SA-DI Command
Purpose:
Read or set current demand alarm thresholds.
Syntax:
SA-DI<x>[=<Alarm Level>]
Comments: x = P (Phase), N (Neutral), or Q (Negative Sequence). See Table 6-5 for SA-DI Settings
Information.
SA-DI Command Example
1.
Set the demand alarm thresholds at six amperes for A, B, and C Phase current and three amperes for
Neutral and negative sequence current.
>SA-DIP=6.0; SA-DIN=3.0; SA-DIQ=3.0
Demand alarm thresholds for three-phase power and reactive power are set using the SA-DWATT and
SA-DVAR commands. Demand alarm settings for power are summarized in.
SA-DVAR/DWATT Command
Purpose:
Read or set reactive power or power demand alarm thresholds.
Syntax:
SA-DVAR/DWATT[=<Fwd alm lvl>,<Rev alm lvl>]
Comments: All values read or entered are in secondary units. See Table 6-5 for SA-DAR/WATT settings
information.
SA-DVAR/DWATT Command Examples
1.
Read the reactive power demand alarm thresholds.
SA-DVAR
2000,50
2.
Set the forward power demand alarm threshold at 3000 watts and the reverse power demand alarm
threshold at 100 watts.
SA-DWATT=3000,100
BREAKER MONITORING
Breaker monitoring helps manage equipment inspection and maintenance expenses by providing extensive
monitoring and alarms for the circuit breaker. Breaker monitoring functions include breaker status and
operations counter reporting, fault current interruption duty monitoring, and trip-speed monitoring. Each
function can be set up as a programmable alarm. The Alarm Functions subsection has more information
about the use of programmable alarms. The breaker trip circuit voltage and continuity monitor is a related
function and is described in the Trip Circuit Monitor subsection.
Breaker Status Reporting
The breaker status monitoring function monitors the position of the breaker for reporting purposes. Opening
breaker strokes are also counted and recorded in the breaker operations counter register. Circuit breaker
status is also used by the breaker trip circuit voltage and continuity monitor. The Trip Circuit Monitor
subsection provides more details.
