1-1 For safe use of the product
This section describes correct use of this instrument to prevent safety hazard to the people and of their
properties.
If the instrument is used in a manner not specified by manufacturer, the protection provided by the
instrument may be impaired.
Please read and understand the contents of this instruction manual and make sure to observe following
warnings and cautions.
1-1-1 Preconditions for use
1. This product is a general product of component type (measuring unit) that is to be used by mounting
it on a panel for instrumentation inside a room. Do not use it in any other condition. (Expect for
portable type.)
2. Design fool-proof and fail-safe on the final product side and inspect regularly and use the product
after checking safety of the system. Regarding the use of a device that anticipates a big loss due to
failure of the product, always install a safety device for preventing these losses.
3. This is an instrument used for industrial application. Ask instrumentation specialist for installation,
wiring, adjustment and operation of the product.
To ensure quality, reliability and safety of the product, understand and strictly observe specifications,
warnings and cautions in a catalog, specifications and instruction manuals.
4. This product is not intended for use in human-life and property related applications such as nuclear
and radiation related equipment, medical equipment, aerospace equipment, railroad, and marine
transportation equipment. To use this product for equipment that requires high quality and safety
that affects human-life and property, design and install the protection and safety circuits to ensure
safety at your own responsibility.
1-1-2 Cautions for long term usage
1. To use the product in a good condition for a long time, regular parts replacement is recommended
for preventive maintenance. Refer to recommended parts replacement period mentioned later and
replace parts.
2. Troubles such as smoke and electric shock may occur due to wear endurance on mechanical parts
like relays and switches, deteriorations on electric parts such as electrolytic capacitor and insulation
of other parts used in the product.
5 to 10 years are reference to update of the product if there is no specific indication on the
specifications or the instruction manuals depending on the product's working environment and
operating status.

arning
To avoid major accidents, make sure to read and understand the
followings and use the product.
Check the power supply voltage and wiring
Before supplying the power to the product, check that the wiring is correct and power supply voltage
matches with the rated voltage etc.
Install circuit breaker
This product does not have a power supply switch. Install a circuit breaker that matches the rating
specifications in the power supply of the product.
Protection of terminal
To prevent electric shock, provide the terminal of the product with safety measures such that the user will
not be able to touch the final product directly.
Install safety device
Regarding the use of a device that anticipates a big loss due to failure of this product and the peripheral
devices, always install a safety device for preventing these losses and implement fail safe design in the
final product.
Do not put your hands inside the product
Do not put your hand and tool inside the product. You may get an injury or an electric shock.
Power cut off in case of suspicion
If there is offensive smell, strange noise or smoke or if the temperature increases abnormally, it is very
risky hence cut off the power supply immediately and contact the dealer or nearest CHINO's office.

*1 It can be specified when (6) Control output 1 is "1", "3", "5" or "6"
*2 It can be specified when (12) 2 Alarm event output points + Heater disconnection detection is "0" or "1".
*3 When specification with (7) Control output 2, number of alarm event output points is only 1 point [EV 2].
*4 It can be specified when (6) Control output 1 or (7) Control output 2 are "1" or "5" and (10) Remote signal input
+ 2 External signal input points is "0", "5" or "7".
If (6) Control output 1 and (7) Control output 2 are both "1", it can be operated with Control output 1.
*5 Alarm event only functions on mechanical relay, so check for the event function and select it.

1-3 Mounting condition
Caution
To avoid accidents, make sure to read and understand the followings.
Use the instrument in the mounting condition.
1-3-1 Environment
 Indoor use
 Away from direct sunlight.
 Away from high temperatures.
 Where there are no vibrations and shocks.
 Away from liquids (water etc.).
 Away from condensation.
 Industrial environment
(Overvoltage category: II, Transient overvoltage: 2500V, Pollution degree: 2)
1-3-2 Surrounding condition
 Away from strong noise, static electricity, and electric field and magnetic field etc.
 Surrounding temperature within -10 to 50°C (Less than 40°C in case of closed instrumentation),
surrounding humidity within 20 to 90% rh.
 Variation in temperature is less.
 Away from corrosive gas, explosive gas, ignition gas and combustible gas.
 Away from salt, iron and conductive material (Carbon, iron etc.).
 Away from steam, oil and chemicals etc.
 Away from dust etc.
 Away from the surroundings where high temperature is generated.
 Away from places where temperature remains stored (To avoid increase in internal temperature,
ensure the ventilation space. However, avoid direct wind to the terminals, it may cause unstable
indication.)
 Lot of space above the upper part of the instrument.
 Place where display screen can be easily seen. (This instrument uses LCD therefore if it is seen
from ‘above’, ‘below’, ‘left’, ‘right’ and ‘at an angle’ it may be difficult to see the display screen).
 Screen burn-in may be developed in LCD if same screen is displayed (Lights ON all the time etc.)
for long period of time. If continuously operating the instrument for long period of time (under
reference operating condition for 3 months or more), display different screen regularly or turn OFF
the power to prevent screen burn-in.
 Specifications of common mode voltage of all input output terminal except for power supply and
relay output terminal are max. 30V r.m.s., max. 42.4V peak, and max. 60V DC.
1-3-3 Mounting conditions
 Installation altitude is less than 2,000m above the sea level
 Mounting posture longitudinal tilting is less than ±10°lateral tilting is less than ±10°.
1-3-4 Others
 Do not wipe the instrument with an organic solvent (like alcohol).
 To avoid malfunctioning of the instrument, do not use cell phones in its vicinity.
 An obstacle may be created for television and radio sets placed near the instrument.

2-2 Mounting
2-2-1 Panel mounting
Confirm the mounting slot
(1) Mounting slot is located at two locations, the top and the bottom of the instrument.
Assemble into the panel
(1) From terminal board side, put the instrument into the panel cutout angular hole.
For the waterproof specifications, put attached water-proof packing first then put it into the
angular hole.
(2) Prepare attached mounting brackets (2 pieces). Insert mounting claw to the mounting slots (2
locations; top and bottom) and push it into the panel.
Fix the instrument
(1)
Push the mounting brackets into the panel side and fix them.
