5.2.3 Reset
MRR1 has the following 3 possibilities to reset the display as well as the output relays at jumper
position J3 = ON.
(see also chapter 4.2 of description "MR-Digital Multifunctional Relays".
Manual reset
by pressing push button <SELECT/RESET> for some time (approx. 3 seconds.)
Electrical reset
by applying aux. voltage to C8/D8
Software reset
software reset has the same effect as the <SELECT/RESET> push button. Please also
refer here to the communication protocol of RS 485 interface.
Resetting the display is only possible when there is no pickup anymore (otherwise signal "TRIP"
will still remain in the display and the relays remain activated). Resetting the relay does not change
the preset parameters.
