■ Digital Output at Alarm
This function sets the digital output status when an alarm is issued.
It can select whether holding the previous value or setting a fixed value for the
digital output (measurement value display of compact programmable display and
the judgment output Intelligent Monitor AiM) under an alarm operation status
(poor light intensity, or measurement disabled when the target object goes off the
measurement range). When selecting the fixed value, the digital data is displayed
“+999.999999”. When selecting the “Hold the Previous Value”, the hold value is
displayed.
Selecting the fixed value can detect an alarm issued status easily from the
measurement result. Especially this function is effective in that an alarm status
can be confirmed when the measurement value is loaded by performing the
data buffering function.
“Hold Previous value” is set as a default.
· In case of selecting the fixed value, the judgment output is on hold at “HI” by
interlocking with the digital output when an alarm is issued.
· For setting of the digital output at alarm, read “4-4-1 Alarm Setting and
Outputs ” carefully.
