Operation 4
Setting up a run 4.3
If Y is selected, no more phases will be added and the alarm question will be shown, see
below.
If N is selected, the next phase number for the program will be shown on the display
together with zero values for all parameters. Program the next phase according to
Setting voltage, current and power‚ on page 32 and Figure 4-1 step 4. Up to nine phases
can be programmed.
Choosing alarm
The alarm can be set separately for each phase. The following question is shown:
Alarm Phase 1? Select Yes (Y) or No (N) with and confirm with set enter.
If Y is selected in a 4 phase program this will be indicated by changing from - - - -
to 1 - - - after “Phase” on the lower row in the display. Then you will be asked about an
alarm for the next phase. After answering Y or N for the last phase, the start position in
the SET mode will be shown. If alarm is selected for a phase a small “A” appears on the
right of the phase number, i.e. 2 2
A
.
Back to start position
The program is now back to the start position in the SET mode with the program
number flashing. It is possible to go back to this position at any stage during
programming in SET mode by pressing exit or STOP. Note that the program is
automatically saved with all choices that have been confirmed by set enter when exit
or STOP is pressed. If a phase containing invalid values (zeros) is left, this phase will be
deleted.
Disabling the start current check
See Optional programming‚ on page 34 if you want to use this feature.
Editing a program
Changing a parameter value
To change a parameter value, move to the start position in SET mode by pressing exit
or set enter and choose program number as described in Choosing a program‚ on
page 28. If the programming mode (step or gradient) is changed it will be changed for
all the phases within the program.
Select phase number by and move in the program with set enter to the value to
be changed. Change with and confirm with set enter. Press exit.
Inserting and deleting a phase
Inserting and deleting a phase is described schematically in Figure 4-4.
Note that you must first enter a phase before it can be inserted or deleted:
1 If needed, change program number by entering the start position in SET mode with
set enter or exit, changing the number with and confirming by set enter.
2 Bypass the mode question with set enter.
