If the system asserts V IL on the WP# pin, the device disables program and erase functions inthe first or last sector independent of whether those sectors were protected or unprotected; ifthe system asserts V IH on the WP# pin, the device reverts to whether the first or last sector waspreviously protected or unprotected. If ACC = V HH, all sectors will be unprotected.2. Please refer to “Sector Group Protection & Unprotection”, Flowchart 6a and Flowchart 6b.3. D IN or D OUT as required by command sequence, data polling, or sector protect algorithm.Read ModeThe device is automatically set to reading array data after device power-up or hardware reset. No commands are required to retrieve data. The device is also ready to read array data after completing an Embedded Program or Embedded Erase algorithmAfter the device accepts an Sector Erase Suspend command, the device enters the Sector Erase Suspend mode. The system can read array data using the standard read timings, except that if it reads at an address within erase-suspended sectors, the device outputs status data. After completing a programming operation in the Sector Erase Suspend mode, the system may once again read arraydata with the same exception. See “Sector Erase Suspend/Resume Commands” for more additional information.The system must issue the reset command to re-enable the device for reading array data if DQ5 goes high or while in the autoselect mode. See the “Reset Command” for additional details.Output Disable ModeWhen the OE# pin is at a logic high level (V IH), the output from the device is disabled. The output pins are placed in a high impedance state.Standby ModeThe device has a CMOS-compatible standby mode, which reduces the c urrent to < 1µA (typical). It is placed in CMOS-compatible standby when the CE# pin is at V CC± 0.5. RESET# and BYTE# pin must also be at CMOS input levels. The device also has a TTL-compatible standby mode, which reduces the maximum V CC c urrent to < 1mA. It is placed in TTL-compatible standby when the CE# pin is at V IH. When in standby modes, the outputs are in a high-impedance state independent of the OE# input.Automatic Sleep ModeThe device has an automatic sleep mode, which minimizes power consumption. The devices will enter this mode automatically when the states of address bus remain stable for t acc + 30ns. ICC4 in the DC Characteristics table shows the current specification. With standard access times, the device will output new data when addresses change.Writing Command SequencesTo write a command or command sequence to program data to the device or erase data, the system has to drive WE# and CE# to V IL, and OE# to V IH.The device has an Unlock Bypass mode to facilitate faster programming. Once the device enters the Unlock Bypass mode, only two write cycles are required to program a word, instead of four.The system can also read the autoselect codes by entering the autoselect mode, which need the autoselect command sequence to be written. Please refer to the “Command Definitions” for all the available commands.Autoselect Identification ModeThe autoselect mode provides manufacturer and device identification, and sector protection verification, through identifier codes output on DQ15–DQ0. This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. However, the autoselect codes can also be accessed in-system through the command register.When using programming equipment, the autoselect mode requires V ID(10.5 V to 11.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in Autoselect Codes table. In addition, when verifying sector group protection, the sector group address must appear on the appropriate highest order address bits. Refer to the corresponding Sector Address Tables. The “Command Definitions” table shows the remaining address bits that are don’t-care. When all necessary bits have been set as required, the programming equipment may then read the corresponding identifier code on DQ15–DQ0.To access the autoselect codes in-system; the host system can issue the autoselect command via the command register, as shown in the Command Definitions table. This method does not require V ID. See “Command Definitions” for details on using the autoselect mode. Note that a Reset command is required to return to read mode when the device is in the autoselect mode.TABLE 4. Autoselect Codes (Using High Voltage, V ID )L=logic low= V IL , H=Logic High= V IH , V ID =11 ± 0.5V, X=Don’t Care (either L or H, but not floating!), SA=Sector AddressesNote:1. A8=H is recommended for Manufacturing ID check. If a manufacturing ID is read with A8=L, the chip will output a configuration code 7Fh.2. A9 = V ID is for HV A9 Autoselect mode only. A9 must be ≤ Vcc (CMOS logic level) for Command AutoselectMode.ACC: Accelerated Program OperationThe device offers accelerated program operation which enables the programming in higher speed. When ACC is raised to V HH , the memory automatically enters the Unlock Bypass mode (please refer to “Command Definitions”), temporarily unprotects every protected sector groups , and reduces the time required for program operation. The system would use a two-cycle program command sequence as required by the Unlock Bypass mode. When ACC returns to V IH or V IL , normal operation resumes. The transitions from V IH or V IL to V HH and from V HH to V IH or V IL must be slower than t VHH , see Figure 5.Note that the ACC pin must not be left floating or unconnected. In addition, ACC pin must not be at V HH for operations other than accelerated program. It could cause the device to be damaged. Never raise this pin to V HH from any mode except Read mode; otherwise the memory may be left in an indeterminate state.A 0.1µF capacitor should be connected between the ACC pin and the V SS Ground pin to decouple the current surges from the power supply. The PCB track widths must be sufficient to carry the currents required during Unlock Bypass Program.RESET#: Hardware ResetWhen RESET# is driven low for t RP , all output pins are tristates. All commands written in the internal state machine are reset to reading array data.Please refer to timing diagram for RESET# pin in “AC Characteristics”.Sector Group Protection & UnprotectionThe hardware sector group protection feature disables both program and erase operations in any sector group. The hardware chip unprotection feature re-enables both program and erase operations in previouslyDescription CE# OE# WE# A21toA15 A14 to A10A92A8A7A6A5 to A2A1 A0 DQ15 to DQ0H1XX1Ch Manufacturer ID: Eon L L H X X V IDLX L XL LXX7FhAutoselect Device ID L L H X X V IDX X L X L H 22D7h Sector Protection VerificationL L H SA X V IDX X L X H LXX01h(Protected)XX00h(Unprotected)protected sector group. A sector group consists of four adjacent sectors that would be protected at the same time. Please see Table 2 which show the organization of sector groups.There are two methods to enable this hardware protection circuitry. The first one requires only that the RESET# pin be at V ID and then standard microprocessor timings can be used to enable or disable this feature. See Flowchart 6a and 6b for the algorithm and Figure 11 for the timings.When doing Sector Group Unprotect, all the unprotected sector groups must be protected prior to any unprotect write cycle.The second method is for programming equipment. This method requires V ID to be applied to both OE# and A9 pins and non-standard microprocessor timings are used. This method is described in a separate document, the Datasheet Supplement of EN29LV641H/L / EN29LV640U, which can be obtained by contacting a representative of Eon Silicon Solution, Inc.WP#: Write ProtectThe Write Protect function provides a hardware method to protect the first or last sector against erase and program without using V ID.When WP# is Low, the device protects the first or last sector regardless of whether these sectors were previously protected or unprotected using the method described in “Sector Group Protection & Unprotection”, Program and Erase operations in these sectors are ignored.When WP# is High, the device reverts to the previous protection status of the first or last sector. Program and Erase operations can now modify the data in those sectors unless the sector is protected using Sector Group Protection.Note that the WP# pin must not be left floating or unconnected.Temporary Sector Group UnprotectThis feature allows temporary unprotection of previously protected sector groups to change data while in-system. The Temporary Sector Group Unprotect mode is activated by setting the RESET# pin to V I D. During this mode, formerly protected sector groups can be programmed or erased by simply selecting the sector group addresses. Once V I D is removed from the RESET# pin, all the previously protected sector groups are protected again. See accompanying flowchart and timing diagrams in Figure 10 for more details.StartReset#=V ID(note 1) Perform Erase or ProgramOperationsRESET#=V IH Temporary Sector Group Unprotect Completed (note 2)Notes:1. All protected sector groups are unprotected. (If WP#=V IL, the first or last sector will remain protected.)2. Previously protected sector groups are protected again.COMMON FLASH INTERFACE (CFI)The common flash interface (CFI) specification outlines device and host systems software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility.This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h, any time the device is ready to read array data.The system can read CFI information at the addresses given in Tables 5-8.The upper address bits (A7–MSB) must be all zeros. To terminate reading CFI data, the system must write the reset command.The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode and the system can read CFI data at the addresses given in Tables 5–8. The system must write the reset command to return the device to the autoselect mode.Table 5.

Additionally, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by false system level signals during Vcc power up and power down transitions, or from system noise.Low V CC Write InhibitWhen V CC is less than V LKO, the device does not accept any write cycles. This protects data during V CC power up and power down. The command register and all internal program/erase circuits are disabled, and the device resets. Subsequent writes are ignored until V CC is greater than V LKO. The system must provide the proper signals to the control pins to prevent unintentional writes when V CC is greater than V LKO.Write Pulse “Glitch” protectionNoise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle.Logical InhibitWrite cycles are inhibited by holding any one of OE# = V IL, CE# = V IH, or WE# = V IH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a logical one. If CE#, WE#, and OE# are all logical zero (not recommended usage), it will be considered a read.Power-up Write InhibitDuring power-up, the device automatically resets to READ mode and locks out write cycles. Even with CE# = V IL, WE#= V IL and OE# = V IH, the device will not accept commands on the rising edge of WE#.COMMAND DEFINITIONSThe operations of the device are selected by one or more commands written into the command register. Commands are made up of data sequences written at specific addresses via the command register. The sequences for the specified operation are defined in the Command Definitions table (Table 9). Incorrect addresses, incorrect data values or improper sequences will reset the device to Read Mode.Table 9.

When the battery is damaged or cannot be changed, the data in the program and latched area will be lost. If the user needs to permanently save the data in he latched area in the program and device D, please refer to “Flash ROM permanently saved and recover mechanism ” as stated below. Permanently saved mechanism:The user can use ELCSoft (Options -> ELC<=>Flash) to indicate whether to permanently store the data in the latched area in the program (including password) and device D in Flash ROM memory (new indicated data will replace all data previously saved in the memory). Recover mechanism:If the rechargeable battery is in low voltage, resulting in the loss of data in the program, ELC will automatically restore he data in the latched area in the program and device D of Flash ROM into SRAM memory (M1176 = On) next time when 24V DC is re-powered. The ERROR LED flashing will remind the user that if the recorded program is able to resume its execution, the user only needs to shut down and re-power the ELC once to restart its operation (RUN).3ELECTRICAL SPECIFICATIONSInput pointTypeCurrent Motion levelResponding timeDC (Sink or Source)24VDC 5mAX0~X7,X12~X13,X16~X17Off On Ї165VDCX10~X11,X14~X15Off On Ї18.5VDCX0~X17 On Off І8VDCApprox. 10 ms (can be adjusted within the range of 10 ~ 60 ms by D1020 and D1021)Output pointType Current Voltage Max. loadingRespondingtimeMechani-cal life Electrical life relay-R1.5A/1 point (5A/COM)250VAC,Ї30VDC75VA (inductive) 90 W (resistive)Approx. 10 ms2×107times (without load)1.5×105times (5A 30VDC) 5×105 times (3A 120VAC)3×104 times (5A 250VAC)transistor-TGeneral: 0.3A/1 point @40ºCHigh-speed: І1kHz, 0.3A/1 point @ 40ºC; ≥ 1kHz,30mA/1point@40 ºC30VDCMax. 10kHz for Y5, Y7, Y10 ~ Y13Off On 20us On Off 30usMax. 200kHz for Y0, Y1, Y2, Y3, Y4, Y6Off On 0.2us On Off 0.2us4MODEL NAME & I/O CONFIGURATION5INSTALLATION & WIRING5.1 Mounting & WiringThe ELC can be secured to a cabinet by using the DIN rail of 35mm in height and 75mm in depth. When mounting ELC to DIN rail, be sure to use he end bracket to stop any side-to-side movement of ELC and reduce the chance of wires being loose. A small retaining clip is at the bottom of ELC. To secure ELC to DIN rail, place the clip onto he rail and gently push it up. To remove it, pull the retaining clip down and gently remove ELC from DIN rail, as shown in figure 1.Please use M4 screw (see figure 2) according to the dimension of the product. Please install ELC in an enclosurewith sufficient space around it to allow heat dissipation (see figure 3).9053.270101109.4D > 50 mmFigure 1Figure 2 (Unit: mm)Figure 35.2 Wiring1. Use 22-16AWG (1.5mm) single or multiple core wire on I/O wiring terminals. Thespecification of the terminal is shown in the figure on the left. The ELC terminalscrews shall be tightened to 1.95 kg-cm (1.7 in-lbs).2. DO NOT place the I/O signal wires and power supply wire in the same wiring duct.3. Use 60/75 ºC copper wires only.DO NOT install ELC in an environment with:1. Dust, smoke, metallic debris, corrosive or flammable gas2. High temperature, humidity3. Direct shock and vibration5.3 Power Input WiringThe power input of ELC-PV series is DC. When operating ELC-PV series, please make sure that:1. The power is connected to the two terminals, 24VDC and 0V, and the range of power is 20.4VDC ~28.8VDC. If the power voltage is less than 20.4VDC, ELC will stop running, all outputs will go “Off” andERROR indicator will flash continuously.2. A power shutdown of less than 10 ms will not affect the operation of ELC. However, power shutdown timethat is too long or a drop of power voltage will stop the operation of ELC and all outputs will go “Off”. When the power supplied again, ELC will automatically return to its operation. (Please be aware of the latched auxiliary relays and registers inside ELC when programming.)DC power input5.4 Input point wiringThere are two types of DC inputs, SINK and SOURCE.5.5 Output point wiring5.6 Relay (R) contact circuit wiring5.7 Transistor (T) contact circuit wiring6 TRIAL RUN■Preparation1. Prior to applying power, please verify that the power lines and the input/output wiring are correct. And beadvised not to supply 110V AC or 220V AC into he I/O terminals, or it might short-circuit the wiring and would cause direct damage to the ELC.2. After using the peripheral devices to write the program into he ELC and that the ERROR LED of the ELCis not on, it means that the program in use is legitimate, and it is now waiting for the user to give the RUN command.3. Use ELC-HHP to execute the forced On/Off test of the output contact.■Operation & test1. If the ERROR indicator does not flash, you can use the RUN/STOP switch or a peripheral device(ELC-HHP or ELCSoft) to give a RUN instruction. The RUN indicator should be continuously on at thistime. That the RUN indicator does not flash indicates ELC has no program in it.2. When ELC is in operation, use ELC-HHP or ELCSoft to monitor the set value or temporarily saved valuein timer (T), counter (C), and register (D) and force On/Off of output contacts. That the ERROR indicator is on (not flashes) indicates that part of the program exceeds the preset time-out. In this case, you have to set the RUN/STOP switch as STOP first, check special register D1008 and obtain the location in theprogram where time-out takes place. Please refer to he WDT instruction to solve this problem.■Operation of ELC basic sequential instruc ions & application instruc ions1. The basic sequential instructions and application instructions of ELC-PV series are compatible with allELC series ELCs. See Eaton “ELC System Manual” for relevant information.2. All ELC series ELCs are compatible with ELC-HHP handheld programming panel, ELCSoft ladderdiagram for program editing and exclusive transmission cables to connect with ELC-PV for programtransmission, ELC control, program monitoring and so on.7 TROUBLESHOOTINGBased on the indicators on the front panel, please check the following for errors:☼POWER indicatorWhen ELC is powered, the POWER LED indicator on the front panel will be on (in green). If this indicator is not on or the ERROR indicator keeps flashing when ELC is powered indicates that the power supply +24V are insufficient or DC power supply 24V is overloaded. In this case, change another 24V DC power supply. If the indicator is still off at this time, your ELC is malfunctioned. Send your ELC back to your distributor for repair.☼RUN indicatorCheck your ELC status. When ELC is running, this indicator will be on. You can use ELC-HHP, the ladder diagram editing program or the switch on the panel to RUN or STOP ELC.☼ERROR indicatorIf you enter illegal program into ELC or use instructions or devices that exceed their range, this indicator will flash (approx. every 1 second). When this happens, you have to obtain the error code from D1004 and save the address where the error occurs in register D1137 (if the error is a general circuit error, the address of D1137 will be invalid). Find out the cause of the error, amend the program and resend the program to ELC. If you cannot connect to ELC and this indicator keeps flashing quickly (approx. every 0.2 second), it means that the 24VDC power voltage is insufficient. Please check if the 24V DC is overloaded.If the ERROR indicator is on, you have to check the special relay M1008. If M1008 is on indicates that the execution time of program loop exceeds the preset time-out (in D1000). In this case, turn the RUN/STOP switch to STOP, check the special register D1008 and obtain the location in the program where the time-out takes place. Please refer to the WDT instruction to solve this problem. After amending the program, you only need to resend the program to stop the indicator from flashing. If the indicator still keeps flashing at this time, switch off he power and check if there is any interference existing or conductive matter inside ELC.For details of error codes (in D1004, hex coding), see “ELC System Ma nual: Programming”.☼BAT.LOW indicatorThe rechargeable lithium-ion battery in ELC-PV is mainly used on the latched procedure and data storage.The lithium-ion battery has been fully charged in the factory and is able to retain the latched procedure and data storage for 12 months. If ELC-PV has not been powered and used for more than 12 months, the battery will be out of power upon normal consumption and the procedure and data will be lost.The lithium-ion battery has longer life span than ordinary battery; therefore there is no need to change battery very frequently. You can charge the battery at any time without having to worry about a decrease in chargeability.You can also recharge the battery even when there is still power in the battery.Please be aware of the date of manufacturing; the charged battery can sustain for 12 months from this date. If you find that the BAT.LOW indicator stays on after ELC is powered, the battery voltage is low and the battery is being charged. ELC-PV has to remain on for more than 24 hours to fully charge the battery. If the indicator turns from on to “flash” (every 1 second), it indicates that the battery cannot be charged anymore. Please correctly process your data in time and send the ELC back to Eaton for changing a new battery.Precision of calendar timer:At 0̓C/32̓F, less than –117 seconds error per month.At 25̓C/77̓F, less than 52 seconds error per month.At 55̓C/131̓F, less than –132 seconds error per month.☼Input indicatorOn/Off of input point is indicated by input indicator or monitored by ELC-HHP. When the action condition of the input point is true, this indicator will be on. If abnormality is identified, check if the indicator and input circuit are normal. Use of electronic switch with too much electricity leakage often results in unexpected actions of the input point.☼Output indicatorOn/Off of output point is indicated by the output indicator. When the output indicator (On/Off) does notcorrespond to the action of its load, please be aware of the following:1. The output contact may be melted or blocked due to an over loaded or short-circuited load, which will resultin poor contact.2. If you are suspicious that he output point may execute an undesired action, check the output wiring circuitand whether the screw is properly tightened.。

暖通负荷用户使用手册
BEC空调设计中，设计师大多采用单位面积负荷指标估算的方法进行负荷计算，由于计算方式偏于保守，计算结果偏大。致使主机、系统选型偏大，相应的初投资、运行、维护成本增加，造成资源的浪费。鉴于这种情况，在2004年 4月1日开始实施的《采暖通风与空气调节设计规范》（GB50019-2003）中明确规定“…除方案设计或初步设计阶段可使用冷负荷指标进行必要的估算之外，应对空气调节区进行逐项逐时的冷负荷计算...（6.2.1）”。同时，在《公共建筑节能设计标准》（GB50189-2005）中明确规定： “。。。施工图设计阶段，必须进行热负荷和逐项逐时的冷负荷计算”。 Bech正是为了满足这一需求而设计的，软件提供了逐项逐时冷负荷、采暖热负荷和空调热负荷的的计算功能。作为补充，软件仍然提供了负荷估算功能。以满足不同设计深度的需求。市面上也有许多同类软件，提供了类似的负荷计算功能。但这些软件在进行负荷计算前，往往需要输入大量的基础数据，不能直接利用已有的建筑模型，使负荷计算效率低下，编辑、调整繁琐。 Bech掘弃了以往繁琐的计算过程，使暖通空调专业的负荷计算变得简单易行。软件可以自动提取模型中的围护结构数据。构件也提供了丰富的属性已满足复合计算的需要。在负荷计算时，只需为构件对象设定相应属性，便可完成负荷计算过程。
