DNP 3.0
The feeder and motor manager supports communication using
DNP3.0 protocol.
The following DNP3.0 data types are supported:
•
binary input
•
binary input change
•
double-bit input
•
binary output
•
analog input
•
counters
Additional information can be obtained from the DNP3.0
Device Profile Document for VAMP 257.
DNP3.0 communication is activated via menu selection. RS-485
interface is often used but also RS-232 and fibre optic
interfaces are possible.

Arc protection (option)
The optional arc protection card includes two arc sensor
channels. The arc sensors are connected to terminals X6: 4-5
and 6-7.
The arc information can be transmitted and/or received
through digital input and output channels. This is a 48 V dc
signal.
Connections:
•
X6: 1
Binary input (BI)
•
X6: 2
Binary output (BO)
•
X6: 3
GND
•
X6: 4-5 Sensor 1
•
X6: 6-7 Sensor 2
The GND must be connected together between the GND of the
connected devices.
The binary output of the arc option card may be activated by
one or both of the connected arc sensors, or by the binary input.
The connection between the inputs and the output is selectable
via the output matrix of the device. The binary output can be
connected to an arc binary input of another VAMP protection
relay or manager.
