Lower the VOLTAGE CUT-OFF LEVEL and CURRENT CUT-OFF LEVEL with care as the relay accepts lower signals
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-program-
mable pushbuttons to clear specific records are typical applications for these commands. Since the G60 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
SETTINGS PRODUCT SETUP
CLEAR RELAY RECORDS menu:
CLEAR DEMAND: “PUSHBUTTON 1 ON”
2. Set the properties for user-programmable pushbutton 1 by making the following changes in the
