Configuration

It’s important to do proper sensor configuration. The valve internally calculates in absolute values, so the valve needs to know what sensors are connected.

 

The CPA window shows a good overview of the sensor settings

SensorConfiguration

 

Parameter

Description

Available

Set to True if a sensor is connected

Enable

Set to True if the sensor signal is used for pressure control

Input Source

Analog

 

Digital

 

Simulation

Sensor has an analog voltage interface and is direct connected to the valve.

Sensor and Valve have EtherCAT interface and is connected to the EtherCAT bus

Testing the valve and pressure control without being connected to the system

Range.Scale

Select type of the sensor signal

Linear

Logarithmic

Most gauges are linear type gauges.

Range.Data Unit

Set the pressure data unit of the gauge:

Pa, kPa, bar, mbar, Torr, mTorr, psia, psig

Range.Upper Limit Data Value

Range.Lower Limit Data Value

Set the upper limit and lower limit of the gauge in the unit of Range.Data Unit

Example for a 250mTorr linear sensor:

Upper Limit = 250.0

Lower Limit = 0.0

Range.Upper Limit Voltage Value

Range.Lower Limit Voltage Value

These parameters are only used for gauges with analog voltage interface.

The values corresponds to Range.Upper Limit Data Value and Range Lower Limit Data Value

Example:

Upper Limit: 10.0V        à  250mTorr Range Upper Limit Data Value

Lower Limit: 0.0V        à  0.0mTorr Range Lower Limit Data Value

Filter.Enable

True enables the filter

Filter.Type

Available since April 2021. Low-pass Simple is backwards compatible.

Filter.Time

Set filter time in the range of 0.0 to 1.0 second.

Note: Filter delays the sensor signals which is detrimental for        pressure control
