Illustration 3: Operation - Flow Protection
6.3.1.1 Using an Analog 4–20 mA Sensor
Context:
An analog 4–20 mA sensor provides protection and monitoring.
Procedure
1. Connect the sensor to B33, B34.
2. Set parameter 30-5 Flow Sensor Type to Analog.
3. Set parameters 30-6 to 30-8 according to the sensor specifications.
4. Set parameters 31-1 to 31-4, parameter 36-2 Flow Sensor, and parameter 36-7 Low Flow as required.
6.3.1.2 Using a Switch Sensor
Context:
A switch sensor provides protection only.
Procedure
1. Connect the sensor to C23, C24.
2. Set parameter 30-5 Flow Sensor Type to Switch.
3. Set parameters 31-3 to 31-4, parameter 36-2 Flow Sensor, and parameter 36-8 Flow Switch as required.
Parameters 31-1 to 31-2 are not used with a switch sensor.
6.3.1.3 Using a Pulse Sensor
Context:
A pulse sensor provides protection and monitoring.
Procedure
1. Connect the sensor to C23, C24.
2. Set parameter 30-5 Flow Sensor Type to Pulses per Minute or Pulses per Unit.
3. Set parameter 30-6 Flow Units, 30-11 Units per Pulse, and either parameter 30-9 Units per Minute at Max Flow or parameter 30-10 Pulses
per Minute at Max Flow according to the sensor specifications.
4. Set parameters 31-1 to 31-4, and parameter 36-2 Flow Sensor, parameter 36-6 High Flow, and parameter 36-7 Low Flow as required.
