6.7 Analog input
By providing the signals from external sensors to the control unit, you can reflect the changes in gas condi-
tions into the measurement result. The analyzer can accept two 4–20 mA DC inputs from a thermometer,
pressure gauge, flowmeter, oxygen analyzer, and/or moisture meter. Wire between each sensor and the ana-
log input terminal of the control unit in reference to “3.2 Wiring diagram”.
Set the parameters of an item with no sensor input to “fixed” and enter a value for each. For items whose
change is negligible, you can set the item to a fixed value.
Be sure to make settings for all the items. Otherwise, the analyzer cannot deliver accurate measurement.
Select “Input Signal” from the “Menu” screen, and press the
key.
6.7.1 Analog input setting: sensor input
The description here is an example when using a thermometer.
Connect the 4-20 mA DC signal from a thermometer to Ch1 or Ch2 of AI terminal.
If you make a setting but there is no signal input, the analyzer emits an “analog input error” alarm.
Select the “Gas Temp.” by the key or the
key. Press the key to move the cur-
sor to “Channel” setting.
