X2
Operation count will increment by one with either an open-close or a close-open state
change of the tapchanger operation counter switch. Both the closed and open states may
exist indefinitely.
X Mode Delay (X2)
When the control is in X2 Mode detection, the X Mode Delay setting is used to delay the
detection and processing of the next X2 counter contact signal. This is necessary
especially in the case where the neutral signal starts before the next counter contact signal
when the voltage regulator is moving to neutral.
Count Window
Operation count will increment by only one count during a set time period of "Count
Window". This is true no matter how many counter inputs occur during the count window
time. After a counter input is accepted, the count window timer begins and another count
won't be accepted until the count window time expires. The count window time can be set
from 0.5 to 60.5 seconds.
The Count Window setting should not be set to a value greater than the
Intertap Delay when in pulsed or continuous mode. Also, it should not be
set greater than the Pulse Width setting, if Pulsed mode is used.
Cam Follower
The Cam Follower setting should be selected when a Cam Follower contact input is wired
into the Counter contact input of the TCC300. The operation counter and resettable
operation counter will increment when the counter input sees the cam follower open and
then close.
The Cam Follower contact requires a minimum of 500 milliseconds to
open and a minimum of 500 milliseconds to close. For this reason, if
configuring the Output Selection to Pulsed Mode, the Pulse Width must
be set to longer than the actual time it takes for the Cam Follower switch
to complete its operational cycle. If this is not set correctly, tap position
could be inaccurate. ABB recommends that Output Selection be
configured to Continuous unless the LTC mechanism requires Pulsed
Mode to operate correctly.
Cooper Quick Drive
The Cooper Quick Drive setting should be enabled for a Cooper QD regulator. When
enabled, this setting applies a 0 second seal-in output. For Cooper Spring Drive and Direct
