Soft Arc Detection
Press the PROMPT key and then the
key until the “Soft Arc Detection” Prompt Screen
appears.
Due to low signal to noise ratios, poor electrical grounding, heavy electrical noise, etc. it
may be necessary to detect arcs (soft arcs) from secondary electrical values in place of
primary electrical values. The following two screens show how this is accomplished.
To detect a soft arc, both the secondary voltage (Vs) value and the secondary current
value (Is) must be detected simultaneously.
Press ENTER and the ‘Soft Arc Vs Delta” Parameter Screen will appear.
This screen allows the setting of the secondary voltage (Vs) drop (delta) value for the soft
arc detection. The secondary voltage value can be anywhere in the range shown, in one
KV increments.
If the operating value is to be changed, simply press the numeric key(s) corresponding to
the new value desired (the old value will be overwritten), and press ENTER. If the
present operating value is acceptable, simply press ENTER without making any changes.
The “Soft Arc Is Delta” screen will now appear.
This screen allows the setting of the secondary current (Vs) increase (delta) value for the
soft arc detection. The secondary current value can be anywhere in the range shown, in
one ma increments.
If the operating value is to be changed, simply press the numeric key(s) corresponding to
the new value desired (the old value will be overwritten), and press ENTER. If the
present operating value is acceptable, simply press ENTER without making any changes.
Press the
or
keys to view more prompt screens or press ESC to return the display to
either the Electrical Reading Screen or the Device Status Screen depending on the
screen you were in prior to pressing the PROMPT key.
Switching to Manual Operation
The control can be placed in the Manual operating mode by placing the Auto-Manual
toggle switch, on the Interface Unit, in to the Manual position (see page 58).
Once the Auto-Manual switch
is placed in Manual mode, the words “Manual Mode” will
appear on the Status Line in the Device Status Display.
