6.4.2 Intertap time delay
The intertap time delay may be used in conjunction with sequential operation or pulsed
output. The normal operation of this delay timer occurs once a tapchange command is
initiated, when there would normally be a continuous command (raise or lower) to run the
tapchanger until the voltage has returned to within the band setting, there is now an
intertap time delay initiated between tapchanges. When the intertap time delay is set to
zero, it is disabled.
The intertap time delay will:
• Recognize that a tapchange has occurred, indicated by the counter contact input or
motor hold input.
• Remove the output signal and wait for the intertap time delay, even though the voltage
remains outside the designated voltage band.
• Command another tapchange after the intertap time delay has expired, without regard
to the basic time delay setting, if the voltage remains out of band in the same direction
as the previous tapchange.
If the intertap time delay is enabled on a control where non-sequential operation is
enabled, the intertap time delay setpoint is disregarded. The basic time delay setting
prevails for subsequent tapchange commands in the non-sequential mode.
The intertap time delay is similar in operation to non-sequential operation,
but the two should not be confused. The intertap time delay applies a short
delay after every tapchange. The non
‑
sequential operation time delay will
be the same as that of the Basic User
‑
Selected Time Delay. Application
with pulsed output is also possible.
