Programming of number series
The system allows to program a series of numbers (up to 99) on the display unit, different from the
standard one (1-12 or 1-24). This is particularly useful when there are more than 24 call numbers, with
several independent display units, or when it is necessary to have progressive numbers that do not start
from number 1.
To program the new series of numbers, follow this procedure:
(1-2) With deenergized display unit, connect terminals 7-8-4B1 with a jumper.
(3-4-5-6) Insert the terminal block and energize. Then, with the erase pushbutton (PA), select on the
display unit the number immediately before the one from which the desired series should begin (e.g.
select No. 24 to program number series 25-48).
(7-8) Deenergize and remove the jumpers that connect terminals 7-8-4.
(9) Insert the terminal block again and energize the system.
If there are repeater display units, the programming of numbers must be carried out only on the main
display unit.
