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 varies little, 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
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 Ch1 or Ch2 of the AI terminal of
the control unit. (If an AI expansion board is provided, connect it to either of Ch1 to Ch6.)
When channel setting (4 to 20 mA DC input setting) is performed without sensor input signal to the AI ter-
minal, “Analog input signal error” alarm is output.
Select the “Gas Temp.” by the key or the
key. Press the key to move the cur-
sor to “Channel” setting.
