APPENDIX WTC 600 LP / MP
Service Handbook 08.2004
4.2.4 Multiselection
The multiselection allows to select various arguments simultaneously (for the purpose of this
paper, argument means any type of setting).
In the lowest line of the text display appears for that purpose a chain of "0" and "1". Each one of
these characters represents an argument. A "0" argument is inactive, a "1" argument is active.
A curser (flashing block) can be moved with the Í/ Î keys between the different characters
(arguments), and the corresponding description of the argument then appears in the
upper display line (e.g. name of operating mode). An argument can be activated/inactivated with
the Ï / Ð key.
The current setting of all arguments is accepted/stored with the Í key.
4.2.5 Numerical editing
The numerical editing is required to set the internal operating parameter and to enter the adjusted
values.
The procedure is the same as used for decade switches.
When numerical editing is called-in (e.g. via a menu), the name of the operating parameter/
adjusted value appears in the upper display line. The current value is displayed in the lower line.
A flashing block (cursor) always marks the figure which can be modified; this modification (new
setting) can be achieved with the Ï / Ð keys. Cursor displacement is achieved with the Í / Î
keys, so that other figures can be modified, too.
The displayed value is stored as new operating parameter when the Í key is actuated. The
ESC key allows to interrupt the procedure without any storage even if a new figure was entered.
4.2.6 Alphanumerical editing
The alphanumerical editing is required to set the message text for the uncommitted input failure
message. The procedure is the same as for numerical editing (see item 4.2.4), with the
exception that the Ï / Ð keys do not only allow to select numbers but also letters (capital/small)
and special characters.
4.2.7 Confirmations
Various menu activities require confirmations in order to avoid data entry errors. The user is
asked to confirm that modifications of operating settings/parameters and adjustments are
actually correct.
Confirmation is done with the Î key (select "yes") followed by the Í key. Otherwise, the
system will return to the level from which the function was called-in (e.g. menu) without any
consequences (no modification wil be stored).
