Notes on the Infor-
mation List
The most important information of the device is briefly explained in so far as it cannot
be interpreted in the following information lists or described in detail in the foregoing
text.
„>Sync. Start MC“ (No. 2905)
Binary input which enables direct initiation of the synchronism check with setting pa-
rameters for manual close. This initiation with setting parameter for manual close has
always precedence if binary inputs „>Sync. Start MC“ (No. 2905) and „>Sync.
Start AR“ (No. 2906, see below) are activated at the same time.
„>Sync. Start AR“ (No 2906)
Measuring request from an external automatic reclosure device. The parameters of
synchronism check set for automatic reclosure are valid here.
„Sync. req.CNTRL“ (No 2936)
Measurement request of the control function; this request is evaluated on event-trig-
gered basis and only generated if the control issues a measurement request.
„Sync. release“ (No 2951)
Release signal to an external automatic reclosure device.
2.16.3 Settings
Addresses which have an appended "A" can only be changed with DIGSI, under Ad-
ditional Settings.
