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.

Warning
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.

(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)
Remarks
(*): 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.

！
Wire to the terminals on the rear of this unit as shown in the following terminal wiring diagrams.
Before carrying out wiring, turn off the power source to this 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.
For complying with CE (IRGMEG2V)
1) Attach the supplied ferrite cores (3 pieces attached as standard), at a place as close as the
terminal board (within 10cm), to bind up each cable to be connected. (→For the details of
attaching ferrite cores, refer to [3.3.1 Enlarge view of the terminal board].)
2) The connection cable should be used indoors and its length should be up to 30m.
