CONFIGURABLE FUNCTIONS
4.13 Digital outputs
The Bulkscan has six digital outputs on which the sensor can signal that certain totals
have been reached, limits have been exceeded or dropped below, or the occurrence of
information/warnings.
Theoutputscanbeusedasdigitaloutputstogroundorasoatingoutputs(see"6.3
Wiring the inputs and outputs to the external components“ on page 42).

Information ( Yellow):
The sensor continues to
measure.
The output remains active until the prob-
lemisrectied.
Warnings ( Orange):
The sensor no longer
measures
Volume quota
Mass quota
Reaching the volume
quota or mass quota
The output behaves like a pulse output.

• Dropping below the
lower limit
• Exceeding the upper
limit
The output behaves like a switching
output.

Tab. 4: Behavior as output Information/Warnings
It is possible to set a switching delay time. for the digital output.
Warnings that are present for a short time only are not issued via the digital output if
the switching delay times are long.
Behavior as pulse output
If the set Volume quota or Mass quota is reached, a pulse is transmitted from the digi-
tal output. You can set the Pulse width to between 20 ms and 10 s.
