		If the test register value exceeds the setpoint long enough to satisfy the pickup
010	Over Value Alarm	delay period, the alarm condition will be true. When the value in the test register
		falls below the dropout setpoint long enough to satisfy the dropout delay period,
		the alarm will drop out. Pickup and dropout setpoints are positive, delays are in
		seconds.
		If the absolute value in the test register exceeds the setpoint long enough to
		satisfy the pickup delay period, the alarm condition will be true. When absolute the
011	Over Power Alarm	value in the test register falls below the dropout setpoint long enough to satisfy the
		dropout delay period, the alarm will drop out. Pickup and dropout setpoints are
		positive, delays are in seconds.
		If the absolute value in the test register exceeds the setpoint long enough to
	Over Reverse	satisfy the pickup delay period, the alarm condition will be true. When absolute the
012		value in the test register falls below the dropout setpoint long enough to satisfy the
	Power Alarm	dropout delay period, the alarm will drop out. This alarm will only hold true for
		reverse power conditions. Positive power values will not cause the alarm to occur.
		Pickup and dropout setpoints are positive, delays are in seconds.
		If the test register value is below the setpoint long enough to satisfy the pickup
020	Under Value Alarm	delay period, the alarm condition will be true. When the value in the test register
		rises above the dropout setpoint long enough to satisfy the dropout delay period,
		the alarm will drop out. Pickup and dropout setpoints are positive, delays are in
		seconds.
		If the absolute value in the test register is below the setpoint long enough to
021	Under Power Alarm	satisfy the pickup delay period, the alarm condition will be true. When the absolute
		value in the test register rises above the dropout setpoint long enough to satisfy
		the dropout delay period, the alarm will drop out. Pickup and dropout setpoints are
		positive, delays are in seconds.
		The phase reversal alarm will occur whenever the phase voltage waveform
051	Phase Reversal	rotation differs from the default phase rotation. The ABC phase rotation is
		assumed to be normal. If a CBA phase rotation is normal, the user should
		reprogram the power meter’s phase rotation ABC to CBA phase rotation. The
		pickup and dropout setpoints for phase reversal do not apply.
		The phase loss voltage alarm will occur when any one or two phase voltages (but
		not all) fall to the pickup value and remain at or below the pickup value long
052	Phase Loss, Voltage	enough to satisfy the specified pickup delay. When all of the phases remain at or
		above the dropout value for the dropout delay period, or when all of the phases
		drop below the specified phase loss pickup value, the alarm will drop out. Pickup
		and dropout setpoints are positive, delays are in seconds.
		The phase loss current alarm will occur when any one or two phase currents (but
		not all) fall to the pickup value and remain at or below the pickup value long
053	Phase Loss, Current	enough to satisfy the specified pickup delay. When all of the phases remain at or
		above the dropout value for the dropout delay period, or when all of the phases
		drop below the specified phase loss pickup value, the alarm will drop out. Pickup
		and dropout setpoints are positive, delays are in seconds.
		The leading power factor alarm will occur when the test register value becomes
		more leading than the pickup setpoint (such as closer to 0.010) and remains more
		leading long enough to satisfy the pickup delay period. When the value becomes
		equal to or less leading than the dropout setpoint, that is 1.000, and remains less
054	Leading Power Factor	leading for the dropout delay period, the alarm will drop out. Both the pickup
		setpoint and the dropout setpoint must be positive values representing leading
		power factor. Enter setpoints as integer values representing power factor in
		thousandths. For example, to define a dropout setpoint of 0.5, enter 500. Delays
		are in seconds.
		The lagging power factor alarm will occur when the test register value becomes
		more lagging than the pickup setpoint (such as closer to –0.010) and remains
		more lagging long enough to satisfy the pickup delay period. When the value
055	Lagging Power Factor	becomes equal to or less lagging than the dropout setpoint and remains less
		lagging for the dropout delay period, the alarm will drop out. Both the pickup
		setpoint and the dropout setpoint must be positive values representing lagging
		power factor. Enter setpoints as integer values representing power factor in
		thousandths. For example, to define a dropout setpoint of –0.5, enter 500. Delays
		are in seconds.
Digital
		The digital input transition alarms will occur whenever the digital input changes
060	Digital Input On	from off to on. The alarm will dropout when the digital input changes back to on
		from off. The pickup and dropout setpoints and delays do not apply.
		The digital input transition alarms will occur whenever the digital input changes
061	Digital Input Off	from on to off.The alarm will dropout when the digital input changes back to off
		from on. The pickup and dropout setpoints and delays do not apply.
		This is a internal signal from the power meter and can be used, for example, to
070	Unary	alarm at the end of an interval or when the power meter is reset. Neither the
		pickup and dropout delays nor the setpoints apply.
