Impulse length up
and
Impulse length down
During initialization the smallest impulse lengths are determined with
which a movement of the actuator can be achieved. They are
determined and displayed here for the "Up"--direction and the
"Down"--direction.
These two parameter can be tuned for special applications (see
chapter 4.7 page 126).
Dead zone up
and
Dead zone down
Here the dead zone of the controller is displayed in "Up"--direction or in
"Down"--direction. The values correspond either to the manually set
value of the parameter "34.DEBA" or the value adapted automatically
by the instrument when "DEBA" has been set to "Auto".
Short step zone up
and
Short step zone down
The short step zone is the range of the controller in which
pulse--shaped control signals are output. The impulse length here is
proportional to the control error. If the control error is outside the short
step zone, the valves are controlled in continuous contact.
These two parameter can be tuned for special applications (see
chapter 4.7 page 126).
Current temperature
Current temperature in the positioner housing The sensor is on the
electronics board.
The temperature display can be switched between _C and _F by
pressing the decrement key.
Minimum temperature (drag pointer)
and
Maximum temperature (drag pointer)
The minimum and maximum temperature inside the housing is
determined and stored continuously in a kind of drag pointer and can
only be reset in the factory.
