Introduction 3
Setpoints
• 16 programmable setpoints for monitoring various events:
- up to 4 triggering conditions for each setpoint combined by OR/AND
logical operations
- up to 4 actions for each setpoint on setpoint operation
- programmable hysteresis (dead-band) for analog triggers
- programmable delay for setpoint operation/release
• each setpoint can be combined with other setpoints if extended number of
conditions or actions needed
• any measured or sensed quantity/status/pulse/event can be used as a trigger
condition for setpoint operation
• voltage disturbance and phase rotation monitoring are available for triggering
setpoint operations
• setpoint actions available:
- operating relay output
- increment/decrement/clear counter
- assert/clear user programmable event
- reset total accumulating energy registers
- reset extreme demand registers
- reset TOU system accumulating energy registers
- reset TOU system demand registers
- clear all counters
- clear Min/Max log registers
- event logging on setpoint operation
- data logging in selected data log partition
- high-speed waveform logging for disturbance analysis
- high-resolution waveform logging for harmonic analysis
• each setpoint can be programmed to be operated manually via
communications by overriding present conditions or by gating setpoint
operations in addition to other setpoint conditions (for example when
event/data recording is needed for a user-defined time interval)
• each setpoint can be programmed to allow the setpoint operations to be
recorded in the event log on any setpoint transition - operate, release or either
transition
On-board Data Recording
• 19 free-programmable extended memory partitions for recording events,
measured data, and captured waveforms:
- one event logging partition for recording various events and setpoint
operations, providing storage for up to 36864 events with a 512K
memory module (assuming the entire memory allocated for the
partition)
