61
When using direct wiring (PT Ratio = 1), voltages are displayed in 0.1 V units, currents
in 0.01 A units, and powers in 0.001 kW/kvar/kVA units. For wiring via PTs (PT Ratio >
1), voltages are displayed in 1V units, currents in 0.01 A units, and powers in 0.001
MW/Mvar/MVA units. When the value width is over the window resolution, the right
most digits are truncated
By default, the maximum range for energy readings is 99,999,999 MWh/Mvarh/MVAh.
Beyond this value, the reading will roll over to zero. When the energy reading exceeds
the window resolution, the right-most digits are truncated. To avoid truncation, you can
change the energy roll value to lower limit via the
User Selectable Options
menu (see
Section 4.9). Negative (exported) energy readings are displayed without a sign.
Per phase power and power factor readings are displayed only in 4LN3/4LL3 and
3LN3/3LL3 wiring modes (see Section 4.1) if the phase powers display is enabled in
the
Display Setup
menu (see Section 4.8).
Phase energy readings are displayed only in 4LN3/4LL3 and 3LN3/3LL3 wiring modes if
they are enabled in the
User Selectable Options
menu (see Section 4.9).
When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for
any other wiring mode, they will be line-to-line voltages.
Displayed only in the 4LN3 or 3LN3 wiring mode.
6.3 Device Diagnostics Display
When the device restarts, either after power up, or as a result of the device
diagnostics test, the C192PF8-RPR display shows for one second the diagnostics
code. Diagnostics codes are listed in Table 5-2. Code ‘8’ indicates normal power
up.
Table 5-2 Self-Test Diagnostics Codes
Code Meaning
2 RAM
error
3
Watch dog timer reset
4 Sampling
failure
5
CPU exception trap
7
Software exception trap
8
Normal power up
9
External reset (warm restart)
The C192PF8-RPR
performs full diagnostics tests after restart and periodically
during operation. The diagnostics results are written to the appropriate bits of the
device self-check diagnostics register accessible through communications (see
the communications reference guides shipped with your instrument). When a
non-critical error is detected, the C192PF8-RPR sets a corresponding fault bit in
the diagnostics register and restart operations showing the last recorded
diagnostics code on the display. Frequent failures may be the result of excessive
electrical noise in the region of the instrument. If the instrument continuously
resets itself, contact your local distributor.
