PRODUCT SETUP
The power cut-off is therefore:
power cut-off= (
= (
× 0.02 pu × 1.0 V × 100 A × 13811.2 V) / 66.4 V
= 720.5 watts
Any calculated power value below this cut-off does not display. As well, the three-phase energy data do not accumulate if
the total power from all three phases does not exceed the power cut-off.

RESET UNAUTH ACCESS
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 L60 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
