Burn
Select the designated output in case of a fault from among Off, Low, and High. See “10.3 Error
conguration” to set the output.
Off: Output depends on the measured value.
Low: Output is xed to 3.6 mA (when None is set in Communication setup)
Output is xed to 3.9 mA (when HART or PH201G is selected in Communication setup)
High: Output is xed to 22.0 mA.
Damping time
This is the time taken for a response to a step input change to reach 90% of the nal value
(attenuation time). Set this time in sec.
l Simulate
When this function is selected, an output of the instrument will be a xed current value set in % of
the output span. The output span range is -2.5% to 112.5% (3.6 mA to 22.0 mA).
When “Simulate” is selected, regardless of hold setting, the output is always simulated value.
n Congure Hold
On the Congure Hold, settings are performed to hold of the mA output at a preset value. (Refer
to the section 11.7.) This is enabled only if “mA” is “Output.”
During the Commissioning or the Quick Setup, the mA output is automatically held. The preset
value depends on a setting on the “Last or xed”.
“Last”: The preset value is a value measured just before hold condition.
“Fixed”: The preset value is a value set in the “Fixed value mA”.
When the “Fixed” is selected, set a mA value in the “Fixed value mA”.
Selection on the “Hold during Calibration” decides to activate or deactivate the hold function
automatically during calibration.
“Enabled”: Activation of the automatic hold function
“Disabled”: No automatic hold function
10.3 Error conguration
In Error conguration, congure the statuses of various error causes.
This allows the system to notify the user of the occurrence of an error according to the status
categories in the Error conguration.
Select a status category from among Off, Warn. (Warning), and Fault.
“Fault” automatically performs burn-out. When Burn has been set to Off (10.2 Output setup), only
the error message is displayed.
“Warn.” displays an error message.
When selecting PH201G in the communication setting, make sure that the “Fail contact” setting
is appropriate.
The settable causes of errors are determined based on the settings of the Sensor setup and
Measurement setup, and a status category is set to the causes displayed in the Errors 1/3 to 3/3
screens.
