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

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.

• 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)
