Way of creating a logical function “LG” which resolves JC executive relays tripping.
Access to the logical function configuration is realized by pressing
button, selecting “LG”
option and confirming it by pressing
button.
Further approach to configuration is showed in Fig. 42.
Attention!
In case of a change of the JP network address or deletion of the JP from the network, it is
necessary to configure the logical function “LG” again. Network addresses of unavailable JP
are denoted by symbol ”*” (e.g. the units which have their network addresses changed).
The default configuration of JC executive relays:
P1-P5 - connected with zone S1 (executive contact relay is closed after an arc fault
detection in zone S1),
P6-
S∑ - connected with zones S1, S2, S3 (executive contact relay is closed after an
arc fault detection in any zone).
JC is equipped with a configurable signal diode (RELAY EXE). Illumination of the LED can
be connected with JC executive relays tripping.
There are the following settings available:
”P1”... ”P6” – LED is lighted, when one of the relays P1...P6 is closed,
”P∑” – LED is lighted, when any relay is closed.
Configuration is available in submenu ”JC UNIT RELAYS”. Element denoted by symbol “L1”
should be selected by
button. Connection with one of the relays or LED signalization of
any relay tripping should be selected by
button.
In Fig. 42 illumination of the signalization diode is related to the tripping of the JC executive
relay, P1.
