23 IMPDN - pulse length DOWN

Communication object: [PULS_LENGTH_DO]
The smallest impulse lengths that can be used to move the actuator are determined during the initialization process. They
are separately determined for the "Up" and "Down" directions and displayed here.
This parameter can be set for special applications.

24 DBUP - deadband UP

Communication object: [DEADBAND]

25 DBDN - deadband DOWN

Communication object: [DEADBAND]
The deadbands of the closed-loop controller in the "Up" and "Down" directions are displayed here. The values correspond
either to the manually configured value of the "DEBA" parameter or to the value automatically adapted by the device if
"DEBA" was set to "Auto".

26 SSUP - short step zone UP

Communication object: [SERVO_GAIN_UP]
This parameter can be set for special applications.
27 SSDN - short step zone DOWN
Communication object: [SERVO_GAIN_DOWN]
The short step zone is the zone of the closed-loop controller in which control signals are issued in a pulsed manner. The
impulse length is thus proportional to the control deviation. If the control deviation is outside the short step zone, the valves
are controlled using permanent contact.
This parameter can be set for special applications.
28 TEMP - current temperature
Communication object: [TEMPERATURE]
Current temperature in the positioner enclosure. The sensor is provided on the electronic printed circuit board.
The temperature display can be toggled between °C and °F by pressing the decrement button.
29 TMIN - minimum temperature ("min/max pointer")
Communication object: [MIN_TEMPERATURE]
30 TMAX - maximum temperature ("min/max pointer")
Communication object: [MAX_TEMPERATURE]
The minimum and maximum temperatures inside the enclosure are continuously determined and saved using a min/max
pointer. They can be reset only in the factory.
