1) Following three unsuccessful restarting attempts, the device is put out of operation.
2) DOK = "Device OK" = readiness relay drops out; protection and control functions are blocked.
3) There is a separate power supply for extension I/O board.
Group Indications
Certain indications of the monitoring functions are already combined to group indications. These group indica-
tions and their composition are stated in the Appendix
Alarm Sum Event is only issued when the measured value monitoring functions (8101 MEASURE.
SUPERV) are activated.
