Monitoring of the lower temperature limit
The current temperature in the positioner housing is measured by a
sensor on the electronic circuit board. This parameter is for the
three-level monitoring of the lower temperature limit.
Temperature unit
The temperature unit can be switched over by pressing the Greater
Than or Smaller Than button between °C and °F. Another way of
switching over is the J1.TUNIT parameter for monitoring the upper
temperature limit. The selected unit applies to all temperature-related
parameters.
Threshold 1
First threshold for monitoring the lower temperature limit. The factory
setting is --25.0 °C. If the temperature falls below the set value, the
threshold 1 error message is triggered.
Threshold 2
Second threshold for monitoring the lower temperature limit. The
factory setting is --30.0°C. If the temperature falls below the set value,
the threshold 2 error message is triggered.
Threshold 3
Third threshold for monitoring the lower temperature limit. The factory
setting is --40.0°C. If the temperature falls below the set value,
the threshold 3 error message is triggered.
