Reconnect Margin

When a load circuit connected to either Line1 or Line2 is shed by Freedom Sequence to avoid an overload condition, Freedom Sequence stores in its memory the current that load circuit was drawing before it got shed (that is, Last Load Shed current).

The Freedom Sequence continuously checks for the Headroom Current1 and compares it with the Current To Reconnect value for the circuit. If the Headroom Current is more than the Current To Reconnect for a time- period that is more than the Connect Sequence Delay setting, Freedom Sequence will reconnect that circuit.

Current To Reconnect is calculated based on Reconnect MGN and Last Load Shed.

For example, if Circuit1 was set to a reconnect margin of 20% and the Last Load Shed current in memory was 10 amps, Freedom Sequence will wait for a Current To Reconnect of 12 amps calculated as:

Last Load Shed + (20% × Last Load Shed),

to be available before reconnecting the circuit.

By default, the factory setting of Reconnect MGN for all AC relays is set to 10%.

Battery Voltage Triggers

The Freedom Sequence has four DC relays which can be used to connect and disconnect DC loads on the system based on battery voltage thresholds. Each DC relay has a N/O/N/C contact that will toggle (switch between N/O or N/C) if the battery voltage sensed by Freedom Sequence exceeds a Batt High Trig Set voltage or drops below the Batt Low Trig Set voltage. The DC relay will toggle back to the normal position when the battery voltage drops below the Batt High Trig Clear voltage or rises above the Batt Low Trig Clear voltage. Each DC relay can be configured with a unique set of Battery High/Low Trig Set and Battery High/Low Trigger Clear voltages.

By default, each of these voltage triggers is configured to:

Battery Voltage Trigger

Default

Default

 

12-volts

24-volts
