Step; Hz/S; Ramp button:
When Dynamic Enabled is used, the user
selects either Step, Hz/S or Ramp. See section
3.5.5 for detail description of the dynamic
frequency selection for Hz/S. Ramp is very
similar to Hz/S, with the exception that the same
ramp rate is used for both Ramps. The unit
defaults to the Step function, which is the
simplest of dynamic frequency timing tests. The
Step changes from the normal operating
frequency set in the Prefault, and changes to the
fault frequency setting in the Fault setting
screen.
Delta 1 / Delta 2 buttons:
When Dynamic Enabled and Hz/S or Ramp is
selected, these value windows are used to set
changes in output frequency. If a Step function
is used, the Delta 1 and 2 are greyed out and
not used. When Hz/S is selected, both Delta 1
and 2 are accessible. If Ramp is selected only
Delta 1 is programmable.
Timer Setup:
This selection will display the Timer Setup
menu.
Dynamic Enabled / Dynamic Disabled:
The Dynamic Enabled button will simulate four
fault conditions ( Prefault, Fault, and Postfault)
and progress through each state condition. The
Timer will start when the unit progresses from
the Prefault to the Fault condition and will stop
when the first stop contact reaches a true
condition or when the Fault Duration has
elapsed. If the Dynamic Disabled selection is
displayed the system will not progress through
the Prefault, Fault, and Postfault operations.
Start / Stop:
This selection will apply the set quantities
displayed and start the timer or not start the
timer depending upon Timer Start selection. If
the Dynamic Enabled button is selected the unit
will progress through the Pre-Fault; Fault; BKR-
Open and Reclose operations. The Start button
will always reset the timer to zero. After Start is
pressed this button will turn red and display
Stop. Pressing Stop at any time will stop the
test and turn the outputs off.
File:
This selection will take the user to the File
Manager.
Batt Sim Off / Batt Sim On:
This selection will turn the Battery Simulator On
and Off.
Manual Test Menu:
This selection will return the controller to the
Manual Test Menu.
