5.7.1 Voltage Connections,
Single-Phase Models
Single-phase generator sets are available from the
factory connected for 110/220 volt 50 Hz or 120/240 volt
60 Hz. See Figure 5-11 for the factory connections.
Generator sets are not reconnectable.

5.7.2 Voltage Connections, 3-Phase
Models
Three-phase model TRES generator sets are
connected for 230/400 Volts, 50 Hz. See Figure 5-12
for the factory connections. The generator sets are not
reconnectable.
Note: Current transformers (CTs) shown in Figure 5-12
are not used on these models.

5.7.3 Voltage Regulation
Voltage regulation is performed by the controller and the
SCR module. The controller monitors generator output
voltage and adjusts the excitation current to the rotor
through the SCR module. See Section 4.8, Silicon
Controlled Rectifier module.
5.8 Voltage Adjustment
(ADC-RES only)
The factory sets the voltage for correct generator
operation under a variety of load conditions. Usually,
the voltage needs no further adjustment.
Adjust the voltage when necessary according to the
following procedure. The adjustment procedure
requires a meter that can measure voltage and
frequency.
Use the ADC-RES controller keypad to adjust the
voltage, gain, and volts/Hz. This section contains
instructions to adjust each setting and save the changes
using the controller keypad.
