Inverse Time, Definite Time and Instantaneous operation is available.		Setting current range: 10 - 1260 A
22.4	Sequence Coordination		Sequence Coordination allows a recloser to coordinate it's trip sequence with another recloser downstream
22.5	Auto-re-closer		Relay 79 (sequence 1,2,3,4)
	Operating Sequence Reclose times are individually selectable. The operating sequence is defined by: O - 1st rt - CO - 2nd rt - CO - 3rd rt - CO where rt = reclose time. where O = open. where C = close.		1st Reclose Time range: 0.2 - 180 sec

22.6	Trips to Lockout		Overcurrent and fault trips to lockout are selectable between 1 and 4. A separate setting is available for Sensitive Earth Fault and Negative Phase Sequence.
22.7	Loss of phase Loss of phase protection trips the re-closer if phase-earth voltage on one or two, phases falls below a set voltage threshold for a set length of time.		Threshold voltage range: 2 - 15kV
			Voltage resolution: 1V

22.8	Live load blocking Live load blocking prevents a re-closer from closing if any of the load side terminals are live.		Live Load Threshold Voltage range: 2 - 15kV
22.9	Dead lockout		Dead lockout prevents a reclose unless one or more of the source side or load side terminals are live. If all terminals are dead, then the controller goes to lockout
22.10	Envelope and low frequency This feature trips the re-closer when the system frequency exceeds the under and over frequency trip threshold values.

22.14	Directional blocking Directional protection		67 relay PGQ/67N a protection feature that restricts tripping on faults to a designated side of the re-closer. It prevents nuisance tripping if network conditions are causing "false" earth faults. In radial systems, Directional Blocking prevents nuisance tripping by blocking faults in the source direction and only responding to faults in the load direction. Distinct protection for faults in the forward and reverse direction. A forward fault may use a different time-current curve and settings to a reverse fault (i.e. these are individually selectable). Both the forward protection and reverse protection are operating at the same time. This is an additional protection feature
