11.2.4.24 Diagnostic value '28.SSUP - Slow step zone up' / '29.SSDN - Slow step zone down'
Display range: 0.1 ... 100.0
Purpose: The slow step zone is the zone of the closed-loop controller in which
control signals are issued in a pulsed manner. Display is in percent.
The impulse length is thus proportional to the control deviation. If
the control deviation is beyond the slow step zone, the valves are
controlled using permanent contact.
This parameter can be set for special applications.
Factory setting: 10.0

11.2.4.25 Diagnostic value '30.TEMP - Current temperature'
Display range: °C: -50 ... 100
°F: -58 ... 212
Purpose: Current temperature in the positioner enclosure. The sensor is
present on the basic electronics. In order to switch over the temper‐
ature display between °C and °F, press the button.
11.2.4.26 Diagnostic value '31.TMIN - Minimum temperature' / '32.TMAX - Maximum temperature'
Display range: °C: -50 ... 100
°F: -58 ... 212
Purpose: The minimum and maximum temperatures within the enclosure are
constantly determined and saved as with a min/max pointer. This
value can only be reset in the factory.
In order to switch over the temperature display between °C and °F,
press the button.
