dpV1 interface
the module consists of a single Pcb that is installed inside the actuator housing. It is connected
to the EPI
2
base card via a flat cable. the internal wiring connects the Profibus data lines to the
actuator terminal board.
6.1 on board indication
six LED’s are mounted on the EPI
2
DPV1 interface to give the following indications for field
service. LED’s indications are active only when jumper JP2 is closed.
DL1 (red)
Internal comm. error:
On when the internal communication of the
interface card is not working properly.
Off when the all communication is correct.
DL2 (red)
fail safe action in progress: On when a fail safe action is in progress due to a
communication fault on the Profibus line.
Off when the Profibus communication is correct.
DL3 (green)
slave ready:
On when the interface is ready to communicate to
the Profibus line.
Off when the interface is not ready.
DL4 (green)
reserved
DL5 (green)
Profibus:
On when Profibus communication has been
established and the interface has entered in
Data_EX state.
DL6 (green)
Power:
On when the interface is correctly powered.
