6.7 Analog input
Makes a setting of the analog input related to the measured gas conditions such as gas temperature. Input the
sensor signal to the analog input terminal of the control unit, and the measured gas conditions can be cali-
brated. The sensors to be connected to the analog input terminal are “Thermometer”, “Pressure gauge”,
“Flow meter”, “Oxygen analyzer (O
2
)” or “Moisture meter (H
2
O)” with 4 to 20mA DC output. For connect-
ing the sensor, refer to “3.2 Input/output terminal of control unit”.
If the calibration is not performed, the measurement value may not be output correctly.
When the measured gas conditions are invariant, calibration can be performed with the fixed value at the
fixed value setting.
2 channels are selected for the analog input terminal. The channel can be increased up to 6 by mounting the
additional board. Set the measured gas conditions with no sensor input to the fixed value setting, and enter
the fixed value.
Select “Input Signal” from the “Menu” screen, and press the
ENT
key.

6.7.1 Setting of 4 to 20mA DC Input (in case of gas tempera-
ture)
The sensor signal of the thermometer (4 to 20mA output) is connected to AI1 or AI2 of the AI terminal of the
control unit. (If an AI expansion board is provided, connect it to either of AI1 to AI6.)
When channel setting (CH1 to CH6 setting) is performed without sensor input signal to the AI terminal,
“Analog input signal error” alarm is output.
