Temperature thresholds that are configured in the protection device can be checked by slowly approaching the
resistance value.
3.3.14 Trip/Close Tests for the Configured Operating Devices
Control by Local Command
If the configured equipment was not switched sufficiently in the hardware test already described, configured
equipment must be switched on and off from the device via the integrated control element. The feedback infor-
mation on the circuit breaker position injected via binary inputs is to be 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 non-
interlocked switching. Please note that non-interlocked switching can be a safety hazard.
Control by Protective Functions
Please bear in mind that a trip signal sent to the circuit breaker can result in a trip-close-trip event of the circuit
breaker by an external reclosing device.
DANGER!
A test cycle successfully started by the automatic reclosure function can lead to the closing of the
circuit breaker !
Non-observance of the following statement will result in death, severe personal injury or substantial property
damage.
Be fully aware that OPEN-commands sent to the circuit breaker can result in a trip-close-trip event of the circuit
breaker by an external reclosing device.
Control from a Remote Control Center
If the device is connected to a remote substation via a system interface, the corresponding switching tests may
also be checked from the substation. Please also take into consideration that the switching authority is set in
correspondence with the source of commands used.
