Output pulse
If an appropriate pulse width setting is not entered, then a misoperation of
the tapchanger may occur when a SCADA Manual Raise or Lower is
initiated.
When the output selection is "Pulsed", the pulse width can be programmed from 0.2 to 12
seconds, in increments of 0.1 seconds. An initiated pulse will continue until the pulse time
has been reached or a counter contact or motor hold input operates.
Under normal conditions, when the output is set to "Pulsed" and the control is calling for
Raise/Lower, an output will turn on for the pre
‑
programmed time, or until a counter
contact or motor hold input operates, and then turn off the output for a time period of 0.5
seconds plus the intertap time delay setting value. When the control is calling for a Raise/
Lower and no non
‑
sequential or counter input or motor hold input is applied, the output
will activate for the full pre
‑
programmed time and deactivate for 0.5 seconds, plus the
intertap time delay.
When a counter input or motor hold input is applied, and there is an intertap delay, the
pulse will cease immediately with counter contact closure for the intertap time delay.
After the counter contact or motor hold input opens, the intertap timer will start at the end
of the time delay. If there is still a Raise/Lower condition, another pulse will start.
When the non
‑
sequential input is applied, the Raise/Lower timers will reset with the
contact closure, and a timer count will start again, if a Raise/Lower condition is still
present, the pulse will start once more.
SCADA INITIATED Manual Raise/Lower
When the control is placed in Manual via SCADA, to perform a Manual Raise/Lower, the
control will switch to the "Pulsed" output mode until the control is returned to "Auto". This
