Freedom Sequence Operational Concepts

Auto-Detection of AC Input Source (Shore/Gen)

The Freedom Sequence power manager can be wired to a transfer switch that is connected to either a shore power or a generator power source. When AC voltage is detected at the input terminal of the Freedom Sequence, the AC source is assumed to be coming from shore power if the B+ signal is not active. Freedom Sequence detects the B+ signal two ways: via the Xanbus Automatic Generator Start (AGS) on the Xanbus network or through the presence of 12 volts on the B+ signal wired to the DC auxiliary connector port. The Freedom Sequence power manager assumes a generator power source is On when a high B+ signal is detected from either source.

IMPORTANT: The Freedom Sequence power manager automatically sets a ceiling on the current that’s coming from either input sources. The goal of this ceiling (current clamp) is to avoid current draw in the RV from tripping the input source’s breaker when an overload occurs within the RV's power system. Instead, the power manager’s AC Load Shedding (see next page) logic will determine which loads to disconnect within the power system while staying within the current clamp value. The current clamp is always 80% of the breaker rating of the input source. For example, if the shore breaker in an RV Camp is set to 50 amps then, the current clamp is 80% of 50, which is 40 amps. However, when BRK Derating is disabled, the current clamp is 100% of the breaker rating. See “Breaker Derating” on page 22.

Auto-Detection of AC Input Source Type (1-Ph/2-Ph)

The AC source connected at both Line1 and Line2 of the Freedom Sequence power manager can be either Split phase or Single phase.

•Single phase is determined when 120 volts is measured between Line1-to-Neutral or Line2-to-Neutral or both, and there is no phase difference between the voltages measured.

•Split phase is determined when 240 volts is measured between Line1and Line2 and that the voltages are found out of phase by more than 100 degrees.

Loading of Shore/Generator Breaker Ratings

The Freedom Sequence has the ability to automatically change the breaker settings from shore power (Shore Breaker) to generator power (Generator Breaker) when it detects the B+ signal. At any time if the B+ signal goes low, the Freedom Sequence will instantly switch to the shore breaker setting.
