11.9 - Task Assignment to Relay 1 and Relay 2:
Parameters (PAr): Voltage ( ULn ), current ( ILn ), total current ( ILt ), total harmonic distortion belong to
Voltage ( thdV ), total harmonic distortion belong to Current ( thdI ), power factor ( PF ), voltage Unbalance
( U Un ), current Unbalance ( I Un ), digital input ( dI n ) and off ( OFF ).
Function (Fun): Functions to be applied for parameters: if greater than value ( hI ) and smaller
than value ( LO ).
Value(Val): The value to be set for the parameters.
Note1: The hysteresis value is fixed at 5%.
Note2: The task assignment of relay 2 is assigned in the same way as relay 1. While in menu for relay 2
assignment ,The enterance should be done from the figure-68.
Note3: To use the digital input parameter, 9V-24DC energy should be applied from the enterance of input
to the device. In these parameters if the relay is wanted to be pulled HI function; or if it is wanted to be
pulled while the energy is not available LO function should be chosen. The change of the voltage at the data
input should be minimum at one second(1Hz)
Example: When the voltage rises above 250V, switch on relay 1. Parameters (PAr)=ULn, function (fun)=hl
and value (VAL)=250V should be set. After the relay 1is set like that; if one of the voltage values rises above
250V;relay 1 pulls out(The contact leads become short-circuited) When the all values od voltage are below
%5 of 250V;the relay is deactivated (contact leads become open circuit)

To assign the task to relay 1, press the set key, when
figure-77 is on the screen. There are 3 settings; these are
Parameter (PAr), Function (Valued) and Value (VAL).
Press the right key to move the point (.) to the parameter.
Press the down key to bring up the desired parameter.
Then press the right key to move the point (.) to the
function. Press the down key to set the function to low or
high set. Press the right key to move the point (.) value.
Press the down key to enter the desired value. Then when you press the set key, the task will be assigned to
relay 1 and Figure-67 comes to screen. You can scroll through the parameters in the menu by pressing the
right button or you can exit the menu by pressing the Esc key.
