Figure 5-2: VP-2040 Relay Output Capability

The VP-2040 provides two relay control modes. They are Remote
control and Local control modes. The action of relay is different in
these two modes. So, users should distinguish the relay is in Remote
control mode or in Local control mode at first.
The default control mode of the product is Remote control. Users can
change the mode through communication or via front panel.
 Remote Control mode (external) - The relay is controlled
by a PC or PLC by using commands through Modbus RTU
communication protocol.
 Local Control mode (internal) - The relay is controlled by
one of the electrical parameters inside the meter, which
serves as the response to the control alarm conditions of a
set point.
Once the relay has been in the remote control mode, even though
the local control conditions have been set, the relay will not operate.
Therefore for any set point and alarm that trigger action need that the
relay mode must be set at local control mode.
