Freq:
Controls the Frequency of any installed voltage
(V1, V2, V3, V4) or current (I1, I2, I3, I4)
generator.
Timer Start on Frequency:
Timer Start Contact selection will start the timer
when the first start contact results in a true
condition and the timer will stop and the
generators will turn off when the first stop
contact results in a true condition. The Timer
Start Auto selection will start the timer when the
Start button is pressed and the timer will stop
and the generators will turn off when the first
stop contact results in a true condition.
No. of Repetitions:
This feature allows the ramping of the output
frequency, using the Hz/Sec ramping function,
either down / up or up / down, a fixed number of
times. This is a powerful tool when testing
outputs from frequency stabilizers, which require
repetitive frequency ramping. The default setting
is 1.
Op. Time:
The Op. (operating / trip) time will display the
time from initiation of the timer to the time when
the first stop post results in a true condition.
Duration:
A Duration time can be selected for each
Prefault, Fault, and Postfault state. If the
Duration time is set for zero the unit will skip that
state.
The Prefault button:
With Dynamic Disabled, the user simply uses
the selected test sources as a steady-state
tester. When Dynamic Enabled is used, the user
enters the values for voltage, phase angle and
frequency, with the Duration time. These values
will be applied to the device under test during
the Prefault Duration time, and will then switch
to the Fault Settings.
The Fault button:
When Dynamic Enabled is used, the user enters
the Fault values of voltage, phase angle and
frequency, with a Duration time. These values
will be applied to the device under test during
the Fault Duration time, or until the device trips
(which ever comes first)
and will then
switch to the Postfault Settings.
The Postfault button:
When Dynamic Enabled is used, the user enters
the values for voltage, phase angle and
frequency, with the Duration time. These values
will be applied to the device under test during
the Postfault Duration time, and will then switch
outputs off.
