The selection “Cycle single phase” means that, in a series of Open commands, the first Open command
will be issued on phase A; next Open command will be issued on phase B; next Open command will be
issued on phase C. With further Open commands the cycle will be repeated.
The selection “Cycle two phases” means that, in a series of Open commands, the first Open command
will be issued on phases A and B; next Open command will be issued on phases B and C; next Open
command will be issued on phases C and A. With further Open commands the cycle will be repeated.
The selection “Cycle all” means that, in a series of Open commands, they will be: Phase A; Phase B;
Phase C; Phases AB; Phases BC; Phases CA; Phases ABC. With further Open commands the cycle will
be repeated.
- With the “Sequence” selection, the user can edit the desired test sequence. This gives the following
possibilities:
. Issue a sequence of Open and Close commands: up to 200 commands can be programmed. With this
selection it is possible to program the delay between OC commands: delay range 30 to 999 s.
. In case of four coils, program any series of Open commands;
. Program a COC sequence.
. Execute a test that simulates the lack of Auxiliary Voltage.
To this purpose, the following window is opened.
. Time delays and durations are independently set for each cycle; these values are independent with
respect to those selected for the single test: see here after.
The user must take care of defining a proper sequence, in terms of timing and Open-Close sequence.
Add and Delete commands help editing the test sequence. The Delay selection must be set between two
commands: remember that the CB cannot be driven with timings less than 30 s.
- The Recording Options command opens the following window.
