4.6.8 RESET PROFILE
This menu allows a way of stopping and resetting a profile currently loaded and running on the
loop indicated. It returns the display to the PROFILE SELECTION menu so that another profile
may be assigned to the loop. In this way a channel can be removed from ramp and soak mode by
resetting the current profile and making the PROFILE = NONE assignment.
An example of the RESET PROFILE display follows :

In this example profile A is running on channel 5.
Press BACK to return to the PROFILE TIME display.
Press NO to return to the SINGLE LOOP display.
Press YES to reset the profile assignment. The "?" will become "=". Press ENTER to return to the
PROFILE SELECTION menu.
The 12LS R/S program also supports an external contact to reset the R/S program. This function is
programmable in the R/S program(See Section 4.7.6 Edit External Reset). The external reset input
is programmable to any of the eight digital inputs. Any program that is assigned to that input will
be reset when the input is forced low by connecting it to the digital ground. The external reset is
disabled when no input is assigned to it.
