Source VT Correction
0.0 Volts
VT ratio correction is adjustable from –15 V to +15 V in 0.1 V increments with a factory
setting of 0 V.
Norm. VT. Multiplier
1.00
Normalizing Voltage Multiplier 0.80 to 1.20 times the Compensating Voltage.
Power Display Option
SINGLE_PHASE
Toggles between two modes of operation: Single
‑
Phase – based on measured inputs, and
Three
‑
Phase – based on measured inputs and presumed balanced system. Factory setting
is single-phase.
Regulator Type
TYPE A
Allows the regulator type to be selected as Type A or B for correct source voltage
calculation. Factory setting is Type A.
Output Selection
CONTINUOUS
Allows choice of output at tapchanger Raise/Lower output terminal. Choices are
continuous or pulsed. For continuous, the control must wait to be in band or counter input
valid for output to become disabled. For pulsed, an adjustable pulse width will be applied
to the output triacs of 0.2 to 12 seconds.
Output Pulse
1.5 Sec
Adjustable from 0.2 to 12 seconds in 0.1 second increments. Factory set at 1.5 seconds.
