Description
Selection of the operating mode for the digital output 51 / 52.
• Off: Digital output deactivated.
• Logic: Digital output functions as binary output (for function see parameter '„...Setup Logic Output').
• Follow DO 41 / 42: The digital output 51 / 52 follows the function of digital output 41 / 42. Depending on the setting of
the parameter 'Input / Output / ...Dig.Out 51 / 52 / Outp. Flow Direction', digital output 51 / 52 is operated in pulse
mode as follows:
- No pulses are issued if 'Forward & Reverse' is selected. Only digital output 41 / 42 is active.
- If 'Forward' is selected, pulses for forward flow are issued on digital output 41 / 42, while pulses for reverse flow are
issued on digital output 51 / 52.
- If 'Reverse' is selected, pulses for reverse flow are issued on digital output 41 / 42, while pulses for forward flow are
issued on digital output 51 / 52.
• 90° Shift: Output of the same pulses as for digital output 41 / 42, phase shifted by 90°.
• 180° Shift: Output of the same pulses as for digital output 41 / 42, phase shifted by 180°
Selection of the operating mode for digital output V1 / V2.
Digital output V1 / V2 is only available if the corresponding plug-in card is present!
• Off: Digital output V1 / V2 deactivated.
• Logic: Digital output V1 / V2 as a binary output (for example, as an alarm output).
Selection of the operating mode for digital output V3 / V4.
Digital output V3 / V4 is only available if the corresponding plug-in card is present!
• Off: Digital output V3 / V4 deactivated.
• Logic: Digital output V3 / V4 as a binary output (for example, as an alarm output).
Selection of process value issued via the frequency or pulse output.
Only if digital output 41 / 42 has been configured as a frequency or pulse output.
Available process variables on page 80
Selection of the output function for the relevant binary output.
• F / R Signal: The binary output signals the flow direction.
• Dual Range: The binary output is activated when measuring range 2 (QmMax 2 / QvMax 2) is selected. This selection is
only available if the parameter 'Range Mode Config' has been configured to Qm or Qv.
• Batch End Contact: The binary output is activated when the set fill quantity is reached (only if the FillMass function is
activated).
Only if the relevant digital output has been configured as a binary output.
Set pulses per volume or per mass flow unit, and the pulse width for the digital output operating mode 'Pulse'.
Only available if a digital output has been configured as a pulse output, and the volume flow or mass flow has been selected
as the process variable to be output.
Sets the upper range value frequency for the digital output operating mode 'Frequency'. The entered value corresponds to
100 % flow.
Only available if a digital output has been configured as a frequency output, and the volume flow or mass flow has been
selected as the process variable to be output.
Starts the automatic zero point balancing using
Note
Prior to starting the zero point adjustment, make sure that:
• There is no flow through the sensor (close all valves, shut-off devices etc.)
• The sensor must be filled completely with measuring medium for measurement.
. Automatic zero point balancing takes approx. 60 seconds.
