Description The setpoint is used to adjust the mains voltage transformers ratio.
N
OTE
:
Adjust the setpoint to the value of 1.00 if the mains voltage is connected
directly to the controller terminals, i.e. without transformers.
N
OTE
:
Example: if you have transformers with ratio 6000/100V adjust the setpoint to
the value of
60.00 .
N
OTE
:
The range of the mains voltage inputs must be adjusted properly. See the
setpoint
Vm InpRangeSel .
11.2.2.2 Setpoint: Vm InpRangeSel
Group Basic settings
Range [units] 277V, 120V [-]
Related FW standard v3.1.0
Description 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.
N
OTE
:
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
Group Basic Settings
Range [units] 0.10 .. 500.00 [V/V]
Related FW standard v3.1.0
Description The setpoint is used to adjust the bus voltage transformers ratio.
N
OTE
:
Adjust the setpoint to the value of 1.00 if the bus voltage is connected directly
to the controller terminals, i.e. without transformers.
