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

Setpoint: Vm InpRangeSel
Group
Basic settings
Range [units]
277V, 120V [-]

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.

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.
