breaker position injected via binary inputs is read out at the device and compared with
the actual breaker position. With 6MD665 this is easy to do with the control display.
The switching procedure is described in the SIPROTEC
®
system description /1/. The
switching authority must be set in correspondence with the source of commands used.
With the switch mode it is possible to select between interlocked and non-interlocked
switching. Note that non-interlocked switching constitutes a safety risk.
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 described 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
Centre If the device is connected to a remote substation via a system interface, the corre-
sponding 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.
3.3.7 Checking the process bus interface
The following is prerequisite for the operation of the process bus interface:
• The physical connection between the bay processing unit and the PCU has been
made.
• The PCU and its submodules have been configured.
• The SICAM HV modules process information was imported into DIGSI
®
, routed and
transmitted to the device.
• The PCU is switched on.
When commissioning the process control device, the connection to the PCU will be
made after about 20 seconds. In the process control device operational indications,
the PCU's fault indication (e.g. Fault_xxx) will be marked as Off.
