Pro-Bel Ltd Technical manual
The same source association can be assigned to more than one button. The same
destination association can be assigned to more than a single group of 8 buttons.
Only one <SOURCE> button lamp per destination association assigned will be lit.
The levels controllable can be assigned to Type 1 panels via Editors.
The <level breakaway> buttons operate on a toggle on, toggle off basis where the
tally indicated on the panel is dictated by the number of level buttons on the
panel.
For type 1 panels with no level buttons the tally indication for each destination
association is for the first controllable level with an assigned destination for the
assigned destination association. The source routed on that level is first compared
against the source on the same level of the source association assigned to the last
<SOURCE> button pressed. If a match is found then this buttons lamp is lit,
otherwise, the other buttons are checked in the same way until a match is found.
The first match results in that <SOURCE> button lamp being lit.
For type 1 panels with level buttons the tally indication is for the current most
significant active, controllable level (level 1 being the most significant level) .
Active levels are indicated by the level button LED being illuminated . Only
controllable levels can be active
(It
is not possible to turn all level buttons off
unless no levels are controllable).
If the current source association routed is assigned to more than one <SOURCE>
button then the tally indicated will be for either the last <SOURCE> button pressed
or the first button that source association is assigned to.
To have full 8 level breakaway control from only 4 physical level buttons a <ALT­
LEV> button is required. This function can be assigned to any button on the panel
by assigning the level shift association to a button position on the source keypad.
More than one button can be assigned as a <level shift> button.
