to execute all switchgear interlocking checks and to state if switching is permitted
or not.
In additon to this, it is checked if maximally one synchronisation function (measuring
phase) is active.
– Control direction:
Control command = ON: Continue with synchronisation check.
Control command = OFF: Continue with control phase (no synchronisation
required).
– Synchronisation check:
Checks whether the control device concerned shall be switched on synchronised
or evaluation of the number of input messages
´!6\HIIµ
= ON.
– Analysis of the operating mode
Evaluation of the input indications of the selected block.
Table 2-5
Start conditions check phase, SYNC function module selection

Start conditions check phase, operating mode analysis
• Measuring: This phase executes the synchronisation subfunction.
This phase is coordinated by means of input indications:
–
´!6\0HDVµ
, start/stop of measurement
–
´!6\GLU&2µ
, bypassing
–
´!6\EORFNµ
, block switching enable
