When a new Degree Master is added to the SC 255 system, or when there has been
a service replacement, you must use the "Locate Procedure" so that the SC 255 will
recognize the Degree Master.
Follow this procedure:
1) Enter an address from 1 to 99 that is unique among the Degree Masters in the
system.
2) Select Locate and press ENTER or click with your mouse.
3) A message will appear requesting that you press the service pin.
4) You have 10 minutes to go to the particular Degree Master you are working
with and depress the service pin. The service pin (or button) is located beneath
the upper right corner of the square white label on the Degree Master.
5) Use a pencil (or other instrument that will fit through the access hole) to
depress the service button and keep it depressed for five seconds.
It will take the SC 255 from 10 to 15 seconds to complete the location process, after
which a message box will appear on the SC 255 telling you that the process has been
successful. This process must be repeated for each new or replacement Degree
Master.
After starting the locate procedure from the SC 255 keypad, it is possible to activate
the service pin from the Degree Master's display. Press and hold both buttons for 3
seconds. When the Degree Master enters the service mode, the display will change to
"RS" with an up arrow on the left and a down arrow on the left. Pressing the lower
button will now activate the service pin. The down arrow will change to an asterisk as
confirmation. Be careful not to press the upper button. Doing so will reset the Degree
Master.
After the Locate procedure, Select Init and press ENTER or click with your mouse.
The initialization procedure, during which configuration data is copied from the AKC
55 to the Degree Master, will take about 10-15 seconds.
Wink All Degree Master is a toggle (first ENTER turns on, second turns OFF) that
will cause all the Degree Masters on the network to flash their node numbers repeat-
edly. If a unit does not wink its number, test its function with the handheld remote
control (in accordance with the Degree Master manual). If the unit is functioning to
control the fixture, troubleshoot its network connection and addressing.
To configure Board & Points for Danfoss VLT and AKD variable frequency drives,
select the variable speed drive icon (fourth from the left) on any Configure Board &
Points Other Controllers screen and press ENTER. The screen looks like this (though
you see only one here, all configured VLT drives will be listed.)
