FOREWORD VM-11B For Use in Safety... Thank you for your using our VM-11B Acceleration Input Vibration Signal Conditioner. SHINKAWA Sensor Technology applies strict quality control and inspections to ensure the high reliability of its products. The VM-11 Series Conditioner Instruction Manual contains descriptive information, specifications, installation procedures and field wiring with monitor. Please study contents of this manual and related manuals thoroughly before installing or operating the equipment, and keep it handy for future reference.! CAUTION 1. If insulation resistance (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 the transducer and monitor. If this caution is not adhered to, the transducer and monitor could be damaged. 2. Do not measure insulation resistance and dielectric strength other than those at places specified. 3. Do not remodel this unit without permission. Otherwise the guarantee can not be made. 4. This unit is designed for use by specialists or persons thoroughly familiar with the field. 5. Make sure that the end user receives the instruction Manual delivered with this unit.! CAUTION The VM-11 series has an inrush current when power on. The inrush current value is varied depending on the situation like a timing for the power on or impedance of a power line, but normally it s value is several times or dozens of times lager than the current consumption. When the VM-11 is used in combination with a circuit protector, a delay type of circuit protector should be used. Before Use... When the unit is received, inspect it for damage suffered in transport and check whether it is the item you ordered. In the unlikely event that it was damaged in transport or does not function according to specifications, please contact the SHINKAWA Office or dealer nearest you. Avoid places where it is exposed to high humidity or corrosive gases. Accessories : Mounting block 2 : Tag. No. label 2 : Mounting screw ISO M4 0.7 4 i

4. MOUNTING METHOD VM-11B The VM-11 Series Vibration Signal Conditioner can be mounted on racks, walls or DIN rails.! CAUTION Be sure to recheck the mounting condition of the conditioner after completing installation work. The imperfect installation work may cause the damage of the conditioner by dropping. 4-1 RACK MOUNTING Use a panel (FRK-16) and install it on an angle as shown in Fig. 4.1. This is a convenient method for high density mounting of the conditioners on a 19-inch rack panel. (See Fig. 4.2.)

Mounting block Fig. 4.8-8-
5. EXTERNAL WIRING VM-11B Wires can be connected to terminals by opening the conditioner terminal cover. It is recommended that very flexible twisted wires be used for wiring, and good and reliable round crimp-on terminals (JIS C2805) be used.! WARNING To prevent electric shock, never turn on the power until all wiring is completed.! CAUTION The conditioner shall not be located near motor or relay side. Run input and output signal cables separately from power cables. If not, the output may be affected by the noise. 5-1 CONNECTION OF TRANSDUCER The transducer output signal line (+) shall be connected to the terminal No. 7. The common line and cable shield line of the transducer shall be connected to the terminal No. 8 (COM). The following wiring shall be recommended for connection between the transducer and the signal conditioner. In case of CA input transducer : 2-wire twisted pair shielded cable with 0.52 to 0.75 mm 2 COM SIG. 2-wire twisted pair shielded cable 1 2 3 4 5 6 7 8 Acceleration Transducer! CAUTION Refer to the instruction manual of transducer. In case the shielded wire is connected to the transducer case,do not connect the shielded wire to 8(COM) to avoid two point grounding. 9 10 11 12 13 14 15 16-9-
5. EXTERNAL WIRING VM-11B 5-2 CONNECTION OF WAVEFORM OUTPUT SIGNAL The waveform output signal (+) is output from the terminal No. 5 (+) and No. 6 (COM). Twisted (0.5 to 0.75mm 2 ) vinyl chord (VSF) as per JIS 3306 or equivalent is recommended for buffer output wiring.! CAUTION 1. The waveform output signal is not insulated against the input signal. 2. Insulate COM of the buffer output signal against ground to avoid external noise. 1 5 2 6 3 7 4 8 + - Waveform output receiving instrument 9 10 11 12 13 14 15 16-10-
5. EXTERNAL WIRING VM-11B 5-3 CONNECTION OF RECORDER OUTPUT (CONDITIONER OUTPUT) SIGNAL The recorder output signal is output from the terminal No. 11 (+) and No. 12 (COM). Twisted (0.5 to 0.75mm 2 ) vinyl chord (VSF) as per JIS 3306 or equivalent is recommended for recorder output wiring. 1 2 3 4 5 6 7 8 9 13 10 14 11 15 12 16 + - Signal output Receiving instrument -11-
5. EXTERNAL WIRING VM-11B 5-4 CONNECTION OF POWER SUPPLY (1) AC specification Connect L (LINE) to terminal 14 and N (NEUTRAL) to terminal 15. Also connect terminal 16 to ground. (2) DC specification Connect (+) to terminal 14 and (-) to terminal 15. Also connect terminal 16 to ground. Twisted (1.25 to 2.0 mm 2 ) 600V vinyl chord (IV) as per JIS 3307 or equivalent is recommended for power supply wiring.!

WARNING Beware of electric shock from high-voltage parts. -12-
6. ITEMS TO BE CHECKED BEFORE TURNING THE POWER SWITCH ON VM-11B (1) Confirm that the wiring from the input transducer is correct. (2) Make sure that 85 to 264VAC or 24VDC power cable of the conditioner is connected with the correct polarities. (3) Confirm that the external wiring to the terminal board is correct. (4) Check that the mounting conditions; ambient temperature, humidity, dust and vibration are suitable (e.g. within specifications). Confirm the above items before turning on the power supply. The conditioner needs 5 minutes warmup to meet its specified accuracy levels. -13-
7. BURN-DOWN FUNCTION VM-11B This converter is provided with the burn-down function to indicate the converter itself is not in the measurement state. The output of the converter is set to less than -20% of F.S. (0.8mADC or 0.2VDC) when the converter is in any of the following states. (1) The input transducer is abnormal (disconnected or shorted).! CAUTION The OFF-DELAY function is activated. Note that the burn-down function continues for about 10 sec after the input signal returns to the normal state and for about 10 sec after turning the power switch on. -14-
8. USING RADIO EQUIPMENT VM-11B If the signal conditioner, signal cable or transducer are exposed to electromagnetic waves, the conditioner cannot maintain its specified accuracy levels. Therefore, refrain from using transceivers or portable phones in its immediate vicinity -15-
