Digitrip 1150 Settings (continued)
Setting
Description
Long Memory
(Thermal Memory)
Indicates whether over-current memory function is on or off. (Applicable on LSI,
LSIG and LSIA curves only.)
Sliding Window Assignment
Determines if the maximum kW demand or the maximum kVA demand is
calculated on a fixed or sliding 15-minute window.
Auto Waveform Capture Interval
The time between auto waveform captures.
High INST Trip
The circuit breaker tripped at a high fault current via separate High INST Module.
See Appendix C.
High Load Alarm
When the current reaches the setting, a High Load Alarm occurs.
High Load Time
The circuit breaker waits the duration of the High Load Time before entering into
an alarm condition.
Alarm to Event Log
When enabled, alarm events are stored into the Event Log.
Ground Pickup Alarm
When ground current exceeds this setting, a Ground Pickup Alarm occurs (when
applicable).
Neutral Pickup Alarm
When neutral current exceeds this setting, a Neutral Pickup Alarm occurs.
Breaker Operations Count Alarm
When circuit breaker operations count exceeds this setting, a circuit Breaker
Operations Count Alarm occurs.
Low Power Factor Alarm
When the power factor falls below this setting, a Low Power Factor Alarm occurs.
THD Alarm
When the percent THD exceeds this setting, a THD Alarm occurs.
kW Demand Alarm
When the kW demand reaches this setting, a kW Demand Alarm occurs.
kVA Demand Alarm
When the kVA demand reaches this setting, a kVA Demand Alarm occurs.
