12.6 - RelayCfg (Relay Configuration)
To associate one of the Output Relays to one or more functions: enter the menu “R/W Set”, select “Relay
Cfg”, select the “Relay #” to be programmed, select “Link”; at this stage the list of the available functions is
displayed. Scrolling the list by the “+” and “
- ” keys the function is selected and then assigned by the key
“Enter”. The assignation is confirmed by the function indication that switches from blinking to steady.
Any of the Output Relays can be programmed to work in two different modes:
N.D. Normally Deenergized Relay is energized on trip of the associated functions
N.E. Normally Energized Relay is deenergized on trip of the associated functions
Programming of working mode is made as above selecting “OpMode” instead of “Link”.
