Lower the VOLTAGE CUT-OFF LEVEL and CURRENT CUT-OFF LEVEL with care as the relay accepts lower sig-
nals as valid measurements. Unless dictated otherwise by a specific application, the default settings of “0.02 pu” for
CURRENT CUT-OFF LEVEL and “1.0 V” for VOLTAGE CUT-OFF LEVEL are recommended.
5.2.3 CLEAR RELAY RECORDS
PATH: SETTINGS
PRODUCT SETUP
CLEAR RELAY RECORDS
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 D60 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
