7.3.3.5
Alarm
The alarm output can be configured via the switching function for Q1 and Q2.
For a detailed functional description,
see "Non-safety-related functions", page 20

Function
Description
Alarm
In
Alarm
switching mode, the switching threshold is automatically
defined based on the measuring capability of the device. In this case,
the switching output behavior can be manually selected.
Switching behavior
With the
Q1 output behavior
setting, you can manually select whether
the signal level warning output is
Active high
or
Active low
.
Example alarm parameterization for Q1:
1.
Connect to the device and switch to the
Outputs settings
page in SOPAS ET.
2.
Set the Q1 switching function to
Alarm
.
3.
Set the Q1 output behavior according to the desired function:
Active low
4.
Transfer parameters the device using the “Write all parameters” button.
5.
Check whether the function works appropriately for the configured parameters!
7.3.3.6
Analog output
If the 4 mA … 20 mA setting is selected, output 2 functions as an analog current
output. The measured value of the device is output as a proportional-linear current
value that corresponds to the other device settings. Increasing (safety-related) and
decreasing (non-safety-related) scaling is possible.
The necessary settings can either be taught-in or set manually. These are described in
the following.
For a detailed functional description,
see "Safety-related functions", page 16
and
safety-related functions", page 20
NOTE
The analog output has a resolution of 12 bits.
Depending on whether the larger distance value is taught in for 4 mA or for 20 mA, the
analog output behavior is either “increasing” (distance for 4 mA < distance for 20 mA)
or “decreasing” (distance for 4 mA > distance for 20 mA).
