Powering up and use
4.1
Powering up
•
The sensor turns on when connected to a power
supply.
•
If the sensor has a display, the green LED will be lit
(ref. 2) and a value will appear on the display screen
(ref. 1).

Figure 14: CTX 300 SC main circuit board.
In case of a problem with CTX 300 SC, verify that the maintenance switch (ref. 1), located on the
main circuit, is in the
MES (measure) position.
4.2
4-20 mA analog output
For
CTX 300 sensors, the 4-20 mA output current is proportional to the gas level.
The various states of the 4-20 mA output are:
•
≤
1 mA to indicate a fault.
•
Between 4 and 20 mA for measurement values.
•
≥ 20 mA if levels exceed measurement range.
