Wet/Dry Setting; Setting Of Range Switching - Fuji Electric FE ZSS Instruction Manual

Input switching of the remote instantaneous/average value (DI2 terminal)
Apply rectangular waveform (pulse width: 2.0 sec or more, pulse interval: 2.0 sec or more) to the input
terminal of remote average value to switch the instantaneous value and the average value.
If the previous measured value is set as instantaneous value, and O
value, the previous measured value becomes the average value, and the O
instantaneous value after pulse input.

6.6.2 Wet/dry setting

Make a setting of "Wet" or "Dry" for each measurable component. The setting is reflected on the display on
the "Measurement" screen or external output such as analog output.
O conversion value can be arbitrarily selected even if the previous measurement value is set to wet (or dry).

The analyzer is available in the "Wet" environment. When "Dry" is set, H
screen is required. When the moisture meter is provided, input its output signal (4 to 20mA DC output) to the
analog input of the control unit, and set the range, referring to "6.7.1 Setting of 4 to 20mA DC Input (in case
of gas temperature)". When the moisture meter is not provided, the input switching on the "Analog Input"
screen is set to "Fixed", and the dry conversion is performed at the moisture value.
Wet can be converted to Dry using the following expression.
Measurement value (dry) = Measurement value (wet) × 100/ (100 – moisture content (%))

6.6.3 Setting of range switching

In case of 1 range specification, "Range1" can only be displayed, so the setting is not necessary.
In case of 2 range specification, select one from the following 4 methods.
"Auto" : Range 1 and Range 2 are automatically switched. When the measurement value is more
than 90% of Range 1, it is switched to Range 2. When the measurement value is less
than 80% of Range 1, Range 2 is switched to Range 1.
"Range1" : Range 1 is fixed.
"Range2" : Range 2 is fixed.
"Remote" : Range 1 and Range 2 are switched by the analog input (DI4).
