If the test register value exceeds the setpoint long enough to satisfy the pickup delay period, the

010

 

 

Over Value Alarm

 

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 dropout. 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

Over Power Alarm

 

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 dropout. 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 the value in the test register falls below the dropout

012

 

 

Over Reverse Power Alarm

 

setpoint long enough to satisfy the dropout delay period, the alarm will dropout. 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 delay period, the

020

 

 

Under Value Alarm

 

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 dropout. 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 satisfy the pickup delay

Under Power Alarm

 

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 dropout. Pickup and dropout

 

 

 

 

 

 

 

 

 

 

setpoints are positive, delays are in seconds.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The phase reversal alarm will occur whenever the phase voltage waveform rotation differs from the

051

 

 

Phase Reversal

 

default phase rotation. The ABC phase rotation is assumed to be normal. If a CBA phase rotation

 

 

 

is normal, the user should reprogram the circuit monitor’s phase rotation ABC to CBA phase

 

 

 

 

 

 

 

 

 

 

rotation. The pickup and dropout setpoints and delays 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 enough to satisfy the specified pickup

052

 

 

Phase Loss, Voltage

 

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 dropout.

 

 

 

 

 

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 enough to satisfy the specified pickup

053

 

 

Phase Loss, Current

 

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 dropout.

 

 

 

 

 

Pickup and dropout setpoints are positive, delays are in seconds.
