Terminal SG (for RS-485) is connected to terminal 2 in the terminal
block inside the unit.
Note: The default setting is enclosed in brackets, [ ].
*1. A minor failure does not affect control output but a check should be
made for waveform record and clock data storage errors, as well as
clock data errors. The installation conditions should also be checked.
While LED 4 (green) is lit, LED 1 (red) is lit and digital output 1 (DO1)
turns ON. In any mode other than measurement mode, DO1 repeatedly turns ON and OFF. In addition, by changing the setting, it can be
made to turn ON only when a minor failure occurs.
*2. A serious failure may affect control output such as vibration detection
output and liquefaction detection output.
While LED 4 (green) is lit, LED 2 (red) is lit.
Then digital output 1 (DO1) turns ON.
Note that when a serious failure occurs, minor failure output (DO1) is
also generated.

•
Keep wiring away from cables connected to a commercial power supply or motor drive power supply that is likely to produce electrical
noise.
•
If this unit is used alone, its miswiring protection is effective. However if multiple units are connected through RS-485, miswiring of the
power source may cause device failure. Be sure to check that the wiring is correct before turning the power on.
•
For screw terminal connections, use crimp terminals that are the correct size for M3.5 screws.
•
For spring screw terminal connections, use wires whose nominal cross-sectional area is 0.25 to 0.75 mm2 (24 to 18 AWG), with bootlace
ferrules. Use bootlace ferrules and a crimping tool that comply with the following standards.
Do not insert stripped or soldered ends of stranded wires into the spring terminal block.
Bootlace ferrule: DIN 46228 sect. 4
Crimping tool: DIN 46228 parts 1 and 4
The compatible bootlace ferrules and crimping tool made by
Weidmuller Japan Co., Ltd. are shown on the right.
•
To connect a wire to the spring terminal block, insert a bootlace ferrule into the hole (push-in system).
•
To remove a wire from the spring terminal block, push the button on the block using a flat-head screwdriver (tip size: 0.4×2.5 mm) and
pull out the wire. The standard pushing force on the button and the pushed distance are 20 N and 1.7 mm respectively. If the pushing
force on the button is 40 N or greater, device failure could result.
•
For wiring for RS-485, do not connect an external terminating resistor.
•
For wiring, follow the wiring diagram.
•
Use shielded cables. Use a shielded cable to wire the ground terminal inside the case.
•
Use either of the following methods so that there is only one ground connection.
(1) Ground the other end of the shielded cable that is connected to the ground terminal inside the case.
(2) Ground the ground terminal that is outside the case.
The ground connection should have a resistance of 100 Ω or less.
•
If the battery included with this unit is not used, the clock data and recorded waveform data will not be backed up while power is not
being supplied. In this case, the unit will have a minor failure status.
•
If the battery is not connected to the unit or if the clock is not set, the unit will have a minor failure status.
•
If the removed battery is connected to the unit again, the unit may
take time to recognize the battery. Until it is recognized, the unit
will have a minor failure status.
•
If there is a risk of power surge caused by lightning, use Azbil
Corporation’s FA SurgeNon surge protector (QN430C series).
Make the wiring between the unit and the SurgeNon as short as
possible.
