Frequently Asked Questions - SFAB-600U-HQ10-PNLK-PNVBA-M12 Festo

How do I reset the Festo SFAB-600U flow sensor to factory settings?

Switch off the operating voltage, then press and hold the [A], [B], and [Edit] buttons simultaneously while switching the power back on. The sensor will be in RUN mode with factory defaults restored. All custom settings will be lost.

What gases can be measured with the SFAB-600U?

The sensor can measure compressed air (ISO 8573-1:2010 [6:4:4] or [7:4:4]), nitrogen, argon, and carbon dioxide. Select the gas type in the 'Spec' menu under 'GAS'.

How to teach switching points manually?

In RUN mode, generate the first flow rate for TP1, then press [A] and [Edit] simultaneously (for OutA) or [B] and [Edit] (for OutB). 't-IN' flashes. Then generate the second flow rate for TP2 and press [A] and [Edit] again. The switching points are set. Ensure the switching function is configured in EDIT mode first.

Can the display be rotated?

Yes, the display can be rotated in 90° steps up to approx. 270°. To rotate, gently turn the display unit by hand until it clicks into the desired orientation.

What does the 'LOCK' symbol mean on the display?

The 'LOCK' symbol indicates that a security code is active. To edit parameters, you must enter the 4-digit code. If forgotten, restore factory settings (see FAQ 1) which will clear the code.

How to clean the SFAB-600U sensor?

Disconnect power and compressed air. Clean the outside only with a soft cloth and mild cleaning agents that are compatible with PA and inspection window material. Do not use abrasive cleaners.

What is the maximum cable length for IO-Link operation?

For IO-Link communication, the maximum cable length is 20 meters. For standard switching/analogue operation, up to 30 meters is allowed.

How to perform zero point synchronization?

Ensure no flow is present and operating pressure is applied. Set 'Z.Adj' to 'ON' in the SPECIAL menu. In RUN mode, press [A] and [B] simultaneously, then press [Edit]. 'OK' indicates success. If 'FAIL', check flow is zero and pressure is stable.

What types of mounting are available for the sensor?

4.2 Function

4.2.1 Functional principle

The sensor measures the standard flow rate or mass flow rate with the help of a thermal procedure. The sensor measures the amount of heat that is drawn from the heated surface of a micro-mechanical sensor element by the medium flowing past. The sensor determines the flow rate or the accumulated volume from the amount of heat removed and shows this on the display. The sensor calculates the temperature of the medium from the sensor signals. The sensor is connected to higher-level

Product overview

systems via switching outputs, a volume switching pulse, an analogue output or an IO-Link interface. Depending on the configuration, the switching outputs monitor a threshold value or a signal range. The outputs can be set as PNP or NPN and normally open (NO) or normally closed (NC). The analogue output can be operated either as a voltage output or as a current output. Through the IO-Link interface, process values can be read out and parameters changed and transmitted to additional devices. If the flow rate is integrated, a volume signal or mass signal can be calculated and output via a pulse output and an accumulated measured value via IO-Link.

Tab. 6: 2-point threshold value comparator

4.2.3.2 Colour change

A red colour change can be set in the display for the switching outputs OutA and OutB dependent on the switching status. The colour change enables the system status to be identified from a distance. The red display is always dominant.

Parameter Meaning
‘bLUE’ The display is always blue; the colour change function is switched off.
‘R.On’ The display is red when the switching output is set (high = 1).The display is blue when the switching output is not set (low = 0).
‘R.OFF’ The display is red when the switching output is not set (low = 0).The display is blue when the switching output is set (high = 1).

Tab. 7: Change in colour of display

4.2.3.3 Volume measurement and mass measurement

A threshold value for the volume or the mass is set in the accumulated volume measurement or mass measurement. If the configured threshold value is reached, the SFAB outputs a switching pulse at the switching output OutC. The volume measurement or mass measurement is restarted at every switching pulse. The pulse width is adjustable.

Tab. 8: Volume pulse with accumulated volume measurement

4.2.4 Filter

The filter smoothes the flow rate measurement signal in 12 stages. Smoothing affects all outputs. The switching times of the flow-related switching outputs and the rise time and fall time of the analogue output change. The filter time equals the time constant T of a low-pass filter.

    B --> H["volume / mass measurement"]

Fig. 4: Effect of filter settings

The display filter only affects the flow rate measured value in SHOW mode [AVER].

4.2.5 Analogue output

Analogue signal

The signal of the analogue output can be assigned the physical measured variables of flow rate or temperature. The physical measured value of flow rate is configured as standard.

Output signal

The analogue output can be configured either as voltage output 0 ... 10 V oder 1 ... 5 V or as current output 4 ... 20 mA. By default the voltage output is set to 0 ... 10 V.

Scaling of the analogue signal

The default setting for the analogue output signal is 0 ... 10 V, 1 ... 5 V or 4 ... 20 mA for the complete sensing range "Full Scale (FS)". If only part of the sensing range is to be used, the analogue value output can be scaled to the partial range.

The analogue output can also be scaled in the negative range up to -100%FS.

Fig. 5: Example: scaling of the analogue signal at the current output

4.2.6 Security code

A 4-digit numeric code can be set to protect the device settings from unauthorised access. The security code must be entered in EDIT mode and TEACH mode when changing settings. The IO-Link interface offers additional options for blocking access → 8 IO-Link interface description.

4.2.7 Minimum value and maximum value

The minimum values and the maximum values for the flow measurement or the temperature measurement are displayed and reset in the SHOW mode.

i

The minimum and maximum values are reset when the operating voltage is switched off.

4.2.8 Replication of the parameters

This function enables all settings that have been carried out on one sensor (master) to be transferred to other identical sensors (device).

Parameters are transferred with the IO-Link functions. The previously configured master sensor is set to a master mode, which enables it to transfer its parameters to an identical device sensor.

4.2.9 Switchover of standard condition

The represented flow rate units and volume units can be related to different standard conditions. It is possible to switch between the following standard conditions. In the menu navigation on the display, the corresponding standard is determined by selecting the reference temperature.

REF / Cond Off 15 °C 20 °C
Standard DIN 1343 ISO 2533 ISO 6358 /			ISO 8778
Air pressure (absolute) [kPa] 101.325 101.325 100
Temperature [°C] 0 15 20
Humidity [%]	0 0 65
Status information "Option"	Does not light up	Lights up	Lights up
Correction factor, measurement range end value	1 1.055	1.087

Tab. 9: Standard conditions for flow rate units and volume units

Calibration of the sensor refers back to the physical standard conditions in accordance with DIN 1343. If a standard other than DIN 1343 is selected, the specified measurement range ( ± 100 % FS) changes in value by the factor specified in ➤ Tab. 9 Standard conditions for flow rate units and volume units. This change is visualised in the display through ‘Option’.

Changing the reference standard only adjusts the display on the sensor. If necessary, the effect on the nominal measurement range of the respective sensor must also be considered when evaluating the analogue output.

4.2.10 Zero point synchronisation

If the sensor is installed vertically, the measurement may deviate at high pressures. An offset synchronisation can be carried out to compensate for the measurement deviation. This offset synchronisation affects the display and all outputs. The offset synchronisation is possible only for the Zero Adjust = ON setting and the zero range hiding is no longer active. The offset error is visible on the display and can be set to zero using a zero-adjust teach process.

8.7 IO-Link teach-in

The sensor supports two different IO-Link teach functions for all IO-Link switching channels (SSC):

– Single value teach-in according to IO-Link specification
- Device-specific teach-in

Carry out the following steps before teaching:

1. Configure the switching channel according to the application including switching mode, switching logic and hysteresis.

The switching mode must not be deactivated (OFF).

1. Set the teach channel to the desired switching channel (parameter 0x003A).

Single value teach-in according to IO-Link specification

With the single value teach-in, SP1 and SP2 are taught in with separate commands. After each command, the parameter set of the switching channel is checked for validity. If the parameter set is valid, the teach point is immediately accepted as the switching point. If the parameter set is invalid, the process is aborted.

1. Set the desired flow rate.
2. Perform the teach process: 0x41 for SP1 and 0x42 for SP2.
3. To set the second switching point, repeat steps 1 and 2.
   For more information, see IO-Link Smart Sensor Profile.

Device-specific teach-in

The device-specific teach-in (0x4B) behaves in the same way as the manual teach-in on the device. Instead of pressing a button manually, the two teaching points are set with the IO-Link command. The chronological order is irrelevant. In the window mode and in the two-point mode, the 2 teaching points are assigned to the switching points SP1 and SP2 in such a way that the parameter set is valid. The

teach values are only accepted after the second teach-in. With the teach-in of the single point mode, the switching point results from the mean value of the two teaching points: SP = 1/2 (TP1 + TP2). The keys [A], [B] and [Edit] are locked during the teach-in. The display flashes alternately 't-IN' and 'IOL'.

1. Set the first desired flow rate.
2. Send the teach-in command 0x4B.

3. Set the second desired flow rate.

4. Send the teach-in command 0x4B.

The teach process is aborted with the command 0x4C.

Recommendation: After teaching, read out the parameter set and check whether the settings match the application.

8.8 Block parameterisation

Block parameterisation is used to prevent individual parameter values from being incompatible with the values stored in the device. All parameters transmitted as a block will be simultaneously accepted and activated.

9 Operation

i

Changes to the device settings take effect immediately at the outputs.

i

Ready-state delay

Note the ready-state delay. After this time, the electrical outputs take a defined, stable condition.

The flow rate displayed refers to the standard condition that was set in the Spec menu under 'REF' / 'Cond'.

When comparing volumetric flow rates, note the following:

• Make sure that the volumetric flow rates to be compared refer to the same standard conditions, e.g. operating volumetric flow rate, amount supplied by a compressor, measured values of a sensor from another manufacturer.
• After the supply voltage is switched on, note the warm-up time before it reaches the specified accuracy 13 Technical data.

9.1 Reset sensor to factory setting

i

By resetting to the factory settings, the current settings are lost. Note down current settings before resetting.

1. Switch off the operating voltage.
2. Press and hold the [A] button, the [B] button, and the [Edit] button.
3. Switch on the operating voltage.
   The sensor is in RUN mode.

10 Cleaning

1. Turn off energy source and compressed air.
2. Clean the outside of the sensor with media that are gentle on the material.

Tab. 29: Technical data

13.1 Examples for calculating the maximum error of the display

• Flow rate measuring range: 10 ... 1000 l/min (FS = 1000)
• Measured value: 600 l/min

Spread error (e.g. ± 3 % FS) Zero point error

Tab. 30: Spread error and zero point error

Spread error and zero point error

The spread error is proportional to the measured value. At 600 l/min, the spread error is 3% of the measured value = 18 l/min.

The zero point error is independent of the measured value. It is 0.3% FS = 3 l/min.

Display error under nominal conditions (6 bar, 23 °C):

The display error under nominal conditions is the result of adding the spread and zero point errors. The actual flow rate is in the range of 600 ± (18+3) l/min = 600 ± 21 l/min.

Display error under deviating nominal conditions (e.g. 8 bar, 40 °C):

Temperature and pressure errors are spread errors. The temperature error at 40 °C is ±0.1% FS/K x 17 K = ±1.7% of the measured value = ±10.2 l/min.

The pressure error at 8 bar is ± 0.5% FS/bar x 2 bar = ± 1% of the measured value = ± 6 l/min.

The error of the display at deviating nominal conditions results from the addition of all error values (span, zero point, temperature, pressure). The actual flow rate is therefore in the range of 600 ± (18 + 3 + 10.2 + 6) l/min = 600 ± 37.2 l/min.
