GENERAL MONITOR SPECIFICATION  
Display : Display measurement value and alarm set value on  
  7-segment LED. 
Vibration measurement function 
 : Measure vibration of displacement or velocity,  
  acceleration. (The number of input channels is  
  selected from Model Code.) 
Isolated recorder output   
 : Output a signal (isolated) proportional to  
  measurement value (The number of output channels  
  is selected from Model Code.) 
Relay output : Output contact signal from relay. 
  (The number of output channels is selected from  
  Model Code.) 
Modbus/TCP communication 
 : Output of data by Modbus protocol

2CHANNEL VIBRATION MEASUREMENT FUNCTION  
Input Points  
Input points : 2 channel / slot 
 
Input Transducer*1  
Eddy current transducer : FK-202F 
  Displacement vibration mesurement 
Velocity transducer : CV-86, CV-87 
  Velocity vibration measurement or  
  displacement vibration measurement 
Acceleration transducer : CA-302 
  Acceleration vibration measurement or  
  velocity vibration measurement 
Other transducer : Voltage signal 
 
Vibration Measurement  
Monitor type*1 : Displacement vibration, Velocity vibration,  
  Acceleration vibration 
Monitor range*1 : 1 to 1000 
   Unit  : μm, mils, mm/s, in/s, m/s2, g  
   Measurement detection : pk-pk、pk、rms 
Rectification : Avarage value 
Measurement range(AC) : 0 to 9V pk 
  The input voltage of 100% of F.S. at 100Hz should be 
  within the range of 39.4mV pk to 9V pk. 
Measurement range (DC) : 0 to 22VDC（CV-86, CV-87, CA-302 input） 
 -22 to 0VDC（FK-202F input） 
Input voltage range : -24 to 24VDC 
Input impedance : Approx. 50kΩ 
 
Frequency Response*1  
4 pole high-pass filter  : 2Hz, 5Hz, 10Hz, 20Hz (-3db)  
2 pole low-pass filter : 500Hz, 1kHz, 4kHz, 10kHz (-3db) 
             
Sequence Function*1  
Used to prevent alarm output that is caused by excessive vibration during 
machine startup. Block off the DANGER/ALERT alarm, or switch the alarm 
setup value to another number magnified by setup number. 
Sequence Setup Value : 0(Block off), 1 to 10 (0.5step)  
△ ! WARNING 
 The sequence function may leave the machine unprotected. 
 In case the SEQ. magnification number is set up “0“, machine is 
unprotected as alarms are disabled. 
 In case the SEQ. magnification number is set up from 1.5 to 10.0, and 
SEQ. function is in effect, alarm set points are multiplied by the set value. 
 If the number is more than 150% of the monitor range the alarm may not 
output. 
 
Suppression Function*1  
If the vibration value is less than the setup value, this function is forced to 
suppress the measured vibration value and recorder output*2.  
Suppression Setup Value*3: 0 to 5% ( 0.1% step)  

Burnout Function*1  
When an OK alarm occurs (Output defeat function: ON) or at the monitor 
startup, the recorder output and the measurement value are controlled as 
follows. 
Burnout function setting 
Burnout setting value Burnout 
Recorder output value Mesurement value 
Down Scale 0% Equivalent to “0” of the 
measurement value 
0 
Down Scale 0mA / 0V 0V or 0mA 0 
 
Conversion Accuracy  
I/O Conversion Accuracy :±1.5% of F.S. at 100Hz at 25°C 
   ±3.0% of F.S. at 100Hz at -20 to +65°C
