WARNING
Warnings are indicated when mishandling this product might result in death or serious injury to the user.
CAUTION
Cautions are indicated when mishandling this product might result
in minor injury to the user, or only physical damage to this product.
WARNING
This device is certified as a pressure-resistant explosion-proof
construction (Ex d IIB T4). Install it in a location that complies with
this certification.
When there might be an explosive atmosphere do not open the
cover.
If you use the Smart Loader Package (sold separately), do so in a
non-hazardous area where there is no danger of explosion or fire.
Always use the cable gland and flameproof packing set supplied
with this unit. Use packing that is appropriate for the cable. If
the wrong packing is used the unit will no longer be a certified
explosion-proof product.
E1
WARNING
Use cables with a heat resistance of 80°C or more. If a cable with
a heat resistance of less than 80°C is used the unit will no longer
be a certified explosion-proof product. Moreover fire or device
failure may result.
After wiring work be sure to firmly tighten the cover screws.
Otherwise the unit will not satisfy the conditions for a pressureresistant explosion-proof construction.
In Taiwan, this device cannot be used in an explosive atmosphere.
Before doing wiring work be sure to disconnect the power. Failure
to do so may result in an electric shock.
If the cover is open in a hazardous area do not turn on the
electricity.
CAUTION
Only specialists with the proper knowledge and technical skill
concerning this type of equipment and this unit should carry
out the installation, wiring, inspection, and maintenance work.
This device does not incorporate any countermeasures against
lightning. As necessary, take appropriate measures to protect
equipment from lightning.
Do not use a walkie-talkie or other transceiver within 2 m of this
unit or cables connected to this unit. Doing so might cause this
unit to malfunction.
Use shielded cables for wiring.
Be sure to carry out the wiring work properly. Incorrect wiring
may cause device failure.
Take special care that crimp terminals (etc.) are not in contact
with adjacent terminals.
For control of critical equipment (e.g. for earthquake emergency shutdown), to avoid dependence on a single output use
this earthquake sensor together with another one, or use a
2-out-of-3 configuration.
If this unit malfunctions its electrical output may be incorrect.
If equipment safety might thereby be endangered, consider
having a fail-safe design for the system as a whole, with compartmentalization of controller and limits and with duplexing;
or use a redundant design.
Interference from a shock wave or electromagnetic wave may
activate the noise protection function of this unit preventing
vibration detection output or AO/DO output.
Do not subject this device to shock that exceeds the operating
conditions stated in the specifications. Doing do so may cause
device failure.
Handle the case and cover with care. If the threads are damaged, the cover will not open and close properly.
This device is a precision instrument. Impact from a 1cm fall is
enough to damage the internal sensor.
Be sure to handle it carefully. Take care to prevent impact when
removing this unit from the box, placing it on the floor temporarily during installation, etc.
During installation, take care not to bump this device against
metal objects such as pipes.
When connecting the wiring, be sure not to hit the sensor with a
crimping tool screwdriver or other tool.
When tightening the cable gland with a wrench, do not hit the
wrench with a hammer.
If there is a risk of impact to this unit after it is mounted install a
protective cover or like.
Do not disassemble or modify this device.
Do not subject this unit to impact or shock from a wrench or the
like when removing the unit for periodic inspection, etc.
When sending this unit back to Azbil Corporation for periodic
inspection, pack it in the shipping package specially made for it.
Contact the azbil Group for the shipping box.
Handling Precautions
•
Do not remove the seal from the cable gland connection
port until the wiring work is about to begin.

OVERVIEW
The Intelligent Earthquake Sensor calculates seismic intensity (SI), which represents estimated structural damage, and the Japan Meteorological
Agency (JMA) seismic intensity scale (shindo scale) equivalent value, based on acceleration signals generated from the built-in servo accelerometer.
Additionally, the unit judges ground liquefaction from the acceleration waveform characteristics and outputs the results.

INSTALLATION
W ARNING
This device is certified as a pressure-resistant explosion-proof construction (Ex d IIB T4). Install it in a location that
complies with this certification.
In Taiwan, this device cannot be used in an explosive atmosphere.
CAUTION
During installation or maintenance work, take care not to drop the unit accidentally to prevent injury to feet etc.
This device does not incorporate any countermeasures against lightning.
As necessary, take appropriate measures to protect equipment from lightning.

Doing do so may cause device failure.
Installation Location
Avoid installing the device where it will be subject to conditions such as the following.
•
Ambient temperature below −10°C or above +60°C
•
Humidity higher than 90%RH
•
Sudden temperature fluctuations causing condensation
•
Corrosive or combustible gas
•
Large amounts of conductive substances (e.g., dust, salt, or iron powder) or organic solvents
•
Direct shock or vibration other than earthquake motion
•
Direct sunlight
•
Large amounts of water or rain
•
Splashing by fluids (e.g., oil or chemicals)
•
Strong magnetic or electrical fields
Installation Instructions
This unit measures ground acceleration caused by earthquake motion in order to calculate the estimated amount of damage.
Installation of this unit on a concrete foundation separated from buildings is recommended so that building vibration does not affect measurement.
In addition, where needed to prevent direct exposure to sunlight or rain, provide a protective roof or cover.
Handling Precautions
•
Do not use the three adjustment holes (which are for manufacturer use only) when installing
the unit.
•
When installing the unit on a concrete foundation, check that the foundation is not hollow by
tapping it with a small hammer.
When installing this unit, select one of the methods shown below depending on the installation
conditions.
If the installation surface is level within ±3°
(1) Select a flat concrete surface for installation.
(2) Put three anchors or plug bolts in the surface, aligned with the three 7mm
mounting holes in the unit.
(3) Attach the unit with the three mounting screws (M5×30mm).
If the installation surface is not level
(1) Get a metal plate (10mm thick or more) with three holes for level adjustment
and three threaded M5 holes for attaching the unit.
The dimensions of the mounting plate are shown on the right.
