1. Introduction

1.1 General

The infrared multiple-constituents analyzer (hereinafter called “constituent meter”) operator interface/display unit IR-GMEG2 is used in combination with IRMA series constituent meter detector units and can communicate with up to nine (9) detector units. The operator interface/display unit digitally displays constituent values including moisture content and thickness, as well as accessing to parameters of a detector unit. It also provides various functions including communication and calibration curve switching by a contact signal. This manual describes about the operator interface/display unit only. In addition to this manual, refer to a separate instruction manual of [Infrared multiple-constituents analyzer detector unit IRMA], too.

3.1.1-1) For this u n i t n o t i n s t a l l e d o n a p a n e l

(1) Remove the water-proof gaskets fitted in the

locking portions of the internal unit. Hold this unit and then insert the L-shaped part of the supplied pulling-out tool into the lower

locking portion of this unit. 

(2) In this state, press the other side of the tool

down to slide the front panel forward 2 to

3mm and then remove the internal unit. (*) 



(3) After setting the dipswitches, position the

printed circuit boards of the internal unit with the guide rails on the inside of the case and push the internal unit slowly along the guides until it is locked. Make sure to press the water-proof gaskets in the locking portions securely. (Note)

3.1.1-2) For this unit being installed on a panel

For avoiding the risk of electric shock, make sure to turn off the power source to this unit before pulling out the internal unit.

The front panel of this unit complies with IP65 (IEC529). For this compliance, it may be hard to pull

out the internal unit.

！

Warning

For avoiding the risk of electric shock, make sure to turn off the power source to this unit before wiring to the power terminals.

Before carrying out wiring, observe the following precautions.

(1) Terminating wires

Use crimp type lugs covered with the insulation sleeve to prevent wires from dropping off or contacts of wires. (The terminal screws are M3.5.)

(2) Mounting a power switch and a fuse Neither power supply nor fuse is built in this unit. You are required to prepare them separately. 

(3) Power [IRGMEG2]

• The power to IRGMEG2 is universal from 100 to 240V AC but avoid the following powers;

(1) Powers whose voltage fluctuates greatly.

(2) Powers whose waveform distortion is big.

[IRGMEG2V (complying with CE)]

• The power to IRGMEG2 V (complying with CE) is 24V DC (within ±10%).

Ordinarily supply the power to this unit from the power unit IR-WEP.

Caution

The power to IRGMEG2 V (complying with CE) is DC. Observe the following cautions.

1) Ensure correct polarity.

2) The connection with reverse polarity may cause a failure of this unit.

3) Make sure not to supply AC power to this unit. If AC power is supplied by mistake, this unit will be dama

ed.

(4) Noise source

Separate this unit from strong power circuits or powerful noise sources as far as possible. 

5.3 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 (%H2O) 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].

• Computing mode 2: 3-wavelength ratio processing (λ4, 5, 6) in Group 2

• Computing mode 3: 3-wavelength ratio processing (λ7, 8, 9) in Group 3

• Computing mode 4 is multiple regression computation using each wavelength. The number of the wavelengths differs depending on specifications of the detector unit and up to 10 wavelengths are available.

Each computing expression of the calibration curve is shown in the next column.

Note that settable coefficients differ depending on number of wavelengths being used. These coefficients are provided for the quadratic expression correction against a measured value “y”. Assuming that a measured value after the correction be “Y”, we obtain “Y = b2y2+b1y + bo”. These specify measured values at a low limit output and a high limit output on the analog output scaling. The output is scaled to 4mA at the low limit measured value and 20mA at the high limit measured value. A low limit alarm is activated when a measured value is lower than a low limit alarm setpoint. A high limit alarm is activated when a measured value is higher than a high limit alarm setpoint.

If an actual constituent value (moisture content or thickness) does not correspond with a constituent

These coefficients are provided for the quadratic expression correction against a measured value “y”.

Widen the correction range.

Close the distance to the sample. If the lamp is burned out, replace it. Incline or extend the distance to the sample. Set a detector unit number again.

Set two calibration curves setting sample temperature or more.

7. Inspection and maintenance

7.3 Measures against troubles not included with self-diagnosis

If a trouble occurred, take remedial measures referring to the corresponding items of this manual after checking the following points. For the troubles of a detector unit, refer to the separate instruction

manual for [Infrared multiple-constituents analyzer detector unit IRMA].

7.3.1 Measured value remains unchanged.

(1) Is HOLD set to ON? (2) Is PRESET set to ON? (3) Are the calibration curve data correct? (4) Turn off the power once and then turn on it. (5) By using the output checker plate, check if the data displayed in the absorbance display mode

change?

(6) When the data remains unchanged, initialize the RAM. If this phenomenon is not still recovered,

return this unit to CHINO.

7.3.2 Measured value fluctuates.

(1) Is the measuring surface flat? (2) Is the measuring position correct? Make sure that a detector unit does not measure such bottom

face as a conveyor belt, etc. (3) Make sure that any disturbance light is not irradiated onto a measuring surface. (4) Is the smoothing time proper? Certain smoothing time is necessary in stable measurements. (5) Make sure that any noise source does not exist around a detector unit or connection cables.

(6) By using the output checker plate change, check if the data displayed in the absorbance display

mode fluctuate? (7) When the data fluctuates, initialize the RAM. If this phenomenon is not still recovered, return

this unit to CHINO.

7.3.3 Measured value is higher or lower than an actual value.

(1) Is the calibration curve number correct? (2) Are the calibration curve data correct? (3) Is HOLD or PRESET set to ON? (4) Is the measuring position by a detector unit correct?

(5) Is a cover glass surface face of a detector unit clean?

7.4 Maintenance parts

Quantity Replacing interval

Remarks

nonenergized period

7.5 Ram clearing

If an abnormal condition of this unit is not recovered by all means, initialization of the RAM is required.

Caution

(1) Turn on the power by pressing MODE key and CLR key simultaneously. (2) The contents of the RAM are initialized. Set the calibration curve data, etc. again.

For initializing the RAM, make sure to turn off the power source to this unit. The stored contents of the RAM in this unit are initialized. The stored contents (calibration curve data, etc.) of the RAM in a detector unit are not initialized.
