Manuals
Thank you for purchasing our JIR-301-M, Digital Indicator. This manual contains instructions for the mounting, functions, operations and notes when operating theJIR-301-M. To ensure safe and correct use, thoroughly read and understand this manual before using this instrument. To prevent accidents arising from the misuseof this instrument, please ensure the operator receives this manual.

Safety Precautions (Be sure to read these precautions before using
our products.)
The safety precautions are classified into 2 categories: “Warning” and “Caution”.
Warning: Procedures which may lead to dangerous conditions and cause death orserious injury, if not carried out properly.
Caution: Procedures which may lead to dangerous conditions and cause superficial
to medium injury or physical damage or may degrade or damage the product,
if not carried out properly.

Warning• To prevent an electric shock or fire, only Shinko or other qualified service personnel may
handle the inner assembly.
• To prevent an electric shock, fire or damage to the instrument, parts replacement may
only be undertaken by Shinko or other qualified service personnel.

SAFETY PRECAUTIONS• To ensure safe and correct use, thoroughly read and understand this manual before
using this instrument.
• This instrument is intended to be used for industrial machinery, machine tools andmeasuring equipment. Verify correct usage after purpose-of-use consultation with ouragency or main office. (Never use this instrument for medical purposes with whichhuman lives are involved.)• External protection devices such as protective equipment against excessive temperaturerise, etc. must be installed, as malfunction of this product could result in serious damage
to the system or injury to personnel. Proper periodic maintenance is also required.
• This instrument must be used under the conditions and environment described in thismanual. Shinko Technos Co., Ltd. does not accept liability for any injury, loss of life ordamage occurring due to the instrument being used under conditions not otherwise
stated in this manual.

Mounting Precautions
This instrument is intended to be used under the following environmental conditions(IEC61010-1)]: Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 )(No icing)• An ambient non-condensing humidity of 35 to 85 %RH• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or where the vapors of these substances can come into directcontact with the unit
• Please note that the ambient temperature of this unit – not the ambient temperature of thecontrol panel – must not exceed 50 (122 ) if mounted through the face of a control panel,otherwise the life of electronic components (especially electrolytic capacitors) may be
shortened.

Wiring Precautions• Do not leave wire remnants in the instrument, as they could cause a fire or malfunction.
• Use the solderless terminal with an insulation sleeve in which the M3 screw fits when wiring
the instrument.
• The terminal block of the JIR-301-M is designed to be wired from the upper side. Thelead wire must be inserted from the upper side of the terminal, and fastened by theterminal screw.
• Tighten the terminal screw using the specified torque. If excessive force is applied to thescrew when tightening, the terminal screw or case may be damaged.
(0.63 N•m of torque is recommended.)• Do not pull or bend the lead wire on the terminal side when wiring or after wiring, as it could
cause malfunction.
• This instrument does not have a built-in power switch, circuit breaker and fuse. It isnecessary to install a power switch, circuit breaker and fuse near the instrument.
(Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• For the grounding wire, use a thick wire (1.25 - 2.0 mm2).
• For a 24 V AC/DC power source, ensure polarity is correct when using direct current (DC).
• Do not apply a commercial power source to the sensor which is connected to the input
terminal nor allow the power source to come into contact with the sensor.
• Use a thermocouple and compensating lead wire according to the sensor input
specifications of this instrument.
• Use the 3-wire RTD according to the sensor input specifications of this instrument.
• When using a relay contact output type, externally use a relay according to the capacity of
the load to protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC power sources orload wires.

Caution with Respect to Export Trade Control Ordinance

To avoid this instrument from being used as a component in, or as being utilized in themanufacture of weapons of mass destruction (i.e. military applications, military equipment,etc.), please investigate the end users and the final use of this instrument. In the case ofresale, ensure that this instrument is not illegally exported.
