6.6.14.7 Temperature for Current Output Value 100 %
In this menu the temperature value is entered for which the current output is to indicate its 100 % value (20
mA). The menu is only displayed when the current output is based on the temperature.
Minimum: -50 °C
Maximum: 180 °C
The temperature value for a current output value of 100 % must be at least 10 °C larger than the temperature
value for a current output value of 0 %.
6.6.14.8 Alarm Current High/Low
In this menu a selection can be made if the current output during an alarm condition is to be set to High-
Alarm-Current or the Low-Alarm-Current. For some error conditions the current output, independent of the
selection, is always set to the High-Alarm-Current or to the Low-Alarm-Current (see Alarm Overview).
6.6.14.9 Value of the Alarm Current at Low Alarm
In this menu the value of the Low-Alarm-Current can be entered. The setting for the alarm current is a func-
tion of the current output range selected. For the current output range 0
−
20 mA the alarm current is 0 mA.
For the current output range 4
−
20 mA the Low-Alarm-Current can be set between the limits of 2
−
3.6 mA.
When the current output range is changed, the Low-Alarm-Current is automatically adjusted by the convert-
er for the new current output range (current output range 0
−
20 mA to 0 mA and 4
−
20 mA to 2 mA).
6.6.14.10 Value of the Alarm Current at High Alarm
In this menu the value of the High-Alarm-Current can be entered. The setting for the alarm current is inde-
pendent of the current output range selected since all range end values are 20 mA. The High-Alarm-Current
can be set between the limits of 21 mA and 26 mA.
