Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user-programma-
ble pushbuttons to clear specific records are typical applications for these commands. Since the L30 responds to rising
edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.
Clearing records with user-programmable operands is not protected by the command password. However, user-program-
mable pushbuttons are protected by the command password. Thus, if they are used to clear records, the user-programma-
ble pushbuttons can provide extra security if required.
For example, to assign user-programmable pushbutton 1 to clear demand records, the following settings should be applied.
1.
Assign the clear demand function to pushbutton 1 by making the following change in the
