Chapter 3 Starting and Stopping this Device
3-1-2 Settings Confirmation
Confirm that the settings required for operation are set correctly.
(1) Tag Number Setting
Confirm that it is the tag number specified in advance. When changing the tag number, confirm
that the specifications for this device are compatible with the installation location.
(2) Output Format Settings
Warning
In order to detach the terminal block with integrated indicator devices, refer to Chapter
4 and exercise sufficient care when opening the case cover. When using the product in
a hazardous area, do not open its case cover. There is a risk of explosion, etc.
Caution
Take sufficient care when specifying the output formats. In particular, if the fail-safe
setting and the hardware write protection setting are specified incorrectly, the device
can enter a dangerous operating state.
Take sufficient care when when changing the hardware write protection setting.
Removing write protection makes it possible for the settings of this device to be changed
erroneously, and as a result, for the device to enter a dangerous operating state.
• Output format
Enables selection of “Linear / Square Root.”
• Cutoff
Output will be cut off when the flow rate is low. Sets the threshold value for that cutoff.
• Dropout
Selects whether to make the output zero or make it linear during output cutoff.
• Flow rate mode
Selects whether to take the square root in the positive direction only or in both directions.
• Burnout direction
Indicates the behavior of the output during major failures. Specified using switch S2 in Figure 3-2.
Hi (H side): Output swings to the high limit (21.6 mA).
Low (L side): Output swings to the low limit (3.6 mA).
If optional specifications (special burnout) are selected, the low limit
will be 3.2 mA.
None:
Output continues.
• Burnout On/Off
Enables selection of burnout On/Off. Specified using switch S3 in Figure 3-2.
On (E side): Device behaves according to burnout direction setting.
Off (D side): Burnout direction setting is ignored, and the device continues to
output measurement results.
• Output limit setting
Except during burnout, the output current can be restricted to limit values which set the output
current range.
