The assignment of output relays 1 - 4 can be changed
by pressing <+> and <-> pushbuttons. The selected
assignment can be stored by pressing pushbutton
<ENTER> and subsequent input of the password. By
pressing pushbutton <SELECT/RESET>, LED I> lights
up red. The output relays can now be assigned to this
current element as tripping relays.
Relays 1-4 for the other elements are selected in the
same way as described before. The assignment mode
can be terminated at any time by pressing the
<SELECT> pushbutton for some time (abt. 3 s).
Note:
•
The function of jumper J2 described in general de-
scription "MR Digital Multifunctional Relays" has no
function. For relays without assignment mode this
jumper is used for parameter setting of alarm relays
(activation at pickup or tripping).
A form is attached to this description where the set-
ting requested by the customer can be filled-in.
