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 Cautions for mounting (1) This instrument is intended to be used under the following

environmental conditions. (IEC61010-1) [OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2]

(2) Use this instrument within the following environment conditions: Allowable ambient temperature: 0 to 50 C Allowable ambient humidity: 20 to 95 % RH

(Absolute humidity: MAX. W. C 29.3 g/m3 dry air at 101.3 kPa) 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.

High voltage equipment: Do not mount within the same panel. Power lines: Separate at least 200 mm. Rotating machinery: Separate as far as possible.

For correct functioning mount this instrument in a horizontal position.

(5) In case this instrument is connected to a supply by means of a permanent connection a switch or circuit-breaker shall be included in the installation. This shall be in close proximity to the equipment and within easy reach of the operator. It shall be marked as the disconnecting device for the equipment.

To prevent electric shock or instrument failure, always turn off the power before mounting or removing the instrument.

WARNING!

3. WIRING

3.1 Cautions for wiring (1) For thermocouple input, use the appropriate compensation wire. (2) For RTD input, use low resistance lead wire with no difference in resistance between the three lead wires. (3) To avoid noise induction, keep input signal wire away from instrument power line, load lines and power lines

of other electric equipment. (4) Signal connected to Voltage input and Current input shall be low voltage defined as “SELV” circuit per IEC 60950-1. (5) When a shielded lead is used, ground the shield as follows to prevent noise generated by both stray

capacitance between the shield and each conductor, and by the shield potential difference with the earth.

To prevent electric shock or instrument failure, do not turn on the power until all wiring is completed. Make sure that the wiring is correct before applying power to the instrument.

To prevent injury to persons, damage to instrument and equipment, a suitable external protection device shall be required.

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.

WARNING!

− 17 −

When signal source is grounded, ground the shield to the signal source side.

When signal source is not grounded, ground the shield to the instrument side.

(6) If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.

Shorten the distance between the twisted power supply wire pitches to achieve the most effective noise reduction. Always install the noise filter on a grounded panel. Minimize the wiring distance between the noise filter output and the instrument power supply terminals to achieve the most effective noise reduction.

Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness of the noise filter.

(7) For wiring, use electric wires conforming to the domestic standard of each country. For power supply wires, use 600 V Polyvinyl chloride insulated wires (JIS C3307). Ground the instrument to the earth through the shortest route possible using an electric wire with a nominal conductor

cross section of 2.0 mm2 or larger. [Grounding resistance: Less than 100 ]

(8) Allow approximately 3 seconds for contact output when the instrument is turned on. Use a delay relay when the output line, is used for an external interlock circuit.

(9) Power supply wiring must be twisted and have a low voltage drop.

(10) This instrument with 24 V power supply is not provided with an overcurrent protection device. For safety install an overcurrent protection device (such as fuse) with adequate breaking capacity close to the instrument. Fuse type: Time-lag fuse (Approved fuse according IEC60127-2 and/or UL248-14) Fuse rating: Rated current: 0.63 A

(11) For an instrument with 24 V power supply input, supply power from "SELV" circuit defined as IEC 60950-1.

(12) A suitable power supply should be considered in end-use equipment. The power supply must be in compliance with a limited-energy circuits (maximum available current of 8 A).

(13) Display accuracy of current transformer (CT) input value at heater break alarm is within 5 % of input value or 2 A, whichever is greater. Therefore, when a heater break alarm is used, set load current flowing through the current transformer (CT) at a value to be sufficiently large.

(14) Use the solderless terminal appropriate to the screw size. Screw size: M3 x 8 Recommended tightening torque: 0.4 Nm [4 kgfcm] Specified solderless terminals: With isolation Applicable wire: Solid/twisted wire of 2 mm2 or less

(15) Make sure that during field wiring parts of conductors cannot come into contact with adjacent conductive parts.
