Precautions for Use

1. Installation Precautions

❗ Caution

This instrument is intended to be used under the following environmental conditions (EN61010-1):

• 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 -10 to 50°C (14°F to 122°F) that does not change rapidly, and 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 the vapors of these substances can come into direct contact with the unit.
• When installing this unit within a control panel, please note that ambient temperature of this unit – not the ambient temperature of the control panel – must not exceed 50°C (122°F). Otherwise the life of electronic components (especially electrolytic capacitor) may be shortened.
• Avoid setting this instrument directly on or near flammable material even though the case of this instrument is made of flame-resistant resin.

2. Wiring Precautions

❗ Caution

• Do not leave bits of wire in the instrument, because they could cause a fire and malfunction.
• When wiring, use a crimping pliers and a solderless terminal with an insulation sleeve in which an M3 screw fits.
• The terminal block of this instrument has a structure that is wired from the left side. Be sure to insert the lead wire into the terminal of the instrument from the left side and tighten the terminal screw.
• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw when tightening, the screw or case may be damaged.
• Do not pull or bend the lead wire with the terminal as the base point during or after wiring work. It may cause malfunction.
• This instrument does not have a built-in power switch, circuit breaker and fuse. It is necessary 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)
• When wiring the power supply (24 VDC), do not confuse the polarities.
• 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 the thermocouple and compensation lead wire that match the sensor input specifications of the instrument.
• Use a RTD of 3-conducting wire type that meets 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.
• Separate the input line (thermocouple, RTD, etc.) from the power line and load line.

Operation and Maintenance Precautions

❗ Caution

• It is recommended that auto-tuning (AT) be performed on the trial run.
• Do not touch live terminals. This may cause electrical shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal or cleaning. Working on or touching the terminal with the power switched ON may result in severe injury or death due to electrical shock.
• Use a soft, dry cloth when cleaning the instrument. (Alcohol based substances may tarnish or deface the unit.)
• As the panel part is vulnerable, be careful not to put pressure on, scratch or strike it with a hard object.

Compliance with Safety Standards

❗ Caution

• Use the recommended fuse as described in the instruction manual.
• For analog input:
  • When inputting voltage or current, set the input type to match the input specification.
  • Do not use for measurement of circuits that fall into measurement categories II, III, or IV.
  • Do not use for measurement of objects to which a voltage exceeding 30 Vrms or 60 V DC is applied.
• If the instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may be impaired.
• Use equipment that is reinforced-insulated or double-insulated from the primary power supply for external circuits connected to this instrument.

Overview

This instrument is a control module that can be 2 channels or 4 channels controlled. A multi-point control system can be configured with the control module alone, or via a host computer or PLC. A maximum of 16 instruments can be connected via BUS, and a maximum of 64 points can be controlled. One block connected to BUS is called "1 unit". In addition, a maximum of 16 units can be connected using the communication expansion module QMC1-C and a maximum of 1024 points can be controlled.
