Pro-Bel ltd Technical manual
Each button operates in a toggle on/off manner with the level active indicated by
an illuminated button. Unless otherwise stated each button toggles the state of
one level only. Only levels that are controllable can be toggled on or off.
On occasions when more controllable levels are assigned to a panel than there are
level buttons then the last level button controls the excess levels, i.e. if the
controllable levels for a 4 level button panel were defined as 1, 2, 3,4,5,6 then
level 1 to 3 would be assigned to first three level buttons respectively, and the
fourth level button would control levels 4, 5 and 6.
Single levels or all levels can be turned off, if required, via the editor terminal.
Alt-Iev
The level shift function is used on panels with only four level buttons to allow
individual control of all eight levels .
It
operates in a toggle on/off manner with an
LED used to indicate the level shift - when the LED is off then levels 1 to 4 are
controllable and when the LED is on levels 5 to 8 are controllable.
The level shift function is button programmable on all panel types (BPX and X-Y) in
the same way as the protect feature. Any source or destination button can be
configured as a level shift button and more than one source or destination button
can be configured as a level shift button.
Clear
This key is used as a source preselect or destination clear key and is always
assigned to the bottom right key on the keypad .
Controllable destinations
This applies to X-Y panels only. The user can configure any destination association
to be controllable from a given X-Y type panel.
Destination buttons
Button per destination type keypads and dial up keypads (multiple button
presses) are available.
Pressing a destination button or a sequence of destination buttons selects a
destination association index which references one destination per level. This
gives the user the opportunity to make selections on different destinations.
