PFB_wb_Neg
Threshold
E2 – -0.700
Wideband Power Factor Negative
Threshold for Outlet 2. A less
negative wideband power factor
than this threshold will set an
alarm (bit 17 of the Alarm Status
Register). Only available if )F2 bit
2 is set to 1.
If the negative wideband
power factor threshold on
Outlet 2 is to be changed
from the default to -0.6 then
set as follows:
)E2=-0.600<CR>
PFB_wb_Pos
Threshold
E3 – +0.700
Wideband Power Factor Positive
Threshold for Outlet 2. A positive
wideband power factor less than
this threshold will set an alarm (bit
18 of the Alarm Status Register).
If the positive wideband
power factor threshold on
Outlet 2 is to be changed
from the default to +0.6
then set as follows:
)E3=+0.600<CR>

(bit 19 of the Alarm Status
Register).
If the narrowband peak
current threshold on Outlet

changed from the default
value of 20 Amps to 30
