N7:43 Control
Word
(1)
This is the control word for the capacitor bank
controller. The first three (3) bits of the control
word is used to set the CTPT Mode. Bit 4 is used
to initiate a restore of factory defaults. This
should be treated as a momentary state. Bit 5 is
used to initiate the step size buffer. This bit should
also be treated as a momentary state. Bit 6 is
used for disabling step tolerance. The BCD value
for each bit is available for easy setup.
Examples
- CTPT Mode 2 and Disable Step Tolerance = 68
- CTPT Mode 0 and Restore Factory Defaults = 17
to initiate a restore, then 1.
- CTPT Mode 1 and Initiate Step Buffer = 34 to
initiate step buffer, then 2
