the EPI
2
DPV1 board is equipped with a set of
switches to allow the operator to configure the
Profibus address.
furthermore two soldering pads are available
to connect the Profibus termination circuit to
be used in case that the external termination is
not available.
to perform the local setting on the EPI
2
DPV1
board, it is necessary to follow carefully the
procedures explained in the EPI
2
quarter-turn
electric actuator IOM at chapter 6: ‘actuator
settings and configuration’.
12.1 profibus address setting
Profibus address is configured by means of the
switches indicated in the figure and located
on the EPI
2
DPV1 interface soldering side,
direct accessible when the control unit cover is
removed. to enter a new Profibus address the
EPI
2
actuator needs to be powered.
configuration procedure:
• Move the dip switch ENA-CFG to the ON
position: the cfG_On LED is turned On
to indicate that the actuator is entered in
configuration mode
• Set the new Profibus address on the rotary
switches unIt and DEc and on the dip switch
HunDr. E.g. address 028 corresponds to:
- HunDr. on Off position
- DEc. on position 2
- unIt on position 8
• Press the push button ENTER to confirm the
new settings: if the new address is correct the
acQ_cfG LED is turned On
• Move the dip switch CFG_ENA to the OFF
position to exit from configuration mode: the
cfG_On LED is turned Off and the OM9
Profibus DPV1 restarts with the new address.
It is not required to power down and start up
the actuator.

12.2.a profibus termination on board code
de5687r00e
On board termination is located on the side of
the EPI
2
DPV1 module as shown in the photo
below. the termination is activated by two
soldering paths indicated with JP12 and JP13:
On default the soldering paths are left open and the
termination is not active.
to activate the on board termination both the
soldering paths must be closed as indicated.
