Description
Alarm
setpoint
Alarm setpoint.
Beyond this setpoint, an alarmed condition takes place. (During
the time of alarm dead zone, alarm output and LED indication
remain inactive, however).
Set the flowrate to activate an alarm.
Setpoint reads in L/min (normal).
Alarm
hysteresis
Alarm hysteresis.
If flowrate fluctuation is excessive, causing frequent alarm ON-
OFF trips, select a larger value.
Setpoint reads in L/min (normal).
Alarm
status
Alarm I status setpoint.
By selecting either code of the following to the upper digit, you
can set up the type of errors to be identified.
H: High alarm L: Low alarm
By setting either code of the following, you can set up the sta-
tus of open collector output in an error.
o: OFF in an error S: ON in an error
Alarm
setpoint
Alarm setpoint.
The functions remain the same as Alarm setpoint.
Alarm
hysteresis
Alarm hysteresis.
The functions remain the same as Alarm I hysteresis.
Alarm
status
Alarm detailed status setting.
The functions remain the same as alarm status.
Low alarm
dead zone
The lower limit to activate an alarm. Below this flowrate, alarm
remains inoperative even if alarm conditions are met.
Reads in L/min (normal).
Alarm dead
duration
Delay time of identifying an alarm. Any alarm condition does
not activate an alarm at once; only after the expiration of this
duration.
Read in seconds.
