10.4.3.8 Description of parameter H
H.
TMIN - monitoring the lower limit temperature
Use this parameter to activate the test to continuously monitor the lower limit temperature
inside the enclosure. The current temperature in the enclosure is recorded by a sensor on
the electronic printed circuit board. The limit temperature is monitored in three stages.
Configure the following settings to activate the test:
1. Set the "H.
TMIN" parameter to "On". Sub-parameters to set the test parameters are
displayed. The test is activated.
2. Set the suitable parameter values in sub-parameters. The setting options available in
sub-parameters are described below.
The positioner triggers a fault message if the lower limit temperature undershoots a
threshold during the test.
The factory setting is "OFF".
H1.TUNIT - temperature unit
Use this sub-parameter to set the temperature unit "°C" or "°F". The selected temperature
unit is then also applicable for all other temperature-based parameters.
The factory setting is "°C".
H2.LEVL1 - threshold 1
Use this sub-parameter to set a threshold in "°C" or "°F". Use threshold 1 to monitor the
lower limit temperature. Set the threshold in a range from "-40.0C" to "90.0C" or "-40.0F" to
"194.0F".
The positioner triggers a fault message if the current temperature inside the enclosure
undershoots threshold 1. The process to activate and display this fault message is described
in the "XDIAG" parameter.
The factory setting is "-25.0C".
H3.LEVL2 - threshold 2
Use this sub-parameter to set a threshold in "°C" or "°F". Use threshold 2 to monitor the
lower limit temperature. Set the threshold in a range from "-40.0C" to "90.0C" or "-40.0F" to
"194.0F".
The positioner triggers a fault message if the current temperature inside the enclosure
undershoots threshold 2. The process to activate and display this fault message is described
in the "XDIAG" parameter.
The factory setting is "-30.0C".
