Description Profibus DP interface
S1.1
When using the external analogue input X11 AI 3/4, the switch S1.1 must be
in position AI 3.
S1.2
Switch for setting the position feedback via position transmitter potentiom-
eters/ RWG (option).
S1.2 = V: If the actuator is equipped with a potentiometer without RWG, this
switch must be in position ‘V’.
S1.2 = mA: Switch may only be in this position if an RWG is installed in the
actuator.
If the actuator is equipped with an RWG (0 – 20 mA or 4 – 20 mA), this
switch must be in position ‘mA’.
S2/S3
Rotary switches for Profibus address setting.
These two switches are used to set the address of the actuator within the
Profibus DP network. Only addresses from 0 to 125 may be allocated.
S2
Rotary switch for setting the unit digit.
S3
Rotary switch for setting the tens digit.
S4
Switch for setting the end position seating in end position CLOSED.
(In end position OPEN, switching off is always via limit seating)
This switch is used to inform the Profibus DP board about the type of
seating is to be used to operate the actuator in end position CLOSED (limit
seating or torque seating). The end position seating is set in the factory
according to the details given in the order.
The setting of the end position seating in end position CLOSED
must be the same on the Profibus DP board (switch S4) and on
the logic board (switch S1-2, figure H, page 17).
S4 = LIMIT: If the switch is in position ‘LIMIT’ (left, no dot visible), the actu-
ator is in limit seating for end position CLOSED.
S4 = TORQUE: If the switch is in position ‘TORQUE’ (right, dot visible), the
actuator is in torque seating for end position CLOSED.
