6.9 Energy Pulse Width
Note: Energy Pulse Width ( PulseWidth ) only applies to
E1, E2, or E3 pins that are configured to output pulses.
When any are configured to output steady-state signals,
Table 5. E3 Pin Configuration
When both E2MODE bits are high, the E1MODE bits
are enabled, allowing active, apparent, reactive, or wide
band reactive energy for both energy channels to be
output on E1 and E2. Table 6 lists the functions of E1
and E2 with E1MODE enabled.
such as voltage1 sign, power fail monitor, or energy
sign, pulse widths and output rates do not apply.
The pulse width time (t pw ) in Figure 2 , is set by the value
in the PulseWidth register which is an integer multiple of
the sample or output word rate (OWR). At OWR of
4000 Hz (a period of 250 uS) t pw = PulseWidth x
250 uS. By default, PulseWidth is set to 1.

The full-scale pulse frequency of enabled E1, E2, E3
pins is the value in PulseRate x output word rate
(OWR)/2. The actual pulse frequency is the full-scale
pulse frequency multiplied by the pulse register’s
( E PULSE , S PULSE , or Q PULSE ) value.
Example:
Table 6. E1 / E2 Modes
When E1MODE bits are enabled, the E3 pin outputs ei-
ther th e power fail monitor status, or the sign of the E1
and E2 outputs. Table 7 list the functions of the E3 pin
using E3MODE[1:0] in the Modes register when
E1MODE is enabled .
If the output word rate (OWR) is 4000 Hz, and the
PulseRate register is set to 0.05, the full-rate pulse fre-
quency is 0.05 x 4000 / 2 = 100 Hz. If the E PULSE regis-
ter, driving E1, is 0.4567, the pulse output rate on E1 will
be 100 Hz x 0.4567 = 45.67 Hz.
6.11 Voltage Sag/Current Fault Detection

aged voltage falls below a predetermined level for a

specified interval of time. Current fault detection deter-
mines when averaged current falls below a predeter-
mined level for a specified interval of time.
The specified interval of time (duration) is set by the val-
ue in the V1Sag DUR ( V2Sag DUR ) and I1Fault DUR
( I2Fault DUR ) registers. Setting any of these to zero (de-
fault) disables the detect feature for the given channel.
Table 7. E3 Pin with E1MODE enabled
The value is in output word rate (OWR) samples. The
predetermined level is set by the values in the
V1Sag LEVEL
( V2Sag LEVEL ) and
I1Fault LEVEL
( I2Fault LEVEL ) registers.
