6.2 Operating The PowerLoop Calculator Tool
6.2.1 Loop driver type
Select first the PowerLoopDriver type (BSD-340 or BSD-340Ex)
6.2.2 Add Button
• Enter the cable length and cable dimension (the dimension is for
your information only).
• Enter the specified resistive loss of the cable to be used.
• Select the detector type X33/1, BN-342 or Junction Box.
• If BN-342/EX is selected, also enter the actual load to the external
equipment/detector (supplied by BN-342/EX).
Note that if illegal float values are typed or the float value is zero, a
fault warning will popup.
• Press the Add button and a new row will be added to the list box
above.
The calculation is for break after last loop unit. Each row in the table
shows the cable segment and the following detector. To close the
loop (last detector to loop drive), the “End of cable back to BSD-340”
field is used.
or
The tool calculates the current flow and voltage drop per segment into
the table. Regressive calculation is used to approximate a result
displayed in the list box.
