These tripping characteristics are mean values of the spread at 20 °C ambient temperature in a cold state. Tripping time depends on response current. On devices at operating temperature the tripping time of the overload relay drops to approx. 25 % of the read value. Specific characteristics for each individual setting range can be found in the manual.

InstallationProcessPro transmitters are available in two styles: panel mount and fi eld mount. The panel mount is supplied with the necessary hardware to install the transmitter. This manual includes complete panel mounting instructions.Field mounting requires one of two separate mounting kits. The 3-8051 integral kit joins the sensor and instrument together into a single package. The 3-8050 Universal kit enables the transmitter to be installed virtually anywhere.Detailed instructions for integral mounting or other fi eld installation options are included with the 3-8051 Integral kit or the 3-8050 Universal kit.SIDE VIEWField Mount w/8051 Integral kitSIDE VIEWField Mount w/8050 Universal basePanel MountSIDE VIEWFRONT VIEWField Mount &Panel Mount1.

They have no effect on calculations. They may be any alpha or numeric character, upper or lower case.The last character sets the Flow rate Timebase. Select S (seconds), M (minutes), H (hours) or D (days).This setting tells the transmitter how to convert the input frequency from the flow sensor into a fl ow rate. The K-factor is unique to the sensor model and to the pipe size and schedule. Refer to data in the sensor manual for the correct value. Limits: 0.0001 to 99999. (The K-factor cannot be set to 0)This setting identifi es the Totalizer units. It has no effect on any calculation. It serves as a label only. Each character can be any alpha or numeric selection, upper or lower case.This setting tells the transmitter how to convert the input frequency from the flow sensor into a volumetric total. It also is used as the basis for the Open Collector pulse mode.The setting is usually the same as the Flow K-factor, or different by x10 or x100. Limits: 0.0001 to 99999. (The K-factor cannot be set to 0)Select the minimum and maximum values for the 4-20 mA Current loop output. The 8550 will allow any values from 0.0000 to 99999.Select the desired mode of operation for the Open Collector output. Options available are High, Low, volumetric Pulse, or Frequency. The signal may be disabled (Off) if not used.In Low or High Mode, the Open Collector output will be activated when the Flow rate reaches this value. Be sure to modify this setting if you change the Flow Units.The Open Collector output will be deactivated at Setpoint ± Hysteresis, depending on High or Low Setpoint selection. (See details on page 4.)In Pulse mode, the Open collector output will generate one pulse when this volume of fl ow passes the sensor. The measurement is based on the Total K-factor. The 8550 will allowany value from 0.0001 to 99999.In Pulse mode, this setting defi nes the duration of the Open Collector output pulse. The 8550 allows any value from 0.1 seconds to 999.9 seconds.In Frequency mode, the Open Collector output will simulate the sensor frequency, divided by this setting. Set for 1 (input frequency = output frequency). Set for even numbers(2, 4, 6, 8 . . . 254 maximum) to scale output frequency.Use this “note pad” to record important dates, such as annual recertifi cation or scheduled maintenance.Calibrate MenuDisplay(Factory settings shown)DescriptionFlow Units:GPM >Flow K-Factor:60 >Total Units:Gallons >Total K-Factor 60 >Loop Range: GPM000.00 → 100.00 >Output Mode:Low > Output Setpnt:10.0 GPM >Output Hys:5.0 GPM >Output Volume:100.00 Gallons >Output PlsWdth:0.1 Seconds >Output Freq.:Divide by1 >Last CAL:4-20-06Options Menu10 s2 s20 s30 s40 s50 s60 s70 svery quickly.

目录第一章 SDH原理 (2)第二章马可尼SDH光端机 (5)第一节SMA16-64产品简介 (5)第二节单元描述 (6)第三节单元卡介绍 (10)第四节功能概述 (13)第三章设备预防性试验 (14)第一节设备预防性试验项目 (14)第四章设备日常巡视项目 (19)第五章设备运行维护注意事项 (22)第一章 SDH原理一、SDH定义：同步数字序列SDH（Synchronous Digital Hierarchy）,是有关通过物理传输网络,传送适配的的净负荷标准化数字传输结构的一个系列集。
二、SDH等级速率:ITU-TG.707中规定了SDH的各等级速率。
其中最基本的模块是STM-1，速率为155。
52Mbit/s，更高等级的是STM-N，其中N为正整数，即N=1，4,16,64。
三、SDH中STM—N 帧结构SDH帧结构是一种矩形块状结构，由270×N列和9行字节组成，每个字节有8bit。
帧中字节是从左往右，从上往下按行进行传输的，传完一帧再传下一帧，每秒共传8000帧。
每个基本帧的周期为125μs，即帧频为8kHz，每个字节为8bit，则STM-1的速率为: Fb=8000×270×9×8=155520000bit/s=155。
52M bit/s由下图可以看出，SDH帧结构大体可以分为三个区域（1）段开销区域:为保证信息净负荷正常灵活传输所必需的附加字。
（2）管理单元指针：用来指示信息净负荷的第一个字节在STM-N帧内准确的位置，以便在接收端正确分解的指示符。
（3）信息净负荷区域：帧结构中存放信息的区域.三、四、SDH复用基本概念：（1）映射：将各支路适配进相应的VC中称为映射。
（2）复接：将多个低阶通道层信号适配到高阶通道，或将多个高阶通道信号适配进复接段的称为复接。
（3）定位：将VC放进支路单元或管理单元，同时将其与帧参考点的偏差也作为信息结合进去的过程为定位。

金属膜电阻（RJ）
材料：通过真空蒸发或阴极溅射，沉积在陶瓷肌体表面上一层很薄的金属或合金膜。
特点：金属膜电阻比碳膜电阻的精度高，稳定性好，噪声，温度系数小，金属膜电阻由于结构不均匀，因此使他的脉冲负载能力差。
