Trip/Close Tests for the Configured Operating Devices

Control by Local Command
If the configured operating devices were not switched sufficiently in the hardware test already described, all
configured switching devices must be switched on and off from the device via the integrated control element.
The feedback information of the circuit breaker position injected via binary inputs is read out at the device and
compared with the actual breaker position.
The switching procedure is described in the SIPROTEC 4 System Description. The switching authority must be
set according to the command source used. The switching mode can be selected from interlocked and nonin-
terlocked switching. Please note that non-interlocked switching can be a safety hazard.
Control by Protective Functions
For OPEN-commands sent to the circuit breaker please take into consideration that if the internal or external
automatic reclosure function is used a TRIP-CLOSE test cycle is initiated.
