supplyVoltage SNVT_volts

Measured supply voltage 0.1V resolution. This
value is updated every second.

supplyCurrent unsigned

long

Measured current with 0.01 amp resolution. This
value is updated every second.

cycleCount SNVT_count

Number of operating cycles (ON-OFF). Updated
with each transition to OFF.

LevelFB SNVT_lev_cont

0.5% resolution 0-100%. Tracks the .value field of
nvoLampFb

. 0% if the state is 0.

faults UNVTfaults

Fault bits. Details are provided in the alarms
section. These bits represent current conditions of

the last alarm evaluation and not the latched values
as reflected in nvoLcStatus.

nvUpdates Unsigned

Used to assess application level communication
performance. Every 30 minutes, this field is

updated to report the number of times
nviLampValue

was updated in the previous

interval. If the defined heartbeat for
nviLampValue

is defined as 10 minutes, this value

reports a value of 2-4 during steady state operation.

rcvTimeouts SNVT_count

The maximum receive timeout for this device (part
of nciControlCfg) is set to three times the control
input heartbeat. In practice, this number increases
only when an update is not received after three

heartbeat intervals.

powerFactor SNVT_pwr_factor

Reports the measured power factor for the
LC/Fixture combination. When the controlled load

is OFF, this value will be very low (around .3).

Alarms against power factor are only evaluated
when the load is turned ON. For efficient light

operation, it is good practice to limit the control

signal the CPD 3000 drives to keep the power factor
above 0.8.

LCtemperature SNVT_temp_p

Reports the temperature sensed by the power

measurement chip on the CPD 3000. Typical
accuracy is +/-5 degrees C.

LCstate OLC_State

Reports the current state of the CPD 3000 LC
controller. Valid values include: OLC_INIT,
OLC_COOLDOWN

, OLC_WARMUP, OLC_ON, and

OLC_OFF

.
