Setting the time synchronization

The calendar clock can run locally or be synchronized with external IRIG-B time standard signal, RSM clock or IEC60870-5-103. This is selected by setting as follows:

Setting the protection function

To set the protection schemes, scheme switches and protection elements, do the following. Protection elements are the measuring elements and timers.

Note: Depending on the selected protection scheme and scheme switch setting, some of the scheme switches and protection elements are not used and so need not be set. The protection function setting menu of the GRZ100 does not display unnecessary setting items. Therefore, start by setting the protection scheme, then set the scheme switch, then the protection elements. As a result of the above, note that some of the setting items described below may not appear in the actual setting.
