SC-3 Controller 12
General
The DIP switch settings on the control are very important and
should be set to the appropriate settings prior to making any
adjustments to the control through the User Interface. The DIP
switch settings change the items that are available to be viewed
and / or adjusted in the User Interface.
If a DIP switch is changed while the control is powered up, the
control responds to the change in setting by returning the display
to the VIEW menu.
