10. Starting up
10.1. Registration of bay units
Once the mounting of the optic elements of the arc fault protection ZŁ-4A is completed
and all the connections are checked, one is allowed to start up the device. One should also
keep in mind that during the start-up process unnecessary tripping signals may be generat-
ed.
After supplying all units with 24 V DC it is possible to start the device configuration. The
first stage is to assign each bay unit the unique network address ranged 1..99 and each ex-
ecutive unit the unique network address ranged 1..5. It is recommended for the network ad-
dress to be adequate to the bay number in which the bay unit is installed. Then, it is easier to
localize the bay unit during work with the central unit operating panel. For more details on the
network addresses check point 11.3 of the following manual.
Next step is to register all bay and executive units in the central unit. It is necessary for a
proper operation of the protection system. In order to register bay and executive units in the
central unit please follow point 13.3.7 - Fig. 44
, by choosing option “SCAN & INSTALL”.
Then, this step is made automatically by the central unit. Each network address of respective
bay and executive units can be found on the page 1) JP/JW UNITS in
“REGISTERED” Sub-
menu. There is a possibility to add or remove a single bay or executive unit (more details in
Attention!
Assigning IP address to a bay/executive unit is not equivalent to its registration in the system.
Registration has to be done in the central unit. An unregistered bay or executive unit is not
fully functional.
A change of a bay or executive unit IP address means that it has to be registered in the sys-
tem again with a new IP address. In case when an unregistered bay unit will detect an arc
fault the tripping algorithm is only partially executed.
After configuration of the protection system one needs to check the number of the registered
units and the number of units present in the network. It is possible on page 1) JP/JW UNITS.
The number of registered devices should be the same as the number of assembled units.
