Minimum AC
Frequency Delay
Displays as:
Min Hz Delay:
This parameter sets the time delay
value, in AC cycles, for the “AC
Frequency Low” (0010) fault. If
the grid frequency remains below
the minimum AC frequency
setting (Min AC Freq) for the
duration of this delay period, the
fault is then triggered. The limits
of this parameter are restricted by
UL 1741 requirements.

AC Auto-Clear Delay
Displays as:
AutoClear
Delay:
This parameter sets the time delay
value, in seconds, for the Auto-
Clear feature corresponding with
the AC Voltage and Frequency
(0013, 0012, 0011, and 0010)
faults. The AC Voltage and
Frequency must remain within
their respective limits before an
Auto-Clear can occur. The limits
of this parameter are restricted by
UL 1741 requirements.

Modbus ON:
This parameter sets the protocol
used by the serial port (J1004) on
the CCU2. The serial protocol can
be set to either Modbus ON (1) or
to Modbus OFF (0) [Xantrex
protocol].
