Note: • Alarm is output only when [F10:DO Function] is set to “Alarm Output.”
• The operation when “Open (Off) Act” is set for [F11:DO Active Mode] is shown in above table.
*: The output value is performed in accordance with the setting of the burnout switch. For information about this switch, see Section 10.3.1.

Note: • larm is output only when F10: DO Function is set to “Alarm Output.”
• The operation when “Open (Off) Act” is set for F11: DO Active Mode is shown in above table.
• 4-20mA output upon the occurrence of an alarm will be fixed at the value selected with G25: 4-20mA Process Alarm.
*: Although outputs are continuous, output values are not guaranteed.
