GENERAL DESCRIPTION OF FLOW SENSOR
The FlowSensor Object describes only general information. A flow sensor supports up to 10 different gas calibrations.
Every gas calibration can be identified by the last characters (e.g. _1 .. _10). The number represents data for the
corresponding gas calibration.
Every gas calibration consists of following objects:
- Sensor _x
Common calibration information
- Cal_AD _x
Calibration points of sensors raw values
- Cal_Q _x
Calibration points of flow values in Nl/min
- Cal_AD_Customer _x
Customer calibration points of sensors raw values is used, if userdefined curve is activated in Sensor _x Object
- Cal_Q_Customer _x
Customer calibration points of flow values in Nl/min is used, if userdefined curve is activated in Sensor _x Object
- Sensor specific part (e.g. SFS7011 _x)
includes specific data for the corresponding sensor type which is choosen in FLowSensor Object
SETPOINT SOURCE
Possible setpoint sources.
It’s used if calibration is inactive.
0. EnSetpointSource_BUS
use Setpoint_Nl_min.w (2540sub1)
or alternative Setpoint_w (3800sub1)
1. EnSetpointSource_Manual
It’s used in bueS mode for manual setpoint manipulation by e.g. display
2. EnSetpointSource_FixValue
Controller.Stored_Setpoint_InPerCent (3811sub4)
3. EnSetpointSource_OpenLoop
Controller is in open loop mode and don’t manipulate the
valves duty cycle.
Valves duty cycle is manipulated directly by Dutycycle Object (0x2542sub1), if it’s not specified by
ActuatorOveride for other behaviour.
4. EnSetpointSource_Analyze
An device internal profile is processed. It includes several setpoints and durating times to analyse step responses
in different ranges. After profile finished last setpoint source is used again.
At minimum timestamp, Current Setpoint Nl_min (0x2500), Actual Flow Nl_min (0x2501) and Current Dutycycle
(0x2502) have to be logged by e.g. Buerkert Communicator to analyse the systems behaviour.
SFS7011 OPERATION MODE
Possible operation modi:
0. EnOperationMode_SFS7011_ BandGap
1. EnOperationMode_SFS7011_ TP3
SFS7011 MULTIPLEXER
Possible multiplexer settings:
0. EnFactorySetting_SFS7011_multiplexer_flow_signal (TP1 - TP2)
1. EnFactorySetting_SFS7011_multiplexer_sum_thermopiles (TP1 + TP2)
2. EnFactorySetting_SFS7011_multiplexer_single_thermopile_tp1
3. EnFactorySetting_SFS7011_multiplexer_single_thermopile_tp2
4. EnFactorySetting_SFS7011_multiplexer_additional_thermopiles_tp3 (spy – thermopiles)
SFS7011 HEATER
Possible heater settings:
