INSTRUCTION MANUAL
Thank you for purchasing this RKC product. In order to achieve maximum performance
and ensure proper operation of your new instrument, carefully read all the instructions in
this manual. Please place the manual in a convenient location for easy reference.
• To prevent injury to persons, damage to instrument and equipment,
a suitable external protection device shall be required.
• All wiring must be completed before power is turned on to prevent
electric shock, fire or damage to instrument and equipment.
• This instrument must be used in accordance with the specifications
to prevent fire or damage to instrument and equipment.
• This instrument is not intended for use in locations subject to
flammable or explosive gases.
• Do not touch high-voltage connections such as power supply
terminals, etc. to avoid electric shock.
• RKC is not responsible if this instrument is repaired, modified or
disassembled by other
Malfunction can occur and warranty is void under these conditions.
CAUTION
•
This product is intended for use with industrial machines, test and
measuring equipment. (It is not designed for use with medical equipment
and nuclear energy.)
•
This is a Class A instrument. In a domestic environment, this instrument
may cause radio interference, in which case the user may be required to
take additional measures.
•
This instrument is protected from electric shock by reinforced insulation.
Provide reinforced insulation between the wire for the input signal and
the wires for instrument power supply, source of power and loads.
•
Be sure to provide an appropriate surge control circuit respectively for
the following:
- If input/output or signal lines within the building are longer than 30 meters.
- If input/output or signal lines leave the building, regardless the length.
•
This instrument is designed for installation in an enclosed instrumentation
panel. All high-voltage connections such as power supply terminals must be
enclosed in the instrumentation panel to avoid electric shock by operating
personnel.
•
All precautions described in this manual should be taken to avoid
damage to the instrument or equipment.
•
All wiring must be in accordance with local codes and regulations.
•
All wiring must be completed before power is turned on to prevent
electric shock, instrument failure, or incorrect action. The power must be
turned off before repairing work for input break and output failure
including replacement of sensor, contactor or SSR, and all wiring must
be completed before power is turned on again.
•
To prevent instrument damage as a result of failure, protect the power line and
the input/output lines from high currents with a suitable overcurrent protection
device with adequate breaking capacity such as a fuse, circuit breaker, etc.
•
Prevent metal fragments or lead wire scraps from falling inside
instrument case to avoid electric shock, fire or malfunction.
•
Tighten each terminal screw to the specified torque found in the manual
to avoid electric shock, fire or malfunction.
•
For proper operation of this instrument, provide adequate ventilation for
heat dispensation.
•
Do not connect wires to unused terminals as this will interfere with
proper operation of the instrument.
•
Turn off the power supply before cleaning the instrument.
•
Do not use a volatile solvent such as paint thinner to clean the
instrument. Deformation or discoloration will occur. Use a soft, dry cloth
to remove stains from the instrument.
•
To avoid damage to instrument display, do not rub with an abrasive
material or push front panel with a hard object.
•
When high alarm with hold action is used for Alarm function, alarm does
not turn on while hold action is in operation. Take measures to prevent
overheating which may occur if the control device fails.

2. MOUNTING
2.1 Mounting Cautions
(1) This instrument is intended to be used under the following environmental
conditions. ( IEC61010-1 )
[OVERVOLTAGE CATEGORY II,
(2) Use this instrument within the following environment conditions:
• Allowable ambient temperature:
• Allowable ambient humidity:
(Absolute humidity: MAX. W. C 29.3 g/m
•
Installation environment conditions: Indoor use, Altitude up to 2000 m
(3) Avoid the following conditions when selecting the mounting location:
• Rapid changes in ambient temperature which may cause condensation.
• Corrosive or inflammable gases.
• Direct vibration or shock to the mainframe.
• Water, oil, chemicals, vapor or steam splashes.
• Excessive dust, salt or iron particles.
• Excessive induction noise, static electricity, magnetic fields or noise.
• Direct air flow from an air conditioner.
• Exposure to direct sunlight.
• Excessive heat accumulation.
(4) Mount this instrument in the panel considering the following conditions:
• Provide adequate ventilation space so that heat does not build up.
• Do not mount this instrument directly above equipment that generates large
amount of heat (heaters, transformers, semi-conductor functional devices,
large-wattage resistors.)
• If the ambient temperature rises above 50 °C, cool this instrument with a forced air
fan, cooler, etc. Cooled air should not blow directly on this instrument.
• In order to improve safety and the immunity to withstand noise, mount this
instrument as far away as possible from high voltage equipment, power lines, and
rotating machinery.
