Legend plate
The screened plastic overlay is provided with
translucent windows for the 16 channels. The
channel legend texts are applied on a drawing
film also square-ruled to form 16 text fields. The
drawing film can be inserted in a slot along the
left-hand edge of the front plate, see figure 27.
The front plate including the legend text film
and the screened plastic overlay are kept in place
by means of four finger screws.
The legend text may be written with a drawing
ink pen or a typewriter. Together with the an-
nunciator unit a sheet of drawing film compris-
ing three legend plates is delivered.
The channel text surface comprises 20 mm x
20 mm and the text area is ruled with four lines.
NOTE!
The starting point for the first line of the chan-
nel legend text is intended a few millimeters
from left in order not to cover the visual LED
indicator of the channel.
