NAME
DESCRIPTIONS
1
Case cover
Protects PCB Board and Sensor, etc built in Sensor and Housing from external environmental
change and shock.
2
Mount Holes
It is mounting hole used for fixing the product.
3
LCD display
It displays gas concentration measurements from the sensor and setting modes during parameter
settings in numbers and LED. (Refer to "Front Display Configuration" for detailed description.)
4
Power LED
When the power (DC 24V) is supplied normally, green LED lights on.
5
Trouble LED
Yellow LED lights on when it detects the sensor and flow rate to be fault. It outputs trouble relay
contact signal externally.
6
Alarm1 LED (Red)
When measured gas concentration exceeds set Alarm1 threshold, the LED lights on and relay
contact signal is outputted externally (if it is set).
(Alarm1 level can be set arbitrarily in Alarm setting mode.)
7
Alarm2 LED (Red)
When measured gas concentration exceeds set Alarm2 threshold, the LED lights on and relay
contact signal is outputted externally (if it is set).
(Alarm2 level can be set arbitrarily in Alarm setting mode.)
