PATH: SETTINGS  FLEXLOGIC  NON-VOLATILE LATCHES  LATCH 1(16)
The non-volatile latches provide a permanent logical flag that is stored safely and will not reset upon reboot after the relay
is powered down. Typical applications include sustaining operator commands or permanently block relay functions, such as
Autorecloser, until a deliberate interface action resets the latch. The settings element operation is described below:
• LATCH 1 TYPE: This setting characterizes Latch 1 to be Set- or Reset-dominant.
• LATCH 1 SET: If asserted, the specified FlexLogic operands 'sets' Latch 1.
• LATCH 1 RESET: If asserted, the specified FlexLogic operand 'resets' Latch 1.
