10.3 Output configuration
This chapter describes the options for the output signals at OUT1 and OUT2.
10.3.1 Switching signal for limit value monitoring
A switching signal can be output for process value monitoring. OUTx changes its switching state when
the set switching limits are exceeded or not reached. You can choose between hysteresis and window
function.

t: Time
SP: Set point
rP: Reset point
HY: Hysteresis
Hno: Hysteresis function NO (normally open)
Hnc: Hysteresis function NC (normally closed)
When the hysteresis function is set, the set point [SP] and the reset point [rP] are set. The rP
value must be lower than the SP value. The difference between SP and rP is at least 0.5 % of
the final value of the measuring range (= hysteresis). If only the set point is changed, the reset
point is changed automatically; the difference remains constant.

When set to the window function, the window high [FH] and the window low [FL] are set. The
difference between FH and FL is at least 0.5% of the final value of the measuring range. FH and
FL have a fixed hysteresis of 0.25% of the final value of the measuring range. This helps keep
the switching status of the output stable if the flow rate varies slightly.

10.3.2 Switching signal Diagnosis
The unit features an integrated diagnostic function. When using the diagnostic function, the output is
used exclusively for diagnostic message output, which it indicates by a switched signal.
Ultrasonic flow meter SUH200 SUH201 SUH400 SUH401
27
The switching output is switched on in normal operation (normally closed) and the switching status
LED lights yellow.
If the unit detects a diagnostic case, the output is switched off and the switching status LED goes out.
Diagnostic cases are:
• reversal of the flow direction ( Switching signal for flow direction 27)Ò/
• low signal quality/ no signal ( Switching signal for signal quality 27)Ò/
10.3.2.1 Switching signal for flow direction
A flow direction change can be monitored by providing a switching signal.
An arrow with the text “flow direction” on the device indicates the positive flow direction. The direction
of the flow measurement can be reversed using the parameter [Fdir].
See Flow direction.
The output is switched on until the volumetric flow falls below the set minimum volumetric flow quantity
in negative flow direction (-LFC)(1).
Then the following applies:
• The output switches ON when volumetric flow is above +LFC (2).
• The output switches OFF when volumetric flow is below -LFC (3).

SUH200 SUH201 SUH400 SUH401 Ultrasonic flow meter
28
The signal quality of the sensor can be affected by irregularities in the medium (e.g. strong
turbulences, air bubbles, particles or build-up).
The unit detects the signal quality in three stages:
Signal quality Explanation Operating status
LED Switching output
Normal The unit operates without restrictions (normal operation). Lights green On
Low The signal quality is disturbed, but the unit is still work-
ing within its specifications.
Lights blue OFF
No signal No medium is present or no signal can be created. Flashes red OFF

uCall up [Parameters] > [Output Configuration].
uSelect [oux] and set [dOU].
uSelect [dFUx] and set [Signal quality detection]
10.3.3 Consumed quantity monitoring (totaliser function)
The unit has 3 internal quantity meters (totalisers Vol.1, Vol.2 and Vol.L). The totalisers continuously
sum up the consumed quantity and provide this process value both on the display and via the IO-Link
interface.
Totaliser Process value Read access via IO-Link
Vol.1 Consumed quantity 1
(This value is used for consumed quantity monitoring by
switching or pulse signals)
Cyclic
Vol.2 Consumed quantity 2 Acyclic
Vol.L Consumed quantity over the whole lifetime (lifetime totalis-
er)
Acyclic
The totalisers Vol.1 and Vol.2 take account of the flow direction when totalising the consumed
quantity: .Counting method of the totalisers ( 40)Ò/
OUT1 and OUT2 cannot be used simultaneously for the consumed quantity monitoring.
In addition to the current consumed quantity, the value before the last reset is saved. This value and
the time since the last reset can also be displayed.
The totaliser saves the totalled volumetric flow quantity at regular intervals. After a power failure
this value is available as the current meter reading. If a time-controlled reset is set, the elapsed
time of the set reset interval is also saved. This means that the possible data loss can amount
to one minute.
See also: .Read totaliser values ( 46)Ò/
The accuracy of the consumed quantity measurement depends on the accuracy of the volumetric flow
measurement.
A switching signal or pulse signals can be provided for consumed quantity monitoring.

• See Pulse signal totaliser ( 30)Ò/
Ultrasonic flow meter SUH200 SUH201 SUH400 SUH401

10.3.3.1 Switching signal totaliser
A switching signal can be provided for consumed quantity monitoring.
When the Vol.1 totaliser has totalled the volumetric flow quantity set under [ImPS], the output provides
a switching signal. The output remains switched until a totaliser reset is carried out.
The totaliser reset for the totalisers Vol.1 and Vol.2 can be set via the parameter [rTo1] or [rTo2].
When the totaliser has been reset, metering starts again.
• [rTox] = OFF:
automatic reset of totaliser switched off.
A reset is done manually or in case of overflow.
• [rTox] = …h/d/w (hours/days/weeks):
automatic reset of the totaliser after the set time.
– If totaliser Vol.1 reaches the volumetric flow quantity [ImPS] before the set time, no automatic
reset occurs. The output remains switched until totaliser Vol.1 is reset manually or via overflow.
– Totaliser Vol.2 is independent of the settings of [ImPS]. Its count is not taken into account for
the switching and pulse signals.
The totalisers can be reset manually at any time via the [rTox] parameter. Totaliser Vol.1 can
additionally be reset via an external signal at pin 2.

10.3.3.2 Pulse signal totaliser
Pulse signals can be provided for consumed quantity monitoring.
Every time the volumetric flow quantity (pulse value) set under [ImPS] has been reached, the output
provides a pulse signal.
The pulse signal consists of a short switching on and off of the output. The switching status LEDs on
the unit do not display the switching operation.
Pulse signals are not available via the IO-Link interface.

10.3.4 Analogue signal
The unit provides an analogue signal of 4…20mA proportional to the process value.
The measuring range is scalable:
• [ASP] determines at which measured value the output signal is 4 mA.
• [AEP] determines at which measured value the output signal is 20 mA.
Minimum distance between ASP and AEP = 20 % of the final value of the measuring range.
If the measured value is outside the measuring range or in the event of an internal error, the current
signal indicated in the following figure is provided.
For measured values outside the display range or in case of an error, messages are displayed (cr.UL,
