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

3.1 Setting dipswitches
Set internal dispswitches before installing this unit.
3.1.1 How to pull out the internal unit.
3.1.1-1) For this unit not installed on a panel
(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
(1) Remove the water-proof gaskets fitted in the
locking portions of the internal unit. Insert
the L-shaped part of the supplied pulling-out
tool for the internal unit into the locking
portion on the lower side 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 the locking portion is activated. Make
sure to press the water-proof gaskets in the
locking portions securely. (Note)
3. Installation and connections
！
The front panel of this unit complies with IP65
(IEC529). For this compliance, it may be hard to pull
out the internal unit.
(Note)
When this unit is used in the state that the
locking portion is not activated, it may cause
display fluctuation by contact failure of
terminal metals. In addition, the
effectiveness of water-proofing may become
im
p
aired.
(*): Ordinarily the internal unit can be pulled out by only loosening the lower
locking portion of this unit. However, if it is hard to remove it, loosen the upper
locking portion, too.
Warning
For avoiding the risk of electric shock, make sure to turn off the power source to
this unit before
p
ullin
g
out the internal unit.

3.4 Cautions on connections
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.
(4) Noise source
Separate this unit from strong power circuits or powerful noise sources as far as possible.
！
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

5.1 Confirmation before operation
Check the following three points before turning on the power.
1) Have the dipswitches been set? (Refer to [3.1 Setting dipswitches].)
2) Are all of connections correct? (Refer to [3.3 Connections])
3) In the multiple-detector-units connection, have detector unit numbers been set?
(Refer to the separate instruction manual for [Infrared multiple-constituents analyzer detector unit
IRMA].)
5.2 Setting detector unit numbers
When the power to this unit is turned on, data
measured by the constituent meter with the detector
unit number being indicated in “HEAD” will be
displayed.
The following procedure is for changing a detector
unit number.
(1) Press HEAD key to enter into the detector unit
number setting mode with the setting lamp
“HEAD” lit.
(2) Press the numeric keys 1 to 9 to enter a detector
unit number.
(3) By pressing ENT key, the data measured by the
constituent meter with the changed detector unit
number will be displayed. The calibration curve
number and the constituent value displayed this
time are under the conditions set in the changed
constituent meter. (Time constant, decimal places
of constituent values displayed, etc.)
Turn on the power to this unit concurrently with or after turning on the power to
detector units.
If the power to this unit is turned on before turning on detector units, this unit can
not recognize the detector units and will display the error code Er18 (detector unit
number error
)

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].
