Push
SELECT
to return the unit to normal
operation.
The front panel display shows an "S" on the bottom
row as an indication that an internal scene is active.
NOTES ABOUT INTERNAL SCENE:
The RD122 continues to respond to control console
signals when the internal scene is activated. The
intensity of any given channel will be the "greatest
of" or "pile on" result of the internal scene and
console level setting.
If multiple RD series dimmers are connected as a
system (See CONTROL SIGNAL CONNECTIONS),
then a remote switch connected to the system can
activate system wide scenes or only scenes in
specific dimmers depending on how the remote
switch function is set in each dimmer. These scene
features give you the ability to use the dimmer for
house lights and other applications where it is not
practical to operate a control console.
CHASER OPERATION
The RD122 can operate chaser functions as a
"stand alone" unit with no control console present.
There are 7 factory set chase patterns embedded in
the unit software. There is also one pattern which
may be programmed by the user. The chase step
rate, chase step fade rate and chase intensity can
be set by the user for all chaser functions. Chaser
functions may be set to run continuously or as a
single occurrence. The number of steps (up to 32)
can be set for the programmable chase. The RD122
may be set to begin chaser functions at "power up"
or in response to a remote switch. A bounce option
can be imposed on a chase pattern. This results in a
pattern which runs in its normal sequence then runs
the same sequence backwards.
ACTIVATING A CHASE PATTERN
A chase stored in the RD122 is activated by
connecting together Switch Input and Switch
Common (Pin 6 and 7 of the 7-pin Phoenix
connector or pins 5 and 9 of either DB9 connector
depending on the rear plate design). The
connectors are on the rear of the dimmer. This may
be done via a remotely located switch. The
activated chase will remain active as long as a
closed circuit is maintained between these pins.
In addition to activating a chase, the RD122 can be
set to ignore the remote switch or use it to activate a
scene. In order to use the remote switch to activate
chase patterns you must enable that function as
follows:
1.
Push
MENU
3 times. The display will show the
message "MENU" on the bottom row.
2.
Push
SELECT
. The LCD will display one of
messages shown below.
3.
If "Not Used" or "Scene" appears on the bottom
row, push the
UP
or
DOWN
arrow buttons until
"Chaser" appears.
4.
Push
SELECT
to return the unit to normal
operation.
The Front panel display shows a "C" on the bottom
row as an indication that an internal chase is active.
SELECTING A CHASE PATTERN
You can select any of the 7 factory preset chase
patterns to run or create and run your own custom
pattern. Instructions for creating a custom chase
pattern are given further on in this manual.
A chase pattern is selected using the RD122 menu
system as follows:
