The setpoint is used to adjust the mains voltage transformers ratio.
NOTE:
Adjust the setpoint to the value of 1.00 if the mains voltage is connected
directly to the controller terminals, i.e. without transformers.
NOTE:
Example: if you have transformers with ratio 6000/100V adjust the setpoint to
the value of 60.00.
NOTE:
The range of the mains voltage inputs must be adjusted properly. See the
setpoint Vm InpRangeSel.
11.2.2.2 Setpoint: Vm InpRangeSel
This setpoint selects the range of the mains voltage terminals. The 120V
range is available only in IM-NTC hardware. The IM-NT has the range
adjusted fixedly to 277V regardless of this setpoint.
NOTE:
The 277V range is suitable for both European (230V) and American (277V)
measurement. The range 120V is intended for high-voltage applications
where voltage transformers with 100V secondary range are used or for
alternative American (120V) measurement.
11.2.2.3 Setpoint: Bus VT ratio
The setpoint is used to adjust the bus voltage transformers ratio.
NOTE:
Adjust the setpoint to the value of 1.00 if the bus voltage is connected directly
to the controller terminals, i.e. without transformers.
