data sheet (see chapter 15). The operating and maintenance instructions of the sensor to be con-
nected should also be noted.
Notes for the Operation With Catalytic Combustion Sensors
Sensor poisons
For the safe operation of the catalytic combustion sensors it must be made sure that in the envi-
ronmental air no substances and gases which damage or poison the sensor appear. These sen-
sor poisons are a. o. Silicone, Silane compounds, Hydrogen Sulfide, Sulfur compounds. In the
case of doubt a MSA-Auer employee must be contacted to judge on the spot the possible appear-
ance of sensor poisons and suggest alternative measurement procedures.
Oxygen Concentration
Catalytic combustions sensors operation is only possible at an O2 concentration of above
10 Vol.%. At O2 concentrations above 22 Vol.%, the EX approval for remote measuring heads be-
comes invalid.
Measuring Free
Before the installation of the sensors it must be made sure that the environmental atmosphere is
free of combustible gases (e.g. by check with hand-held test instruments). The unambiguity oth-
erwise cannot be ensured to the measuring value indication at the SUPREMA.
Note for Operation with Active Sensors (0/4 ... 20 mA)
At use of MCI modules Order No 10021029 and 10041567: The requirements of line control ac-
cording to EN 61779-1 are not met with 3-wire operation in case of short-circuit of the signal output
of the remote measuring head against GND.
This note is invalid if using the MCI modules Order No 10043997 and 10044020. This modules
are without any qualification operative.
Overview of the Terminal Assignment
In the following, an overview is presented of the assignment of the terminals. If the sensors are to
be connected directly to the rack, the MAT module is to be used. For remote connection (installa-
tion on a mounting rail), the MAT TS module (maximum conductor cross section, 1.5 mm
2
; sen-
sors can be electrically isolated individually) or the MGT 40 TS module (maximum conductor cross
section, 2.5 mm
2
; 8 sensors per module, can be isolated electrically only as a group) can be used.
The remote modules are connected to the MUT module on the rack by the associated ribbon ca-
ble.
