General Operation
Fail-safe Fault Alarm
Activates an alarm when a fault that has caused a fail-safe condition is present.
Example: Setting a Fail-safe Fault Alarm
To assign a fail-safe fault alarm to Relay 3 do the following:
1. Enable the Fail-safe Fault Alarm (set
2.8.8.1. Enable
= Enabled)
2. Set
2.8.8.2. Assigned Relay
to Relay 3.
Use
2.8.8.3. Alarm State
to view the current state of the Fail-safe Alarm.
Flowrate
Flowrate alarms are available on LUT440 (OCM) model only. They can activate an alarm if
the OCM flowrate is above or below a given setpoint.
Example: Setting a High Flowrate Alarm
To assign Relay 3 to a high flowrate alarm that activates when the flowrate rises above
10 l/s:
1. Enable the High Flowrate Alarm (set
2.8.9.1. Enable
= Enabled).
2. Set
2.8.9.2. High Flowrate Value ON
= 10
3. Set
2.8.9.3. High Flowrate Value OFF
= 8
4. Set
2.8.9.4. Assigned Relay
to Relay 3
Example: Setting a Low Flowrate Alarm
To assign Relay 3 to a low level alarm that activates when the flowrate falls below 2 l/s:
1. Enable the Low Flowrate Alarm (set
2.8.10.1. Enable
= Enabled)
2. Set
2.8.10.2. Low Flowrate Value ON
= 2
3. Set
2.8.10.3. Low Flowrate Value OFF
= 4
4. Set
2.8.10.4. Assigned Relay
to Relay 3
Pump Control
The SITRANS LUT400 has the pump control functionality to solve nearly any water /
wastewater application.
