Setting the Transient Trigger Thresholds in ATPOL II
Press [Setup] key twice. The display will be “Check Trigger Levels?” Press [Yes/Accept]. The present
setting for voltage swell will be displayed. Press [Yes/Accept] twice to advance to the absolute
transient voltage trigger setting.
If you wish to change it, press [No/Reject]. The display will be “Would
you like a suggestion?” If you press [Yes/Accept], it will suggest a trigger 5% above what seems to be
the normal voltage that you are connected to at that time. If you press [No/Reject], it allows you to use
the keypad to enter an RMS value of your choice. Press [Yes/Accept] when you are done.
Following this, the relative transient voltage trigger level is displayed. Press [No/Reject] if you wish to
change it. The display will be “Would you like a suggestion?” If you press [Yes/Accept], it will suggest
a trigger of 10% of the peak of the voltage that you are connected to at that time or 10Vpk, whichever is
higher. If you press [No/Reject], it allows you to use the keypad to enter an instantaneous voltage level
of your choice. Press [Yes/Accept] when you are done.
To skip over checking the swell/dip trigger levels for current, press [Yes/Accept] twice. The present
setting for absolute current transient will be displayed. This value does not apply to neutral current.
.Press [No/Reject] if you wish to change it. The display will be “Would you like a suggestion?” If you
press [Yes/Accept], it will suggest a trigger 50% above what seems to be the peak current level that
you are connected to at that time. If you press [No/Reject], it allows you to use the keypad to enter an
instantaneous current value of your choice. Press [Yes/Accept] when you are done.
Following this, the relative current transient trigger level is displayed. This value applies to whatever
currents have been enabled for triggering. Press [No/Reject] if you wish to change it. Press
[No/Reject] if you wish to change it. The display will be “Would you like a suggestion?” If you press
[Yes/Accept], it will suggest a trigger of 10% of the peak of the current that you are connected to at that
time or 1 Apk, whichever is higher. If you press [No/Reject], it allows you to use the keypad to enter an
instantaneous value of your choice. Press [Yes/Accept] when you are done.
Setting the Transient Trigger Thresholds in PSM
To check or set the transient trigger thresholds, at the main menu click on Data Setup. At the bottom of
the screen is the “Triggering for Swells, Dips, Transients” section. The upper area of this section is for
setting which signals to trigger on and for deciding how many signals to capture when a trigger occurs.
The bottom section is for setting the actual trigger thresholds.
If you wish to trigger on one or
more voltages, check in the
“Voltage to trigger on” section to
make sure that the voltage signals
you wish to trigger on are
checked. Clicking on the box in
front of the signal name results in
a ‘checkmark’ being displayed in the box, indicating that the triggers apply to that signal. Clicking on a
box that already has a checkmark in it, erases the checkmark, indicating that the triggers do not apply t
that signal.
Similarly, if you wish to trigger on one or more currents, check the “Current to trigger on” section and
make sure that the current signals you wish to trigger on are checked.
