ConF Wiring mode
2LL1 3-wire/4-wire connection using the current
from one phase (1 CT) and the L-L voltage
from the two other phases
Pt PT ratio 1.0*-6,500.0 The phase potential transformer ratio
Ct CT primary current 1-6,500A
(5 ∗ )
The primary rating of the phase current
transformer
d.P Power demand
period 1, 2, 5, 10,
15*, 20, 30,
60, E The length of the demand period for power
demand calculations, in minutes. E = external
synchronization
n.dp Number of power
demand periods 1-15
(1*) The number of demand periods to be averaged
for sliding window demands
1 = block interval demand calculation
A.dP Ampere/Volt
demand period 0-1800 s
(900*) The length of the demand period for
volt/ampere demand calculations
0 = measuring peak current
buF Averaging buffer
size
8 ∗ ,16,32 The number of measurements for RMS sliding
averaging
rSt Reset
enable/disable
diS ∗ , En Protects all reset functions, both via the front
panel or communications.
Freq Nominal frequency 50, 60 Hz The nominal power utility frequency
LoAd Maximum demand
load current 0-6,500A
(0
∗ )
The maximum demand load current used in
TDD calculations (0 = CT primary current)
When the power demand period is specified in minutes, synchronization of the demand
interval can be made through communications (see the C192PF8-RPR Modbus
Reference Guides) or via the front panel (see Section 4.11). If the power demand period
is set to External Synchronization, an external synchronization pulse denoting the start
of the next demand interval can be provided through a digital input or can be simulated
by using the synchronization command sent via communications.
60 Hz default for North America; elsewhere, default is 50Hz.
