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.
