Support
The FST020 transmitter can be connected to sensor types FSS200 and FSS300.
This manual contains a description of all device parameters and is aimed at persons
configuring the device.
The default settings and the setting ranges are listed in tables for each parameter.
Furthermore, the relation, if any, between parameters is described.
As of chapter 3, Setup (Page 19), the chapter and subchapter numbers equal the parameter
numbers in the HMI structure.
For parameters with access level other than User (for example Read only or Expert), the
access level is stated in parenthesis after the parameter name.
The device offers a set of wizards which will guide you through configuration of parameters
essential for your application. The quick commissioning wizards are described in the
Commissioning chapter of the device Operating Instructions.
For product support, or to contact a Siemens representative, see Technical support
(Page 187).

The quick start wizard topics and introductory explanations are listed below. For detailed
quick start wizard procedures refer to the FST020 Operating Instructions manual.
Quick commissioning - The Quick commissioning wizard will guide you through configuration
of parameters essential for your application. You configure parameters essential for your
application by selecting the configuration path and sub-wizards appropriate for your
application.
The sensor settings wizard will guide you through configuration of essential parameters.
The Process values wizard will guide you through setup of process values for your
application. The prioritizing of the process values automatically configures the measurement
views on the display. The process value configured as 1st process value appears as first
value in the views.
The Inputs and outputs wizard will guide you through setup of inputs and outputs on the
available channels.
This wizard allows you to copy the configuration from the SensorFlash to the device.

selected flow rate.

– Operation mode = Pulse output
– Process value = Mass flow
– Amount per pulse = 1 kg
– Pulse width = 1 ms
● Measured mass flow value = 10 kg/s (constant)
Result:
● Pulse repetition = 100 ms
● Output frequency = 10 pulses per second with a pulse width of 1 ms
● Remaining time between pulses is 99 ms
remaining time is always greater than pulse
The frequency output function supplies a frequency (50% duty cycle) proportional to the
selected process value.
Frequency is calculated as follows:
This example shows how to calculate the output frequency for any measured flowrate:
Frequency output configuration:
● Operation mode = Frequency output (Channel 2 to 4)
● Process value = Mass flow
● Direction = Positive
● Frequency value high = 12 kHz
● Frequency value low = 2 kHz
● Upper range value = 15 kg/s

3.4 Inputs and outputs
Sets the Damping (filtering) to smooth out response to sudden changes in measurement.
An increase to Damping value increases response time of device, and affects digital value
and loop current. If output values are noisy, increase Damping value. For faster response
time, decrease Damping value. Find a value that meets requirements of signal stability and
response time.
Setting 0.00 s to 100.00 s
Current output reaction in case of a fault.
Path Setup → Inputs and outputs → Channel 2 - output → Current output → Fail-safe behaviour
Output value in case of a fault and when fail-safe behaviour configured to fail-safe value.
