5.9.1 Reset
All relays offer the following three possibilities to reset
the display of the unit as well as the output relay at
jumper position J3=ON.
Manual Reset
•
By pressing the push button <SELECT/RESET> for
some time (about 3 s)
Electrical Reset
•
Through applying auxiliary voltage to C8/D8
Software Reset
•
The software reset has the same effect as the
<SELECT/RESET> push button (see also communica-
tion protocol of RS485 interface)
Automatical Reset
•
At each excitation of a protection function
The display can only be reset when the pickup is not
present anymore (otherwise "TRIP" remains in display).
During resetting of the display the parameters are not
affected.
5.9.2 Erasure of fault storage
To delete the trip store, the push button combination
<SELECT/RESET> and <->, has to be pressed for
about 3s. The display shows “wait”.
5.9.3 Erasure of disturbance recorder
By repeated setting of the parameter “number of re-
corded events”, it is possible to delete data of the dis-
turbance recorder. The LED FR will then expire (refer to
chapter 5.5.1).
Alternatively, it is also possible to clear the memory
space of the disturbance recorder by means of the
software "HTL/PL-Soft4".
