Example of high alarm setup
Given below is an example of setting up the alarm for high alarm.
●
Setup example (where "alarm hysteresis" and "alarm immunity time" are involved.)
・
Alarm conditions: When the following condition continues beyond the alarm immunity time.
Instant flowrate
≧
Alarm setpoint
・
Alarm cancel conditions: Instant flowrate < Alarm setpoint - Alarm hysteresis
Stays off
Alarm 2 setpoint
Flowrate
→
[L
/min(normal)]
Alarm 2 hysteresis

Within alarm immunity time →
Beyond alarm immunity time →
NOTES: If alarm status (lower digit) is set to "o", the "ON" and "OFF" of alarm output become the
opposite states shown in the above figure.

Setup example (where "alarm hysteresis" exists and "alarm immunity time" is set to "0".)
