3. Output terminals

(1) Use the output terminals within the rating range. Application of a load out of the rating range may cause breakdown, significant degradation, or malfunction to the unit.

About analog output

This unit is designed for use with multiple-constituents analyzer detector units’ connection and can connect plural constituent meter detector units.

The detector unit to provide output then is determined by dipswitch settings as below.

Refer to [4-1-2. Setting dipswitches] for dipswitch setting.

High and low limit outputs in the calibration curve setting are used for the output scale (paired with the calibration curve number).

Detector unit with a 1 constituent specification

Detector unit with a 2 or more constituents specification

OUT 1 Constituent 1 of the detector unit number 1 Constituent 1 of the detector unit number 1



(2) Dipswitch 1: ON, 4: OFF (Multiple-detector-unit connection)

High and low limit outputs in the calibration curve setting are used for the output scale (paired with the calibration curve number).

2 or more detector units connected

OUT 1 Constituent 1 of the detector unit number 1



(3) Dipswitch 1: OFF, 4: ON (Single-detector-unit connection)

4. Alarm terminals

(1) Use the alarm terminal within the rating range. Application of a load out of the rating range may cause breakdown, significant degradation, or malfunction to the unit.

(2) Make sure to apply a load to the alarm terminal via a buffer relay. Also, a contact protection element must be provided on the coil side of the buffer relay to protect the contact of the unit’s internal relay and to reduce noise.

Capacitor: 0.01 μF (rating about 1 kV)

Resistance: 100 to 150 Ω (rating about 1 w)

！

Caution

(1) Connecting a power source out of the rating range may cause breakdown,

significant degradation, or malfunction to the unit.

(2) Analog and contact outputs may have a defective result due to malfunction,

breakdown, and sensor failure. Make safety provisions on the final product

side, if necessary.

4-5-5. Cautions on connections

！

Warning

Make sure to read and understand this part to avoid the risk of serious accidents.

1. Ask specialists for wiring.

Wiring must be carried out by a specialist with basic knowledge of instrumentation and experiences in it.

2. Set a terminal cover.

To secure safety, after wiring, provide a measure so that the unit terminals are not touched directly.

3. Separate the unit from strong power circuits or noise sources.

To avoid any negative effect by noise, do not install the unit in the vicinity of noise generating instruments (e.g. magnetic relay, motor, thyristor regulator, and inverter). Also, do not set the cables of this unit and those from the noise generating instruments in a same duct. Make sure to separate them.

Take noise reduction measures, if necessary.

4. Use care with ground terminal wiring.

For overall reliability of the final product, proper grounding (earth) is very important. It is generally recommended that each instrument is ground by single-point grounding. In multiple-point grounding, they become prone to be negatively impacted by noise. Use special care with the grounding path.

5. Separate the unit from heat sources.

To avoid any negative effect by high temperature, do not install the unit in the vicinity of heat sources. With a heat source close to it, the unit may cause measurement errors and eventually its life may shorten significantly.

Pay attention to ambient temperature of the unit.

Also, avoid windy locations or sudden temperature changes which trigger measurement errors of the unit.

6. Unassigned terminals

Do not connect anything to unassigned terminals. It may cause a failure of the unit.

7. Measures against erroneous output at the time of power on

After turning on the power source, output-related signals may be generated momentarily before the unit starts operating normally. Take measures in external circuits, if necessary.

6. Operation

6-1. Confirmation before operation

Check the following three points before turning on the power.

1) Have the dipswitches been set? (Refer to [4-1. Setting dipswitches].)

6-4. Setting calibration curves

Output characteristics of detector units depend upon measuring objects. It may also change according to process conditions or constituent measuring conditions of samples.

Accordingly, for accurate measurements, it is required to perform beforehand sample tests of each object and obtain, for moisture measurements, a relationship (This is called as a calibration curve.) between moisture contents (%H

2

O) obtained by a drying method or other measuring methods and absorbance “x” measured by a detector unit] or, for thickness measurements, a relationship (This is called as a calibration curve.) between thickness (μm) obtained by a micrometer or other measuring methods and absorbance “x” measured by a detector unit].

Reference

This paragraph describes the setting method of calibration curve data, assuming that calibration curves have been already created.

When the calibration curves have not been created yet, refer to the paragraph [Sample preparation] in the separate instruction manual of the detector unit IRMA□□□□□□ being connected.

6-5. Sample temperature correction function

6-5-1. General

When a calibration curve changes depending on the sample temperature Ts, this function enables to switch the calibration curve to other one corresponding to the sample temperature measured.

For the input of the sample temperature, a radiation thermometer or a temperature/voltage converter with the output of

4 to 20mADC can be used.

By utilizing this function, 10 calibration curves in one group (9 calibration curves only in the group 10) can be switched corresponding to the sample temperature Ts.

99 calibration curves are available and up to 10 groups can be set accordingly.

7. Creating calibration curves

Output characteristics of detector units depend upon measuring objects. It may also change according to process conditions or constituent measuring conditions of samples.

Accordingly, for accurate measurements of constituants such as water, it is required to perform beforehand sample tests of each object and obtain, for moisture measurements, a relationship (This is called as a calibration curve.) between moisture contents (%H

2

O) obtained by a drying method or other measuring methods and absorbance “x” measured by a detector unit] or, for thickness measurements, a relationship (This is called as a calibration curve.) between thickness

(μm) obtained by a micrometer or other measuring methods and absorbance “x” measured by a detector unit].

・

Make sure that any disturbance light is not irradiated onto a measuring surface.

・ Is the smoothing time proper? Certain smoothing time is necessary in stable measurements.

・

Make sure that any noise source does not exist around a detector unit or connection cables.
