compressor MCC can also utilize a single Digital Scroll Compressor. The assumption is that one of the Compressor Control Modules in the system may have a digital scroll instead of a standard scroll compressor installed. The Digital Scroll Compressor may not be the same size as the fixed scroll compressors.
11.25 Refrigerant Monitoring System (RMS) The RMS enables the E2 ability to measure the refrigerant used to add, remove and repair an asset that has a refrigerant charge. RMS is available for E2 versions 3.01 and above. The RMS comes with two components that are installed together, the RMS asset and the RMS scale. A total of 99 RMS applications can be supported by the E2. The RMS is a licensed application. For licensing instructions, refer to the software licensing section (see Section 10.

Appendix D: PID Control Introduction to PID Control PID Control is a specialized method of closed-loop control that strives to maintain equality between an input value and a user-defined setpoint by operating a device or a number of devices at somewhere between 0% and 100% of full capacity. PID Control works by making adjustments to the output at a constant rate called the update rate (usually 2-6 seconds).
Throttling Range on page D-1. . THROTTLING RANGE OUTPUT AT SETPOINT (shown here as 50%) If Proportional Mode is functioning incorrectly in your system, it may be more appropriate for you to change the Throttling Range value to a more appropriate value. Kp is designed as a fine-tuning constant (for example, it might be used to speed up reaction slightly by setting it to 1.04, or to slow down reaction by setting it to 0.98).
TEMPERATURE TEMPERATURE S E T P O I N S T E T P O I N T TIME TIME “P” + “I” MODES “P” MODE ONLY Figure D-2 - Comparison of “P” Mode vs. “P” + “I” Mode Saturation Once the input value has wandered outside Proportional Mode’s throttling range, the output percentage will be at 0% (if below the Throttling Range) or at 100% (if above the Throttling Range).
sate for error. the case temperature equal to the temperature setpoint. To reduce this lag time, Derivative Mode is used. Derivative Mode constantly analyzes the rate of change of the error, makes a prediction about what the future error will be, and makes an adjustment to the output in an attempt to reduce the rate of change in the error. Condenser Control and HVAC Control seek only to keep pressure or temperature values below or above their setpoints.
THROTTLING RANGE OUTPUT AT SETPOINT (shown here as 50%) point, the output percentage is dropped from 50% (it is assumed this will result in the input rising back to the setpoint). Likewise, when the input is higher than the setpoint, the output percentage is raised. For Condenser Control PID, no reaction is made to an input that is lower than the setpoint, since the output percentage is already 0%.
are 20% and 100% respectively, the output percentage will never be below 20%, even if the P, I, and D Mode adjustments call for the output to be below 20%. The output will remain in saturation at 20% until a higher output percentage is called for. In short, PID works as it normally does, except the output never goes below Output at Minimum or above Output at Maximum.

Appendix F: Troubleshooting The chart below describes symptoms and solutions if troubleshooting the system or equipment is needed. For further information, contact Emerson Retail Solutions Service at 1-800-829-2724. SYMPTOM I/O Network Problems POSSIBLE PROBLEM SOLUTION I/O board not getting power. Check I/O board power--is the green STATUS light on? If not, check power wiring connections, and use a multimeter to verify the board is getting 24VAC. Reset power to board.
SYMPTOM Echelon Network Problems F-2 • E2 RX/BX/CX I&O Manual POSSIBLE PROBLEM SOLUTION Faulty wiring. Check connections. Are wires broken or loose? Check network polarity (positive to positive/ negative to negative). Check for wire damage. Termination jumpers are set incorrectly. Check for proper setting of terminating resistance jumpers. Network segment should be terminated on the two endpoints of the daisy chain and unterminated everywhere else. Refer to Section 8.4, Device Termination.
SYMPTOM Compressor will not Operate POSSIBLE PROBLEM SOLUTION Compressor is not programmed properly. Verify that E2 was programmed for correct number of compressor stages. Highlight the General tab (C1) in the Suction Group Setup screen. Is the correct number of stages in the “Number of Stages” field? Compressor types are set up incorrectly. Make sure that compressor stages were properly set up as VS (variable speed), C (compressor), or U (unloader). Compressor programmed with incorrect rating.
SYMPTOM Compressor will not Operate (Cont.) F-4 • E2 RX/BX/CX I&O Manual POSSIBLE PROBLEM SOLUTION 8RO fail-safes are not wired correctly. Verify fail-safe wiring on 8RO board for N.O./N.C. positions. One wire of the two-wire connection should always be connected to the middle terminal. The second wire must be either connected to the N.C. terminal (if you want the relay to be closed (ON) during power failure) or the N.O. terminal (if you want the relay to be open (OFF) during power failure.
SYMPTOM Problems with Condenser POSSIBLE PROBLEM SOLUTION Condenser will not operate. Verify that E2 is programmed with proper number of fans. 1. Highlight the General tab (C1) in the Condenser Setup screen. 2. Is the correct number of fans in the Number of Fans field? Incorrect board and point settings. Confirm proper board and point settings: Go to the Inputs tab (C3) in the Condenser Setup screen to check PRES CRTL IN and DISCH TRIP IN. Fail-Safe wiring on 8RO is incorrect.
SYMPTOM Problems with Cases Problems with Global Actions F-6 • E2 RX/BX/CX I&O Manual POSSIBLE PROBLEM SOLUTION Case will not go into hot gas or cool gas defrost. Check Group LLSV in Suction Group setup: 1. Go to the Outputs tab (C5) on the Suction Groups Setup screen and check GROUP LLSV. 2. Verify that the case(s) is assigned to the correct group. Case will not terminate out of defrost mode. 1. Verify the termination type (Term Type) in the Defrost tab (C4) in the Standard Circuits Setup screen.
SYMPTOM Problems with Temp Sensor or Pressure Transducer Displaying Proper Value POSSIBLE PROBLEM SOLUTION 16AI input dip switches are set improperly. The 16 dip switches on the 16AI board correspond to each of the inputs: Dip Switches Up = Temperature Sensor Dip Switches Down = Pressure Transducer Incorrect board and point address. Set proper board and point settings for both input and output: Go to the Inputs tab in the application’s Setup screen and check Board and Point. Incorrect sensor type.
SYMPTOM Dehumidification Problems Lighting Control Problems POSSIBLE PROBLEM SOLUTION Number of stages are not set up or set up incorrectly. From the Home screen, press (AHU), (SETUP). Move cursor to C9 (Dehum) to check Dehum Stages. Dehumidifier source not set up. From the same screen, verify what the sensor source is. Temperature setting for DEHUM OCC or DEHUM UOC is set too high. From the same screen, check the minimum temperature setting. Lights will not come on.
