Temp Alarm
Max
Threshold
D1 0.1°C +70°C
Maximum Temperature Alarm
Threshold. A temperature above
this threshold will set the alarm
(bit 1 of the Alarm Status
Register).
If the maximum
temperature threshold is to
be change to 50°C then set
as follows:
>)D1=+50.0
Frequency
Minimum
Threshold
D2 0.01Hz +59.00
Minimum Frequency Alarm
Threshold. A frequency below
this threshold will set the alarm
(bit 2 of the Alarm Status
Register).
If the minimum frequency
threshold is to be changed
to 59.50 Hz then enter the
following:
>)D2=+59.50
Frequency
Maximum
Threshold
D3 0.01Hz +61.00
Maximum Frequency Alarm
Threshold. A frequency above
this threshold will set the alarm
(bit 3 of the Alarm Status
Register).
If the maximum frequency
threshold is to be changed
to 60.50 Hz then enter the
following:
>)D2=+60.50
SAG Voltage
Alarm
Threshold
D4 mVpk +80.0
Sets an alarm (bit 4 of the Alarm
Status Register) if voltage drops
below the SAG threshold.
Min Voltage
Alarm
Threshold
D5 mVrms +100.000
Minimum voltage level selected to
flag user (bit 5 of the Alarm Status
Register).
To change the minimum
voltage threshold from the
40 Volt default to 80 Volts:
)D5=+80.000
Peak Voltage
Alarm
Threshold
D6 mVrms +140.000
Peak voltage setting that user
wishes to flag (bit 6 of the Alarm
Status Register).
To change the peak voltage
threshold from the default
407.3 Volts to 280 Volts:
)D6=+280.000
Unused D7 –
Peak IA_nb
Alarm
Threshold
D8 mArms +15.000
Maximum Narrowband Current
measured on the IA channel
above which a flag must set (bit 7
of the Alarm Status Register).
If the peak narrowband
current threshold on Outlet
1 is to be changed from the
default value of 15 Amps to
30 Amps then set as
follows:
)D8=+30.000
Peak IA_wb
Alarm
Threshold
D9 mArms +15.000
Maximum Wideband Current
measured on the IA channel
above which a flag must set (bit 8
of the Alarm Status Register).
If the peak wideband
current threshold on Outlet
1 is to be changed from the
default value of 15 Amps to
30 Amps then set as
follows:
)D9=+30.000
PFA_nb_Neg
Threshold
DA – -0.700
Narrowband Power Factor
Negative Threshold for Outlet 1.
A less negative narrowband
power factor than this threshold
will set an alarm (bit 9 of the
Alarm Status Register). Only
available if )F2 bit 2 is set to 1.
If the negative narrowband
power factor threshold on
Outlet 1 is to be changed
from the default to -0.6 then
set as follows:
)DA=-0.600
