Autonics KRN50 Series 50 mm Hybrid Recorder Instruction Manual

KRN50 Series 50 mm Hybrid Recorder

Product Information

The 50 mm Hybrid Recorder KRN50 Series is a device designed for measuring and recording various types of inputs, such as temperature sensors (TC, RTD), and analogue inputs (voltage, current). It features a fail-safe device that must be installed when using the unit with machinery that may cause serious injury or substantial economic loss. The device also has options for alarm outputs and option outputs for RS485 communication output. The power supply can either be through 100-240 VAC 50/60 Hz or 24 VDC.
The device is equipped with a Lithium battery that should not be disassembled or burned.

Safety Considerations

• Always install the fail-safe device when using the unit with machinery that may cause serious injury or substantial economic loss.
• Do not connect, repair, or inspect the unit while connected to a power source.
• Check connections before wiring.
• Do not touch the unit during or after operation for a while.
• Do not use the unit in the place where flammable/explosive/corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact or salinity may be present.
• Do not disassemble or modify the unit.
• Since Lithium battery is embedded in the product, do not disassemble or burn the unit.

Product Usage Instructions

1. Refer to the manuals and follow the safety considerations in the manuals for proper use of the product.
2. Use the unit within the rated specifications to avoid fire or product damage.
3. Clean the unit using a dry cloth and avoid using water or organic solvent to prevent fire or electric shock.
4. Keep the product away from metal chip, dust, and wire residue that can flow into the unit, causing fire or product damage.
5. Do not use the load beyond the rated switching capacity contact to avoid fire, relay broken, contact melt, insulation failure, or contact failure.
6. When connecting the temperature sensor (TC, RTD) or analogue input (voltage, current) as input to the universal input card, set the jumper pin to the correct place for the connected input type.
   If the jumper pin is placed improperly, it may result in product damage or malfunction.

• Symbol indicates caution due to special circumstances in which hazards may occur.

Warning: Failure to follow instructions may result in serious injury or death.

1. Fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss. (e.g. nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, etc.)
   Failure to follow this instruction may result in personal injury, economic loss or fire.

2. Do not connect, repair, or inspect the unit while connected to a power source. Failure to follow this instruction may result in fire or electric shock.
   Check ‘Connections’ before wiring.
   Failure to follow this instruction may result in fire.

3. Do not touch the unit during or after operation for a while.
   Failure to follow this instruction may result in burn or electric shock due to high temperature of the surface.

4. Do not use the unit in the place where flammable/explosive/corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact or salinity may be present. Failure to follow this instruction may result in explosion or fire.

5. Install on the device panel, and ground to the F.G. terminal separately.
   When connecting the F.G. terminal, use AWG16 (1.25 mm²) or over.

   Failure to follow this instruction may result in fire.

Caution: Failure to follow instructions may result in injury or product damage.

1. Use the unit within the rated specifications.
   Failure to follow this instruction may result in fire or product damage.

2. Use a dry cloth to clean the unit, and do not use water or organic solvent.
   Failure to follow this instruction may result in fire or electric shock.

3. Keep the product away from metal chip, dust, and wire residue which flow into the unit.
   Failure to follow this instruction may result in fire or product damage.

4. When connecting the power input or measurement input, use AWG20 (0.50 mm²) cable or over, and tighten the terminal screw with a tightening torque of 0.74 N·m to 0.90 N·m.
   Failure to follow this instruction may result in fire or malfunction due to contact failure.

5. Do not use the load beyond rated switching capacity contact.
   Failure to follow this instruction may result in fire, relay broken, contact melt, insulation failure or contact failure.

6. When connecting the temperature sensor (TC, RTD) or analogue input (voltage, current) as input to the universal input card, set the jumper pin to the correct place for the connected input type.
   If the jumper pin is placed improperly, it may result in product damage or malfunction.

Cautions during Use

• Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
• Install a surge absorber at each end of inductive load coil when controlling high-capacity power  relay or inductive load (e.g. magnet).
• 24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.
• Check the polarity of the terminals before wiring the temperature sensor. For RTD temperature sensor, wire it as 3-wire type, using cables in same thickness and length. For thermocouple (CT) temperature sensor, use the designated compensation wire for extending wire.
• Keep away from high voltage lines or power lines to prevent inductive noise. In case installing power line and input signal line closely, use line filter or varistor at power line and shielded wire at input signal line. Do not use near the equipment which generates strong magnetic force or high frequency noise.
• This unit may be used in the following environments.
  • Indoors (in the environment condition rated in ‘Specifications’)
  • Altitude max. 2,000 m
  • Pollution degree 2
  • Installation category II
