The factory default IP address configuration of the CiscoWAP361 is DHCP. Make sure that your DHCP server is running andcan be reached.See “Incorrect IP Address” for troubleshooting information, or ifyou do not have a DHCP server.S TEP2Locate the IP address of the Cisco WAP361.a.The Cisco WAP361 can be accessed and managed by Cisconetwork tools and services including the Cisco FindIT NetworkDiscovery Utility that enables you to automatically discover allsupported Cisco devices in the same local network segmentas your computer. You can get a snapshot view of each deviceor launch the product configuration utility to view andconfigure the settings. For more information, see/go/findit.b.The Cisco WAP361 is Bonjour-enabled and automaticallybroadcasts its services and listens for services beingadvertised by other Bonjour-enabled devices. If you have aBonjour-enabled browser, such as Microsoft Internet Explorerwith a Bonjour plug-in, or the Apple Mac Safari browser, youcan find the Cisco WAP361 on your local network withoutknowing its IP address.You can download the complete Bonjour for Microsoft InternetExplorer browser from Apple’s website by visiting:/bonjour/c.Locate the IP address assigned by your DHCP server byaccessing your router or DHCP server. See your DHCP serverinstructions for more information.S TEP3Launch a web browser, such as Microsoft Internet Explorer.S TEP4In the address bar, enter the default DHCP address and press the Enter key.S TEP5Enter the default user name of cisco and password of cisco in the Username and Password fields.S TEP6Click Log In. The Wireless Access Point Setup Wizard appears.10Cisco WAP361 Quick Start GuideS TEP7Follow the Setup Wizard instructions to finish the WAP device installation.We strongly recommend that you use the Setup Wizard for the firstinstallation. For more advanced configurations, see theAdministration Guide. A link to the Administration Guide is found in“Where to Go From Here”.Congratulations, you can now start using the Cisco WAP361.Suggested Next Steps7In case of an error while installing, try the troubleshooting procedures described in this section.TroubleshootingIf you cannot display the web-based Configuration Utility, you can test the ability of the computer to communicate with the Cisco WAP361 by using ping.T o use ping on a computer running Windows:S TEP1Verify that the Cisco WAP361is powered on and the lights if they do not indicate the appropriate links.S TEP2Locate the Cisco WAP361’s IP address. While there are different ways to locate the IP address, this procedure uses Cisco FindIT.a.If you have previously downloaded Cisco FindIT, open InternetExplorer and launch Cisco FindIT. For more information ondownloading Cisco FindIT, see /go/findit.b.In the Cisco FindIT display, place your mouse over the device’sname. The Cisco WAP361’s IP address is displayed along withother device information.S TEP3Open a command window by choosing Start > Run and enter cmd.S TEP4At the command window prompt, enter ping and the Cisco WAP361’s IP address. In this example, we pinged 192.0.2.10.If successful, you should get a reply similar to the following:Pinging 192.0.2.10 with 32 bytes of data:Reply from 192.0.2.10: bytes=32 time<1ms TTL=128Cisco WAP361 Quick Start Guide11If it fails, you should get a reply similar to the following:Pinging 192.0.2.10 with 32 bytes of data:Request timed out.Possible Cause of Installation FailureNo PowerPower up the switch and your computer if they are turned off.Make sure that your PoE switch is powered on and the lights indicate that you have a link. See “Verifying the Hardware Installation”.Verify that the devices on your network are not plugged into a switchable outlet.Bad Ethernet ConnectionCheck the state of the indicator lights. See “Verifying the Hardware Installation”.Check the Ethernet cable to ensure that it is firmly connected to your devices. Devices connected by the Ethernet cable can include the WAP devices, and routers, any switches, and your computer.Verify the connected switch has auto-negotiation enabled. The Cisco WAP361 and the switch need the same negotiation parameters set.Bad ImageAfter a new firmware installation, if the POWER light is solid red, which indicates that the device fails to boot with both firmware images, contact system support; see “Where to Go From Here”.Incorrect IP AddressThe most likely cause of connectivity failure is an incorrect IP address. The Web browser may be pointing to the wrong IP address, or your computer may be configured with an IP address that is not in the same subnet as the Cisco WAP361.Because the factory default IP address configuration is DHCP, make sure that your DHCP server is running and can be reached. You may need to disconnect and reconnect the devices for them to discover their new IP addresses from the DHCP server. You can then query the DHCP server for the new IP address. See Step 2 of “Getting Started with the Configuration” for more information on how to find the DHCP address.12Cisco WAP361 Quick Start GuideIf the Cisco WAP361 does not receive a DHCP response (there is no DHCP server on your network) after 60 seconds, the Cisco WAP361 will fallback to the following default static IP address: 192.168.1.245 and a default mask of 255.255.255.0. T o reach that IP address, be sure that your computer is on the 192.168.1.xxx network.Rebooting the Cisco WAP361 or Resetting 8to Factory DefaultsTo reboot your Cisco WAP361:•If the Cisco WAP361 uses a power adapter, with the power on, use the POWER button to reboot the device. The POWER button only functions when the Cisco WAP361 uses a power adapter.•If the power supply is PoE, unplug your Ethernet connection for three seconds and plug it back in.•With the power on, press the RESET button with an opened paper clip for less than 10 seconds, or until the lights go off.–When all the lights go off, release the RESET button.–Release the RESET button as soon as the lights go off, or you will restore the Cisco WAP361 to factory default settings and lose yourconfigurations.To reset the Cisco WAP361 to factory default settings:•With the power on, press and hold the RESET button with an opened paper clip for more than 10 seconds.–All of the lights will go off.–Release the RESET button when the power light turns on.Cisco WAP361 Quick Start Guide1314Cisco WAP361 Quick Start GuideWhere to Go From HereFor EU lot 26 related test result, please check this web page:/go/eu-lot26-results .

5、其他操作说明
5.1运行和筛选
系统上电后,自动进入运行状态;在设置菜单操作状态下按“运行”键,系统进入运行状态。在运行状态下,二次表前面板双色发光柱指示电极状态——绿色代表对应电极有水,红色代表对应电极无水。在运行状态下按“筛选”键,筛选指示灯亮,系统进入筛选运行状态;再按“筛选”键,取消筛选。在非筛选状态下,发光柱显示与电极状态完全对应,数码管显示最高有水点,电极全无水时数码管显示“OFF”;在筛选状Байду номын сангаас下,系统从高位向低位搜索,将第一个连续两点有水的电极位置确定为当前水位,发光条显示剔除单红、单绿夹杂的状态。
一、用途:
LHDJ-1.6-32型系列电接点式液位计主要用于各种锅炉汽包、储集器、除氧器、蒸发器、加热器及水箱的水位测量。其二次仪表具有触点报警输出,可直接参与闭环控制系统和连锁控制系统,增强型二次仪表具有4~20mA变送输出功能。
二、结构及工作原理:
1、液位计构成
电接点式液位计主要由测量筒体、陶瓷电极、二次仪表等几部分构成,见图1。
5.2消音:
在系统处于运行状态时按“消音”键,消音指示灯亮起,禁止报警时发声;再按“消音”键,取消消音状态。
6、高、低报警的逻辑判断
高、低报警输出均以水位状态(有筛选或无筛选)为开启限定。运行时,优先判定高报状态。在有高报的情况下,封锁低报,即使低报值设定比高报值还高,也是如此,这样可避免逻辑混乱。高报时,无论有无筛选,必须该点向下连续两点有水方可输出;低报时,同样向上连续两点无水方可输出,这样处理和有些用户在报警点装两个平行电极相与的效果是一样的,且逻辑上更为可靠。
3、测量筒结构:
测量筒是液位计取得水位信号的重要设备,长度及测量点数按用户要求而定。

1.2工作压力:1.0~21.5MPa
1.3工作温度:饱和温度
1.4接口方式:法兰连接或焊接
1.5连通管规格:φ38×5
4.3低报设定
在功能菜单操作状态下按“设置”键选择功能3,数码管显示:“3--CC”,此时按“确认”键进入低报设定功能。仪表发光柱第一个电极点被选中(选中点为绿色,其余为红色),数码管显示对应的水位值。如报警输出指示有灯亮起,则表示该电极点已被设成对应报警通道的低报报警点,此时按“清除”键可取消该报警点设置,按“确认”键保持当前电极设置同时指向下一电极点;如报警输出指示没有灯亮起,表示该电极未被设成低报报警点,此时按“确认”键忽略该点并指向下一电极点,按“设置”键,可将该点设置成报警点。

上电后,系统自动进入运行状态。在运行状态下按“设置”键,设置指示灯亮,系统进入功能菜单操作状态,可在此状态下进行各种功能设定。在功能菜单状态下按“运行”键,运行指示灯亮,系统进入正常运行状态。
4.1水阻设定
在功能菜单操作状态下按“设置”键进行功能选择。选择功能1,数码管显示:“1--AA”,此时按“确认”键进入水阻设定功能,数码管低两位显示当前水阻值。在设置过程中,按“位+”、“位-”键进行位选,选中位闪烁;按“+1”、“-1”键进行选中位数值调整,调整到希望数值后,按“确认”键输入并保存。水阻数值的选择对仪表工作过程中抗干扰性有一定的影响;一般情况下,水阻值越低,电极对水的反应灵敏度越高。根据实验,一般用户的水阻值应设定在60-90之间(出厂设置一般为60)。用户可根据现场实际情况,向水阻大和小两个方向试设定,直至水位显示不正确后,取中间值作为水阻设定值。

2、二次仪表
二次仪表显示为双色光柱形式,以区分水与汽,其中液相部分为绿色,汽相部分为红色,同时具备数码显示功能,直观显示水位。二次仪表操作采用功能菜单方式,水位设定最大指示为24点,7路可在线编程的任意高低位报警输出(面板有报警指示灯),全部参数均可在线设定,并具有掉电记忆功能。由于二次仪表是通用型设计,故可适应国内不大于24点水位、输出不多于7路开关量的各种电接点测量筒及各种地域的水阻值。同时,二次仪表利用CMOS高输入阻抗的特点,信号输入回路仅有微电流通过电极,可以使被测液体对电极的化学腐蚀减少到最低限度,以延长电极的使用寿命。
在功能菜单操作状态下按“设置”键选择功能5,数码管显示:“5--EE”,此时按“确认”键进入报警方式设定功能。此时数码管显示“----1”,右侧第一位显示“1”代表“与方式”,显示“0”代表“或方式”;可通过“+1”、“-1”键进行方式切换,按“确认”键保存设置并退出,按“退出”键取消操作并退出。
