 CLEAR RELAY
 RECORDS
Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user-
programmable pushbuttons to clear specific records is a typical application 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-
programmable pushbuttons are protected by the command password. Thus, if they are used to clear records, the user-
programmable pushbuttons can provide extra security if required.
For example, to assign user-programmable pushbutton 1 to clear demand records, apply the following settings.
1. Assign the clear demand function to pushbutton 1 by making the following change in the
