to »50P[1] . ExBlo1« (or the one assigned to »50P[1] . ExBlo2«) is “Active” then the

Synchrocheck Settings
For proper operation of the Synchrocheck module, settings have to be made in three
di󰊞erent menu branches:
•
In [Device Planning], make sure that »Sync . Mode« is set to “Use”.
•
• In [Protection Para / Global Prot Para / Intercon-Prot / Sync], there are several•
settings to be checked. In particular, assign a close request signal to »Sync .
BkrCloseInitiate«, for example the signal “QA1 . Sync CLOSE request” (with “QA1”
being only an example, the switchgear designation can be de󰊟ned using the Page
Editor application, see ╚═▷ “3.12 Single-Line Diagram”).
•
In [Protection Para / Set 1 / Intercon-Prot / Sync / Mode / Times], check the time-
•
related parameters, then select the synchronization mode:
◦
»Sync . SyncMode« = „System2System“ – synchro-check between two systems,
◦
stand-alone, no breaker info needed, or
◦ »Sync . SyncMode« = „Generator2System“ – synchronizing a generator to a◦
system, breaker close initiate needed.
• In [Protection Para / Set 1 / Intercon-Prot / Sync / DeadLiveVLevels], check the•
voltage thresholds that are used as synchronization criteria. In the same way, check
the settings in [Protection Para / Set 1 / Intercon-Prot / Sync / Conditions]. Finally, in
[Protection Para / Set 1 / Intercon-Prot / Sync / Override], specify whether overriding
shall be “Active” or “Inactive”.
• In [Control / Bkr / QA1 / Synchron Switchg], set »QA1 . Synchronizm« to “Sync . In-•
Sync Allowed”, so that the switchgear “QA1” gets a “closing allowed” signal from the
Synchrocheck module.
5.2.10
Trip Manager and Switchgear Con󰈛guration 1
Enter the menu [Control / Bkr / Qxx / Trip Manager] for every switchgear device “Qxx” that
is available for your protection device.
Set the parameters for latching, the acknowledgment signal (if »Latched« is set
to “Active”) and all the other settings that are relevant for your application. In
particular, assign the trip commands of the required protection functions to any of the
parameters »Trigger1«, »Trigger2«, ...
This way you specify all the trip commands that shall lead to a trip of the Breaker “Qxx”.
Enter the menu for the binary output (i. e. the Relay Output) that shall be used with
the Breaker “Qxx” and assign the trip command »Qxx . TripCmd« to the respective Relay
Output. This is depending on your hardware con󰊟guration, of course; the setting might
be, for example: [Device Para / Relay Outputs / RO Slot X2 / RO 1] »Assignment 1« =
“Qxx . TripCmd”
