•
Flip Current for Strip 2: Check this box to reverse the 3-phase current measurements on strip 2
from ABC to CBA.
•
Temperature in Fahrenheit: measurements and alarm thresholds will be given in Fahrenheit,
rather than in the default Celsius.
•
Current loss: Check this box to enable the Current Loss Alarm. When an active circuit (defined as
a circuit that has measured over 1.5A) goes to a 0A measurement, an alarm for Current Loss is
raised.
Other settings:
•
Demand Time: Demand is the current (amperage) measurement, averaged over a time period. Set
the number of minutes over which demand is averaged.
•
Thermal OT: Do not set this value, which is the over-temperature alarm threshold for the iBus
PCB. Use the default value of 80
⁰
C.
•
Thermal UT: Do not set this value for under-temperature alarm for the iBus PCB.

Data Tab
While the IBus Tab sets uniform global values for all Tap Off Boxes in the bus run, the Data Tab lets you
set values in the points list of each device individually (Figure 13).
Each device, both the single Input Power Monitor (Input PM) PCB and all IBUS (Tap Off Box) PCBs, has its
own points list, which can be displayed and modified in the
Data Tab
. The
Data Tab
lets you display and
change data for each point or Modbus register in a specific points list.
How to change a point or Modbus register:
1.
Click the
Data Tab
to access the points list (Modbus register map) for a specific device. The
screen will show the selected device and its points list. The device is identified by device type
(either the input power source at the power feed (
INP PM
) or a Tap Off Box (
IBus
), device
unique identifier, and its Modbus address.
2.
Select a device
. Click the top drop-down box to select a device by its Modbus address.
3.
The points list for this Modbus address will be shown in the large points-list window. Modbus
registers (points) are listed in sequential order with point name and current value of the point.
4.
Device with address 1 is usually the
Input Power Monitor (INP PM)
. The remaining devices are
Tap Off Box devices, shown as
IBUS
, the PCB containing the Tap Off Box points list.
5.
The currently selected register in the points list is also shown in the
Write to Modbus
box.
6.
Select a point.
Scroll through the device’s points list. Click to h
ighlight a point to display and/or
modify. The point is displayed in
Write to Modbus
.
7.
Modify the point data
.
8.
You may wish to change several points. When satisfied with modifications,
save changes
to
EPROM by clicking
Save Memory
.
