Sequential/Non-Sequential/Blocking
The control normally operates in Sequential Mode. In this mode, the tapchange output is
initiated after the time delay timer has timed out. The tapchange output will remain "on"
until the control senses that the voltage has returned in-band. This permits successive
tapchanges to be made in a "sequential" mode with no delay between tapchanges.
If a delay between successive tapchanges is desired, an intertap time delay may be used.
The value is set from 0 to 60 seconds and will interrupt tapchange outputs for the preset
time after a counter-contact closure or motor hold input is detected by the control's
operations counter input #1.
If the full initial time delay is desired, the control may be used in the "non-sequential"
mode. Enabling non-sequential mode operation is accomplished by setting the Input
Selection 2 setting to "non-sequential". Applying a momentary contact closure to the
control's Input Selection 2 will activate non-sequential mode operation.
If the closed contact supplied to Input Selection 2 is maintained, instead of momentary, the
initial timer will not time out for the duration of the maintained contact, and the outputs
of the control will be effectively blocked.

Tapchanger Type
3.
Press the Right or Left arrow pushbutton, as necessary, to navigate to the "Tap
Settings" menu.
4.
Press the Down arrow pushbutton, as necessary, to navigate to the "Intertap Delay"
menu item.
5.
Press the ENT pushbutton. If prompted, enter a valid Level 2 Access Code. The
following will be displayed:
Intertap Delay
0 Sec C
6.
Utilizing the arrow pushbuttons enter the desired Intertap Time Delay value (0 to 60
seconds in 1 second increments), then press the ENT pushbutton.
