CLEAR RELAY RECORDS
Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program-
mable pushbuttons to clear specific records are typical applications for these commands. Since the N60 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
