5-40 Function Relay
Array [8]
(Relay 1 [0], Relay 2 [1]
Option MCB 105: Relay 7 [6], Relay 8 [7] and Relay 9 [8]).
Select options to define the function of the relays.
The selection of each mechanical relay is realised in an array
parameter.

6-01 Live Zero Timeout Function
Option:
78
Function:
Function:
Enter the live zero time-out time period. Live zero
time-out time is active for analog inputs, that is,
terminal 53 or terminal 54, used as reference or
feedback sources. If the reference signal value
associated with the selected current input drops
below 50% of the value set in
parameter 6-10 Terminal 53 Low Voltage,
6-12 Terminal 53 Low Current,
parameter 6-20 Terminal 54 Low Voltage or
6-22 Terminal 54 Low Current for a time period
longer than the time set in parameter 6-00 Live
Zero Timeout Time, the function selected in
parameter 6-01 Live Zero Timeout Function is
activated.
Function:
Select the time-out function. The function set
in parameter 6-01 Live Zero Timeout Function is
activated if the input signal on terminal 53 or
54 is below 50% of the value in
parameter 6-10 Terminal 53 Low Voltage,
6-12 Terminal 53 Low Current,
parameter 6-20 Terminal 54 Low Voltage or
6-22 Terminal 54 Low Current for a time period
