4.6.1.1 AC Voltage Select
The controller has the ability to automatically change its AC sensing (voltage and current) and display configuration through the
use of switched inputs. When using voltage select, the controller will continue to monitor the inputs for 10 seconds after crank
success. Once that time expires, the controller will then display the selected voltage configuration.
The following must be set:
1. Two switched inputs (Switched I/O > Switched IN X > Function ) must be set to the Volt Select 1 and Volt Select 2
switch input functions.
2. AC Monitor > Genset Voltage > Voltage Source must be set to Auto Selection . Rapid Configuration Software note: this
option will not appear unless step one if performed.
The table below shows the relation between the switched inputs status and the voltage configuration.
Volt Select 1 Input Volt Select 2 Input Voltage Configuration
Inactive Inactive 3-Wire Single Phase
Active Inactive 3-Phase (1)
Inactive Active 3-Phase (2)
Active Active 3-Phase (3)
NOTE : Both Volt Select 1 and Volt Select 2 must be assigned to switched inputs. Otherwise the voltage sensing
will be disabled.
The below settings must be set. All except "Auto Single" are menus that contain four settings corresponding to the Volt Select
1 / Volt Select 2 inputs above.
Name Volt Select 2 Input
Genset Voltage > Auto Nominal These settings corresponds to the "Nominal Volts" setting under the AC Monitor > Genset
Voltage menu.
Genset Voltage > Auto Scaling These settings corresponds to the "Scaling Factor" setting under the AC Monitor > Genset
Voltage menu.
Genset Voltage > Auto Single Only applies when voltage sourc is set to 1-Phase 3-Wire. This determines which phases
the single phase voltage is read from: A-C or A-B.
Genset Current > Auto Rated These settings corresponds to the "Rated Amps" setting under the AC Monitor > Genset
Current menu.
Genset Current > Auto Scaling These settings corresponds to the "Scaling Factor" setting under the AC Monitor > Genset
Current menu.

Generator Frequency
Generator AC frequency display on the controller is enabled when the Voltage Source is not set to Disable.
The following settings are used to configure the controller's responses to frequency measurements.

This is the wiring configuration of the generator. Selecting Auto
Selection will use the
Frequency Select input to determine which
frequency is used.
This setting is used by the below setpoints. It does not affect the display
of AC Frequency.
