Automatic initialization (see chapter 3.6, page 72)
By selecting “Strt” and pressing the increment key
for at least
5 seconds, automatic initialization is started. The initialization process
is displayed by “RUN 1” to “RUN 5” (see figure 3-35, page 83 to
figure 3-38, page 86).
Manual initialization
By selecting “Strt” and pressing the increment key
for at least
5 seconds, manual initialization is started. The manual initialization
process is described in chapter 3.6.3, page 76 and chapter 3.6.6,
page 81.
.
NOTE
If the positioner has already been initialized, for INIT A and INITM it is
possible to transfer it to its non-initialized state without changing the
remaining parameters by pressing the decrement key for 5 s.
Current range of the setpoint
The selection of the current range depends on the connection type.
“0mA” (0 to 20 mA) is only possible in three-/four-wire connections (see
figure 3-23, page 64).
Setpoint direction (see figure 4-8, page 101)
The setting of the setpoint direction serves to reverse the direction of
action of the setpoint. It is used mainly for the split range mode and in
single-acting actuators with the safety position “up”.
Split range start (see figure 4-8)
and
Split range end (see figure 4-8)
The parameters “8.SPRA” and “9.SPRE” in connection with the
parameter “7.SDIR” serve to restrict the active setpoint range. In this
way split range tasks can be solved with the following characteristics.
S rising / falling
S falling / rising
S falling / falling
S rising / rising
