The same procedure can be implemented as for
pressure gauge, thermometer or oxygen analyzer
(O
2
).
6.7.3 Setting of air purge pressure
When the air purge pipe is connected to the pressure sensor, connect its signal (4 to 20mA DC output) to the
analog input of the control unit. Alarm can be issued when the pressure value lower than the set pressure is
detected. Be sure to connect the pressure gauge if the air purge pressure is unstable. If it is not measured in
an environment where high temperature gas can be measured, the analyzer may be damaged.
When the sensor is not provided, select “No” for channel setting. When the channel setting (4 to 20mA DC
input setting) is performed in an environment without sensor input signal, “Analog input signal error” alarm
is output.

Select the channel (CH1 or CH2) connected to AI
terminal by the
key or the
key (se-
lect from CH1 to CH6 when AI expansion board
is connected), and press the
ENT
key.
The relations between channels are as follows;
AI1 = CH1, ......... AI6 = CH6.
