1 : Enabled
When this function is enabled and the bypass detects a loss of output current, for example an open external motor
disconnect or a zero frequency reference command for longer than 10 seconds, it will trigger a Load Lost fault and the
bypass will coast to stop, and digital outputs programmed to Damper Act Out [Z2-2x = 20] will open.
The bypass disables the Load Lost fault during emergency override operation.
