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.
´!6\QF6WDUW0&µ (FNo. 2905)
Binary input which enables direct tripping of the sychnonism check with setting param-
eters for manual close. This tripping with setting parameter for manual close has
always precedence if binary inputs ´!6\QF6WDUW0&µ (F.No. 2905) and ´!6\QF
6WDUW$5µ (F.No. 2906, see below) are activated at the same time.
´!6\QF6WDUW$5µ (FNo. 2906)
Measuring request from an external automatic reclosure device. The parameters of
synchronism check set for automatic reclosure are valid here.
´6\QFUHT&175/µ (FNo. 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.
´6\QFUHOHDVHµ (FNo. 2951)
Release signal to an external automatic reclosure device.
