ANALOG OUTPUT
7.5 TUNE MIN (4MA)
Use this setting to precisely tune the minimum analog output value (initial
value is 4 mA). This value can differ slightly due to ambient influences such
as temperature.
Before tuning the signal, make sure the analog signal is not being
used for any application.
After pressing PROG, the current will be about 4 mA. The current can be
increased / decreased with the arrow-keys and is directly active. Press
PROG to store the new value.
7.6 TUNE MAX (20MA)
Use this setting to precisely tune the maximum analog output value (initial
value is 20 mA). This value can differ slightly due to ambient influences
such as temperature.
Before tuning the signal, make sure the analog signal is not being
used for any application.
After pressing PROG, the current will be about 20 mA. The current can be
increased / decreased with the arrow-keys and is directly active. Press
PROG to store the new value.
7.7 FILTER
Stabilizes the analog output signal. The output value is updated 8 times a
second. This digital filter setting produces a more stable but less actual
reading. The filter principal is based on three input values: the filter level
(01-99), the last analog output value, and the last average value.
The higher the filter level, the longer the response time of a changed value.

MENU 8: PULSE OUTPUT
The “Pulse” menu configures the behavior of the digital output signals. As standard, one transistor
output is available (Type OT): D1. Its function is based on the mode selected at
8.1: PULSE OUTPUT >
MODE
.
Optionally, one relay output is available (Type OR): D5. Its output functionality corresponds to the
functionality of output D1.
The digital (transistor) output D1 has a maximum frequency of 500 Hz (scaled pulse output).
Make sure the output frequency of the optional digital (relay) output D5 does not exceed 0.5 Hz,
otherwise the relay lifetime and reliability will be reduced significantly.
