四、正 文:1 开机1.1 把仪器水平放置在桌面上1.2 接好电源线,按下电源开关鍵,键内指示灯亮,同时前面板上数码管开始显示,粒径部分显示“P ”,读计数部分显示“0”仪器已处于等待状态 ,并预热15分钟。
2 仪器自检(可在预热时间内进行)(1)按一下面板上“自检”键,相应的指示灯亮。
同时数码显示由,然后等待1分钟,由示粒径0.3μm 、0.5μm 、1μm 计数值为992208,显示粒径为3μm 、5μm 、10μm 的计数值为9168,则可进一步证实仪器正常。
)(2)状态方可进行以下步骤。
3 实时时钟校正它可以正确指示某一次测量工作的年、月、日、时,并能打印出来,为用户存档提供 方便。
(1) 当面板上数码管显示为 时即仪器处于等待状态,才可进行实时时钟校正。
(2) 按一下时钟键,相应的指示灯亮,同进数码显由 变为。
“1”表示年份,可按“+”或“-再安一下“时钟”键(指示灯亮),数码管显示变为“2”表示月份,-”键输入正确的月份。
在按一下时钟(指示灯亮)数码管显示变为 。
“3-”键输入正确的日数。
依此类推 ,“4状态。
(3)在打印测量数据的同时需要打印实时时钟数,则“时钟”的指示灯必须处在亮的状态,如不要打印出实时时钟数,则可取消“时钟”,时钟指示灯灭。
(4)一般情况实时时钟无需经常校正,但在长期不用后再次测量时进行校正,也是必要的。
4、测量周期设定(1)如果测量周期定为1分钟一次,则不必进行这步操作,因为微机电脑自行设定将测量周期设为1分钟,无需人为在设定。
(2)如果测量周期不为1分钟一次,则必须进行设定,具体步骤如下:在仪器等待 状态时,在面板上按一下“周期”键,相应的指示灯亮,同时数码管显示由 变为 ,F 表示进入周期调整状态,n 是测量周期由2分到+”或“-”键的增减来达到相应的周期。
第一章前言1.1 概述我公司自成立以来一直致力于称重控制仪表的研究,并吸收了在称重控制仪表上处于世界领先水平的美国拉姆齐、德国申克和日本大合先进的科技技术,并以国内厂矿企业使用的皮带秤及称重控制系统的经验和实际地要求为基础,自行研制开发了3011型称重控制仪表。

K K-38The LVCN-300 Series is designed from an operator’s point of view, making any process and alarm points visible on the multi-colored display graph. They get everything they need at a glance! The LVCN-300 Series provides reliability with very flexible design options and a friendly face to tell you exactly what is going on inside your tank no matter where it is located. Everyone can easily see it from a distance or while walking the plant floor. It’s this simple to understand—if the green vertical bar (level) is between the orange and yellow line everything’s just fine. If it’s above or below the red marks, something is wrong. That is all there is to it. The LVCN-300 Series accepts all types of 4 to 20 mA sensors, such as pressure, ultrasonic, float type liquid level transmitters and capacitive transmitters. The sensor input is isolated and loop powered up to 24 Vdc, allowing data gathering devices to easily interface. Two models are available, the LVCN-301 or LVCN-302. The LVCN-301 is for Make Up applications and the LVCN-302 is for sump applications. A typical Make Up application is when the liquid in a tank is “lost” because it is being used in a manufacturing process or lost by evaporation and has to periodically be refilled or “made up”. To accomplish a Make Up operation the LVCN-301 controller uses a differential relay that is activated by a FALLING level in the tank. The same relay is going to turn the pump or valve ON and OFF. First you need to program the Make Up ON level where you want to begin refilling the tank with liquid. When the level FALLS or DECREASES to this point, the controller will CLOSE or activate the relay and turn ON a pump or valve and begin refilling the tank. The LVCN-301 controller has internally “latched” the relay closed and will continue holding it closed until the Make Up OFF level that was programmed is reached and the tank stops filling. A typical Sump application is when the liquid in a tank is being collected and has to periodically be transferred or pumped out to prevent an overflow. A basement with a sump pump is doing the same type of operation. To accomplish this Sump Operation the LVCN-302 controller uses a differential relay that is activated by a RISING level in the tank. The same relay is going to turn the pump or valve ON and OFF. First you need to program the SUMP ON level where you want to begin draining the liquid in the tank. When the level RISES or INCREASES to this level the controller will CLOSE or activate the relay and turn on a pump or valve and begin draining the tank. The LVCN-302 controller has internally “latched” the relay closed and will continue holding it closed until the Sump OFF level you programmed is reached and the tank stops draining.For 24 Vac power, add “-24VAC” to model number.
