VM-5C SST-2194-001-P001G Vm-5系列监视器型号vm-5s双转速表

概述
这是一个高度可靠的监视器,监测转子的转速和零转速。
可提供10槽机架安装型和内置电源的单单元独立型,因此它可以灵活地响应从中小型旋转机械到TSI的任何系统设计。还可以设置转速比较值,与转速(包括零转速)进行比较。它有一个内置的自诊断功能,通知输入换能器故障的操作员。
特性
•符合API St 670
•监视器可作为单个单元独立类型或机架安装类型。
•具有自诊断功能。
•允许操作员在现场更改每个设置。
•测量值、报警设定值、间隙电压等重要信息正常显示。

特性
•符合API St 670
•监视器可作为单个单元独立类型或机架安装类型。
•具有自诊断功能。
•允许操作员在现场更改每个设置。
•测量值、报警设定值、间隙电压等重要信息正常显示。
•可隔离记录仪输出(可选)。
•LED显示/触点输出(危险/警报报警)。
•LED显示/触点输出(输入异常报警)
*对于报警输出接线,请按照vm – 5g单单元仪表机架和VM-5Y继电器模块单元与本监视器组合使用的说明手册中的说明进行。
对传感器与监控器之间的信号线进行了1兆欧测试。从传感器和监视器上断开电缆。在将电缆连接到传感器和监视器之前,请确保放电已充电的负载。如果不遵守此注意事项,传感器和监视器可能会损坏
当使用VM-5S双转速表设计零转速系统时,避免仅使用SHINKAWA系统进行控制,而总是使用其他类型的检测系统在该系统中添加其他条件。如果只使用VM-5S双转速表进行控制,当监视器或传感器故障或与传感器连接不完美时,可能会导致机器严重损坏。因此,如图所示,为了可靠性和安全性,系统应设计为冗余的其他停止条件(例如。低转速继电器触点和定时器的组合
*对于零速度监控,使用RD速差驱动器或FK驱动器,能够检测不完美的连接,并指定“手动”触发模式。
·对于磁性拾音器的输入信号,磁性拾音器的输出电压(pk-pk)根据齿轮齿的大小、设定间隙、转速等而变化,在某些条件下可能会变成高压。因此,保持在磁性拾取器输出电压不超过监视器输入电压范围(100Vpk-pk)的范围内。

OVERVIEW
This is a highly reliable monitor which monitors the rotative speed and zero speed of the rotor.
Both a 10-slot rack mounting type and a single-unit independent type with a built-in power supply are available so that it can respond flexibly to any system design from medium and small scale rotating machinery to TSI. It is also possible to set a speed comparison value for comparison with the rotation speed (including zero speed). It has a built-in self-diagnostic function to inform the operator of input transducer failures.
FEATURES
• Conforms to API St’d 670
• The monitor is available as a single unit independent type or a rack mounting type.
• Has a self-diagnostic function.
• Allows the operator to change each setting even in the field.
• Important information such as measured value, alarm set value and gap voltage is normally displayed.
• Can isolate recorder output (option).
• LED display / contact output (DANGER / ALERT alarm).
• LED display / contact output (Input abnormal alarm)
*For alarm output wiring proceed as described in the instruction manuals for theVM-5G Single Unit instrument Rack and VM-5Y Relay Module Unit used incombination with this monitor unit.
“lf megger test is made on the signal cable between transducer and monitor.disconnect the cable from transducer and monitor.Be sure to discharge the charged electric load before connecting the cable to thetransducer and monitorIf this caution is not adhered to, the transducer and monitor could be damaged
.When a zero-speed system is designed using this VM-5S Dual Tachometer, avoidperforming control only by using SHINKAWA system, and always add othercondition to this system by using other kind of detection system. lf control isperformed only by using this VM-5S Dual Tachometer, it may result in criticaldamage on the machine when the monitor or transducer fails or an imperfectconnection to the sensor occurs.Therefore, as shown in the figure , for reliability and safety, the system should bedesigned with other stop conditions as redumdancy (example. combination oflow-revolution speed relay contact and timer until stop)
*For zero-speed monitoring, use an RD tacho driver or FK driver that is capable ofdetecting imperfect connections, and specify “Manual” trigger mode.
·In the case of the input signal from a magnetic pickup, the output voltage (pk-pk) ofthe magnetic pickup varies depending on the size of gear teeth, the set gap, rotationspeed, etc. and under certain conditions may become high voltage. Therefore, staywithin a range in which the output voltage of the magnetic pickup does not exceedthe monitor input voltage range (100Vpk-pk)
