… / ...Dig.Out 41/42 / ...Binary Out 41/42
The following parameters are only available if the digital output 41 / 42 has been configured as a binary output.
4024
Signal Source Binary
TUSIGN8 [1]
2: Alarm signal
4: End contact fill function
Selection of binary output function.
• Alarm signal: the binary output functions as an alarm output. The alarm type is
selected with the parameters „...Alarm Cfg. 41/42“.
• End contact fill function: the binary output is activated when the set fill
quantity is reached (only if the FillMass function is activated).

4029 General
Alarm
TUSIGN8 [1]
0: Off
1: On
Selection of error messages signaled via the binary output 41 / 42.
Only if the parameter „Signal Source Binary“ has been set to 2 - Alarm signal.

output
2: Frequency output
5: 90° phase rotation
6: 180° phase rotation
Selection of the operating mode for the digital output 51 / 52.
The operating modes ‘Follow DO1’, ‘90°’ and ‘180°’ are only available if digital
output 41 / 42 has been configured as a pulse output.
• Off: Digital output deactivated.
• Binary: Digital output functions as binary output (for function, see the
parameter ‘Signal Source Binary’).
• Frequency: Digital output functions as frequency output (for process value see
the parameter ‘Signal Source Freq..’). In frequency mode, a frequency
proportional to the flow rate is given as output.
• 90° phase rotation: 90° phase rotation of output of the same pulses as for
digital output 41 / 42.
• 180° phase rotation: 180° phase rotation of output of the same pulses as for
digital output 41 / 42.
