alarm is triggered.
(Defaults value - 65.0 C)
nciLimits.lampFailFault SNVT_lev_cont
The threshold of power
drop measured when the
lamp fails. In some
technologies, induction
lights for example, the
power draw at bulb failure
may be quite high.
(Default value - 20%).
The field nciControlCfg.clrTm controls when the alarm flags reported in
nvoLcStatus will be cleared. In an SLV managed lighting system, alarm logs are
scheduled for daily delivery at some point after the sunrise OFF command. For
example, this could be scheduled for 10:00AM. Over the year, sunrise time varies
with the season and the geographic location. For example, it could occur between
5:15 and 7:45 AM. To support proper management of alarms, alarms should not
be cleared until at least five hours or more after sunrise.
nciControlCfg.clrTm
should be set to 300 minutes to support clearing of the
alarms after the logs have been delivered.
Figure 6. Fault Limits
During characterization of a driver/lamp combination, it may be useful to use
nviStatReset.cmd
, a value of SM_CLEAR_ALARMS. The following table lists the
fault bits reported by nvoControlData.faults and nvoLCstatus.

LowPower Measured power is nciLimits.powerLowFault % below the
expected power
HighPower Measured power is nciLimits.powerHighFault % above the
expected power
