Arc fa

ult protection ZŁ-4A; (07.2019)

„E5”

not applicable.

A detection of an error is signalized by the central unit as well. The “ERROR” LED is

lighted, signaling relay contacts F8, F9 JC are closed. Detailed information about the error is

available on the page 6) ALARMS of the unit control panel.

12.5.

„Tripping” mode

In case when in a protected zone of the switchgear the fault arc has appeared, the pro-

tection ZŁ-4A will generate tripping signals to the circuit breakers, according to the estab-

lished regime. On the front panel of JW

“TRIPPING” LED is lighted. Information on the acti-

vation of the JW unit is also signaled by closing the contact of the signaling relay (the con-

tacts B1, B2 are closed).

Deleting “TRIPPING”

is realized by pressing

button on the front panel of an executive

unit for longer than 3s. The tripping of an executive

unit’s executive and signaling relay is

deleted. Deletion of activation or tripping of all elements of the protection system is realized

by pressing

button on the front panel of a central unit for longer than 3s.

Information about the protection system tripping is signalized on the front panel and also by

closing the contact of the signaling relay (contacts F5, F6 are closed) of JC (the default con-

figuration). Detailed information is available on the page 5) TRIPPING in control panel.

Using of central unit ZŁ-4A JC control panel

The central unit of the protection ZŁ-4A is equipped with a few optical signal LEDs and an

LCD display. Messages, which are important for a user, are presented by lighting LEDs. This

allows one to verify the state of the protection very quickly. In case of any abnormality it is

possible to take immediate actions. Detailed information is showed on LCD display. In case

of detecting any problems with the protection the signaling relay is tripped (the contacts F8,

F9 are closed). Below it is presented how to use the control panel of ZŁ-4A JC and some

typical messages generated on the front panel of the central unit are shown.
