Read only. Used to view the current state of the High Flowrate Alarm.
2.8.10. Low Flowrate Alarm
Available only on LUT440 (OCM model).
Reported when the OCM flowrate is within a user-defined range (see
2.8.10.2.Low Flowrate Value ON
and
2.8.10.3.Low Flowrate Value OFF
).
2.8.10.1. Enable
Enables/disables Low Flowrate Alarm.
2.8.10.2. Low Flowrate Value ON
Sets the flowrate value (defined in 2.15.3.7.Flowrate Units) at which the Low
Flowrate Alarm will activate.
2.8.10.3. Low Flowrate Value OFF
Sets the material level (defined in 2.15.3.7.Flowrate Units) at which the Low
Flowrate Alarm will de-activate.
2.8.10.4. Assigned Relay
Determines which relay (if any) will be activated when the Low Flowrate
Alarm activates.
2.8.10.5. Alarm State
Read only. Used to view the current state of the Low Flowrate Alarm.
2.8.11. Relay Logic
Relay contact operation is NORMALLY CLOSED for alarms and NORMALLY
OPEN for controls.
By default an alarm contact is Normally Closed. When an alarm activates, the
corresponding relay coil is de-energized. By setting this parameter to Normally
Open, the relay coil will be energized when an alarm assigned to the relay
activates.
